Objective: To investigate the role of concomitant Internal Limiting Membrane (ILM) peeling during surgery for macula off Rhegmatogenous Retinal Detachment (RRD) in preventing postoperative Epiretinal Membrane (ERM) formation; and its effect on the visual acuity. Methods: This was a prospective, quasi-experimental study conducted from August 2018 to July 2019 at LRBT Tertiary Eye Care hospital, Karachi. Fifty-six patients with macula off RRD were divided into groups A (with ILM peeling) and B (without ILM peeling) via non-probability convenience sampling. All patients underwent standard 3 ports pars plana vitrectomy with silicon oil tamponade. In Group-A, ILM was stained using 0.5% ICG. Patients were evaluated clinically and by spectral domain optical coherence tomography (SD-OCT), pre- and post-operatively. Main outcomes recorded were best corrected visual acuity (BCVA) and occurrence of ERM on SD-OCT. Results: There were 26 patients in Group-A and 30 patients in Group-B. At six months’ follow-up, ERM had not developed in any case in Group-A compared to five patients (16.7%) in Group-B. There was no statistical difference in mean BCVA change from baseline. Conclusion: ILM peeling during vitrectomy for RRD prevents the formation of macular ERM post-operatively. This may reduce the need of a second vitrectomy. However, visual outcomes were comparable to the non-ILM peeling vitrectomy. doi: https://doi.org/10.12669/pjms.37.3.3576 How to cite this:Mahmood SA, Rizvi SF, Khan BAM, Khan TH.

Purpose To investigate the effects of internal limiting membrane (ILM) peeling on visual acuity (VA) after rhegmatogenous retinal detachment (RRD) surgery. Methods This retrospective analysis examined the medical records of patients with RRD who underwent vitrectomy at 26 institutions. To detect prognostic factors of VA at 6 months postoperatively (post-VA), multivariate linear regression was performed with post-VA as the objective variable; ILM peeling, sex, age, preoperative VA (pre-VA), intraocular pressure, axial length, duration of RRD, and cataract surgery served as explanatory variables. Recurrence of RRD and epiretinal membrane formation within 6 months postoperatively were compared between groups of patients with and without ILM peeling, among patients with macula-on and macula-off RRD. Results The inclusion criteria were met by 523 eyes with a macula-on RRD and 364 eyes with a macula-off RRD. ILM peeling was performed in 85 eyes with a macula-on RRD and 57 eyes with a macula-off RRD. In eyes with a macula-on RRD, ILM peeling did not affect post-VA (p = 0.72). Vitrectomy without cataract surgery and poor pre-VA were significantly associated with poor post-VA (p = 0.01 and p < 0.001, respectively). In eyes with a macula-off RRD, ILM peeling, long duration of RRD, and poor pre-VA were significantly associated with poor post-VA (p = 0.037, p = 0.007, and p < 0.001, respectively). Recurrence of RRD and epiretinal membrane formation were similar between groups of patients with and without ILM peeling, among patients with macula-on and macula-off RRD. Retina sensitivity was not evaluated by microperimetry. Conclusion ILM peeling did not affect post-VA in eyes with a macula-on RRD, whereas post-VA was worse in eyes with ILM peeling than in eyes without peeling, among eyes with a macula-off RRD.

AimTo study the role of internal limiting membrane (ILM) peeling in the prevention of macular epiretinal membrane (ERM) formation following pars plana vitrectomy (PPV) for rhegmatogenous retinal detachment (RRD).MethodsIn a randomised trial, patients with macula-off RRD (duration ≤3 months) with proliferative vitreoretinopathy grade ≤C1 and absence of pre-existing maculopathy were recruited from June 2016 to May 2018. Patients were randomised into two groups: group 1 (conventional treatment) underwent PPV alone, while group 2 underwent PPV with macular ILM peeling. The main outcome measures were macular ERM formation (detected on optical coherence tomography), corrected distance visual acuity (CDVA), retinal attachment and central macular thickness (CMT) at last follow-up (minimum 6 months).ResultsSixty patients (30 in each group) completed the required follow-up. The two groups were comparable in sex distribution, age, duration of RRD, baseline CDVA and duration of follow-up (median 15.5 vs 14 months). Macular ERM developed in 20% (n=6) and 0% of eyes in groups 1 and 2, respectively (p=0.002). Retinal reattachment was attained in all eyes. There was no statistical difference in final CDVA between the groups (p=0.43). Dissociated optic nerve fibre layer (DONFL) was found in 0% and 40% (n=12) of eyes in groups 1 and 2, respectively (p=0.0001). However, DONFL did not significantly affect the final CDVA (p=0.84). The final CMT was 266.0±37.5 µm and 270.0±73.7 µm in groups 1 and 2, respectively, with no statistical difference (p=0.62).ConclusionsILM peeling prevents macular ERM formation following PPV for RRD but provides similar visual outcomes as compared with conventional treatment.Trial registration numberCTRI2018/04/012978.

