Vision and Intraocular Pressure

Dear Dr.
Gao,
I have myopia (right eye - 525 degrees, left eye - 600 degrees) and I also experience floaters.
In early October, I underwent a dilated OCT and visual field examination, and the doctor indicated that the overall condition of my eyes is normal.
I was advised to monitor my intraocular pressure, which was measured at around 23 mmHg, and I was prescribed eye drops for use and follow-up.
1.
I would like to know the appropriate timing for monitoring intraocular pressure.
Should I wait 28 days until I finish using the eye drops before returning for a follow-up, or is there a specific time frame for re-evaluation? Since intraocular pressure cannot be assessed based on subjective feelings, and the doctor did not specify when I should return, I would appreciate your guidance on when would be an appropriate time for the follow-up.
2.
This morning, I noticed a small black dot in my right eye, which I am certain is not a floater.
After blinking a few times, it disappeared (occasionally accompanied by a few faint light spots).
I tested it myself and found that this phenomenon does not occur when my eyes are open continuously; it only appears when I keep my right eye closed for about 10 seconds or more, and it lasts for about 2 to 3 seconds before disappearing.
I would like to know if this is typically a simple visual phenomenon, as the black dot is very small.
Thank you for taking the time to respond, Dr.
Gao.
I appreciate your help.

Hello Mr.
Chen:
1.
Intraocular pressure, like blood pressure, can fluctuate and varies at different times of the day.
If it is not well-controlled, more frequent monitoring may be necessary; however, if it is well-managed, longer intervals between check-ups can be acceptable.
Initially, when adjusting medication, more frequent measurements, such as once a week, are not excessive.
Since your visual field is normal and your optic nerve examination is likely normal as well, the doctor has advised you to finish your eye drops and return for a follow-up measurement.
If your intraocular pressure remains unstable, the doctor will shorten the follow-up intervals.
In summary, the doctor has not provided specific instructions other than to check again after you finish the eye drops.
2.
If the spots disappear and do not reappear, it may be a case of phosphenes.
However, if similar dark spots appear again, it could indicate floaters.
Overall, it should not be a cause for concern.

Hello! Thank you for your detailed questions regarding eye pressure, visual symptoms, and follow-up care. It's understandable to be concerned about your eye health, especially with your history of myopia and floaters. Let’s break down your questions and provide some clarity.

1. Follow-Up Timing for Eye Pressure: After starting eye drops for managing eye pressure, it is generally recommended to follow up with your eye doctor within 4 to 6 weeks. This allows enough time for the medication to take effect and for the doctor to assess whether your eye pressure has improved. Since you mentioned that your eye pressure was around 23 mmHg, which is on the higher side of normal, it’s crucial to monitor it closely. If you experience any new symptoms, such as changes in vision or discomfort, it would be wise to schedule an earlier appointment. Regular monitoring is essential, especially for individuals with a history of high eye pressure or glaucoma.

2. Visual Symptoms: The small black dot you noticed in your right eye could be related to several factors. Given that it disappears after blinking, it might be a transient visual phenomenon, possibly related to the way your eye is focusing or a temporary change in the tear film. This could also be a form of visual disturbance known as "phosphene," which can occur when pressure is applied to the eye or due to changes in light perception. However, if this symptom persists or worsens, it’s advisable to consult your eye doctor for a thorough examination. They can rule out any serious conditions, including retinal issues or changes in the vitreous gel that could lead to more significant problems.

3. Understanding Eye Pressure and Symptoms: Eye pressure is not always correlated with symptoms. Some individuals may have high eye pressure without noticeable symptoms, while others may experience discomfort or visual changes even with normal pressure. It’s important to remember that the sensation of pressure or discomfort in the eyes can also stem from other conditions, such as dry eyes, eye strain, or even allergies. Therefore, regular check-ups and open communication with your eye care provider are vital for managing your eye health.

4. Managing Anxiety About Eye Health: It’s natural to feel anxious about potential eye conditions, especially with your background of myopia and floaters. However, focusing on what you can control—such as adhering to prescribed treatments, maintaining regular follow-ups, and practicing good eye hygiene—can help alleviate some of that anxiety. Engaging in relaxation techniques or discussing your concerns with your healthcare provider can also be beneficial.

5. Importance of Eye Drops: If your doctor prescribed eye drops, it’s crucial to use them as directed. These medications are designed to help lower eye pressure and protect your optic nerve from potential damage. If you notice any side effects or if your symptoms change, be sure to report this to your doctor.

In summary, keep track of your symptoms, adhere to your follow-up schedule, and maintain open communication with your eye care provider. If you have any new or worsening symptoms, don’t hesitate to seek medical advice sooner. Your proactive approach to your eye health is commendable, and with regular monitoring and care, you can manage your condition effectively. Thank you for your questions, and I hope this information helps clarify your concerns!
