RESUMO
TOPIC: This systematic review and meta-analysis investigates the efficacy and safety of anti-vascular endothelial growth factor (anti-VEGF) injections compared to surgical intervention in improving visual acuity (VA) and reducing complications for patients with submacular hemorrhage (SMH) due to neovascular age-related macular degeneration (AMD). CLINICAL RELEVANCE: Determining the optimal intervention for SMH in AMD is crucial for patient care. METHODS: We included studies on anti-VEGF injections or surgical interventions for SMH in AMD from 7 databases, searched up to May 2024. Data extraction and quality assessment were done by two independent reviewers. Certainty of evidence was assessed GRADE approach. Meta-analysis employed random-effects models. Primary outcomes were pooled mean logMAR VA difference (initial examination minus last follow-up VA) and adverse events rates. RESULTS: A total of 43 observational studies were included: 21 (960 eyes) on anti-VEGF and 22 (455 eyes) on surgery. Comparisons were made across separate studies due to lack of head-to-head studies. Meta-analysis included 11 anti-VEGF studies (444 eyes) and 12 surgical studies (195 eyes) for VA outcomes. The mean difference (MD) in VA was -0.16 (95%CI: -0.26,-0.07) for anti-VEGF and -0.36 (95%CI: -0.68,-0.04) for surgery, with no significant difference between groups (X2=1.70, df =1, p=0.19). Heterogeneity was high in surgical studies (I2=96.2%, tau2=0.23, p<0.01) and negligible in anti-VEGF studies (I2=7%, tau2=0.003, p=0.38). GRADE certainty was moderate for anti-VEGF and low for surgery. Anti-VEGF had lower rates of cataract (0% vs 4.6%), proliferative vitreoretinopathy (PVR, 0.1% vs 2.0%), and retinal detachment (RD, 0.1% vs 10.6%), but similar rates of recurrent hemorrhage (5.4% vs 5.3%). Complications were summarized descriptively due to zero cell problem. CONCLUSION: Both anti-VEGF and surgery treat SMH in AMD with similar VA outcomes but different safety profiles. Anti-VEGF is preferred for less severe hemorrhage, while surgery is suited for extensive hemorrhage. Despite uncertain comparative VA outcomes, treatment should be guided by clinical judgment and patient factors.
RESUMO
A 4-month-old girl was referred for evaluation of an anterior chamber cyst in the left eye. Examination under anesthesia (EUA) revealed a large iris stromal cyst in the anterior chamber involving the angle and the pupillary border, with touch of the corneal endothelium and anterior lens capsule. Intraocular pressure was normal. There was no anisometropic refractive error by retinoscopy. Close observation with amblyopia management was recommended as the pupil was only partially occluded by the cyst, and there was a clear red reflex around the cyst. Repeat EUA 6 months following diagnosis showed spontaneous collapse of the cyst. There was no recurrence noted at her most recent follow-up, 2 years after presentation, and most of the pupillary axis remains unobstructed by the cyst. The patient continues to be followed to monitor for possible cyst progression, anisometropia, and development of amblyopia. Though rare, spontaneous resolution of an iris stromal cyst may occur and thus, observation may be considered, particularly if the cyst is not causing anterior segment complications or obstruction of the visual axis.

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-ß 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.
