*🔴Bagolini striated lenses are used to evaluate:*
*🔴Correct Answer:* C) Central Suppression scotoma 🔴The reason it’s called a central suppression scotoma ,not just suppression , has to do with how the 4Δ Base-Out test works and what area of the retina is being tested:>> 1. The 4Δ prism displaces the image by a small amount , only about 2–3° of retinal angle. 2. That means it’s testing the eye's ability to fuse very centrally, right around the fovea. 3. So, if the eye doesn’t respond to that small image shift and shows no fusional movement, it suggests the brain is specifically suppressing the central area of that eye’s vision i.e., a central suppression scotoma. *If it were general suppression:* Larger image shifts or other binocular tests (like Worth 4 Dot at distance) would also show complete suppression, affecting both central and peripheral vision.

*🔴Correct Answer: Vitreous Hemorrhage ✅* *Let's Analyse* • *❌Retinal detachment* can occur in high myopes and cause sudden visual loss. • However, red reflex is usually present unless there's associated vitreous hemorrhage or media opacity. • Alone, RD does not usually block the red reflex, so this may not fully explain “no glow.” *Vitreous Hemorrhage [Correct Answer]✅* • Common in high myopes due to retinal tears or neovascularization. • Causes sudden vision loss. • Blood in the vitreous blocks light reflex, so no glow is seen on distant direct ophthalmoscopy. • Often, the posterior segment is not visible, only anterior segment seen.
