INTRAVITREAL OCRIPLASMIN IN CLINICAL PRACTICE Predictors of Success, Visual Outcomes, and Complications

Purpose: To investigate predictors of success, visual outcomes, and complications of intravitreal ocriplasmin for the treatment of symptomatic vitreomacular adhesion in a clinical care setting. Methods: Retrospective chart review of 49 consecutive eyes of 47 patients who received intravitreal ocriplasmin. Spectral domain optical coherence tomography scans were examined for vitreomacular traction (VMT) release, full-thickness macular hole (FTMH) closure, and other changes in retinal anatomy. Results: Pharmacologic VMT release occurred in 41% of eyes; positive predictors included age <= 75 years (P = 0.001), phakic status (P = 0.016), VMT width <= 750 mu m (P = 0.001), and absence of retinal comorbidities (P = 0.035). Pharmacologic FTMH closure occurred in 25% of cases; positive predictors included successful VMT release (P = 0.042), better preinjection best-corrected visual acuity (P = 0.036), and smaller FTMH aperture width (P = 0.033). Eyes that achieved VMT release and did not undergo surgery attained significant improvement in best-corrected visual acuity (P = 0.015). Complications included subfoveal lucency (33%), ellipsoid zone disruption (33%), and FTMH base enlargement (75%). Only FTMH base enlargement resulted in worse visual outcomes (P = 0.024). Subgroup analysis of 14 eyes with ideal characteristics (all positive predictors listed above) yielded a 93% VMT release rate. Conclusion: Proper case selection may facilitate successful pharmacologic vitreolysis with ocriplasmin, improve visual outcomes, and minimize potential complications.
