Optic Nerve Head Perfusion Before and After Intravitreal Antivascular Growth Factor Injections Using Optical Coherence Tomography-based Microangiography.

Purpose: To use optical coherence tomography angiography (OCTA) to evaluate the changes in optic nerve head perfusion following intravitreal antivascular endothelial growth factor injections.

Methods: Preinjection and postinjection intraocular pressure (IOP) and OCTA images were taken of both the injected and uninjected fellow eyes.

Results: Mean preinjection IOP was 16.

Uveitis in human immunodeficiency virus-infected persons with CD4+ T-lymphocyte count over 200 cells/mL.

Background: Introduction of highly active antiretroviral therapy has altered the course of disease for persons infected with human immunodeficiency virus by elevating CD4+ T-lymphocyte levels. Changes in the spectrum of systemic diseases encountered in human immunodeficiency virus-positive individuals are reported in the general medical literature.

Design: Retrospective case series.

Enterobacter cloacae Postsurgical Endophthalmitis: Report of a Positive Outcome.

We report a positive outcome of postcataract endophthalmitis caused by Enterobacter cloacae, which has previously resulted in poor outcomes in endophthalmitis. A 67-year-old man underwent uncomplicated cataract surgery. On the morning of postoperative day (POD) #1, he had significant anterior chamber inflammation without pain, hypopyon, or vitritis but then rapidly developed hypopyon and worsening visual acuity.

Aqueous and vitreous concentrations following topical administration of 1% voriconazole in humans.

Objective: To determine the penetration of 1% voriconazole solution into the aqueous and vitreous following topical administration.

Methods: A prospective nonrandomized study of 13 patients scheduled for pars plana vitrectomy surgery. Aqueous and vitreous samples were obtained and analyzed after topical administration of 1% voriconazole every 2 hours for 24 hours before surgery.
