Ophthalmol Retina 2024:S2468-6530(24)00049-6. [PMID: 38302055 DOI: 10.1016/j.oret.2024.01.023] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2023] [Revised: 12/17/2023] [Accepted: 01/23/2024] [Indexed: 02/03/2024]
Abstract
PURPOSE To report the clinical presentation and outcomes in patients who underwent surgery for proliferative sickle cell retinopathy (PSCR). DESIGN Retrospective, consecutive case series. SUBJECTS All patients who underwent vitreoretinal surgery for complications secondary to PSCR between January 1, 2014, and December 31, 2021, at a university referral center. METHODS Retrospective consecutive case series. MAIN OUTCOME MEASURES Best-corrected visual acuity (BCVA), single operation anatomic success rate. RESULTS The study included 65 eyes of 61 patients. Disease distribution included 24 (44.4%) eyes with hemoglobin SC disease, 14 (25.9%) with hemoglobin SS disease, 13 (24.1%) with sickle cell trait, and 3 (5.6%) with sickle cell-β thalassemia. Preoperative transfusion was not performed in any study patients. Regional anesthesia with monitored anesthesia care (RA-MAC) was utilized in 58 (89.2%) eyes and general anesthesia in 7 (10.8%). In eyes that underwent surgery for retinal detachment (RD; N = 52) the rate of single operation anatomic success was 72.4% with combined scleral buckling/pars plana vitrectomy (SB/PPV; N = 29) compared with 47.8% with PPV alone (N = 23; P = 0.07). Mean BCVA at the last follow-up examination was 1.27 (20/372) in the SB/PPV group and 1.05 (20/226) in the PPV group (P = 0.48). In all SB cases, an encircling band was utilized and there were no known cases of anterior segment ischemia. All eyes that had surgery for vitreous hemorrhage (N = 13) underwent PPV with endolaser and mean BCVA improved from 1.67 (20/944) preoperatively to 0.45 (20/56) at last follow-up examination (P < 0.001). Mean preoperative BCVA, indication for surgery, single operation success rate, and mean BCVA at last follow-up examination did not differ based on sickle cell disease type (P > 0.05). CONCLUSIONS In patients with RD, SB/PPV achieved slightly higher rates of single operation anatomic success compared with PPV alone. Visual acuity outcomes were similar in the 2 groups. The majority of patients received RA-MAC anesthesia and preoperative transfusions were not performed. There were no cases of postoperative anterior segment ischemia. Hemoglobin SC disease was the most common disease type in the current study and surgical outcomes did not differ between sickle cell disease types.

Abstract
PURPOSE To describe the epidemiology, indications and surgical results of pars plana vitrectomy (PPV) in patients over 85 years of age. METHODS A retrospective cohort study was performed including all consecutive patients aged 85 years or older who underwent PPV between September 2018 and March 2022 in a single hospital in Madrid, Spain. Data on diagnosis, comorbidities, surgical indication, surgical details, surgical complications and surgical outcomes were collected from medical records. RESULTS A total of 124 eyes of 119 patients (56 males, 47.1%) underwent PPV. Median age was 87 years (range 85-96). The most common surgical indications were complications of cataract surgery in 34 patients (28.6%), macular epiretinal membrane in 32 (26.9%), and rhegmatogenous retinal detachment (RRD) in 12 (10.1%). Mean preoperative best corrected visual acuity (BCVA) was 13.33 ± 42.34 ETDRS letters and improved to 40.05 ± 41.04 letters at 3 months (p < 0.001). BCVA had improved in 68.82% of patients at 3 months. Patients with chronic kidney disease (CKD; p < 0.001), RRD (p = 0.003), ocular trauma (p = 0.001) and age-related macular degeneration (AMD; p = 0.002) showed worse BCVA at 3 months from surgery. Patients with better preoperative BCVA (p < 0.001), and those who underwent 25G PPV (p = 0.041) showed better visual outcomes. CONCLUSIONS PPV is an effective technique for improving visual acuity in patients aged 85 years and older with vitreoretinal diseases. Visual outcomes were better when patients had a better preoperative visual acuity and underwent 25G PPV. Patients with a previous diagnosis of AMD or CKD, and those undergoing surgery for ocular trauma or RRD had worse visual outcomes.

Abstract
We evaluated the early effects of pars plana vitrectomy (PPV) on corneal biomechanics by comparing corneal hysteresis (CH) after cataract surgery (phacoemulsification and aspiration with intraocular lens implantation; PEA + IOL) alone and PPV combined with cataract surgery. This study included 20 eyes (18 patients), who underwent cataract surgery alone (PEA + IOL group), and 28 eyes (27 patients) who underwent PPV combined with cataract surgery (PPV triple group). The CH was 11.1 ± 1.1, 10.4 ± 1.1, and 11.0 ± 1.0 mmHg in the PEA + IOL group and 11.0 ± 1.4, 9.8 ± 1.4, and 10.6 ± 1.6 mmHg in the PPV triple group, preoperatively, at 2 weeks, and 3 months after surgery, respectively. The CH was not significantly different after surgery in the PEA + IOL group, but decreased significantly in the PPV triple group 2 weeks following surgery (p < 0.01). Intraocular pressure (IOP) and central corneal thickness (CCT) did not change significantly after surgery in either group. Preoperatively, there was a positive correlation between CH and CCT in the PPV triple group, but the correlation disappeared postoperatively. In PPV combined with cataract surgery, CH temporarily decreased postoperatively, independent of IOP and CCT. Removal of the vitreous may reduce the elasticity and rigidity of the entire eye.

