ABSTRACT
To reveal optimal antibiotic prophylactic regimen for postoperative endophthalmitis (POE), we conducted systematic review and network meta-analysis. A total of 51 eligible original articles, including two randomized controlled trials, were identified. In total, 4502 POE cases occurred in 6,809,732 eyes (0.066%). Intracameral injection of vancomycin had the best preventive effect (odds ratio [OR] 0.03, 99.6% confidence interval [CI] 0.00-0.53, corrected P-value = 0.006, P-score = 0.945) followed by intracameral injection of cefazoline (OR 0.09, 99.6% CI 0.02-0.42, corrected P-value < 0.001, P-score = 0.821), cefuroxime (OR 0.18, 99.6% CI 0.09-0.35, corrected P-value < 0.001, P-score = 0.660), and moxifloxacin (OR 0.36, 99.6% CI 0.16-0.79, corrected P-value = 0.003, P-score = 0.455). While one randomized controlled trial supported each of intracameral cefuroxime and moxifloxacin, no randomized controlled trial evaluated vancomycin and cefazoline. Sensitivity analysis focusing on the administration route revealed that only intracameral injection (OR 0.19, 99.4% CI 0.12-0.30, corrected P-value < 0.001, P-score = 0.726) significantly decreased the risk of postoperative endophthalmitis. In conclusion, intracameral injection of either vancomycin, cefazoline, cefuroxime, or moxifloxacin prevented POE.

PURPOSE: Pregabalin binds to the α2-δ1/α2-δ2 subunits of the voltage-gated L-type calcium channel (LTCC), which is expressed in rod/cone photoreceptor terminals. The purpose of this report was to describe electroretinographic abnormalities associated with pregabalin treatment. CASE PRESENTATION: This is an observational case report. A 49-year-old female reported photophobia and night blindness in her left eye after 10 months of pregabalin administration. One month after the symptoms, ophthalmic examinations were performed, which revealed good visual acuity and no remarkable fundus findings. However, full-field electroretinography (ERG) of the left eye revealed a decreased b-wave in rod ERG, a slightly decreased a-wave and severely decreased b-wave (negative ERG) in bright flash ERG, decreased a- and b-waves in cone ERG, and decreased b-waves in 30-Hz flicker ERG. These findings are similar to those seen in incomplete congenital stationary night blindness, whereas the right eye ERG showed normal responses, except for a square a-wave in cone ERG. The ERG gradually improved from 1 to 12 months after discontinuing pregabalin. Finally, b-waves in bright flash ERG and cone ERG responses largely recovered, but b-waves in rod ERG and a-waves in bright flash ERG only partially recovered in the left eye. The square a-wave recovered to normal in the right eye. CONCLUSIONS: This is the first report to indicate that ERG abnormalities might be associated with pregabalin treatment. Our results suggest that pregabalin may affect LTCC function via the α2-δ1/α2-δ2 subunits, which leads to defective synaptic transmission from rod/cone photoreceptors to bipolar cells.
