Purpose: Aim of the present study was to analyze the effect of phacoemulsification on outcomes among patients undergoing vitrectomy with membrane peeling for idiopathic epiretinal membranes, with respect to new postoperative intraretinal cystoid changes and early transient macular edema. Procedures: This retrospective analysis included patients from six prospective studies, examining outcomes of 23G pars plana vitrectomy with membrane peeling due to idiopathic epiretinal membranes. Phacovitrectomy with membrane peeling was performed only in case of coexisting vision affecting cataract. Optical coherence tomography was performed prior to surgery, in the first week and 3 months after surgery. Results: In total, 183 patients were included. Occurrence of new postoperative intraretinal cystoid changes and early transient macular edema showed a trend to be higher among patients undergoing phacovitrectomy with membrane peeling, compared to vitrectomy with membrane peeling alone, but did not reach statistical significance (p=0.5 and p=0.186). Final BCVA 3 months after surgery was significantly lower among patients with new postoperative intraretinal cystoid changes, compared to patients without (with a median difference of 1 line between groups, p=0.016). Conclusions: New postoperative intraretinal cystoid changes and early transient macular edema are more frequent among patients undergoing phacovitrectomy with membrane peeling, compared to patients with vitrectomy with membrane peeling alone.

Background: Diabetes mellitus remains the leading cause of blindness among working age Americans with diabetic macular edema being the most common cause for moderate and severe vision loss. Objective: To investigate the anatomical and visual benefits of pars plana vitrectomy with inner limiting membrane peeling in patients with nontractional diabetic macular edema as well as correlation of integrity of outer retinal layers on spectral domain optical coherence tomography to visual outcomes. Methods: We retrospectively reviewed the charts of 42 diabetic patients that underwent vitrectomy with internal limiting membrane peeling for nontractional diabetic macula edema. The integrity of outer retinal layers was evaluated and preoperative central macular thickness and visual acuity were compared with data at 1 month, 3 months and 6 months postoperatively. The student t-test was used to compare the groups. Results: 31 eyes were included. While no differences were seen at 1 and 3 months, there was significant improvement of both central macular thickness and visual acuity at the 6 months follow up visit compared to preoperatively (357, 427 microns; p=0.03. 20/49, 20/82; p=0.03) . Patients with intact external limiting membrane and ellipsoid zone had better preoperative vision than patients with outer retinal layer irregularities (20/54, 20/100; p=0.03) and greater visual gains postoperatively (20/33, p<0.001 versus 20/81; p=non-significant). Conclusion: Pars plana vitrectomy with internal limiting membrane peeling can improve retinal anatomy and visual acuity in patients with nontractional diabetic macular edema. Spectral domain optical coherence tomography may help identify patients with potential for visual improvement.

Abstract Background To evaluate changes in anterior segment morphology on anterior segment optical coherence tomography (AS-OCT) following pars plana vitrectomy (PPV) without tamponade. Methods Patients who underwent PPV without tamponade for epiretinal membrane were evaluated. Eligible patients underwent intraocular pressure (IOP) measurement and AS-OCT preoperatively as well as 1 month and 6 months post-operatively. Anterior chamber width (ACW), anterior chamber depth (ACD), trabecular iris angle (TIA), angle opening distance at 500 and 750 µm (AOD), and trabecular iris space area at 500 and 750 µm (TISA) at four quadrants were recorded and analyzed. Additionally, the mean values of TIA (MTIA), AOD (MAOD), and TISA (MTISA) for each eye (mean of four quadrants) were analyzed. Results 23 patients completed the study. The mean age of participants was 56.4 ± 3.6 years of age and 13/23 (56%) were female. Mean IOP of patients was 18.1 ± 1.1, 18.3 ± 1.1, and 18.1 ± 1.2 preoperatively,1 month post-operatively, and 6 months post-operatively, respectively. (p = 0.83). No difference was detected post-operatively in measurements of ACW, ACD, MTIA, MAOD500, MAOD750, MTISA500, and MTISA750. Conclusion Pars plana vitrectomy without tamponade was not associated with changes in anterior chamber morphology.

Aim: To demonstrate the morphological outcomes of macular hole following prophylactic peripheral laser retinopexy (PPLR). Methods: Our retrospective case-control analysis included 92 eyes, 55 in the laser group and 37 in the non-laser group. Fifty-five patients were subjected to prophylactic peripheral laser retinopexy in preparation for pars plana vitrectomy for macular hole, with and without vitreomacular adhesion (laser group). Before and after prophylactic peripheral laser retinopexy, we evaluated any changes in vitreomacular anatomy by optical coherence tomography. Optical coherence tomography changes were also analyzed in the visits preceding pars plana vitrectomy in 37 macular hole eyes not subjected to prophylactic peripheral laser retinopexy (non-laser group). Results: In the laser group, 7 out of 55 eyes (12.7%) showed macular hole closure (6 out of 18 macular hole eyes with vitreomacular adhesion (33.3%) and 1 out of 37 eyes without vitreomacular adhesion (2.7%)), while no patients showed macular hole closure in the non-laser group (p < 0.05). The mean width of the seven closed macular hole was 191.4 µm (range: 59–282 µm). In all except one of the six macular hole eyes with vitreomacular adhesion, the macular hole closed without vitreomacular adhesion release. In our analysis of the patient subgroup with vitreomacular adhesion, we observed a release of vitreomacular adhesion in 3 out of 18 eyes (16.6%) in the laser group and in 1 out of 13 eyes (7.6%) in the non-laser group (p > 0.05). Conclusion: These findings support a possible beneficial role for prophylactic peripheral laser retinopexy in selected individuals with macular hole.
