To retrospectively analyze clinical outcomes of patients with "treatment-resistant" neovascular age-related macular degeneration or diabetic macular edema who were switched to intravitreal faricimab injections (IFIs) using a "real-world" treat-and-extend (TAE) protocol. Seventy-one eyes from 62 patients receiving antivascular endothelial growth factor injections were evaluated before and after switching to IFI. Demographic and clinical data were collected.

Purpose: This work evaluates demographic and socioeconomic predictors of delayed care for rhegmatogenous retinal detachments (RRDs) during the spring 2020 COVID-19 shutdown in a US hot spot.

Methods: This multicenter, retrospective, case-control study took place in 3 academic vitreoretinal practices in metropolitan Boston. Consecutive patients treated for RRD during the COVID-19 state of emergency were compared with patients treated during the same period in 2018 and 2019.

Purpose: To evaluate the functional and anatomic outcomes, as well as cost-effectiveness, of the timing of conversion to intravitreal aflibercept (IVA) in patients with treatment-resistant diabetic macular edema (DME).

Methods: Thirty consecutive eyes (25 patients) were identified that were treated with ≥3 intravitreal bevacizumab (IVB) and/or ranibizumab (IVR) injections prior to treatment with ≥3 IVA injections. Eyes that received ≤6 IVB and/or IVR injections (early-switch) were compared to those that received ≥7 injections (late-switch) prior to conversion to IVA.

Purpose: To compare the change in anterior chamber flare after intravitreal injection of the anti-vascular endothelial growth factor agents bevacizumab, aflibercept, and ranibizumab.

Methods: Sixty-one eyes of 53 patients underwent intravitreal injection with anti-vascular endothelial growth factor medications for exudative age-related macular degeneration, diabetic macular edema, or retinal vein occlusion. There were a total of 26 eyes injected with bevacizumab, 14 eyes injected with aflibercept, and 21 eyes injected with ranibizumab.

Purpose: To compare the effectiveness of four different anesthetic methods for intravitreal injection.

Methods: Twenty-four patients each received four intravitreal injections using each of four types of anesthesia (proparacaine, tetracaine, lidocaine pledget, and subconjunctival injection of lidocaine) in a prospective, masked, randomized block design. Pain was graded by the patient on a 0 to 10 scale for both the anesthesia and the injection.

Purpose: To determine if Preferential Hyperacuity Perimetry (PHP) testing can detect the presence of retinal toxicity due to hydroxychloroquine (HCQ) or chloroquine administration.

Methods: Fifteen patients were divided into three groups. Five patients had confirmed HCQ or chloroquine toxicity, five patients had suspected HCQ toxicity, and five patients had history of long-term use of HCQ or chloroquine but no evidence of toxicity.

Purpose: To describe the anatomic and visual outcomes of patients in whom noninfectious endophthalmitis developed after injection of intravitreal triamcinolone acetonide.

Design: Retrospective case series.

Methods: Ophthalmologic evaluations of patients in whom noninfectious endophthalmitis developed after intravitreal triamcinolone took place on the day of injection, at the time of presentation of noninfectious endophthalmitis, at the time of clearance of inflammation, and on follow-up examination.

Background And Objective: To report a case series of patients with profound choroidal hypoperfusion on fluorescein angiography following combined photodynamic therapy (PDT) and intravitreal triamcinolone acetonide (IVT) for age-related macular degeneration.

Patients And Methods: A retrospective chart review was performed of all 108 patients (155 treatments) who had combined PDT/IVT between January 2002 and December 2004 at the institution.

Results: Fifteen patients were identified with "profound choroidal hypoperfusion.