Purpose To assess the occurrence of peripheral vitreoschisis-induced vitreous cortex remnants (p-VCRs) in primary rhegmatogenous retinal detachment (RD) and investigate whether the presence of p-VCRs results in a greater risk of RD recurrence, secondary to Proliferative Vitreoretinopathy (PVR) development after pars plana vitrectomy (PPV). Methods Patients who underwent PPV for primary rhegmatogenous RD between January 2016 and December 2018 were included. The presence of residual p-VCRs was confirmed intraoperatively using triamcinolone acetonide (TA). Patients with p-VCRs were divided into two groups: Group A comprised of patients who underwent PPV without p-VCR removal, while Group B included patients who underwent PPV with p-VCR removal. Results Four hundred-thirteen eyes with evidence of p-VCR were analyzed. Two-hundred-twenty-three eyes underwent PPV without VCR removal (Group A), while 190 eyes underwent PPV with p-VCR removal (Group B). Primary anatomical success was 91.5% in the Group A and 95.4% in the group B. Retinal re-detachment due to PVR occurred in 17 (7.6%) eyes in Group A and in four (2.1%) eyes in Group B within the first 3 months (p  =  0.01). Among group A, in 11 eyes, there was a diffuse posterior PVR grade C, while six eyes were focal PVR grade C. In Group B, we observed four retinal re-detachment due to focal PVR grade C. Conclusion The presence of p-VCRs seems to be associated with a higher incidence of PVR development and might also result in more complex RD recurrence, this suggests the need for more aggressive VCRs removal during the first surgery.

Purpose. To describe the technique and outcomes of using either inverted or free internal limiting membrane flap in the management of retinal detachment due to paracentral retinal breaks. Methods. This retrospective observational case series includes nine patients who received surgery for retinal detachment due to paracentral retinal breaks developed either from primary rhegmatogenous origin, or secondary iatrogenic retinal breaks after prior membrane peeling, or during surgery for tractional retinal detachment. Either inverted or free internal limiting membrane flaps were inserted in the identified breaks, followed by air fluid exchange and gas tamponade. Visual acuity and structural changes were evaluated. Results. Nine eyes were included. One had primary rhegmatogenous retinal detachment, one had highly myopic eye with peripapillary atrophic hole, three had secondary retinal detachment after membrane peeling for foveoschisis or macular pucker, one had recurrent retinal detachment due to proliferative vitreoretinopathy, one had combination of tractional and rhegmatogenous retinal detachment, and two had iatrogenic breaks during surgery. The retinal breaks of all eyes were sealed with retina attached postoperatively. Visual acuity in logarithm of minimal angle of resolution improved from 1.18 ± 0.55 preoperatively to 0.74 ± 0.47 postoperatively (p=0.04). Conclusion. Internal limiting membrane flap technique can be a surgical approach selectively for retinal detachment due to paracentral retinal breaks with difficulty for laser application. The retina can be attached successfully and achieve good visual outcome without major complication. This trial is registered with NCT03707015.

Background. Rhegmatogenous retinal detachment associated with choroidal detachment (RRDCD) is rare and the prognosis is poor. This retrospective study evaluated the effect of preoperative steroid on the clinical outcome of patients with RRDCD receiving 23-gauge pars plana vitrectomy (PPV). Methods. Sixty-six patients (67 eyes) with diagnosed RRDCD underwent 23-gauge PPV. The patients assigned to receive systemic or subtenon injection of preoperative steroids were considered Group A (35 eyes) and did not receive are considered Control Group B (32 eyes). Most patients in Group A received subtenon injection of glucocorticoids. The cyclodialysis angle was measured with ultrasound biomicroscopy. Preoperative, intraoperative, and postoperative data were compared. Results. The rates of retinal reattachment in Group A after the first and second operations were 68.8% (24/35 eyes) and 91.43% (32/35 eyes), respectively, which were not significantly different from that of Group B (78.1%, 25/32 eyes; 96.6%, 31/32 eyes). The logMAR (logarithm of the minimum angle of resolution) visual acuity in Group A (1.63 ± 0.75) was similar to that of Group B (1.34 ± 0.74). Postoperative intraocular pressure and ocular hypertension in Group A (17.94 ± 9.82 mmHg and 37.1%, respectively; 13/35 eyes) were comparable to that of Group B (20.93 ± 10.21 mmHg and 56.3%; 18/32 eyes). Logistic regression analysis showed that postoperative reattachment was negatively associated with preoperative cyclodialysis angle as measured with ultrasound biomicroscopy (P=0.048) but was not significantly associated with preoperative steroid use (P=0.907). Conclusions. Preoperative steroid use does not improve retinal reattachment and visual acuity in patients with RRDCD after 23-gauge PPV. Preoperative measurement of the cyclodialysis angle with ultrasound biomicroscopy may be useful for predicting clinical outcomes.

ObjectiveTo compare the visual outcomes between macula-on and macula-off primary rhegmatogenous retinal detachment (RRD) based on the duration of macular detachment (DMD).Methods and AnalysisRetrospective study including 96 eyes with RRD (34 macula-on and 62 macula-off) repaired between June 2012 and March 2020. The final visual acuity (VA) was compared after the patients were divided by the status of the macula and their DMD.ResultsThe mean final VA of patients with macula-on RRD (group A) was logarithm of the minimum angle of resolution (logMAR) 0.04±0.07, which was not statistically different from that of individuals with macula-off RRD with DMD ≤3 days (group B; logMAR 0.05±0.06) (p=0.79). There were statistically significant differences in the final VA between group A and patients with macula-off RRD with DMD of 4–7 days (group C; logMAR 0.15±0.15) (p=0.017) as well as between group A and those with macula-off RRD with DMD ≥8 days (group D; logMAR 0.36±0.29) (p<0.001). There was no significant difference in the final VA between group B and C (p=0.33).ConclusionThe mean final VA of patients with macula-on RRD was comparable to that of the macula-off patients with DMD ≤3 days. Our findings suggest that if macula-on RRD could not be immediately repaired, a repair within 72 hours may result in similar outcomes, even if the macula detaches within that time frame. However, once the macula detaches, we do not observe statistically significant differences in outcome for repairs done within 7 days.
