This 72YO male presented with a macula-off rhegmatogenous retinal detachment (RRD). Optos imaging gives the illusion of four breaks, although in actuality, there are only two tractional tears. The hydrated outer retinal folds are best visualized on green channel imaging. Vision was 20/60, and the retina was successfully reattached with emergent pars plana vitrectomy.

This 66YO male has mild lifelong decreased vision in his left eye. Vision was 20/70. Triton imaging of the optic nerve coloboma shows optic nerve pits temporally and nasally, as well as a more inferior choroidal coloboma. Swept-source OCT dramatically reveals the pits. We are following him yearly. Learning Points: Both optic nerve and choroidal… Read More

This 16YO male presented with asymptomatic, unilateral disseminated patches of choroidal melanocytosis. There were no anterior segment or skin abnormalities. Learning Points: Choroidal melanocytosis is part of the oculodermal spectrum, which occasionally includes pigmentation of the globe or periocular skin (Nevus of Ota, melanosis oculi). There are increased dendritic melanocytes in the affected tissues following… Read More

This 63YO male patient has a full-thickness macular hole (MH) with 20/80 vision. The hole is not well imaged in the color photograph. OCT B-scan shows a small MH without traction. The en face image beautifully depicts a unique perspective on an otherwise unremarkable case. The macular hole is hyporeflective centrally with multiple hyporeflective cystoid… Read More

This is a great case of active toxoplasmosis. The OCT B-scans show full-thickness retinitis with a volcanic-like eruption of the inflammatory process extending into the attached vitreous. Learning Points: Toxoplasmosis, the most common cause of infectious chorioretinitis in humans, is caused by the protozoan parasite, Toxoplasma gondii. It is most commonly transmitted through infected felines… Read More

This 61YO male presented with these asymptomatic blood vessels extending superiorly from the right nerve. Vision was 20/25 OU, and the left eye was normal. The abnormal vessels emanate from a cilioretinal artery, extend superiorly into and then above the macula, then arch nasally and descend. Note that it crosses a vein, confirming that it… Read More

This is a 3YO female with a history of bilateral retinoblastoma and prior enucleation of the right eye. It is a follow-up of a previously posted case (11/7/21). Optos imaging of the left eye shows an active retinoblastoma with complete regression following 6 months of treatment, which included intra-arterial chemotherapy and cryotherapy. Learning Points: Small… Read More

This 80YO male presented with an acute branch retinal artery occlusion (BRAO) and 20/25 vision. Triton color imaging shows an opaque retina in the superior macula. Swept-source OCT shows a thickened, hyperreflective inner retina with posterior shadowing due to decreased light transmittance through the opacified inner retinal layers. There are no emboli. This patient had acute… Read More

This patient originally presented in 2018 with vision of 20/40 OD and 20/50 OS. Areas of AMD-related macular atrophy (MA) skirted each macular center. Four years later, vision had decreased to 20/100 OU due to progressive atrophy. Comparing the two images from 2018 to 2022, there is a bilateral linear enlargement for all margins of… Read More

This 31YO male was referred for relatively asymptomatic central macular pigmentary changes. He gave a long history of twice-daily sun gazing, which always caused a very pleasurable sneezing episode. Vision was 20/30 OD and 20/40 OS. Triton color imaging shows tiny foveal pigment loss. Swept-source OCT shows bilateral ellipsoid zone and outer segment defects. We… Read More
