Post-operative care after retinal laser treatment?

Hello, Doctor.
I underwent retinal laser treatment on both eyes at the end of January and returned for a follow-up in late February.
The doctor informed me that the treated areas were stable, which relieved my anxiety.
The doctor also specifically instructed me to return for an examination if I experienced new floaters.
I had previously asked you some questions, but I still have a few more inquiries, as I sometimes realize there are additional concerns only after encountering or thinking about them (and I couldn't find answers online).
I hope you can understand.
1.
The occurrence of retinal detachment is primarily due to fluid entering through a tear or external force.
What are the causes that can lead to the formation of retinal tears? I understand that vitreous degeneration and traction, external trauma (like a hit), and sudden exertion can contribute.
Does eye fatigue from reading or using electronic devices also lead to tears? I am currently taking lutein, astaxanthin, anthocyanins, multivitamins, and fish oil, but I'm unclear if these can reduce the likelihood of tears.
(I know lutein protects the macula, and astaxanthin and anthocyanins can penetrate barriers in the retina, ciliary body, lens, etc., based on information I found online.)
2.
After applying a warm compress at about 35-40 degrees Celsius to my eyes, my vision becomes hazy for a while.
Is this normal? (My mother used to experience hazy vision and a feeling of pressure after warm compresses.)
3.
After my follow-up, the doctor mentioned that if I see dark spots appearing in the area where the laser was applied, I should return immediately.
I would like to know if the scabbed area from the laser treatment can potentially fall off once it stabilizes.
The doctor's statement made me a bit anxious...
Is the laser applied in a U-shape rather than a complete circle, so if fluid enters, it would overflow?
4.
Elevated intraocular pressure can lead to glaucoma and may also cause retinal tears.
How can I initially assess if my eye pressure is elevated? (I know some people suggest using their hands to feel, but I’ve seen you mention that this is very inaccurate.) If I feel pressure in my eyes, have a foreign body sensation, notice conjunctival injection, and most importantly, experience hazy vision, do these symptoms indicate that I should rest my eyes?
5.
I don't quite understand how much force is required to cause a tear or detachment, and I couldn't find a reference chart online.
Would actions like gently touching my eyelids while washing my face, sleeping on one side with pressure on that eye, or lying down while using my phone impact this? (I personally feel that it could cause slight deformation of the eyeball, similar to pressing on a boiled egg with a finger, but I'm not sure if that's correct.)
6.
When I have free time, I focus my eyes straight ahead and extend my arm to trace the periphery of my vision with my finger (keeping my gaze forward and using peripheral vision to see my finger).
Is this method helpful for me to preliminarily assess if there are any detachments in my peripheral retina?
7.
The doctor advised that if I notice new floaters or if existing floaters increase in size, I should return for a check-up.
However, I already have a significant number of floaters in my field of vision...
Is it possible to clearly identify if a new floater has appeared?
8.
Due to my Tourette syndrome, I cannot control certain movements, specifically nodding and forceful blinking.
I would like to know if the act of nodding can affect my eyes.
Could it indirectly cause traction on the vitreous? My nodding is not very forceful, but sometimes I blink hard or even close my eyes while blinking (which sounds strange, but I use the muscles for blinking even when my eyes are closed, similar to forcefully closing my eyes).
I'm worried that this could cause issues with my eyeballs.
9.
I have difficulty concentrating due to my Tourette syndrome, but I need to prepare for exams, so I have been taking Adderall.
Will this medication affect my eyes?
10.
