What interim medical treatment is used while awaiting vitrectomy for a dropped nucleus?
Topical corticosteroids and aqueous suppressants control inflammation and intraocular pressure in the interval before definitive surgical removal of the retained material.
Retained Lens Fragments: When the Nucleus Drops Into the Vitreous
Which symptom pattern is characteristic of posterior subcapsular cataract?

Cataract Morphology: Why Where the Lens Clouds Matters as Much as That It Does
Which slit-lamp technique best reveals the fine fingerprint lines of map-dot-fingerprint dystrophy?
The curvilinear fingerprint lines are often invisible on routine direct illumination and are best appreciated with retroillumination against the red reflex or broad tangential illumination.
Map-Dot-Fingerprint Dystrophy: The Hidden Cause of Recurrent Erosion
Which connective tissue disorders cause generalised zonular weakness with ectopia lentis?
Marfan syndrome and homocystinuria are the connective tissue disorders named as causing generalised zonular weakness and ectopia lentis.
Zonular Dehiscence During Cataract Surgery: Managing a Weakened Foundation

The surgeon lifts the flap and scrapes epithelium from both the stromal bed and the underside of the flap before careful repositioning, sometimes adding sutures, fibrin glue or a bandage lens to prevent recurrence.
Epithelial Ingrowth After LASIK: When Cells Grow Where They Don’t Belong
How does compression at an arteriovenous crossing lead to branch retinal vein occlusion?
Compression at the crossing increases turbulence and endothelial damage, and a thrombus then forms, which is why branch vein occlusions occur at crossing points.
