RESUMO
OBJECTIVE: To evaluate visual outcomes after switching from bevacizumab to ranibizumab or aflibercept in patients with macular edema (ME) secondary to branch retinal vein occlusion (BRVO). DESIGN: A retrospective, multi-center, observational study. PARTICIPANTS: Patients diagnosed with BRVO and were treated with at least 3 bevacizumab injections, before anti VEGF switch. METHODS: The follow-up period was 36 months, and the primary study outcomes assessed changes in best corrected visual acuity (BCVA) after anti VEGF switch. RESULTS: A total of 263 eyes of 263 patients with a mean age of 71.5 ± 11.2 years of which 50% were of male gender met the inclusion criteria. Of them, 175 eyes did not undergo switch, whereas 88 eyes underwent anti-VEGF switch. There was not a significant difference in mean age (pâ¯=â¯0.634) and gender (pâ¯=â¯0.269) between the groups. Baseline BCVA of the no-switch group was 0.47 ± 0.43 logMAR (20/59 Snellen) versus 0.6 ± 0.49 logMAR (20/79 Snellen) (pâ¯=â¯0.031) in the switch group, and at 36-months it was 0.41 ± 0.39 (20/51 Snellen) logMAR versus 0.54 ± 0.49 logMAR (20/69 Snellen) (pâ¯=â¯0.035), respectively. The difference between the rate of change in BCVA per year was insignificant between groups (pâ¯=â¯0.414). In multivariate analysis, baseline BCVA was the single significant predictor for switch (beta 0.137, pâ¯=â¯0.035). Patients with more than one anti-VEGF switch suffer from decrease in BCVA. CONCLUSIONS: Worse baseline BCVA is a significant predictor for anti-VEGF switch execution, though the switch has no significant impact on the change in BCVA over time. Multiple anti-VEGF switch is not recommended.
RESUMO
Background: We report the case of bilateral, subinternal limiting membrane crystalline deposits in a patient with Terson syndrome, describe the possible pathogenesis, and highlight management. Case Presentation. A 24-year-old male with a history of traumatic massive parenchymal and subdural frontal hemorrhage presented to our clinic seven months after a motor vehicle accident, prolonged hospitalization, and rehabilitation, complaining of decreased vision in both eyes. The Snellen visual acuity was 1/60 in the right eye, and 6/60 in the left eye. Fundus examination showed an organized white vitreous hemorrhage in both eyes with almost no view of the retina. The anterior segments were normal. He underwent a 25-gauge pars plana vitrectomy in both eyes. During the surgery, golden crescent-shaped sediment consisting of small crystals was observed under the internal limiting membrane in both eyes: anterior to the inferior temporal vascular arcade in the right eye and posterior to it in the left eye. Internal limiting membrane (ILM) peeling after staining with ILM-blue dye was performed in the left eye, where the finding involved the macula. One year after the surgery, visual acuity significantly improved to 6/8.5 on the right and 6/6 on the left. Epiretinal membrane formation was observed in the right eye, where ILM peeling was not performed. Conclusion: Subinternal limiting membrane crystalline deposit finding is a rare condition. Consider performing internal limiting membrane peeling and sediment removal in cases with macular involvement. In cases where crystals are concentrated outside of the macula, follow-up may be considered.
RESUMO
PURPOSE: To evaluate the impact of the changes in treatment patterns before, during and after the COVID-19 pandemic on best-corrected visual acuity (BCVA) in previously treated neovascular age-related macular degeneration (nAMD) patients. METHODS: A multi-centre, retrospective, observational study of consecutive nAMD patients during 2019-2021. Data collected included demographics, BCVA, dates of intravitreal anti-vascular endothelial growth factor (anti-VEGF) injections and clinic visits. RESULTS: A total of 1652 eyes of 1652 nAMD patients were included, out of which 850 eyes were assessed in 2019 (pre-COVID-19), 630 eyes were assessed in 2020 (COVID-19) and 974 eyes were assessed in 2021 (post-COVID-19). During the COVID-19 period, the mean number of anti-VEGF injections was significantly lower than the corresponding pre-COVID-19 and post-COVID-19 periods (5.55 compared to 6.13 and 6.60, respectively p < 0.01). A constant lower ratio of injections per patient/month was observed during COVID-19 compared to previous and following years, with a notable decline during March-April, reaching a ratio of 0.4 in 2020 versus 0.65 in 2019 and 0.62 in 2021 (p < 0.01). Baseline BCVA (0.825, p < 0.001), number of injections (-0.007, p < 0.001), gender (-0.027, p = 0.037) and age (0.004, p < 0.001) were shown to be significant predictors of final BCVA. CONCLUSION: During the COVID-19 period, patients were treated with significantly less intravitreal anti-VEGF injection compared to the previous year with compensation in the following year. These changes in treatment patterns did not have a significant impact on BCVA outcomes. Age, gender, baseline BCVA and number of injections are predictors of final visual outcomes.

