Purpose:This study examines treatment-based outcomes of endophthalmitis due to antivascular endothelial growth factor (anti-VEGF) intravitreal injection and its effect on subsequent management of neovascular disease.Methods:A retrospective multicenter study was conducted of 157 patients with a diagnosis of endophthalmitis following anti-VEGF intravitreal injection at 10 major ophthalmic centers.Results:The median number of injections before endophthalmitis was 10 (range, 1 to 84 injections). Initial treatment with tap and inject with or without subsequent vitrectomy trended toward smaller visual acuity changes from baseline (4 ETDRS [Early Treatment Diabetic Retinopathy Study] letter difference vs 19 ETDRS letter difference) compared with initial vitrectomy, but the difference was not statistically significant. There was no significant change in medication choice among injections after endophthalmitis. There was a statistically significant shift away from regular interval (1- to 2-month) injections and a shift toward treat-and-extend and as-needed injection algorithms.Conclusions:The visual outcomes were not significantly different between patients who initially underwent tap and injection of antibiotics and those who underwent vitrectomy. There was no significant change in medication choice before and after endophthalmitis but there was a shift toward lower-frequency injection algorithms after postintravitreal injection endophthalmitis compared with prior.

Purpose: To explore the safety, comfort, and feasibility of topical anesthesia in 27-gauge pars plana vitrectomy surgery. Methods: A prospective, observational case series of 37 nonconsecutive patients undergoing 3-port, 27-gauge pars plana vitrectomy under topical anesthesia with lid block from July 2016 to March 2017 with a single surgeon was performed. Topical anesthesia was achieved with proparacaine 0.5% drops and 2% lidocaine gel. Surgery was performed for select indications with carefully selected patients amenable to topical anesthesia. Patients were queried and observed to identify the most painful steps of the case and to rate their intraoperative and postoperative pain scores on a 1- to 10-point pain scale. Results: The mean intraoperative pain score was 2.1 with the most painful steps rated as scleral depression (37.8%), trocar/cannula insertion (24.3%), and conjunctival coaptation (24.3%). When correlating the overall intraoperative pain score with the self-identified most painful step, the mean pain scores were highest for endolaser (2.6), scleral depression (2.1), conjunctival coaptation (2.1), and trocar/cannula insertion (1.6). Supplemental intravenous anesthesia was requested once by the surgeon in 54% of the cases. No rescue with local infiltrative anesthesia was required. The mean pain scores were 0.7 and 0 at postoperative day 1 and week 1. No intraoperative or postoperative complications were encountered. Conclusions: Topical anesthesia for 27-gauge pars plana vitrectomy is a safe and feasible anesthesia option for carefully selected patients for certain surgical indications.

Purpose: To describe 2 techniques facilitating the potentially challenging removal of the anterior hyaloid during phakic pars plana vitrectomy. Methods: Observational surgical series describing the 2 techniques. The hydrodissection technique applies an injection of balanced salt solution into the anterior chamber to displace the anterior hyaloid posteriorly for facile removal. The bubble technique is a novel method that utilizes air bubbles to visualize the anterior vitreous, allowing closer placement of the vitrectomy cutter to facilitate anterior hyaloid removal. Results: Both techniques were successful for the safe, efficient removal of the anterior vitreous. Conclusion: Removal of the anterior vitreous in a phakic patient is a difficult maneuver which may lead to potential damage to the lens. The hydrodissection and bubble techniques may be used to efficiently and safely remove the anterior vitreous.
