RESUMO
PURPOSE: The purpose is to assess the effect of ethnicity on surgical macular hole closure. METHODS: A retrospective cohort study was undertaken in five UK National Health Service Hospitals. We included all patients with known ethnicity undergoing vitrectomy, internal limiting membrane peel, and gas/oil tamponade for all stages of primary full-thickness macular hole (FTMH). The primary outcome was anatomic success, defined as FTMH closure with one operation. The secondary outcome was mean change in best-corrected visual acuity (BCVA) comparing baseline with final review. RESULTS: Of 334 operations, the ethnicity profile comprised 78.7% White patients, 11.7% Black patients, 8.1% Asian patients, and 1.5% in mixed/other ethnicities. Mean age was 69.7 years with 68.5% females. Overall, 280 (83.8%) had anatomic success. Anatomic failure occurred in 38.5% of Black patients versus 12.6% of White patients (relative risk: 1.788; 95% CI: 1.012 to 3.159; P = 0.045). Overall, baseline logarithm of the minimum angle of resolution BCVA improved by 0.34, from 0.95 (95% CI: 0.894 to 1.008) to 0.62 (95% CI: 0.556 to 0.676). Mean BCVA improved by 0.35 in White patients, 0.37 in Black patients, 0.23 in Asian patients, and 0.38 in mixed/other ethnicity (P = 0.689). Greater FTMH minimum linear diameter was associated with an increased risk of anatomic failure (relative risk: 1.004; 95% CI: 1.002 to 1.005; P < 0.0001), whereas better pre-operative BCVA (F [1,19] = 162.90; P < 0.0001) and anatomic success (F [1,19] = 97.69; P < 0.0001) were associated with greater BCVA improvement. Socio-economic status did not significantly influence anatomic success or BCVA change. CONCLUSIONS: Black ethnicity is associated with an approximately twofold greater risk of failed FTMH surgery. The reasons for this difference warrant further study.

PURPOSE: retinal vein occlusion (RVO) is classified as either branch (BRVO) or central (CRVO) RVO. The gold standard treatment for macular oedema (MO) secondary to RVO is intravitreal anti-vascular endothelial growth factor (anti-VEGF) injections. Our study aimed to compare ranibizumab and aflibercept outcomes over a maximum follow-up of five years. METHODS: this retrospective study assessed treatment-naïve RVO patients. Active disease was treated with three loading injections followed by a pro-re-nata (PRN) regimen of an anti-VEGF agent. Visual outcomes and injection frequency were analyzed, with patients stratified according to RVO subtype, anti-VEGF agent used, baseline vision, and age. RESULTS: 316 CRVO-affected eyes and 467 BRVO-affected eyes were analysed. Visual benefits between different treatments did not significantly differ, except in year 1 in ranibizumab-treated BRVO eyes. However, aflibercept-treated CRVO and BRVO eyes required significantly fewer injections during the follow up period. Furthermore, our results confirm that younger patients achieve better visual outcomes with fewer intravitreal injections. Overall, half of our patients did not require further injections after 1 year from diagnosis. CONCLUSION: the results demonstrate that anti-VEGF treatment of RVO benefits vision for up to 5 years. Our findings are the first to suggest that compared to ranibizumab, fewer aflibercept injections may be required over five years follow up. Prospective randomised trials are needed to confirm this, alongside further attention to OCT scan features and the effect of patient demographics on treatment outcomes.

