Amalric triangular sign in a case of central retinal artery occlusion combined with posterior ciliary artery occlusion – Case report

American Journal of Ophthalmology Case Reports, 2018
Purpose: Amalric triangular sign is a rare phenomenon indicating choroidal ischemia. In this study, we reported a typical Amalric triangular sign in a case of central retinal artery occlusion (CRAO) combined with posterior ciliary artery (PCA) occlusion.

Retinal arterial collapse pressure in eyes with retinal arterial occlusive diseases [PDF]

British Journal of Ophthalmology, 2004
Retinal arterial occlusions may be primarily or secondarily associated with low retinal arterial pressure. Based on previous ophthalmodynamometric studies1–6 the purpose of the present study is to estimate the retinal vessel pressure in patients with central retinal artery or branch retinal artery occlusions and patients with amaurosis fugax.
