In the von Szily mouse model, intracameral inoculation of herpes simplex virus type-1 (HSV-1) results in inflammation of the ipsilateral anterior segment with relative chorioretinal sparing and destructive contralateral chorioretinitis. We studied the effect of the systemic antiviral agent acyclovir (ACV) and anti-HSV-1 antibody therapy in this model. Contralateral chorioretinitis developed in none of the 18 mice receiving ACV from post-inoculation day (pid) 1 (p < 0.0001), in 6 of 10 (60%) mice when treatment was delayed until pid 7 (p = 0.40) and in 14 of 18 (77%) controls. Contralateral disease developed in 8 of 16 (50%) mice that received anti-HSV-1 antibody from pid 1 (p = 0.02), in 13 of 16 (81%) treated from pid 5 (p = 0.64), in 7 of 8 (87.5%) treated from pid 7 (p = 1.0) and in 17 of 20 (85%) controls. We conclude that early treatment with ACV or anti-HSV-1 antibody reduces the incidence of contralateral chorioretinitis in mice.

Purpose: To illustrate the characteristics of perforating scleral vessels in macular regions between mCNV eyes and contralateral eyes in unilateral mCNV patients.
Methods: This was a retrospective study that included patients with unilateral naive mCNV. The study aimed to identify and analyze the distribution of perforating scleral vessels (PSVs) in the macular region of mCNV eyes and contralateral eyes.

Purpose: To report on cases of unilateral perimacular atrophy after treatment with voretigene neparvovec-rzyl, in the setting of previous contralateral eye treatment with a different viral vector.
Design: Single-center, retrospective chart review.
Methods: In this case series, four patients between the ages of six and 11 years old with RPE65-related retinopathy were treated unilaterally with rAAV2-CB-hRPE65 as part of a gene augmentation clinical trial (NCT00749957).

Background: We describe a case of relentless placoid chorioretinitis (RPC) that progressed despite administration of peribulbar and systemic corticosteroids, and was resolved by systemic combined with intravitreal methotrexate.
Case Summary: A 16-year-old male reported painless blurred vision and a temporal scotoma in his right eye for one week. Due to widespread distribution and continuous enlargement, multimodal imaging of the lesions led to the diagnosis of RPC.
