Clinical and multimodal imaging characteristics of eyes with Vogt-Koyanagi-Harada disease: An Egyptian experience.

Background: Vogt-Koyanagi-Harada (VKH) disease is a vision-threatening inflammatory disorder that is challenging in diagnosis and management.

Methods: Retrospective, record-based analysis of 54 eyes belonging to 27 adult patients that fulfilled the revised diagnostic criteria for VKH between January 2018 and January 2021. Demographic, clinical, and imaging data on presentation and during follow-up visits were collected for each patient.

Bilateral macular retinitis in patients with presumed rift valley fever from Sudan: A case series.

Background: Epidemic retinitis occurs seasonally following febrile infections in endemic regions. Rift valley fever (RVF) is endemic to Sudan, with a recent outbreak starting in 2019.

Methods: Retrospective case series of 3 patients travelling from Sudan with post-febrile retinitis, and with a history and clinical picture suggestive of RVF retinitis.

Bilateral Simultaneous Anterior Ischemic Optic Neuropathy following Total Knee Arthroplasty with Epidural Block.

Ischemic optic neuropathy (ION) resulting in perioperative vision loss (POVL) is a rare occurrence following nonocular procedures. Bilateral simultaneous anterior ION (AION) is even rarer, and no cases have been reported after central neuraxial block. We report a case of bilateral simultaneous AION, confirmed by multimodal imaging, in a 66-year-old male patient who underwent total knee arthroplasty under epidural anesthesia in which episodes of hypotension-one intraoperatively and one late postoperatively-had occurred.
