OPTIC NERVE COLOBOMA

This 19YO male has bilateral optic nerve coloboma with optic pit maculopathy in his left eye. On initial presentation, vision was 20/70, which decreased to 20/200 at 3-month follow-up. The extent of the macular schisis/fluid dramatically enlarged, accounting for the drop in vision. Optos fundus autofluorescence (FAF) showed variable hyper-FAF along the temporal edge of… Read More


HARADA DISEASE

This 63YO female presented with a 3-week history of bilateral painful vision loss. Vision was 20/400 OD and 20/100 OS. She had bilateral granulomatous anterior uveitis with a clear vitreous OU. Both nerves were swollen, and irregular chorioretinal folds were noted throughout each macula. Extensive incidental peripheral drusen were also present. Triton swept-source OCT scanning… Read More


PIGMENT EPITHELIAL DETACHMENT (PED)

This 57YO female presented with counting-finger vision from a large RPE detachment (PED). The PED was located in the temporal macula, with a smaller notch of irregular RPE elevation more centrally. Triton swept-source OCT shows a shallow PED at the notch overlying Bruch’s membrane. Optos fluorescein angiography shows late uneven filling of the PED and… Read More


USHER SYNDROME

This 26YO female presented with progressive bilateral vision loss and photophobia. Vision was 20/60 OD and 20/200 OS. She had moderate hearing loss since birth, and denied any family history of eye disease. Ultra-wide-field imaging reveals areas of nasal mid-peripheral bone spicules (intraretinal pigment migration) and ‘beaten-bronze’ macular atrophy. There is a ring of hyper-autofluorescence… Read More


CRVO

This 74YO female has large optic nerve collaterals from an old non-ischemic central retinal vein occlusion. Vision was 20/30. Learning Points: Collateral vessels are dilated, pre-existing vessels that bypass an occlusion. These are most commonly seen in the posterior pole, following retinal venous occlusions, often on the optic disc. In collateral vessels, the endothelial tight… Read More


OCULAR HISTOPLASMOSIS

This 44YO male presented with a symptomatic macular neovascularization (MNV) from ocular histoplasmosis. Vision was 20/40. Subretinal blood surrounds the MNV in the temporal macula. On OCT, the MNV is located above the RPE, indicating a type 2 lesion. Some retinal thickening is noted above the MNV. The blood and fluid resolved completely following several… Read More


RELENTLESS PLACOID CHORIORETINITIS

This 12YO boy was referred for asymptomatic retinal changes. Vision was counting fingers OD and 20/25 OS. Optos imaging shows patchy inactive chorioretinal scarring extending from each macula to the mid-periphery, especially confluent in the right macula. There is variable hyper- and hypo-autofluorescence, and fluorescein angiography shows areas of staining. Triton swept-source OCT shows variable… Read More


RHEGMATOGENOUS RETINAL DETACHMENT

This 77YO patient presented with 20/200 vision from a superior macula-off retinal detachment. Optos imaging beautifully captures the detachment that was caused by several superior retinal tears. Learning Points: The normal neurosensory retina remains attached to the RPE due to numerous physiologic mechanisms, including the inner (retinal vascular endothelium) and outer (tight junctions at the… Read More


RETINOCYTOMA

This 57YO male presented with a retinocytoma without any history of retinoblastoma (RB) or treatment for RB. Clinically, retinocytomas can resemble astrocytic hamartomas. However, retinocytomas often have underlying RPE changes and chorioretinal scarring, which are not present in astrocytic hamartomas. Learning Points: Retinocytomas are fleshy, opalescent, benign tumors that are thought to spontaneously regress in… Read More


CHOROIDAL GRANULOMA

This 22YO female presented with 20/400 vision from a macular neovascularization (MNV) associated with a choroidal granuloma. The Triton image shows a focal yellow-white nodular subretinal lesion with adjacent subretinal pigment and blood along its foveal edge. Swept-source OCT through the MNV shows the hyperreflective MNV above Bruch’s membrane. Fluorescein angiography shows leakage from the… Read More