PURPOSE: To evaluate the long-term success rate of vitreoretinal surgery for severe cases of retinal capillary hemangiomas (RCHs) caused by von Hippel-Lindau (VHL) disease. DESIGN: Retrospective case series. PARTICIPANTS: Twenty-three eyes of 21 patients with severe exudative or tractional retinal detachment caused by RCH, who had undergone vitreoretinal surgery. Patients' age at initial surgery ranged from 12 to 47 years (median, 27 years), and the fellow eye was already blind in 6 of 21 patients. INTERVENTIONS: All eyes underwent pars plana vitrectomy with posterior hyaloid detachment epiretinal membrane dissection and silicone oil or gas injection. In 9 eyes, retinectomy was performed to remove the RCH (group R). In the other 14 eyes, the RCH was treated by laser endophotocoagulation alone or combined with transscleral cryotherapy (group L). MAIN OUTCOME MEASURES: Visual acuity (preoperative, 6 and 18 months postoperatively), rate of RCH recurrence, and postoperative complications. RESULTS: In group R, an average of 2 operations per patient was needed. Six months after surgery, the retina was flat in 8 eyes. Mean follow-up was 8 years. Long-term complications included RCH reproliferation and neovascular glaucoma in 4 eyes, 4 to 8 years after initial surgery. In the remaining 5 eyes, visual acuity ranged from 20/320 to counting fingers 18 months postoperatively. In group L, an average of 1.7 operations was needed. Six months after surgery, the retina was flat in 13 of 14 eyes. Mean follow-up was 4 years. New RCH occurred in 10 eyes and required laser treatment. In the long term, 1 eye became blind after 5 years because of aggressive RCH reproliferation and neovascular glaucoma, and 2 eyes became blind after 10 years because of exudative retinal detachment. In the 11 remaining eyes, visual acuity ranged from 20/320 to 20/20 (median: 20/50) 18 months postoperatively. CONCLUSIONS: Vitreoretinal surgery is an effective treatment for severe VHL retinal hemangiomas. Large RCHs were satisfactorily treated by (1) vitrectomy with epiretinal dissection and endolaser photocoagulation or (2) retinectomy for RCH resection, although a high rate of vision-threatening RCH recurrence was observed in the long term. However in most cases, surgery improved or prolonged visual function in these eyes.

PURPOSE: To investigate patient's perception of the severity of their symptoms, reasons for attending an ophthalmic emergency department (ED) out of hours, and to review the prevalence of anxiety and depression. METHODS: We carried out a prospective analysis of the cases presenting out of hours (8:30 PM to 8:30 AM) over a four-month period. We also conducted two questionnaire studies. First, patient's perception of the severity of their symptoms (graded from 1-10). A score of 7 or above was defined as significant. A second questionnaire study used the Hospital Anxiety and Depression Scale (HADS), with a maximum score of 21. Patients who scored between 7-10 points on either anxiety or depression scales are defined as borderline; above 10 as pathological. RESULTS: A total of 1,531 patients attended the out-of-hours service. The most common diagnoses were trauma (22.8%), infective conjunctivitis (10.2%), and contact-lens-related problems (6.6%). Of 175 completed questionnaires, worry about sight impairment and pain were the most common concerns for attendance. A total of 91% of patients believed their conditions were emergencies that require medical review within 24 hours. 127 HADS questionnaires were completed, showing that 18.9% and 15.0% of patients were suffering from borderline and pathological anxiety, respectively, with a mean HADS-A score of 6.5, SD=3.9. The prevalence of possible and pathological depression was 14.2% and 6.3%, mean=4.9 (SD=3.6). There was no statistical significance difference of score with the time of patient presentation. CONCLUSION: The prevalence of anxiety and depression is relatively high in patients who attended the ophthalmic ED and awareness of psychological impact should be raised amongst healthcare professionals.

PURPOSE: To report the use of optical coherence tomography (OCT) for evaluation of diffuse diabetic macular edema (DME) before and after vitrectomy. DESIGN: Interventional case series. METHODS: A retrospective study was made of 15 consecutive eyes of 13 patients that had vitrectomy for diffuse DME and OCT preoperatively and postoperatively. In seven eyes of six patients (group 1), vitrectomy was performed because of vitreomacular traction observed on biomicroscopy or OCT. In the other eight eyes of seven patients (group 2), vitrectomy was performed for DME not responsive to laser photocoagulation, with no vitreomacular traction on biomicroscopy or OCT. RESULTS: Mean +/- standard deviation (SD) follow-up after vitrectomy was 18 +/- 10 months (range, 6 to 33 months). In group 1, mean +/- SD retinal thickness decreased significantly from 661 +/- 181 microm preoperatively to 210 +/- 32 microm at the end of follow-up (P =.018). Median best-corrected visual acuity (BCVA) improved from 20/100 before surgery (range, 20/250 to 20/50) to 20/80 at the end of follow-up (range, 20/250 to 20/25; P =.046). In one eye in group 1, vitreomacular traction was only observed on OCT and not on biomicroscopy. In group 2, mean +/- SD retinal thickness decreased from 522 +/- 103 microm preoperatively to 428 +/- 121 microm at the end of follow-up (P =.2). Median BCVA was 20/100 before vitrectomy (range, 20/320 to 20/63) and 20/200 at the end of follow-up (range, 20/250 to 20/63; P =.78). CONCLUSIONS: Vitrectomy was beneficial in eyes with diffuse DME combined with vitreomacular traction but not in eyes without traction. Optical coherence tomography allowed diagnosis of subtle vitreomacular traction and provided precise preoperative and postoperative assessments of macular thickness.
