Macular Degeneration Treatment in Ranchi
Expert care for age-related macular degeneration (ARMD) by Dr. Dibya Prabha — Retina Specialist — at Neurovision Clinic. Advanced anti-VEGF therapy with OCT-guided monitoring.
What is Age-Related Macular Degeneration (ARMD)?
Age-Related Macular Degeneration (ARMD) is a degenerative eye disease that affects the macula — the small, central portion of the retina responsible for sharp, detailed central vision needed for reading, driving, recognizing faces, and seeing fine details. In ARMD, the macula gradually deteriorates. There are two forms: 'dry' (atrophic) ARMD, accounting for about 90% of cases, involves slow thinning of macular tissue and the buildup of drusen (yellow fatty deposits); 'wet' (neovascular or exudative) ARMD, while less common, is more aggressive — abnormal blood vessels grow beneath the macula (choroidal neovascularization), leaking fluid and blood, causing rapid and severe central vision loss. ARMD is the leading cause of severe vision loss in people over 50 in developed countries. It does NOT cause total blindness (peripheral vision is preserved) but profoundly affects quality of life.
Symptoms of Age-Related Macular Degeneration (ARMD)
- •Gradual or sudden loss of central vision — the ability to see fine details straight ahead
- •Distorted vision — straight lines appear wavy or bent (metamorphopsia)
- •Blurred or dark areas in the center of vision
- •Difficulty reading, recognizing faces, or performing detailed tasks
- •Decreased brightness of colors
- •Increased difficulty adapting to low light levels
- •Need for brighter light when reading or doing close work
- •Visual hallucinations in advanced cases (Charles Bonnet syndrome)
Causes & Risk Factors
- •Age — the biggest risk factor; ARMD is rare before age 50, common after 60, and prevalence increases with each decade
- •Genetics — family history significantly increases risk; several genes associated with ARMD have been identified
- •Smoking — the most important modifiable risk factor; smokers have 2-4 times higher risk
- •Race — more common in Caucasians than in other ethnic groups
- •Cardiovascular disease and high blood pressure
- •Obesity and poor diet (low in antioxidants and omega-3 fatty acids)
- •Prolonged unprotected UV light exposure
- •Light-colored irises (blue or green eyes) may have slightly higher risk
Diagnostic Tests
OCT (Optical Coherence Tomography)
The essential imaging tool for ARMD. High-resolution cross-sections of the macula detect fluid, drusen, and retinal thinning. Essential for diagnosing wet ARMD and monitoring treatment response.
OCTA (OCT Angiography)
Non-invasive imaging of retinal blood flow that can detect abnormal choroidal neovascularization (the hallmark of wet ARMD) without dye injection.
Fundus Photography
Color retinal imaging to document drusen, pigment changes, hemorrhage, and other ARMD features for long-term monitoring.
Treatment Approach
Dr. Dibya Prabha provides comprehensive, individualized ARMD care based on the type and stage of the disease:
Anti-VEGF Intravitreal Injections (Wet ARMD)
The standard of care for wet ARMD. Medications (ranibizumab, aflibercept, bevacizumab) injected into the eye block vascular endothelial growth factor, stopping abnormal blood vessel growth and leakage. This dries the retina and preserves or improves vision. Dr. Prabha uses a treat-and-extend protocol — starting with monthly injections, then gradually extending the interval based on OCT findings.
AREDS2 Nutritional Supplementation (Dry ARMD)
For moderate to advanced dry ARMD, specific high-dose antioxidant vitamins and minerals (vitamins C and E, lutein, zeaxanthin, zinc, copper) per the AREDS2 formula can reduce the risk of progression to advanced ARMD by about 25%.
Lifestyle Optimization
Smoking cessation counseling, UV-protective sunglasses, a diet rich in green leafy vegetables and omega-3 fatty acids, blood pressure control, and maintaining a healthy weight — all proven to slow ARMD progression.
OCT-Guided Monitoring
Regular OCT imaging (every 4-12 weeks depending on stage and treatment intensity) to detect early fluid recurrence and guide re-treatment decisions. Amsler grid home monitoring is taught to detect changes between visits.
⚠️ When to See a Doctor
- !If you notice any distortion in your central vision — wavy or bent straight lines
- !If you experience a gradual or sudden decline in central vision
- !If colors appear less vivid than before
- !Annually after age 50 — comprehensive eye exam with retinal evaluation
- !If you have a family history of ARMD — begin screening at an earlier age
- !If you are a smoker or former smoker — screening is especially important