PURPOSE: To assess the influence of iris color on the predisposition for intraoperative floppy iris syndrome (IFIS) during cataract surgery. METHODS: Medical records of patients who underwent cataract surgery in two medical centers between July 2019 and February 2020 were reviewed. Patients younger than 50 years, with preexisting ocular conditions affecting pupillary size or anterior chamber depth (ACD), and combined procedures were excluded. The remaining patients were questioned via telephone regarding their iris color. The association of IFIS occurrence and severity with iris color was tested using univariant and multivariant analyses. RESULTS: Overall, 155 eyes of 155 patients were included, 74 with documented IFIS and 81 without. The mean age was 74.03 ± 7.09 years, and 35.5% were female. The most common iris color among study eyes was brown (110/155, 70.97%), followed by blue (25/155, 16.13%) and green (20/155, 12.90%). Compared to brown-colored eyes, blue irises exhibited a 4.50-fold risk for IFIS (OR = 4.50, 95% CI: 1.73-11.70, p = 0.002), and green irises 7.00-fold risk (OR = 7.00, 95% CI: 2.19-22.39, p = 0.001). After adjusting for possible confounders, the results remained statistically significant (p < 0.01). Light-colored irises tended to exhibit a more severe IFIS compared to the brown iris group (p < 0.001). IFIS bilaterality was also affected by iris color (p < 0.001), with a 10.43-fold risk for fellow eye IFIS in the green iris group compared to eyes with brown irises (OR = 10.43, 95% CI: 3.35-32.54, p < 0.001). CONCLUSIONS: Light iris color was associated with a significantly increased risk of IFIS occurrence, severity, and bilaterality on univariate and multivariate analysis in this study.

INTRODUCTION: The objective of this study was to evaluate the impact of unplanned treatment gap, secondary to COVID-19 pandemic lockdowns, on visual acuity in previously treated diabetic macular edema (DME) patients. METHODS: A multicenter, retrospective study of DME patients, previously treated with anti-VEGF injections, who were followed up during COVID-19 pandemic (2020) compared to pre-CO-VID-19 period (2019). RESULTS: A total of 634 DME patients with a mean age of 68.4 years met the inclusion criteria, 385 were assessed in 2019 (pre-COVID-19) and 239 patients assessed in 2020 (COVID-19). Baseline best corrected visual acuity (BCVA) among patients in 2019 and 2020 was 0.52 ± 0.44, 0.45 ± 0.43 (logarithm of the minimal angle of resolution, respectively). There was no significant difference between the years 2020 and 2019 in baseline BCVA (p = 0.07). Mean number of anti-VEGF injections was significantly lower (5 vs. 6, p < 0.01), with a major lower ratio of injections per patient in the COVID-19 first lockdown period (March-June 2020) in the COVID-19 group. Baseline BCVA (p < 0.01) was the only significant predictor of final BCVA. Number of injections, age, gender, and the year were not found as predictors of final BCVA. CONCLUSIONS: In a large cohort of DME patients, an unplanned delay in treatment with anti-VEGF injections for 2-3 months, due to COVID-19 pandemic lockdown, had no significance impact on visual acuity. For most patients, returning to routine treatment regimen was sufficient for maintaining BCVA.

