Nonmydriatic Ultra-Widefield Fundus Photography in a Hematology Clinic Shows Utility for Screening of Sickle Cell Retinopathy.

PURPOSE: To determine the feasibility and accuracy of nonmydriatic ultra-widefield (UWF) fundus photographs taken in a hematology clinic setting for screening of sickle cell retinopathy (SCR) DESIGN: Prospective cohort study. METHODS: This single-site study took place at the Johns Hopkins Sickle Cell Center for Adults and the Wilmer Eye Institute. The study population was 90 eyes of 46 consecutive adults with sickle cell disease (SCD). Bilateral nonmydriatic fundus photos taken by clinic personnel during the participants' routine hematology appointment were graded by 2 masked retina specialists at the Wilmer Eye Institute for the presence of nonproliferative SCR (NPSR) and proliferative sickle retinopathy (PSR). A third retina specialist adjudicated in cases of grader disagreement. All participants underwent the standard dilated fundus examination (DFE) within 2 years of acquisition of UWF photographs. The main outcome measure was the sensitivity and specificity of nonmydriatic UWF images for the detection of NPSR and PSR RESULTS: PSR was noted in 19 of 90 eyes that underwent DFE and in 9 of 67 gradable UWF images. Interrater agreement between the 2 graders was moderate, with κ = 0.65 (range 0.43-0.87) for PSR. For gradable UWF photos, the sensitivity and specificity of detecting SCR using the nonmydriatic photos compared with the DFE were 85.2% and 62.5% for NPSR, respectively, and 69.2% and 100% for detection of PSR, respectively. One participant required ophthalmic therapy in both eyes for active sea-fan neovascularization. CONCLUSIONS: UWF imaging shows utility in screening for SCR and may help identify patients with PSR who require a DFE and who may benefit from treatment.

Implementation of Novel Protocols in an Ophthalmic Ambulatory Surgical Center to Resume Surgical Procedures During COVID-19.

BACKGROUND AND OBJECTIVES: With the resumption of elective ophthalmic surgery during COVID-19, revised protocols were mandated to protect both staff and patients from transmission while increasing case numbers. We discuss a widely generalizable and in-depth protocol intended to safely allow the restart of elective procedures in 2 dedicated ophthalmic ambulatory surgical centers (ASCs) using monitored anesthesia care. METHODS: A single-center review of protocols and practices designed to limit COVID-19 transmission. RESULTS: All patients were tested within 72 hours prior to the procedure with a COVID-19 nasal swab to assess for active disease. A distance of 6 ft between each stretcher and the staff within the ASC was maintained when possible. Preoperative anesthetizing and dilating eye drops were administered from multiuse bottles without contact with surfaces. Surgical cases were restarted at a reduced capacity of a maximum of 7 per day to distance patient arrivals. Removal of waiting room chairs and the creation of new break areas allowed for social distancing. CONCLUSION: As recommendations change on the basis of an increased understanding of the COVID-19 virus, ophthalmologists and ASC staff need to tailor protocols and workflows to limit transmission of virus with resumption of ocular surgery.
