Right eye Fluorescein and Indocyanine green angiography of a 42 year old male in case of Choroidal hemangioma. Choroidal hemangioma have a unique pattern of circulation where the large blood vessels produce a “COARSE VASCULAR PATTERN.” Fluorescein angiography of circumscribed choroidal hemangiomas typically reveals very early hyperfluorescence of larger-caliber choroidal blood vessels either before or simultaneously with the initial filling of the retinal arterioles. Indocyanine green angiography typically shows filling of the intralesional vascular channels, intense hypercyanescence of the lesion by the intermediate frames (peaks around 3-4 minutes) and late washout of the central portion of the lesion.

A 43-year-old hypertensive patient, diagnosed with Non-Ischemic Central retinal vein Occlusion in OS, presented with a striking anatomical variation in retinal vasculature. The inferior first-order retinal arteriole after initiating from the optic disc bifurcates, before reaching the fovea, and the superior branch after crossing the midline forms the superior arcade afterwards and produces dichotomous branching as usual. This defies basic anatomical considerations for retinal vasculature as they never cross the midline, also known as the watershed line for retinal vessels.1,2 References: 1. May CA, Rutkowski P.

Ruptured retinal arterial macro-aneurysm found in a 56 YO female patient with history of untreated hypertension. Round or fusiform dilation of a retinal arteriole is usually seen within a third degree branch of one of the four main arcade arteries. Most common location for a symptomatic macroaneurysm is from a branch of the superotemporal arcade.

This is a fundus photo depicting ruptured Retinal Artery Macroaneurysm (RAM) in the left eye of a 63 years old female. RAM is an acquired saccular or fusiform dilatation of the retinal arterioles that usually occur within the first three orders of bifurcation. The Superotemporal artery is the most common location. RAM may be asymptomatic or cause a number of complications such as macular edema, serous macular detachment, and hemorrhages.

Ultra-wide field fundus fluorescein angiography (FFA) of the left eye from an asymptomatic, healthy 33-year-old woman who was referred to the retina clinic from a refractive surgery unit due to the presence of vascular anomalies and hard exudates in both eyes. FFA revealed the characteristic sacular aneurysms at the bifurcation of retinal arterioles in the posterior pole, together with microvascular anomalies and capillary closure peripherally.

Senile macular degeneration with disciform scar. A retinal arteriole (as­terisk) extends into the subretinal component of the scar, through a break in the thick­ened and detached inner layer of Bruch's membrane, and then into the vascularized intra-Bruch's-membrane component of the scar. Study of serial sections disclosed this retinal vessel to anastomose with the choroidal vessel (arrow) which extends through a branch in Bruch's membrane.

Cholesterol emboli to retina and choroid. There is a large microinfarction of the nerve fiber layer (arrows). A cholesterol embolus is lodged in a retinal arteriole (upper right) proximal to the microinfarction. Cholesterol emboli were also found in the choroid, and in one (lower right) erythrocytes (arrow) could be seen in the periphery as they were presumably going around the embolus.

Retinal arterial macroaneurysm. A ring of retinal exudate partially sur­rounds the macroaneurysm (upper left), which is more clearly delineated by fluorescein (upper right). The retinal arteriole is greatly dilated, and the stain for elastic tissue shows a localized area of disruption and loss of the internal elastic membrane (arrow). The surrounding retina is thickened by edema and some hemorrhage. The ectatic area of the vessel wall is greatly thickened by the accumulation of a laminated fibrinous ma­terial.

Color fundus photograph of the right eye of a 55-year-old woman with primary hyperoxaluria and oxalosis leading to intraretinal and subretinal deposition of calcium oxalate crystals . In addition, deposition of these crystals in the retinal vessels has led to the occlusion of retinal arterioles and venules leading to multiple cotton wools and dot and blot retinal hemorrhages.
