Purpose: To demonstrate the response of a juxtapapillary retinal hemangioblastoma (JRH) to belzutifan in a patient with Von-Hippel-Lindau syndrome (VHL).

Methods: This case report includes fundus photography and optical coherence tomography to compare a juxtapapillary retinal hemangioblastoma (JRH) before and 24 months after treatment with belzutifan.

Results: An 18-year-old woman with VHL was diagnosed with a juxtapapillary retinal hemangioblastoma (JRH) at age 13.

Objective: To describe the frequency and predictors of local treatment failure and enucleation after iodine 125 (I) brachytherapy in patients with choroidal melanoma treated and followed up in a large randomized clinical trial.

Design: Prospective, noncomparative, interventional case series within a randomized, multicenter clinical trial.

Participants: Patients enrolled in the Collaborative Ocular Melanoma Study (COMS) trial of enucleation versus brachytherapy between February 1987 and July 1998; tumors measured 2.

Purpose: To determine the feasibility and safety of bilateral simultaneous vitreoretinal surgery in pediatric patients.

Design: International, multicenter, interventional, retrospective case series.

Participants: Patients 17 years of age or younger from 24 centers worldwide who underwent immediate sequential bilateral vitreoretinal surgery (ISBVS)-defined as vitrectomy, scleral buckle, or lensectomy using the vitreous cutter-performed in both eyes sequentially during the same anesthesia session.
