OFFICIAL HORV CASE REPORT |
1. Survey Introduction
The American Society of Retina Specialists (ASRS) and the American Society of Cataract and Refractive Surgery (ASCRS) have formed a task force to investigate hemorrhagic occlusive retinal vasculitis (HORV), which is a rare complication of any intraocular procedure (usually cataract surgery) characterized by vision loss occurring 1 to 26 days after an unremarkable post-operative day 1 examination.
HORV is associated with severe retinal hemorrhage and ischemia. The clinical appearance can be mistaken for acute retinal necrosis. Neovascularization of the anterior segment is a common complication. Severe visual loss (20/200 or worse) is common. All definitive cases that have been reported to date have received intraocular vancomycin (intracameral bolus, infusion bottle, or intravitreal).
You have indicated that you have helped manage a case of HORV. It is very important that we learn as much about each rare case as possible so that we can determine the cause and prevent further cases. Please complete the thorough questionnaire below to the best of your ability. Answer as many questions as you can. A member of the HORV Task Force may follow up with you if further questions arise. All information will be kept de-identified and confidential.
