A 27-year-old woman presented with pain, redness, and diminution of vision in the left eye (LE) for two days. On presentation, the best-corrected visual acuity (BCVA) was 20/20 in the right eye (RE) and 20/125 in LE. Intraocular pressure (IOP) was 14 mmHg and 26 mmHg in RE and LE (on anti-glaucoma medications), respectively. On examination, RE was unremarkable, and LE showed ciliary congestion, shallow anterior chamber, keratic precipitates, grade-2 cells, and a mid-dilated pupil. Gonioscopy revealed open angles in RE and grade-1 narrow angles in LE. The fundus examination of LE showed a cup-disc ratio of 0.9:1 with multiple serous retinal detachments in the posterior pole Fig. 1. Fluorescein angiography, ultrasonography, and optical coherence tomography findings Fig. 2 were suggestive of probable Vogt-Koyanagi-Harada disease (VKH). The patient was started on systemic and topical steroids with cycloplegics. LE BCVA improved to 20/80, IOP reduced to 15 mmHg after 3 days of treatment. At a 2-weeks follow-up, LE BCVA was 20/32, IOP was 10 mmHg, the anterior chamber was deep and quiet, and fundus showed complete resolution of serous detachments Fig. 3. A visual field test revealed a reproducible superior arcuate scotoma in LE suggestive of nonarteritic anterior ischemic optic neuropathy (AION). On completion of the course of steroids, immunosuppression therapy was initiated. At one and half year follow-up, LE BCVA was 20/32 and the visual field defect remained stable. Her right eye remained uninvolved over the entire follow-up period.Figure 1: Fundus photographs of (a) uninvolved right eye and (b) left eye demonstrating a clear vitreous, a large and deep optic cup (cup disc ratio of 0.9:1) with multiple serous retinal detachments in the posterior poleFigure 2: (a) Fundus fluorescein angiography of the left eye showing multifocal points of pinpoint leakage in the early venous phase and (b) pooling within the subretinal fluid in the late phase.

It could be attributed to AION, which though rare, has been reported in patients less than 40 years of age with no vasculopathic risk factors.3 Eyes with AION may not always show altitudinal visual field defects but also a variety of visual field defects depending upon the involvement of the branches of the posterior ciliary artery. Association of VKH with AION is known but rare, all of which manifested in the fifth and sixth decades of life.45 Our case shows a unique presentation of VKH associated with AION as AACG in a young woman.
