Purpose To evaluate the effects of epiretinal membranes on the response of uveitic macular edema to therapy and on visual acuity outcomes. Design Retrospective case series. Methods 104 eyes of 77 patients with uveitic macular edema were identified at a tertiary care center. Epiretinal membranes were diagnosed when identified by two investigators’ grading of spectral-domain optical coherence tomography and scored for the presence or absence of surface wrinkling. Outcomes included best corrected visual acuity, central subfield thickness, and rates of macular edema improvement (>20% reduction in central subfield thickness) and resolution (reduction of central subfield thickness to <315 μm) at 3 and 6 months follow-up. Results 72 eyes of 59 patients had an epiretinal membrane on presentation. Eyes without epiretinal membranes and with epiretinal membranes without surface wrinkling were not significantly different at presentation or at 3 and 6 months follow-up. Conversely, eyes with an epiretinal membrane with retinal surface wrinkling had a greater proportion of eyes with 20/200 or worse visual acuity at presentation, and had worse mean acuities at 3 months (20/94 vs. 20/35 for eyes without an epiretinal membrane, P=0.002) and at 6 months follow-up (20/110 vs. 20/36 for eyes without an epiretinal membrane, P=0.02). At 6 months of follow-up the mean central subfield thicknesses were: eyes without an epiretinal membrane, 338 ± 23 μm; and eyes with an epiretinal membrane and surface wrinkling, 405 ± 22 μm (P=0.05). Conclusions In eyes with epiretinal membranes and retinal surface wrinkling, uveitic macular edema had a poorer visual acuity response to medical therapy and thicker maculae at 6 months.

These data suggest that decreases in plasma free-VEGF levels are greater after treatment with aflibercept or bevacizumab compared with ranibizumab at 4 weeks. At 52 and 104 weeks, a greater decrease was observed in bevacizumab versus ranibizumab. Results from 2 subgroups of participants who did not receive injections within at least 1 month and 2 months before collection suggest similar changes in VEGF levels after stopping injections. It is unknown whether VEGF levels return to normal as the drug is cleared from the system or whether the presence of the drug affects the assay's ability to accurately measure free VEGF. No significant associations between VEGF concentration and systemic factors were noted.

Paintball trauma results in significant ocular injury and loss of vision. Most injuries occur in unsupervised settings without proper eye protection. Ten patients (71%) were injured in accidental or intentional shootings. Lack of supervision and use of paintball materials as assault weapons make the risk for ocular injury more significant. Improved safety features of paintball equipment, along with continued education of proper eye protection, may reduce the incidence of severe ocular injuries.
