Retinal Degeneration: Key Insights for High Myopia Patients - Ophthalmology

Hello! Thank you for your detailed questions regarding retinal degeneration and high myopia. It’s important to understand the implications of these conditions, especially since you have been diagnosed with high myopia and have undergone a dilated fundus examination. Let’s address your concerns one by one.

1. Understanding the "White" Appearance of the Retina: When your doctor mentioned that the peripheral retina has become "white" and thinner, this could refer to a condition known as retinal atrophy. This atrophy can manifest as a grid-like pattern, which is often associated with degenerative changes in the retinal pigment epithelium and the outer layers of the retina. This change can be a sign of retinal degeneration, which is common in individuals with high myopia due to the elongation of the eyeball, leading to stretching and thinning of the retina.

2. Laser Treatment and Its Implications: The term "sacrifice" in the context of laser treatment refers to the fact that when laser photocoagulation is applied to the retina, it creates scar tissue that can indeed affect the visual field in that area. The goal of laser treatment is to prevent further complications, such as retinal detachment, but it can come at the cost of some visual function in the treated area. Your doctor’s decision to hold off on laser treatment suggests that they believe the risks of treatment currently outweigh the benefits. Typically, laser treatment is considered when there are signs of impending retinal detachment, such as the presence of tears or holes in the retina.

3. Risk of Retinal Detachment: Retinal detachment can occur suddenly, but it is often preceded by the development of tears or holes in the retina. In high myopia, the risk of retinal detachment is increased due to the structural changes in the eye. While not every case of retinal degeneration leads to detachment, it is crucial to monitor for symptoms such as flashes of light, an increase in floaters, or a shadow over your vision, as these can indicate a retinal tear or detachment.

4. Impact of Reading and Computer Use on Retinal Health: As a student in a technical field, you may find yourself spending long hours reading and using a computer. While this activity does not directly cause retinal degeneration, prolonged near work can lead to eye strain and fatigue, which may exacerbate any existing visual symptoms. It is essential to take regular breaks using the 20-20-20 rule: every 20 minutes, look at something 20 feet away for at least 20 seconds. This practice can help reduce eye strain and maintain comfort during extended periods of reading or screen time.

In summary, it is crucial to maintain regular follow-ups with your eye care provider to monitor the health of your retina, especially given your high myopia. If you notice any new symptoms or changes in your vision, do not hesitate to seek immediate medical attention. Understanding the nature of your condition and the potential risks involved will empower you to take proactive steps in managing your eye health. Thank you for your thoughtful questions, and I wish you the best in your studies and eye health!
