Randomized Controlled Trial Comparative Study
Targeted Retinal Photocoagulation for Diabetic Macular Edema with Peripheral Retinal Nonperfusion: Three-Year Randomized DAVE Trial.
To evaluate the effect of targeted retinal photocoagulation (TRP) on visual and anatomic outcomes and treatment burden in eyes with diabetic macular edema (DME). ⋯ In this 3-year randomized trial of 40 eyes with DME, there was no evidence that combination therapy with ranibizumab and TRP improved visual outcomes or reduced treatment burden compared with ranibizumab alone.

To describe characteristics of closed medical professional liability (MPL) claims against ophthalmologists in the United States. ⋯ Ophthalmology has a relatively low number of malpractice claims reported compared with other healthcare specialties and shows less spending on average indemnity and defense. Further studies are needed to investigate the reasons for the higher prevalence of claims related to cataract and corneal surgeries and the higher average indemnity paid for corneal procedures relative to vitreoretinal or oculoplastic procedures.

Evidence-based medicine is guided by our interpretation of randomized controlled trials (RCTs) that address important clinical questions. Evaluation of the robustness of statistically significant outcomes adds a crucial element to the global assessment of trial findings. The purpose of this systematic review was to determine the robustness of ophthalmology RCTs through application of the Fragility Index (FI), a novel metric of the robustness of statistically significant outcomes. ⋯ In ophthalmology trials, statistically significant dichotomous results are often fragile, meaning that a difference of only a couple of events can change the statistical significance. An application of the FI in RCTs may aid in the interpretation of results and assessment of quality of evidence.
