Rate of pseudophakic cystoid macular edema using intraoperative and topical nonsteroidal antiinflammatory drugs alone without steroids.

PURPOSE: To determine the rate of postoperative cystoid macular edema (CME) in patients undergoing cataract surgery treated with intraoperative intracameral and postoperative topical nonsteroidal antiinflammatory drugs (NSAIDs) without steroids. SETTING: Academic outpatient surgery center Wake Forest Baptist Health in Bermuda Run, NC. DESIGN: Retrospective cohort study. METHODS: A retrospective chart review was performed. Patients were identified through a medical record search tool using criteria of the Current Procedural Terminology code (66984), a single surgeon, and a date range from January 1, 2016, through December 31, 2017. Medical records were reviewed to determine intraoperative and postoperative medication regimen, visual outcome, and development of postoperative CME. Patients with a history of uveitis, diabetic macular edema, retinal vein occlusions, epiretinal membranes, vitreomacular traction, or any prior macular edema were excluded. In addition, any patients with less than 6 weeks of postoperative follow-up were excluded. RESULTS: Overall, 824 patient records were reviewed, and the analysis included 504 eyes. Of these, 2 eyes developed postoperative CME (rate = 0.40%, 95% CI 0.0005 to 0.0143). CONCLUSIONS: The rate of CME in patients treated with intraoperative and postoperative NSAIDs without steroids was low and below the historical rates derived from a literature review of CME development with the use of steroids.

Bilateral exudative retinal detachments due to thrombotic microangiopathy associated with intravenous abuse of Opana ER.

PURPOSE: To report the only known case, to our knowledge, of bilateral exudative retinal detachments in the setting of thrombotic microangiopathy associated with intravenous abuse of extended-release oxymorphone (Opana ER). OBSERVATIONS: A 35-year-old male presented with headaches and acute, painless vision loss in the context of daily IV abuse of crushed oral Opana ER. The patient was found to have microangiopathic hemolytic anemia (MAHA), acute kidney injury in conjunction with hypertensive crisis and bilateral exudative retinal detachments. CONCLUSIONS AND IMPORTANCE: Bilateral exudative retinal detachments are rare ophthalmic complications that have been reported with thrombotic thrombocytopenic purpura (TTP). Non-TTP thrombotic microangiopathy, initially described as a "TTP-like illness" consisting of MAHA and thrombocytopenia, has been associated with the IV abuse of Opana ER. We report a case of bilateral exudative retinal detachments due to thrombotic microangiopathy in the setting of IV abuse of Opana ER.

Colorado retinopathy of prematurity model: a multi-institutional validation study.

PURPOSE: The Colorado retinopathy of prematurity (ROP) prediction model (CO-ROP), developed using a cohort of infants from Colorado, calls for ROP examination of infants meeting all of the following criteria: gestational age of ≤30 weeks, birth weight of ≤1500 g, and a net weight gain of ≤650 g between birth and 4 weeks of age. The purpose of this study was to perform an external validation to assess the sensitivity and specificity of the CO-ROP model in a larger cohort of babies screened for ROP from four academic institutions in the United States. METHODS: The medical records of neonates screened for ROP according current national guidelines was conducted at 4 US academic centers were retrospectively reviewed. Sensitivity, specificity, and respective 95% confidence intervals in detecting ROP using CO-ROP were calculated for type 1, type 2, and any grade of ROP. RESULTS: A total of 858 cases were included. The CO-ROP algorithm had a sensitivity of 98.1% (95% CI, 93.3%-99.8%) for type 1 ROP, 95.6% (95% CI 78.0-99.9%) for type 2 ROP, and 95.0% (95% CI, 93.1-97.4%) for all grades of ROP. The CO-ROP model would have reduced the total number of infants screened by 23.9% compared to current 2013 screening guidelines. CONCLUSIONS: CO-ROP demonstrated high sensitivity in predicting ROP and would have greatly reduced the number of infants needing examination.
