## What The Sources Report

- Major vision-threatening conditions such as glaucoma, cataracts, age-related macular degeneration (AMD), diabetic retinopathy (DR), uveitis, retinal detachment, etc., contribute significantly to functional disability and reduced quality of life. [De Silva Sandun (2026); evidence level 4]
- Oxidative stress, chronic inflammation, mitochondrial dysfunction, dysregulated angiogenesis and metabolic imbalance are highly associated with the molecular-level pathogenesis of these ocular diseases. [De Silva Sandun (2026); evidence level 4]
- Although this form is less common, it is associated with a poorer prognosis and accounts for nearly 80% of severe vision loss caused by AMD. [Muacevic Alexander (2026); evidence level 4]
- The study concluded that consumption of the AREDS formula reduced the risk of progression by 25% over five years in patients with intermediate AMD or advanced disease in one eye. [Muacevic Alexander (2026); evidence level 4]

## How To Read This Evidence

Evidence level 1 generally reflects systematic reviews or meta-analyses. Level 2 includes randomized trials, guidelines, or public-health guidance. Level 3 usually reflects observational or narrative-review evidence. Level 4 is weaker or early-stage evidence. The level is a sorting aid, not a final quality grade.

## Practical Interpretation
