We aim to evaluate magnitudes of higher order aberrations (HOAs) from 3rd-6th order after scleral buckling (SB) for rhegmatogenous retinal detachment (RRD). A retrospective cross-sectional study of 19 patients with RRD who received SB (six receiving encircling SB, thirteen receiving segmental SB) was conducted. A wavefront analysis for surveying HOAs and other ophthalmic parameters were collected. Data between operated and fellow eyes, and a subgroup analysis of operated eyes, were analyzed by the Mann–Whitney U test, while a generalized linear model was applied to evaluate the correlation of HOAs to best-corrected visual acuity (BCVA) and optical symptoms. BCVA in the operated eyes was significantly worse (LogMAR: 0.18 ± 0.23 versus 0.05 ± 0.07, p = 0.001). Tilt (0.32 ± 0.14 versus 0.13 ± 0.08, p = 0.004), defocus (1.78 ± 0.47 versus 1.05 ± 0.17, p = 0.019) and coma (0.43 ± 0.11 versus 0.27 ± 0.09, p = 0.016) were significantly increased after SB. All root mean square (RMS), including RMS-3, RMS-4 and total RMS, were higher in operated eyes (all p < 0.05). Regarding Zernike terms, a significant elevation of vertical coma in the operated eyes was found (p = 0.038). In addition, tilt (0.41 ± 0.10 versus 0.17 ± 0.12, p = 0.007), defocus (2.27 ± 0.58 versus 0.82 ± 0.39, p = 0.001) and coma (0.59 ± 0.17 versus 0.11 ± 0.10, p = 0.015) were higher in the segmental subgroup, whereas spherical aberration (SA) was higher in the encircling subgroup (0.22 ± 0.04 versus 0.40 ± 0.15, p = 0.024) and RMS-4 and total RMS were increased in the segmental subgroup (both p < 0.05). Besides, tilt was correlated to worse BCVA (p = 0.036), whereas all four HOAs were correlated to the presence of optical symptoms (all p < 0.05). In conclusion, SB may increase HOAs, which could be associated with unfavorable postoperative visual outcomes and subject symptoms.

Purpose: The aim of this study is to evaluate the root mean square error (RMS) of corneal higher- order aberrations in Syrian adult population in different refractive status (emmetropia, myopia, hyperopia and simple myopic astigmatism). Methods: This cross- sectional study was conducted at Tishreen University Hospital in Latakia, Syrian Arab Republic. A total of 420 patients (840 eyes), ages 18- 40 years, participated in the study. Refraction was measured with an autorefractor keratometer and expressed as a spherical equivalent. Total corneal higher- order aberrations (Coma, Spherical Aberration, Trefoil) were measured using Sirius Corneal Topography at a pupil diameter of 5 mm. Results: RMS of Coma and Spherical aberrations peaked in the hyperopia group (0.18 ± 0.08, 0.11 ± 0.02) respectively. Whereas, Trefoil was higher in the severe myopia and simple myopic astigmatism groups (0.25 ± 0.05, 0.25 ± 0.08) respectively. Conclusions: Among a Syrian population, some types of refractive status were associated with certain types of higher- order aberrations, with a significant increase in trefoil in severe myopia and simple myopic astigmatism.

Purpose To introduce a modified scleral buckling surgery using noncontact wide-angle viewing system and intraocular illumination in the treatment of rhegmatogenous retinal detachment (RRD) without proliferative retinopathy. Methods A modified scleral buckling surgery using noncontact wide-angle viewing system with a 25-G optic fiber through sclerotomy site was performed in 22 eyes of 22 patients with RRD. Twelve women and 10 men were included. The mean age was 49.23 ± 15.19 years. The mean refraction of myopia was -4 D (range -3 to -7 D). The mean duration of RRD was 6.64 ± 3.14 days. The preoperative best-corrected visual acuity (BCVA) ranged from 0.02 to 0.8. Mean follow-up was 9.59 ± 2.24 months. Proliferative retinopathy was grade A in 8 eyes and grade B in 14 eyes. Results This surgery was performed successfully and retinal attachment was achieved in all eyes at the final follow-up. The postoperative BCVA increased in all eyes. No complication was encountered related to this technique. Conclusions This modified scleral buckling surgery brings a panoramic and upright view and easy surgical maneuvers. It may be an additional approach for the management of RRD.

Abstract This paper aims to calculate a relevance model of visual limitation (V.L.) in keratoconus patients based on refractive and topographic parameters. A cross-sectional study was carried out in Torrecárdenas Hospital, Almería, Spain, between February 2018 and July 2019. It included 250 keratoconus patients. Two groups were created according to a grading system of V.L. based on RETICS (Red Temática de Investigación Cooperativa en Salud) classification: keratoconus patients with no V.L. (best spectacle-corrected visual acuity (BSCVA) ≤ 0.05 logMAR) and keratoconus patients with V.L. (BSCVA > 0.05 logMAR). Correlations and a binary logistic regression were established. V.L. was correlated with maximum curvature (r = 0.649, p < 0.001) and root mean square higher-order aberrations (HOARMS) (r = 0.625, p < 0.001). Binary logistic regression included V.L. as the dependent variable and spherical equivalent, HOARMS, spherical aberration and interaction between the anterior and posterior vertical coma as independent variables. The model was a good fit. Area under the curve (A.U.C.) of receiver operating characteristic (R.O.C.) curve was 0.924, sensitivity 91.90%, specificity 83.60%, accuracy 88.94%; and precision 91.17%. Binary logistic regression model of V.L. is a good fit model to predict the early loss of visual acuity in keratoconus patients.