I found information suggesting that drinking soy milk and consuming soy products can increase intraocular pressure.
Is this true? Could it lead to the formation of tears?
11.
As a person with high myopia, does performing eye exercises, such as straining to look left and right or rotating my eyes, put pressure on my eyeballs? If the eye socket is round and myopic eyes are oval, would these exercises slightly compress the eyeball?
12.
A month after the laser treatment, I have become accustomed to the partial vision loss from the laser.
Besides experiencing fatigue and dryness (which I may have had before, but I’m now more aware of it post-laser), I often get startled by my eyelashes, thinking my vision is impaired.
I want to start exercising (as my physical condition has declined).
Is jogging for half an hour suitable? Can I engage in aerobic exercises?
13.
The eye drops I am currently using include: (1) Methacholine sulfate eye drops (the label says to use three times a day after meals and before bed), (2) Sato Vision eye drops NOARLA (which contains B6 and B12, feeling like an advanced version of Sankaba), and (3) Urisu moisturizing single-dose eye drops (artificial tears).
I usually use artificial tears for dryness and Sato eye drops after reading or studying.
However, I’m unsure when to use the methacholine drops.
Can I use them five minutes apart from the Sato and artificial tears, or can I use them whenever I feel fatigued? The label suggests three times a day, which feels like a cold medicine...
The doctor mentioned it's for maintenance, and I found online that it relaxes muscles (but I don’t know which muscles).
I have no idea when to use them; should I just use them before bed?
14.
Should I consider buying sunglasses to wear when going out? I remember seeing on a Japanese medical program that deep black sunglasses can cause the pupils to dilate, potentially harming the eyes.
Is this true?
15.
I often wake up with dry eyes.
Would wearing an eye mask while sleeping help alleviate this issue? Should I choose a specific type of mask? I’m concerned it might press on my eyeballs, and I’ve read that it could affect eye movement during REM sleep, leading to health issues.
Or is it sufficient to apply a warm compress to my eyes before bed?
16.
Massaging around the eyes (as mentioned in traditional Chinese medicine) should not affect the eyeball, right? I used to feel discomfort around my eyes the next day after massaging, which I believe is muscle-related.
I often hear that this can help relax the eyes.
17.
Sometimes after reading or looking at a screen for a short period, I feel a slight soreness in my eye sockets.
Could this be a symptom of dry eye syndrome? Does this indicate that I should apply a drop of artificial tears?
18.
Since I have several pets at home and the air quality is poor, my eyes sometimes become very itchy (allergic reaction?).
Could this situation affect my eyeballs? (I’m worried it might indirectly lead to retinal tears.) While the 2% Systane eye drops alleviate the itching, could they also negatively impact my eyes (like increasing intraocular pressure)?
19.
To stay alert, I sometimes drink coffee or energy drinks containing taurine.
Will this affect my eyes? Are there any dietary restrictions for someone with high myopia and retinal tears?
Thank you very much, Doctor, for taking the time to answer my numerous questions despite your busy schedule.
I have always had an avoidance mentality regarding eye issues until a month ago when I finally faced them.
Although I know that once the laser scab stabilizes, I shouldn't worry too much, the tears are still there, and the laser-treated area feels somewhat like frosted glass (the doctor mentioned I am sensitive to my peripheral vision).
Sometimes, when I close my eyes, I notice flashes in the laser-treated area, as you mentioned, and the brightness and range have significantly decreased compared to before.
However, occasionally, my right eye still experiences brief flashes in the laser area (especially when my eyes are tired).
I initially planned to visit your hospital for a consultation, but after checking the location, I realized it might be a bit far from Taoyuan...