Abstract
BACKGROUND AND OBJECTIVE Most surgeons now utilize small-gauge (23- or 25-gauge) pars plana vitrectomy (PPV) with or without scleral buckling for repair of rhegmatogenous retinal detachments (RRD), in addition to primary scleral buckle (SB), but comparative data between the two gauges are limited. PATIENTS AND METHODS This study is an analysis of primary RRD repairs comparing 23- versus 25-gauge vitrectomy for PPV or combination PPV/SB from January 1, 2015, through December 31, 2015, across multiple institutions. The primary outcome was single-surgery success and secondary outcomes included postoperative complications. RESULTS There were 1,932 eyes that met inclusion criteria. There was no statistically significant difference in single-surgery success (82.9% vs. 83.8%; P = 0.6329). There were similar rates of postoperative hypotony, endophthalmitis, vitreous hemorrhage, and choroidal detachment. The findings were similar when analyzing only eyes that underwent primary PPV without SB. CONCLUSION Both 23- and 25-gauge vitrectomy systems have similar anatomic and visual outcomes in the primary repair of RRD. [Ophthalmic Surg Lasers Imaging Retina. 2021;52:70-76.].

Abstract
PURPOSE We hypothesised that cleaning the internal limiting membrane (ILM) with a flexible nitinol loop following diabetic vitrectomy without peeling may reduce the common occurrence of postoperative epiretinal membrane (ERM) formation. METHODS Consecutive patients undergoing vitrectomy for proliferative diabetic retinopathy by one surgeon from 2015 to 2019 were studied and divided into 2 cohorts: the control group underwent standard surgery, and the ILM clean group underwent additional cleaning of the macular retina using a flexible nitinol loop after vitrectomy. Masked comparison of ERM on optical coherence tomography was performed at 3 months, and visual acuity (VA) was measured until 12 months postoperatively. RESULTS Baseline demographics, clinical features, and protein levels were similar between cohorts. The ILM clean group (n = 56) had fewer clinically significant ERM than the control group (n = 50; 4 vs. 20%; p = 0.01), and a significantly lower proportion of the ILM clean group required revision surgery (2 vs. 14%; p = 0.02). VA in the ILM clean group was significantly better than in the control group at 3 months (0.35 vs. 0.50 logMAR; p = 0.02) but not at 12 months (0.34 vs. 0.43 logMAR; p = 0.17). CONCLUSION ILM cleaning with a flexible nitinol loop following diabetic vitrectomy resulted in significant reduction in ERM formation and reduced necessity for revision surgery. There was significant improvement in VA at 3 months but not over a longer follow-up.

Abstract
Tractional retinal detachment is an end-stage form of diabetic retinopathy that occurs when contractile forces in the vitreous and neovascular tissue lead to the detachment of the neurosensory retina. We review the literature related to the management of this disease. Preoperative planning includes appropriate patient selection, diagnostic and prognostic imaging, and medical optimization with reduction of systemic risk factors. Use of antivascular endothelial growth factor for preoperative treatment has had significant benefits for tractional retinal detachment repair in improving surgical efficiency and outcomes. Advances in microsurgical instrumentation are discussed, with attention to small-gauge vitrectomy with improved flow dynamics, viewing strategies, and lighting allowing bimanual surgery. Special emphasis is placed on bimanual surgical technique, choice of tamponade, and the avoidance of iatrogenic damage. Complications and special considerations are further explored. Based on our compilation of relevant literature, we propose a surgical algorithm for the management of these complex patients.

Abstract
Purpose To report characteristics and visual results in patients with PDR-associated complications following pars plana vitrectomy (PPV) in a tertiary center over an eight-year period. Methods Medical records of diabetic retinopathy patients receiving PPV between January 2007 and December 2014 for PDR-related complications were reviewed. Results A total of 890 consecutive PDR patients were included in the study. PPVs were performed for tractional retinal detachment (36.6%), persistent vitreous hemorrhage (VH) (35.4%), combined tractional and rhegmatogenous retinal detachment (14.5%), and vitreoretinal abnormalities (13.5%), respectively. Preoperative intravitreal bevacizumab injection (IVB) within two weeks prior to PPV and 23G vitrectomy systems was found to decrease the risk for intraoperative retinal break development (P=0.045 and P=0.015, respectively). The incidence of early dense postoperative VH decreased significantly with the administration of preoperative or intraoperative IVB at the end of PPV. Postoperative visual results significantly correlated with the initial visual acuity level, intraoperative retinal break development, and retained silicone oil tamponade at the final visit (P < 0.001, P=0.040, and P=0.044, respectively). Administration of adjuvant IVB either before or at the end of PPV had no significant association with the final visual outcomes. Conclusions This study reported an improvement in visual acuity in nearly half of patients receiving PPV for PDR-associated complications in a limited resource center. The incidence of intraoperative retinal break and early postoperative VH decreased significantly with the application of IVB injections. Poor final visual outcomes were related to the lower initial visual acuity levels, intraoperative retinal breaks, and postoperative retained silicone oil.

