Good Vision Hides Hidden Eye Dangers
15 Oct
Summary
- Silent eye conditions can cause damage before symptoms appear.
- Glaucoma affects 3.23% of Indians aged 40+, rising by 2050.
- Regular eye exams detect disease, not just vision acuity.
Good eyesight can be misleading, as certain eye conditions may progress without any warning signs like pain or redness. Ophthalmologist Dr. Rishi Bhardwaj emphasizes that damage can be established before any noticeable difficulty arises, highlighting the critical role of regular eye examinations beyond just prescription checks.
Glaucoma, a prime example, damages the optic nerve gradually, often without early symptoms. Peripheral vision loss may occur while central vision remains unaffected. A review of Indian studies indicated a prevalence of 3.23% for glaucoma in individuals aged 40 and above, projected to increase by 2050.
Diabetic retinopathy also develops silently, stemming from high blood sugar damaging retinal blood vessels. Vision can remain normal during these early stages. For diabetics, regular retinal evaluations are essential, alongside managing blood glucose, blood pressure, and cholesterol to minimize visual impairment risks.
Comprehensive eye exams assess more than visual acuity. They evaluate eye pressure, optic nerve and retina health, and peripheral vision, using tools like retinal imaging and pupil dilation. These checks identify subtle structural or vascular changes, underscoring the importance of regular screenings for those with diabetes, a family history of glaucoma, or other risk factors.
