Retinal phlebitis complicated by punctate inner choroidopathy-like lesions: a case report

Le résumé fourni par la source

Background: Punctate inner choroidopathy (PIC) is characterized by multiple punctate lesions in the posterior pole. PIC-like lesions have been reported in association with other chorioretinal pathologies. We report a case of retinal phlebitis presenting with multiple PIC-like lesions along retinal veins. Case presentation: A 37-year-old man presented with a one-month history of metamorphopsia in his left eye. Fundus examination and optical coherence tomography revealed PIC-like lesions distributed along the retinal veins in the posterior pole, while fluorescein angiography demonstrated leakage from the retinal veins. Choroidal neovascularization (CNV) was identified near the fovea. Treatment with oral prednisolone and sub-Tenon triamcinolone acetonide injections controlled the inflammation, and intravitreal aflibercept injections managed the CNV. At the two-year follow-up, the corrected visual acuity improved to 1.2. Conclusion: The distribution of lesions along the retinal veins suggests that this case represents a presentation of PIC-like lesions secondary to retinal phlebitis.