Hello: 1.
The formation of retinal tears is usually caused by uneven traction within the eye, with the most common reason being vitreous contraction and thickening of the retinal membrane due to aging.
Other causes may include external trauma or impact to the eye, ocular diseases (such as myopia, glaucoma, diabetic retinopathy, etc.), eye surgeries, or treatments for eye diseases.
Currently, there is no evidence that prolonged reading or the use of electronic devices directly leads to retinal tears.
Nutritional supplements such as lutein, astaxanthin, anthocyanins, multivitamins, and fish oil may help protect eye and retinal health, but they cannot directly prevent or treat tears.
2.
Blurred vision and a feeling of pressure in the eyes after applying a warm towel may be normal reactions, but this should return to normal shortly after the heat application ends.
If these symptoms persist for a longer duration or are accompanied by other ocular symptoms (such as vision loss, pain, redness, etc.), it is advisable to seek medical attention promptly.
3.
After laser treatment, a thicker scab layer usually forms in the treatment area, which is typically stable during the healing process.
If the scab changes after treatment, such as becoming dark or exhibiting other abnormalities, this may indicate a problem in the treatment area, and medical evaluation should be sought promptly.
4.
Elevated intraocular pressure can be a significant cause of glaucoma, thus early detection and treatment are essential.
The best way to initially assess elevated intraocular pressure is through regular measurements and examinations by an ophthalmologist.
Generally, professional intraocular pressure measurements require the use of specialized tonometers, as manual methods are not accurate.
Elevated intraocular pressure may not always present obvious symptoms, making regular eye examinations crucial.
Possible symptoms include: headaches or eye pain, blurred or deteriorating vision, a feeling of heaviness or fatigue in the eyes, redness or vascular dilation, and constricted or abnormal visual fields.
If these symptoms occur, it is recommended to seek medical attention immediately to detect and treat issues caused by elevated intraocular pressure early.
Additionally, good eye care and stress avoidance can help prevent elevated intraocular pressure.
5.
Retinal tears and detachments are very serious ocular conditions and generally do not occur due to normal contact in daily life.
The structure of the eye is fragile and requires special care.
When washing the face, avoid letting facial cleansers enter the eyes; rinsing with clean water is recommended.
When sleeping on one's side, avoid direct contact of the eyes with the pillow, and consider using special sleep masks or pillows to protect the eyes.
When using a mobile phone, adjust the screen brightness and distance appropriately, and avoid staring at the screen for extended periods.
If symptoms such as eye pain, blurriness, or vision loss occur, seek medical attention promptly for an eye examination to determine if there are serious issues like retinal tears or detachments.
It is best to follow the advice and instructions of an ophthalmologist to ensure eye health and safety.
6.
This method cannot help in the initial assessment of peripheral retinal detachment, as it cannot detect retinal detachment.
If you suspect you have an eye problem, it is best to visit an ophthalmologist for examination.
An ophthalmologist will use specialized examination tools and techniques, such as fundus examination and ultrasound, to assess the condition of the eyes and diagnose and treat based on the findings.
Timely medical attention is crucial if there are concerns about retinal detachment to prevent irreversible vision damage.
7.
The appearance of new floaters may be difficult to identify as new.
Generally, when new floaters appear, they may feel more pronounced or sudden, possibly accompanied by flashes or blurred vision.
If you notice any abnormalities or new symptoms, it is advisable to return for an examination as soon as possible.
8.
Generally, nodding does not directly affect the eyes, and blinking does not directly exert traction on the vitreous.
However, if your blinking is excessively forceful or prolonged, it may lead to eye fatigue or discomfort, potentially even causing dry eye syndrome.
Therefore, it is recommended to take breaks and avoid prolonged forceful blinking to prevent eye fatigue.
9.
Methylphenidate is a medication used to treat Attention Deficit Hyperactivity Disorder (ADHD).
Its primary action is to regulate neurotransmitters such as dopamine and norepinephrine in the brain to enhance attention and concentration.
Methylphenidate itself does not have a significant impact on the eyes, but some individuals may experience side effects such as headaches or eye fatigue, which could affect learning and testing performance.
If you experience any discomfort, it is advisable to inform your physician for adjustments or alternative treatment options.
10.
