Primary Hyperoxaluria and Oxalosis
Oct 10 2015 by Hamid Ahmadieh, MD
Color fundus photograph of the left 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.

Lignocaine Retinal Toxicity
Aug 18 2015 by Mallika Goyal, MD
Right eye fundus of a 70-year-old male 3 weeks after inadvertent globe penetration with peribulbar anaesthesia needle and intraocular injection of lignocaine. There is a thick taut epimacular membrane with severely increased central retinal thickness. Fluorescein angiography revealed an occluded retinal arteriole at the macula indicating macular ischaemia underlying the 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.

Idiopathic retinal vasculitis, aneurysms and neuroretinitis
Apr 24 2022 by Aniruddha K Agarwal, MD
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.

Ruptured Retinal Artery Macroaneurysm
Jun 18 2024 by KANWALJEET HARJOT MADAN, M.S. (Ophthalmology), FAICO (Vitreous - Retina)
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.

Bilateral Calcific Retina Arteriolar Occlusions in a Patient with Metastatic Ovarian Carcinoma
Dec 10 2020 by McGill University Health Centre
47-year-old female with cough and fever. Imaging showed a right pulmonary infiltrate. Transbronchial needle biopsy revealed lymphangitic spread of papillary adenocarcinoma with psammoma bodies. MRI of thyroid, CT of abdomen and pelvis were negative. gynecologic evaluation negative at that time. The patient had bilateral floaters, VA: 20/40 OD and 20/20 OS. Fundus examination showed retinal arteriolar sheathing and a flat choroidal lesion OS and vitritis OD. Fluorescein angiogram showed staining of left superior temporal retinal arterioles and bilateral midperipheral patchy hyperfluorescence at RPE The patient vision in the OD deteriorated to 20/400, and in the OS 20/50. Four months later a new choroidal lesion was diagnosed OS. An abdominal mass consistent with a cystadenoma of the ovary was diagnosed. After a year patient developed systemic metastasis. Autopsy: Metastatic adenocarcinoma to the lung, both adrenals, para-aortic lymph nodes, left hip, right breast, occipital skin, serosal surface of liver, pituitary. In almost all metastatic lesions psammoma bodies were found. Presumptive diagnosis is a primary tumor of the ovary.

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.

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.
