Retinal issues?


Hello Doctor: I underwent laser surgery for a retinal tear in 2008 and have been monitoring my eye condition since then (I am nearsighted with -7.00 diopters).
Recently, due to work-related fatigue, I suddenly noticed a shadow in my right eye one night, and my vision became blurry for about a minute.
Although the symptoms disappeared by morning, I immediately went to the Tri-Service General Hospital in Neihu for an examination (attending physician: Dr.
Zhang Yunxiang).
After dilation, the doctor found no abnormalities and advised further observation.
However, I am extremely worried.
I would like to ask the doctor: 1.
Is this condition a precursor to retinal detachment? If not, why did the symptoms suddenly disappear? 2.
Is there still a risk of detachment after having undergone laser surgery for a retinal tear? 3.
I practice yoga; does the downward-facing dog pose (bending forward) pose any risks? Thank you.

Dr. Cai Wenyuan reply Ophthalmology


Hello: It's good that the examination showed no abnormalities, so there's no need for special concern.
As long as the tear is not large, the chance of detachment after laser treatment is minimal.
Please follow the doctor's advice and attend regular check-ups.
Wishing you safety and health.
Sincerely, Dr.
Tsai Wen-Yuan, Director of Ophthalmology, Taoyuan General Hospital, Ministry of Health and Welfare.

Understanding retinal issues, especially for individuals with a history of retinal surgery and high myopia, is crucial for maintaining eye health. Your concerns about the symptoms you experienced, the potential for retinal detachment, and the safety of practicing yoga are valid and deserve thorough consideration.

1. Symptoms and Retinal Detachment: The sudden appearance of a shadow or black spot in your vision, accompanied by blurred vision, can indeed be alarming. These symptoms can sometimes indicate retinal detachment or other serious retinal issues. However, the fact that these symptoms resolved quickly and that your eye examination showed no abnormalities is reassuring. Temporary visual disturbances can occur due to various benign reasons, such as vitreous floaters or transient ischemic attacks affecting the retina. The sudden disappearance of symptoms may suggest that it was not a serious issue, but rather a transient event. Nonetheless, it is essential to remain vigilant and report any recurrence of symptoms to your eye care professional.

2. Risk of Retinal Detachment Post-Laser Surgery: Having undergone laser surgery for a retinal tear does not eliminate the risk of future retinal detachment, especially in individuals with high myopia. High myopia is associated with structural changes in the eye that can predispose individuals to retinal issues, including detachment. However, the laser treatment you received is designed to reduce the risk of detachment by sealing the retinal tear and preventing fluid from entering the subretinal space. Regular follow-up examinations are crucial to monitor the health of your retina, especially given your history and the degree of myopia.

3. Yoga and Eye Safety: Regarding your practice of yoga, particularly poses like Downward Dog, it is important to approach these activities with caution. Certain yoga positions can lead to changes in intraocular pressure or strain on the eyes, which may be a concern for individuals with high myopia or a history of retinal issues. While gentle stretching and non-inverted poses are generally safe, it is advisable to avoid positions that involve significant bending or inversion, especially if you experience any discomfort or visual changes during practice. Listening to your body and modifying poses as needed can help mitigate risks.

In summary, while your recent symptoms may not indicate an immediate threat, it is essential to remain proactive about your eye health. Continue to follow up with your eye care provider, adhere to their recommendations, and do not hesitate to seek medical attention if you experience any new or worsening symptoms. Practicing yoga can be beneficial for overall well-being, but be mindful of how your body responds and adjust your practice accordingly. Regular eye examinations and open communication with your healthcare provider are key to managing your eye health effectively.