Currently, there is insufficient scientific evidence to suggest that soy milk or soy products directly cause elevated intraocular pressure or the occurrence of tears.
11.
Eye exercises are a form of ocular movement that can promote blood circulation in the eyes and adjust the focal length, which may help improve vision.
For individuals with high myopia, it is important to perform eye exercises moderately, avoiding excessive force or prolonged eye movements, as overexertion or extended eye movements may increase intraocular pressure or cause eye fatigue, leading to adverse effects on eye health.
As for the shape of the eye socket and eyes, individual conditions may vary; generally, eye exercises should not exert pressure on the eyeball.
12.
Typically, one month after laser surgery is sufficient for engaging in light aerobic exercise.
Jogging for half an hour is a good choice, as it can enhance cardiovascular function and boost metabolism.
Additionally, other aerobic exercises such as walking, cycling, and swimming are also good options.
13.
Regarding the timing of eye drops, each type of eye medication has its own usage timing and frequency; please follow the instructions on the package insert for each eye drop.
Generally, you can decide whether to use eye drops based on your symptoms, such as using moisturizing eye drops like Systane or Sato's NOARLA when experiencing eye fatigue or dryness.
Please note that overusing eye drops may lead to adverse reactions, so it is essential to use them according to the instructions.
If you have any questions or need further advice, please consult your physician or pharmacist.
14.
Wearing sunglasses can help reduce UV damage to the eyes, which is especially important for patients who have undergone laser surgery.
It is recommended to choose sunglasses with UV400 protection, which can effectively prevent UV damage.
Additionally, if you frequently engage in outdoor activities, consider selecting larger frames and lenses to cover more of the eye area for comprehensive protection.
Regarding the color of sunglasses, generally, darker lenses absorb more light, which can reduce eye irritation, but they may also cause the pupils to dilate more, allowing more harmful light to enter the eyes.
Therefore, it is advisable to choose lighter-colored lenses, such as gray, green, or brown, which can provide adequate protection without causing excessive pupil dilation.
15.
Wearing an eye mask can help avoid light stimulation and reduce discomfort caused by light exposure.
However, when choosing an eye mask, opt for a softer material that does not exert pressure on the eyeball to avoid compromising eye health.
Additionally, wearing an eye mask may affect rapid eye movement (REM) during sleep, but this usually does not have significant health implications.
If you are concerned about this issue, you may choose a thinner eye mask or forgo the mask altogether, opting for other methods such as warm compresses before sleep or avoiding screens to alleviate dryness in the eyes.
16.
Massaging around the eyes generally does not directly affect the eyeball, but if the pressure is too strong or the technique is improper, it may compress or irritate surrounding muscles, nerves, and blood vessels, leading to discomfort around the eyes.
Furthermore, if symptoms such as pain, redness, or itching occur around the eyes, it is advisable to stop the massage and consult a physician.
17.
The symptoms you describe may be indicative of dry eye syndrome; it is recommended to use artificial tears to alleviate the symptoms.
However, it may also be due to prolonged focus on books or computer screens causing eye fatigue; in this case, try performing eye exercises or taking breaks to improve the symptoms.
18.
Your itchy eyes may be due to irritation from allergens.
This is common in households with multiple pets and poor air quality.
Itchy eyes typically do not directly affect the eyeball, but excessive rubbing or scratching may lead to eye infections or other ocular issues.
Using eye drops to relieve itching is a good idea, but it is important to follow the advice of your doctor or pharmacist.
Antihistamine eye drops like Pataday can alleviate allergic reactions and typically do not affect intraocular pressure.
19.
Drinking coffee or energy drinks usually does not directly affect the eyes, but the caffeine or other stimulants they contain may cause vasodilation in the body, potentially affecting the blood vessels in the eyes.
For individuals with high myopia and retinal tears, excessive intake of caffeine or other stimulants may increase the risk of retinal tears.
Therefore, it is advisable to limit the intake of caffeine or energy drinks containing taurine or choose other beverages that do not negatively impact eye health.
In addition to caffeine and energy drinks, it is recommended to avoid foods high in sugar, fat, and salt, as these may have adverse effects on eye health.
Additionally, you can choose foods rich in vitamins A, C, E, and omega-3 fatty acids that are beneficial for eye health, such as carrots, spinach, tomatoes, and nuts.

