Retinal Arteriolar Variation
Oct 31 2024 by AVIK DEY SARKAR, MS, FVRS, FAICO(VR)
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.

Combined Hamartoma of the Retina and Retinal Pigment Epithelium
Apr 26 2020 by Dipak Nag, MBBS, FCPS, MSc, FRF
A 28-year-old female presented with a deeply pigmented gray- brown, elevated lesion extending from the temporal side of the disc to the macula (OU). Remarkable retinal vasculature with straightening of the distal vessels and dilatation as well as tortuousity of the peri-lesional vessels. The vitreoretinal interface shows gliosis and epi-retinal membrane (ERM) formation.
