Not true regarding retinal anatomy
Layer in contact with vitreous is internal limiting membrane Foveal Avascular Zone- * No blood vessels in this zone * Geometric centre is centre of macula & Fixation point * Impoant landmark in FA * Ora serrata > Foveola: Thinnest pa of retina * Posterior Pole: Macula + Optic nerve head * Optic disc approx: 1.75 mm (H), 1.90 mm (V) * Macula: 5.5 mm (Temporal to optic disc) * Fovea - Centralis : Central depressed pa of Macula, 1.5 mm Foveola - 0.35 mm. * Thinnest pa of retina after ora serrata. * Contains no rods, only cone are there that are covered by internal limiting membrane * The axons are arranged horizontally and are called Henles layer
Most of the layers of retina are absent at foveala
The layer of retina in contact with vitreous is retinal pigment epithelium
Posterior pole consists of optic nerve head and macula
Fovea has a zone where there is no blood supply
