A 20-year-old male, presented with sudden onset decreased vision (DV) in both eyes (OU) since one week. He had a history of having been treated elsewhere for fever and cervical lymphadenopathy 15 days back with complete resolution. Best corrected visual acuity (BCVA)-OU was counting fingers close to face (CFCF). Slit lamp examination-OU revealed anterior chamber reaction-2+, vitreous cells-2+ with normal intraocular pressure (IOP). Fundus-OU revealed normal optic disc, dull foveal reflex, and multiple sinusoidal outer retinal lesions arising from the disc upto mid-periphery with intraretinal hemorrhages [Figure 1]a and [Figure 1]b. Investigations including blood smear, serology for syphilis, toxoplasmosis, human immunodeficiency virus (HIV), chest X ray and mantoux test were all normal. Other possible causes of post-fever retinitis were ruled out. Aqueous humor (AH) polymerase chain reaction (PCR) was positive for herpes simplex virus-2 (HSV-2) genome and negative for others. Fluorescein angiography (FA) showed normal choroidal and early arterial phase, perivascular leakage, and disc staining in the recirculation and late stage [Figure 2]a, [Figure 2]b, [Figure 2]c, [Figure 2]d, [Figure 2]e, [Figure 2]f. He was initiated on intravenous (IV) acyclovir 500 mg, 8th hourly for 10 days followed by oral acyclovir which was continued for 6 weeks along with tapering dose of oral prednisolone. At 1 week, lesions showed early signs of resolution [Figure 3]a and [Figure 3]b. At 3 weeks follow-up, BCVA-OU was maintained at CFCF. Anterior segment was quiet, fundus showed healed lesions with disc pallor [Figure 4]a and [Figure 4]b. Visual evoked potential revealed delayed latency suggestive of an early onset optic neuropathy. Magnetic resonance imaging (MRI) brain was unremarkable. At 3-month follow-up, ocular and systemic condition was stable. | Figure 1: (a) Color fundus montage photograph of the right eye showing distinct ribbons of sinusoidal outer retinal lines radiating outwards from the posterior pole appearing like a “White oak leaf” distinct from the retinal vessels and involving the fovea. There is loss of foveal reflex. (b) Color fundus montage photograph of the left eye showing a similar pattern and distribution of radiating white lines. There is evidence of a small segment of perivascular cuffing seen along the inferior retinal vein. There is loss of foveal reflex suggestive of macular edema

The nasal midperiphery shows a faint perivascular leakage in the recirculation phase (b). The late stage shows minimal perifoveal staining and disc staining (c). Left eye: FFA late arterio-venous (d) shows normal study. Nasal midperiphery shows a faint perivascular leakage in the recirculation phase (e). The late phase shows minimal perifoveal staining and disc staining (f)

Note – absence of residual pigmentary changes in the retinal pigment epithelium (RPE) and significant optic disc pallor.

Discussion | | |
Our patient, a young immunocompetent male with atypical HSV-2 retinitis post-fever, did not fit into any of the reported manifestations associated with non-necrotizing herpetic retinitis (NNHR) or post-fever retinitis.[1],[2],[3],[4] Serpiginoid pattern of lesions, commonly described with TB, is reported uncommonly with herpes viruses.[5] Investigations ruled out TB. Our case indicates that herpetic retinitis can present in phenotypic patterns not commonly described in literature and PCR can be diagnostic in such situations.
