Purpose. To evaluate the significance of the area of epiretinal membrane (EM) that is not in contact with the retinal structure as a preoperative parameter for safer grasping of the EM and a prognostic factor for visual improvement/outcome.Methods. This prospective observational study included 73 consecutive patients (80 eyes) who underwent pars plana vitrectomy (PPV) and EM peeling. Corrected distance visual acuity (CDVA) and central foveal thickness (CFT) were evaluated preoperatively and at 12 months postoperatively. The number of initial peeling grasps was recorded in the operation protocol. The elevated EM portion was identified by en face optical coherence tomography (OCT) and processed digitally to calculate its area.Results. Surgery was found to significantly improve CDVA and decrease CFT. CDVA improvement correlated with elevated EM, preoperative CFT, and the number of grasping attempts.Conclusion. The detection of elevated EM via en face OCT could assist safer grasping of the EM and indicate the potential for visual outcome improvement after PPV and EM peeling.

AbstractWe evaluated predictive factors for visual outcomes in patients with idiopathic epiretinal membrane (iERM) after pars plana vitrectomy (PPV). Clinical records for 114 eyes (114 patients, mean age: 70.6 years) with iERM treated by PPV between March 2012 and March 2018 were retrospectively reviewed. Overall, the mean postoperative best-corrected visual acuity (BCVA) and central retinal thickness measured by optical coherence tomography improved as early as 1 month after surgery, and further improved until 3 months (P < 0.01). Multiple linear regression analyses adjusted for the preoperative BCVA showed that older age (B, 0.010; 95% confidence interval, 0.003 to 0.016; P = 0.003) and a shorter axial length (AL; B, −0.059; 95% confidence interval, −0.099 to −0.019; P = 0.005) predicted worse postoperative BCVA. The Mann-Whitney U test showed that the postoperative BCVA was worse in eyes with AL < 23.6 mm than in eyes with AL ≥ 23.6 mm (P = 0.037), and in patients aged ≥69 years than in patients aged <69 years (P = 0.024). The findings may help in evaluating surgical indications for each patient to obtain satisfactory outcomes, irrespective of the preoperative BCVA.

Purpose: Previous reports described unfavorable visual outcomes after surgery for uveitic macular pucker. Our goal was to demonstrate that patients with history of uveitis may benefit from vitrectomy for epiretinal membrane if executed under appropriate circumstances. Methods: We performed pars plana vitrectomy with ERM and ILM peeling in patients with post-uveitic macular pucker who did not show signs of ocular inflammation for at least 3 months after the suspension of immunosuppressive therapy. Visual acuity, central macular thickness at OCT, ocular inflammation, and complications were recorded. Results: Twenty-six eyes were operated. Mean duration of follow-up was 67 months. Visual acuity significantly improved from 20/80 to 20/40 after surgery. Vision increased in 20 (77%), remained stable in 4 (15%), and decreased in 2 (8%) eyes. Best-corrected visual acuity ameliorated by at least 2 ETDRS lines in 14 eyes (54%). Contingency analysis did not show any statistical difference among the different types of uveitis ( p = 0.46). Mean central foveal thickness improved postoperatively (428 ± 104 vs 328 ± 130 microns; p = 0.017). Conclusion: Patients with uveitic epiretinal membrane benefit from vitrectomy with membranectomy if operated when intraocular inflammation had subsided.

Purpose: Pars plana vitrectomy with internal limiting membrane peeling for idiopathic epiretinal membrane has shown varying results. More data are needed on the factors associated with visual outcome. Methods: We extracted baseline clinical characteristics, optical coherence tomography (OCT) characteristics and 3-month postoperative best-corrected visual acuity (BCVA). Linear regression analysis was used to evaluate whether baseline and OCT characteristics are associated with BCVA at 3 months as well as BCVA difference. Results: Out of 82 operated eyes, 66 (80%) had a 3-month follow-up, and 47 (71%) showed a 3-month postoperative improvement. Preoperative BCVA was an independent determinant of postoperative BCVA (r = 0.31; p < 0.01) and BCVA difference (r = 0.68; p < 0.01). Other baseline and OCT characteristics showed no independent associations with postoperative outcome. Conclusion: Better preoperative BCVA predicts better postoperative BCVA. Other baseline and OCT characteristics are not associated with visual outcome 3 months after surgery.

Purpose: To compare visual outcome and postoperative complications of combined 25-gauge pars plana vitrectomy and phacoemulsification with vitrectomy alone surgery in patients with epiretinal membrane and macular hole. Methods: A total of 110 eyes (73 eyes with epiretinal membrane and 37 eyes with macular hole) were enrolled in this prospective study. The eyes were divided into two groups: Group A included 55 eyes which underwent phacovitrectomy at the same time and Group B included 55 eyes which underwent vitrectomy alone. Follow-up visits were at 1, 3, and 6 months. Results: The best-corrected visual acuity correlation by analysis of variance measurement showed statistically non-significant differences between the two groups ( p = 0.32). The post hoc analysis from baseline, 1°, 2°, and 3° follow-ups was not statistically significant ( p > 0.05). The most common postoperative complication was cystoid macular edema that has been detected in 11 patients (10%) (seven eyes in Group A and four eyes in Group B): 2 patients (1.8%) developed a chronic macular edema. Intraocular hypertension occurred in five eyes (4.5%) (three in Group A and two in Group B). Four eyes (3.6%) underwent another surgical procedure for a persistent macular hole (two in Group A and two in Group B). The intraocular lens repositioning was performed one day after surgery in three eyes (2.7%) (Group A). The mean preoperative visual acuity was not different between the two groups ( p = 0.80). Conclusion: No significative differences between combined surgery and vitrectomy alone have been detected, in terms of postoperative complications and visual outcome.

