Color montage photograph of the right eye on presentation showing vascular tortuosity, vessel sheathing, white-centered intra-retinal hemorrhages, blurring of the optic disk margins, and peripapillary edema. These findings appeared consistent with a CRVO.

Visual acuity declined to 20/200 in the right eye, and fundus examination showed worsening of the baseline retinal findings (Figure 1).
Fluorescein angiogram (FA) at presentation of the right eye. A. Early and (B) late frames. C. A montage FA. There is delayed filling of the venules, venous congestion, and phlebitis consistent with a nonischemic CRVO.

Fluorescein angiography confirmed the diagnosis of a nonischemic CRVO (Figure 2).
Time-domain optical coherence tomography at presentation of the right eye. A. A temporal-to-nasal scan through the fovea shows no central cystoid macular edema. B. Retinal thickness map shows peripapillary retinal thickening.

Optical coherence tomography showed lack of cystoid macular edema (Figure 3).
A. Color photograph of the right eye 1 week after presentation shows retinal whitening, diffuse intraretinal hemorrhages, macular edema, and severe vascular tortuosity, congestion, and sheathing. B-D. Fluorescein angiogram reveals markedly delayed and incomplete retinal and choroidal vascular filling with severe ischemia, consistent with worsening of the CRVO and the development of an ophthalmic artery occlusion.

Examination showed worsening of the CRVO and the development of an ophthalmic artery occlusion (Figure 4).
Spectral domain optical coherence tomography through the fovea of the right eye at 1 week after presentation shows diffuse retinal edema and disturbance of all retinal layers.

An optical coherence tomography scan showed diffuse macular edema and retinal thickening (Figure 5).
