Eye Fatigue and Risks for High Myopia Patients - Ophthalmology

More Info

---

High myopia, or severe nearsightedness, is a condition where the eyeball is elongated, leading to various ocular complications. As a patient with high myopia, your concerns about eye fatigue, visual discomfort, and the potential risks associated with your condition are valid and important to address.

Firstly, regarding your question about whether reducing your myopia degree can lower the risk of eye diseases: While there is some evidence that controlling myopia progression can reduce the risk of associated complications, such as retinal detachment, glaucoma, and cataracts, it is essential to understand that the risk does not disappear entirely. Even with a reduction in myopia, the structural changes in the eye that predispose you to these conditions may still exist. Regular eye examinations and monitoring by an eye care professional are crucial to managing your eye health effectively.

Now, concerning your symptoms of discomfort and sensitivity to light, particularly when reading or driving at night, these could indeed be signs of eye fatigue. Eye fatigue, or asthenopia, can occur due to prolonged use of digital devices, reading, or any activity that requires intense focus. Symptoms often include discomfort, dryness, blurred vision, and sensitivity to light. If you have been engaging in activities that require prolonged visual concentration, it is likely that your eyes are experiencing fatigue.

The sensation of seeing halos or glare around lights, especially at night, can also be associated with high myopia. This phenomenon occurs due to the way light is refracted in the eye, particularly if there are any changes in the cornea or lens. In high myopia, the risk of developing cataracts or changes in the vitreous can contribute to these visual disturbances. It is essential to discuss these symptoms with your eye care provider, as they may want to perform a comprehensive examination to rule out any underlying conditions.

Regarding your concern about elevated intraocular pressure (IOP), it is important to note that while high myopia itself does not directly cause high IOP, the two can be related. Elevated IOP can lead to glaucoma, a serious condition that can result in vision loss if not managed appropriately. If you have a history of fluctuating IOP or have been diagnosed with ocular hypertension, it is crucial to follow your doctor's recommendations regarding medication and regular check-ups.

In summary, while reducing myopia can potentially lower the risk of certain eye diseases, it does not eliminate the risk entirely. Your symptoms of light sensitivity and discomfort may be related to eye fatigue, but they could also indicate other underlying issues that warrant further investigation. It is advisable to maintain regular follow-ups with your eye care provider, especially given your history of high myopia, to monitor your eye health and address any emerging concerns promptly. Additionally, consider implementing strategies to reduce eye strain, such as taking regular breaks during prolonged visual tasks, ensuring proper lighting, and using artificial tears to alleviate dryness.