Objective: To study the anatomical status and visual outcome of scleral buckling surgery in rhegmatogenous retinal detachment (RRD) at tertiary eye care center in Nepal. Method: This is a prospective, noncomparative, consecutive, interventional study of rhegmatogenous retinal detachment managed with scleral buckling surgery performed in Lumbini Eye Institute, Nepal. All the patients underwent surgery by a single experienced surgeon and had at least 3 months follow up. Result: A total of 50 patients (50 eyes) were operated, 38 males and 12 females, with a mean age of 39.46. Retinal reattachment was achieved in 46 (92%). Improved best corrected visual acuity (BCVA) was seen in 84%, whereas in 8% BCVA was same and deteriorated in another 8%. Conclusion: Rhegmatogenous retinal detachment is one of the common causes of visual impairment and blindness. Timely surgical management with scleral buckling surgery can give good anatomical and visual outcome.

Purpose: To report a case of surgical repair of traumatic rhegmatogenous retinal detachment combined with congenital falciform retinal detachment (FRD). Methods: A retrospective case report. Results: A 36-year-old man with traumatic rhegmatogenous retinal detachment complicating a previously known FRD was successfully treated despite residual FRD following pars plana lensectomy, vitrectomy, and encircling scleral buckling. His best corrected visual acuity improved from hand motion at 50 cm to 20/1,000. Conclusion: We concluded that the root of the FRD is susceptible to trauma because of the contraction of fibrovascular tissue. The early intervention of modern vitrectomy to traumatic rhegmatogenous retinal detachment complicating a previously known FRD is an important consideration for enhanced quality of care and optimal patient outcomes.

Purpose To evaluate the outcomes and complications of scleral buckle surgery alone or combined with pneumatic retinopexy (pneumatic buckle) for the treatment of primary rhegmatogenous retinal detachment. Design Retrospective chart review. Participants Two hundred thirteen patients with rhegmatogenous retinal detachment of whom 101 underwent primary scleral buckle surgery at Rabin Medical Center in 2005–2015 (SB group) and 112 underwent pneumatic buckle surgery at Royal Alexandra Hospital in 2013–2015 (PB group). Methods All patients were followed for ≥12 months. Data on clinical and surgical parameters, outcome, and complications were collected from the medical files. Main Outcome Measures Best corrected visual acuity and anatomical outcomes. Results At 12 months, average best corrected visual acuity was 0.3 logMar in the SB group and 0.42 logMar in the PB group ( P < 0.05). Rates of anatomical reattachment were high and similar in the two groups (99% and 97%, respectively, P = 0.623). The SB group had a higher percentage of patients requiring additional laser applications (21% vs. 7%; P < 0.01) and buckle readjustment surgery (6% vs. 0; P = 0.01), and the PB group had a higher percentage of patients who required postoperative pars plana vitrectomy (30% vs. 17%; P = 0.03). Conclusion Scleral buckle surgery alone is efficient for the treatment of rhegmatogenous retinal detachment. Its combination with pneumatic retinopexy usually has no significant added value in terms of anatomical reattachment rate. Outcomes of Pneumatic buckling vs Scleral Buckling for RRD

Abstract Background: To evaluate the efficiency and safety of 25-gauge illumination aided scleral buckling surgery combined with intravitreal injection of hyaluronate for treatment of rhegmatogenous retinal detachment Methods: This study was undertaken in a prospective, nonrandomized, and uncontrolled manner. Patients of rhegmatogenous retinal detachment were performed scleral buckling surgery with the aid of intraocular illumination and noncontact wide-angle viewing system. Hyaluronate was injected into the vitreous cavity to maintain intraocular pressure stable after subretinal fluid drainage through the external sclerotomy when necessary. Best corrected visual acuity(BCVA), intraocular pressure, fundus examination and complications were observed and recorded. Results: Twenty-eight consecutive patients (28 eyes) were enrolled. Subretinal fluid drainage and hyaluronate injection was performed in 12 eyes. The final reattachment ratio was 100%. BCVA increased after operation (P<0.001) and no significant difference was observed between preoperative and postoperative intraocular pressure (P=0.149). No iatrogenic retinal break, choroidal hemorrhage or endophthalmitis were observed. Conclusions: Endoillumination aided buckling surgery combined with intravitreal injection of hyaluronate could be an option for treatment of rhegmatogenous retinal detachment especially for the cases of highly elevated retina. Trial registration: ChiCTR1800020055. Retrospectively registered on December 12, 2018. Key words: Rhegmatogenous retinal detachment, scleral buckling, noncontact wide-angle viewing system, endoillumination, intravitreal injection of hyaluronate.
