Incising the meshwork during goniotomy creates direct communication between which two spaces?
A fine goniotomy knife or needle incises the trabecular meshwork along part of the angle's circumference, creating direct communication between the anterior chamber and Schlemm's canal.
Goniotomy: Opening the Angle From Inside for Congenital Glaucoma
How might a low cerebrospinal fluid pressure around the optic nerve contribute to normal-tension glaucoma?
Low cerebrospinal fluid pressure in the space around the nerve creates a larger-than-usual gradient across the lamina cribrosa even when intraocular pressure itself is normal.
Normal-Tension Glaucoma: Damage Without the High Pressure
What is the fundamental limitation of a capsular tension ring in eyes with zonular loss?
The ring reinforces and redistributes the zonular support that remains; where support is absent entirely it cannot substitute for it, so very extensive loss may still need scleral fixation.
Capsular Tension Rings: A Simple Device That Rescues Difficult Cataract Cases
Within what interval is canalicular laceration repair ideally performed?
Repair is ideally carried out within 24 to 48 hours of injury, before the cut edges retract and become harder to find and appose.
Canalicular Laceration Repair: Finding the Cut End Before It Scars Shut
In necrotizing scleritis, avascular patches of sclera are an ominous sign of what?
Avascular patches of sclera are described as a particularly ominous sign because they reflect vascular occlusion within the inflamed tissue.
Necrotizing Scleritis: Why Immunosuppression, Not Just Steroids, Is the Treatment
How does the thick sclera of nanophthalmos predispose the eye to uveal effusion?
The abnormally thick sclera restricts normal transscleral fluid outflow from the choroid and the vortex veins, which is what predisposes to effusion.
Nanophthalmos: The Small Eye With a Thick, Risky Sclera
Which consequence may follow a diffuse choroidal haemangioma in Sturge-Weber syndrome?
A diffuse choroidal haemangioma may cause hyperopia, serous retinal detachment, cystoid macular oedema and retinal degeneration, and subtle lesions may need ultrasound, OCT or ICG angiography.
Sturge-Weber Syndrome: Glaucoma, Choroidal Hemangioma and the Surgical Traps
A boat-shaped haemorrhage with a flat upper border and a fluid level lies in which plane?
Preretinal or subhyaloid blood collects between the internal limiting membrane and the posterior hyaloid, forming a boat-shaped or crescent haemorrhage with a flat upper border.