Abstract
Purpose: To evaluate the feasibility and outcomes of the sole use of 23g pars plana vitrectomy in cases with diabetic vitreous hemorrhage with vitreoretinal traction. Methods: Prospective interventional case series involving patients between January 2013 and January 2018. All eyes underwent 23g pars plana vitrectomy with internal tamponade. Intraoperative parameters including ancillary instruments, the methods used for hemostasis and complications were all recorded. Postoperative parameters including anatomic success rate, functional success, and postoperative complications were recorded and analyzed. Patients were followed up for at least 12 months. Results: A total of 68 eyes of 66 patients were included. Intraoperative ancillary instruments were required in 5 (7.4%) eyes. None of the cases required the use of chandelier illumination, endodiathermy, or scissors. Mean best-corrected visual acuity improved significantly from LogMAR 1.67 ± 0.63 preoperative to 1.22 ± 0.38 at 1-year follow-up (P = 0.005). Functional success was achieved in 37 (54.4%) eyes at 1-year follow-up. Iatrogenic breaks occurred in 3 (4.4%) eyes, vitreous hemorrhage in 4 (5.9%) eyes, and epiretinal membranes in 3 (4.4%) eyes. Repeated vitrectomy was done in 3 (4.4%) eyes. Conclusion: The 23g vitrectomy probe proved to be a safe, effective, and beneficial single tool that could accomplish the diabetic vitrectomy mission exclusively with minimal aid from other instruments in cases with vitreous hemorrhage associated with vitreoretinal traction.

Abstract
PURPOSE To determine the annual incidence of visual impairment in a Japanese population during a 10-year period. METHODS We examined the physical disability certificates issued yearly between 2004 and 2013 in Mie prefecture, Japan. During this period 2468 visually impaired people were registered under the newly defined Act on Welfare of the Physically Disabled Persons' criteria. The age, sex distribution, and causes of visual impairment were determined from the certificates. RESULTS The major causes of visual impairment during the ten-year period were glaucoma (23.3%), diabetic retinopathy (17.3%), retinitis pigmentosa (12.2%), macular degeneration (9.0%), chorioretinal degeneration or high myopia (7.4%), optic atrophy (5.8%), stroke or brain tumor (5.4%) and cataracts (3.7%). The incidence of glaucoma was significantly higher throughout the period (2004-2013), and that of diabetic retinopathy was lower between 2007 and 2013. The incidence of retinitis pigmentosa did not change significantly during the 10-year period. The incidence of macular degeneration tended to increase between 2004 and 2007, but it decreased significantly between 2007 and 2013. CONCLUSIONS The results indicate that in Japan, the rates of the major causes of visual impairment altered in the most recent 10-year period reflecting the recent changes in the social background and advances in ocular and systemic treatment.

Abstract
PURPOSE To evaluate the short- and long-term surgical and clinical outcomes in eyes with diabetic tractional retinal detachment (TRD) undergoing 25-G+ pars-plana vitrectomy (PPV). METHODS A total of 238 patients were reviewed for inclusion in this study. A retrospective cohort study of 109 eyes of 73 patients operated on for diabetic TRD were included. All eyes received intraocular tamponade of air, sulfur hexafluoride, octofluropropane or silicone oil. All patients were followed up for a minimum period of one year. RESULTS The mean age of all patients at surgery was 53.9 years ± 9.2, while the mean duration of diabetes was 18.7 ± 10.4 years. The mean length of follow-up was 923 ± 87 days after surgery (range, 432-1792 days). Thirty-two cases (29.3 %) had an associated rhegmatogenous component. Mean BCVA improved from logarithm minimum angle of resolution (logMAR) 1.17 (20/300) to 0.812 (20/130) (p < 0.05). All eyes underwent intraoperative laser photocoagulation. Primary, single-surgery anatomic reattachment was achieved in 99 eyes (91 %). Final anatomic attachment was achieved in 107 eyes (98 %). There was no statistically significant difference in primary or secondary re-attachment rate in terms of type of tamponade agent used. There were five cases of post-operative hypotony (≤5 mmHg) on postoperative day 1, while 11 eyes had IOP ≥ 30 mmHg. There were no cases of endophthalmitis in our cohort. CONCLUSIONS 25G+ PPV provides for safe and effective repair of diabetic TRDs. Patients experienced positive functional and anatomic outcomes, with no significant intraoperative complications and minimal postoperative sequelae.
