ABSTRACT
PURPOSE: To describe a rare case of bilateral frosted branch angiitis with macular exudates in a 5-year-old boy presumed to be secondary to an Epstein-Barr virus (EBV) infection. OBSERVATIONS: A 5-year-old boy presented with acute onset blurring of vision in both eyes, the best corrected visual acuity was 3/60 in both eyes. The anterior segment was unremarkable, fundus showed the presence of perivascular sheathing involving the macular vessels, exudates, and subretinal fluid at the fovea (OU). Serology was positive for EBV. Swept-source optical coherence tomography angiography showed areas of flow void in the superficial and deep capillary plexus that disappeared with reduction of inflammation following treatment with intravenous, oral and topical steroids, and oral valacyclovir. CONCLUSIONS: Frosted branch angiitis can present following an EBV infection.
ABSTRACT
Purpose: To report a case of ocular dirofilariasis causing extensive chorio-retinal damage.Method: Surgical removal of the worm and identification of the same by microscopic examinationand polymerase chain reaction.Results: The worm was identified as Dirofilaria repens.Conclusion: Ocular dirofilariasis is an arthropod borne parasitic infestation affecting the subconjunctival tissue and anterior chamber. Vitreous involvement in Dirofilaria is very rare. Dirofilaria repens can cause extensive chorio-retinal damage resembling diffuse unilateralsubacute neuroretinitis.

Ocular tuberculosis (OTB) in patients with human immunodeficiency virus (HIV) commonly presents as choroidal tubercles or granuloma. We report a rare presentation of OTB with hypopyon granulomatous uveitis in a patient with HIV on highly active antiretroviral therapy (HAART). Aqueous humor polymerase chain reaction (PCR) was positive for Mycobacterium tuberculosis (MTB). Antitubercular therapy (ATT) was initiated despite which it progressed to scleral abscess and panophthalmitis. Enucleation with ball implantation was done. Histopathology revealed caseating granuloma with numerous acid-fast bacilli (AFB) and real-time PCR showed increased copies of MTB genome. After a full course of ATT, he had stable ocular and systemic condition at final follow-up.
