Eye Discomfort and Brightness Perception Issues - Ophthalmology

Foreign body sensation in the eyes and issues with visual brightness?


Hello Dr.
Tsai, I have a few questions I would like to ask you:
1.
For the past six months, I have frequently felt a foreign body sensation in my left or right eye.
When I look in the mirror, I notice some oily substances accompanied by small particulate matter floating on the cornea when I blink.
No matter how much I rinse with saline solution, I cannot wash away these small particles.
Sometimes, I even experience some blurriness.
I have visited the clinic multiple times, and most doctors say it is caused by dry eyes (but I am not sure if it is dry eye syndrome).
They usually prescribe anti-inflammatory eye drops or lubricating eye drops.
Aside from the medications prescribed by the clinic, are there any other ways to improve this condition?
2.
During the foreign body examination, my eyelid is flipped to check, but during this process, I feel pressure on my eyeball.
Does this pose any risk of damage to the retina?
3.
I have high myopia (left eye -775, right eye -650), and in the past year, I have had two or three dilated fundus examinations, all of which showed normal retinal condition (though some liquefaction has caused floaters).
Sometimes, when I stare at a white or other solid-colored wall, I feel that the brightness at the center of my vision appears darker, but when I look down, the brightness seems normal.
Is this situation considered normal?
I apologize for the numerous questions, and I appreciate your time in addressing my concerns.

Hello! Thank you for your detailed questions regarding your eye discomfort and brightness perception issues. I understand that these concerns can be quite distressing, especially when they affect your daily life and work. Let’s address your questions one by one.

1. Foreign Body Sensation and Dry Eyes: The sensation of having something in your eye, along with the presence of small particles that seem to float on the cornea, can indeed be associated with dry eye syndrome. This condition occurs when your eyes do not produce enough tears or when the tears evaporate too quickly. While saline solutions and prescribed anti-inflammatory drops can help, there are additional strategies you can employ to alleviate your symptoms. Consider using artificial tears more frequently, especially those that are preservative-free, as they can provide longer-lasting relief. Additionally, maintaining a humid environment, taking regular breaks from screens (the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds), and ensuring proper hydration can also help. If your symptoms persist, it may be worthwhile to consult with an ophthalmologist who specializes in dry eye disease for a more tailored treatment plan, which might include punctal plugs or other therapies.

2. Pressure During Eye Examinations: When your eyelid is flipped during an examination, it can indeed create a sensation of pressure on the eyeball. However, this procedure is generally safe and should not cause harm to the retina or other structures of the eye. Ophthalmologists are trained to perform these examinations carefully to minimize discomfort and risk. If you experience significant pain or discomfort during the examination, it is important to communicate this to your doctor, as they can adjust their technique or provide additional support.

3. Brightness Perception Issues: The phenomenon you describe, where the brightness appears different depending on where you are looking, can be related to several factors. In individuals with high myopia (like yourself), the retina can sometimes exhibit variations in sensitivity to light, especially in the presence of conditions like retinal thinning or liquefaction, which you mentioned. This can lead to areas of the visual field appearing darker or lighter depending on the surrounding light conditions. While this can be concerning, it is not uncommon for those with high myopia. However, if you notice significant changes in your vision or if these symptoms worsen, it is crucial to follow up with your eye care provider for further evaluation.

In summary, while some of your symptoms may be related to dry eye syndrome and the effects of high myopia, it is essential to maintain regular check-ups with your eye care professional. They can monitor your condition and provide appropriate interventions as needed. If you feel that your current treatment is not effective, do not hesitate to seek a second opinion or ask for a referral to a specialist. Your eye health is important, and addressing these concerns early can help prevent more serious issues down the line. Thank you for your questions, and I hope this information helps clarify your concerns!
