Purpose: Despite its off-label status, intravitreal bevacizumab is the most commonly used intraocular anti-vascular endothelial growth factor agent. Regulation of compounding pharmacies has recently increased to make compounded pharmaceuticals safer. Despite these changes, a marked increase in symptomatic, large silicone oil droplets following intravitreal bevacizumab injections was noticed.

Purpose: To evaluate the systemic pharmacokinetics (PKs) of aflibercept, bevacizumab, and ranibizumab in patients with neovascular age-related macular degeneration (AMD), diabetic macular edema (DME), or retinal vein occlusion (RVO).

Methods: Prospective, open-label, nonrandomized clinical trial of patients with AMD, DME, or RVO who were antivascular endothelial growth factor (VEGF) naïve or had not received anti-VEGF for ≥4 months. Patients received 3 monthly intravitreal injections of aflibercept 2.

Purpose: To assess the posterior vitreous release rates following a single, office-based intravitreal injection of expansile gas in treating vitreomacular traction.

Methods: Thirty eyes of 29 consecutive patients with symptomatic vitreomacular traction received a single, office-based intravitreal injection of up to 0.3 mL of 100% perfluoropropane (C3F8).

Purpose: To report initial experience with intravitreal ocriplasmin (IVO) and to describe outer retina reflectivity changes observed on spectral domain optical coherence tomography (SD-OCT) after IVO injection in patients with vitreomacular traction (VMT) with or without macular holes (MHs).

Methods: A consecutive retrospective review of patients with VMT and MH who were treated with IVO was performed. Patients underwent complete ophthalmic evaluation, including nonstandardized Snellen visual acuity testing, and SD-OCT at baseline and follow-up visits.

Purpose: To present the long-term follow-up of a patient injected with intravitreal ocriplasmin who experienced severe acute post-intravitreal ocriplasmin complications.

Methods: Case report.

Results: A 68-year-old man with vitreomacular traction was treated with intravitreal ocriplasmin.

Background: Data comparing systemic exposure and systemic vascular endothelial growth factor (VEGF) suppression of ranibizumab, bevacizumab and aflibercept following intravitreal injection are lacking.

Methods: Fifty-six patients with wet age-related macular degeneration received intravitreal ranibizumab (0.5 mg), bevacizumab (1.

Purpose: To evaluate the safety and efficacy of intravitreal ranibizumab for macular edema secondary to central retinal vein occlusion.

Methods: Patients with macular edema secondary to perfused central retinal vein occlusion were enrolled in this ongoing, prospective, open-label study. Treatment was initiated with monthly intravitreal ranibizumab for 3 months.

Purpose: Assessment of biological effect, visual acuity changes, and safety of intravitreal (IVT) ranibizumab in patients with macular edema associated with perfused central retinal vein occlusion (CRVO).

Design: Ongoing, prospective, open-label, single-center, uncontrolled study.

Participants: Ten adult patients with macular edema associated with perfused CRVO.

Background: To determine the maximum tolerated dose (MTD) of enoxaparin, a low molecular weight heparin (LMWH) was used during repeat vitrectomy for rhegmatogenous retinal detachment with proliferative vitreoretinopathy (PVR) and severe diabetic retinopathy.

Methods: From 25 patients, 29 eyes undergoing repeat vitrectomy for PVR (CP3 or greater) or severe diabetic retinopathy were included in the study. Patients had previously undergone an average of 2.