Purpose. To investigate the functional and anatomical outcome of the 0.7 mg dexamethasone (Ozurdex) intravitreal implant (IVD) in eyes with long-term macular edema after macular epiretinal membrane removal. Methods. We enrolled 40 eyes with persistent macular edema at least 12 months after epiretinal membrane removal. Twenty eyes in the IVD group received IVD and the other 20 eyes were in the control group. The main outcome measures were change in best-corrected visual acuity (BCVA) and central foveal thickness (CFT). Results. For eyes in the IVD group, the mean BCVA improved by 3.45 lines to 0.47 logMAR one month after IVD. However, the mean BCVA improved by only 0.14 lines to 0.74 logMAR at the same time in eyes in the control group. Six months later, the mean BCVA improved to 0.31 and 0.74 logMAR in the IVD and control groups, respectively. In the IVD group, the mean CFT decreased rapidly by 116.8 μm to 333.9 μm one month after IVD. Thereafter the CFT decreased at a slower pace. In the control group, the CFT remained static during the follow-up period. However, in the IVD group, 6 months after IVD, the CFT seemed to have a tendency to increase. Conclusions. Single IVD could significantly decrease macular edema and improve visual outcome for eyes with persistent long-term macular edema after macular ERM removal and the effect can be sustained as long as 6 months after the initial injection. However, in order to maintain the visual and anatomical outcome, repeat IVD might be considered if macular edema recurs.

This report describes the first case of an ocular infection induced by Purpureocillium lilacinum in Poland. The patient was a 51-year-old immunocompetent contact lens user who suffered from subacute keratitis and progressive granulomatous uveitis. He underwent penetrating keratoplasty for corneal perforation, followed by cataract surgery due to rapid uveitic cataract. A few weeks later, intraocular lens removal and pars plana vitrectomy were necessary due to endophthalmitis. The patient was treated with topical, systemic, and intravitreal voriconazole with improvement; however, the visual outcome was poor. The pathogen was identified by MALDI-TOF MS.

Background/AimsPars plana vitrectomy (PPV) is widely performed in patients with idiopathic epiretinal membrane (iERM) to improve vision. Postoperative visual field defects (VFDs) have been previously reported. However, whether they occur when using the most recent PPV system, and the frequency of VFDs as measured by standard automated perimetry, remain poorly documented and were examined in this study.MethodsData of 30 eyes (30 patients; mean age, 66.1 years; 15 men) who underwent PPV for iERM during February 2016–June 2019 and had preoperative and postoperative visual field measurements using standard automated perimetry (Humphrey visual field analyser 30-2 program) were retrospectively analysed. Eyes with diseases other than iERM, including moderate-to-severe cataract or preoperative VFDs were excluded.ResultsVFD, defined by the Anderson and Patella’s criteria, was found in 73.3% of the eyes 1 month after PPV. After age adjustment, internal limiting membrane (ILM) peeling was identified as a risk factor for postoperative VFD (p=0.035; 95% CI 1.173 to 92.8). Postoperative VFD was frequently observed nasally (86.4%, p=0.002), and on optical coherence tomography measurements, ganglion cell layer (GCL) thinning was found temporal to the fovea (p=0.008). Thinning of the superior and inferior retinal nerve fibre layers and of the GCL temporal to the fovea were significant in eyes after ILM peeling (all p<0.05).ConclusionILM peeling may cause inner retinal degeneration and lead to the development of VFDs after PPV, which should be further examined.

Purpose: To identify prognostic factors for the visual outcome for patients with macula-off rhegmatogenous retinal detachment (RRD). Methods: The medical records of 27 patients (27 eyes) with macula-off RRD were retrospectively investigated. In addition to clinical characteristics, spectral-domain optical coherence tomography (SD OCT) images were analyzed. Results: The central foveal thickness at baseline was 923 ± 499.5 µm, and the mean height of the subretinal fluid was 697.8 ± 463.6 µm. Dropout of backreflection at the fovea was detected on preoperative SD OCT in 8 patients (29.6%). The external limiting membrane was disrupted in 5 patients (18.5%) as was the photoreceptor integrity in 9 patients (33.3%) at 12 months. On multiple regression analysis, backreflection integrity was the only predictive factor for postoperative visual outcome (B = 0.179, p = 0.020). Conclusions: Backreflection integrity on preoperative SD OCT seems to be helpful in predicting the postoperative visual outcome in macula-off RRD patients.