Post-retinal laser treatment care is crucial for ensuring optimal recovery and minimizing complications. Here are some essential tips and common concerns regarding your situation:
1. Causes of Retinal Tears: Retinal tears can occur due to various factors, including vitreous detachment, trauma, or extreme physical exertion. While activities like reading or using electronic devices can cause eye strain, they are not typically direct causes of retinal tears. However, maintaining good eye health through proper nutrition, such as consuming lutein, astaxanthin, and anthocyanins, may help support retinal health, although they cannot guarantee the prevention of tears.

2. Heat Compress Effects: It is normal to experience temporary blurriness after applying a warm compress to your eyes. The warmth can cause blood vessels to dilate, leading to a sensation of pressure or swelling. If this sensation persists or worsens, consult your eye care provider.

3. Laser Treatment Healing: After laser treatment, the area may form a scab-like tissue that can appear darker. It is generally stable, but if you notice any changes, such as new dark spots or increased floaters, it is essential to return to your doctor for evaluation. The laser treatment does not create a barrier but rather reinforces the retina, so it is crucial to monitor for any signs of complications.

4. Monitoring Eye Pressure: Elevated eye pressure can lead to glaucoma and may contribute to retinal issues. Symptoms of increased pressure can include a feeling of fullness or pressure in the eye, redness, and blurred vision. However, the best way to assess eye pressure is through a professional examination, as self-assessment methods are not reliable.

5. Understanding Forces on the Eye: The force required to cause retinal tears varies significantly among individuals. Light pressure from washing your face or resting your head on a pillow is unlikely to cause damage. However, sudden, forceful movements or trauma can pose a risk. It is essential to be cautious during activities that may exert pressure on the eyes.

6. Vision Testing Techniques: Your method of checking for visual field defects by focusing straight ahead and using peripheral vision to observe your fingers is a reasonable preliminary check. However, it is not a substitute for professional testing.

7. Identifying New Floaters: Distinguishing between existing and new floaters can be challenging, especially if you have a significant number of floaters. If you notice any sudden changes, such as an increase in floaters or flashes of light, seek immediate medical attention.

8. Impact of Tics on Eye Health: Your tics, such as nodding or forceful blinking, are unlikely to cause direct harm to the retina. However, if you experience discomfort or changes in vision, it is advisable to discuss these symptoms with your eye care provider.

9. Medication Effects: Medications like Adderall (used for ADHD) can have side effects, including potential impacts on eye health. If you notice any changes in your vision or eye comfort after starting this medication, consult your doctor.

10. Diet and Eye Health: While some anecdotal evidence suggests that soy products may affect eye pressure, scientific consensus is lacking. Maintaining a balanced diet rich in antioxidants and omega-3 fatty acids is generally beneficial for eye health.

11. Eye Exercises: While gentle eye exercises may help relieve strain, they should not involve excessive force. If you have concerns about eye pressure or strain, consult your eye care professional for personalized advice.

12. Exercise Post-Laser Treatment: Engaging in moderate aerobic exercise, such as jogging, is typically safe after a month post-laser treatment, but always follow your doctor's specific recommendations.

13. Eye Drop Usage: Follow the prescribed schedule for your eye drops. It is generally safe to space out different eye drops by a few minutes. If you experience discomfort or have questions about specific drops, consult your doctor.

14. Sunglasses: Wearing sunglasses outdoors is advisable to protect your eyes from UV rays. Choose sunglasses that block 100% of UVA and UVB rays, and avoid overly dark lenses that can cause pupil dilation.

15. Eye Masks: Using an eye mask while sleeping can help with dryness, but ensure it is not too tight. A mask that allows for some airflow is ideal.

16. Eye Massage: Gentle massage around the eyes can relieve tension, but avoid applying pressure directly on the eyeball.

17. Eye Strain Symptoms: If you experience discomfort after prolonged screen time, it may indicate dry eye or eye strain. Using artificial tears can help alleviate these symptoms.

18. Allergies and Eye Health: Allergies can cause itching and discomfort but are unlikely to lead to retinal tears. If you experience severe symptoms, consider discussing allergy management with your healthcare provider.

19. Caffeine and Eye Health: Moderate caffeine consumption is generally safe for eye health, but excessive intake may lead to dehydration, which can exacerbate dry eye symptoms.
In summary, maintaining regular follow-ups with your eye care provider is essential for monitoring your condition post-laser treatment. Address any new symptoms promptly and adhere to your prescribed care regimen for optimal recovery.