PURPOSE: To evaluate the impact of postponed care attributed to coronavirus disease (COVID-19) pandemic lockdowns on visual acuity and the number of anti-VEGF injections in patients with retinal vein occlusion (RVO). METHODS: A multicenter, retrospective study of consecutive RVO patients previously treated with anti-VEGF injections, which compared data from pre- (2019) and during (2020) COVID-19 lockdown period. RESULTS: A total of 814 RVO patients with a mean age of 72.8 years met the inclusion criteria. Of them, 439 patients were assessed in 2019 and 375 in 2020. There was no significant difference between the COVID-19 and pre-COVID-19 period in terms of baseline and final BCVA (p = 0.7 and 0.9 respectively), but there was a significantly reduced mean number of anti-VEGF injections during the COVID-19 period (5.0 and. 5.9 respectively, p < 0.01), with a constant lower ratio of injections per patient. A noticeable decline was found during March-May (p < 0.01) in 2020. Baseline BCVA (0.69, p < 0.01) and the number of injections (- 0.01, p = 0.01) were predictors of final BCVA. CONCLUSIONS: In a large cohort of RVO patients, during 2020 lockdowns imposed due to the COVID-19 pandemic, a significant reduction in the annual number of anti-VEGF injections was noted. The postponed care did not result in a significant impact on the final BCVA. Baseline BCVA and the number of annual injections serve as predictors for final BCVA in RVO patients.

PURPOSE: To assess the number of recruits for military service in the Israeli Defense Force (IDF) who underwent refractive surgery prior to enlistment and examine whether the procedure affected their ability to accomplish combat training. SETTING: Medical records of IDF recruits. DESIGN: Retrospective analysis of medical records of recruits with ametropia who underwent or did not undergo refractive surgery prior to enlistment. METHODS: Recruits were categorized into ametropes and recruits who underwent refractive surgery. Fitness and assignment to combat units and completion status of combat training were compared between the two groups. RESULTS: The study included 334,688 (182,969 males, 151,719 females) ametropes of which 5231 (4753 males, 478 females) underwent refractive surgery prior to recruitment. Refractive surgery prevalence increased from 9/1000 ametropes in 2005 to 18.5/1000 ametropes in 2018 (r = 0.912, p < 0.001); 2643 of the operated recruits (50.5%) had their surgery at the age of 17-18. Dropout rates from combat training were significantly lower in the refractive surgery group during the study period (1.68% vs. 6.14%, respectively, p < 0.001). Soldiers in the operated group were more frequently referred to ophthalmologists than those in the ametropes group and less frequently referred to optometrists. CONCLUSIONS: The prevalence of refractive surgery in IDF recruits has increased substantially during the last decade with more of them applying to combat units. Refractive surgery opened new possibilities for recruits who were unfit for combat duty prior to surgery and did not appear to impair the chances of successfully completing combat training.

OBJECTIVE: To report the long-term outcomes of anti-vascular endothelial growth factor (VEGF) treatment in eyes with peripapillary choroidal neovascularisation (PPCNV) associated with age-related macular degeneration (AMD). METHODS: A retrospective cohort study included patients with AMD-related PPCNV. Eyes were treated with anti-VEGF according to pro re nata regimen. Inactivation index was calculated as the proportion of disease inactivity from the total follow up time. RESULTS: Sixty-seven eyes of 66 consecutive patients were included in the study; mean follow-up time was 53.2 months. Best corrected visual acuity (BCVA) remained stable for the first four years of follow up, with a significant deterioration in BCVA thereafter. Baseline BCVA was a significant predictor of final BCVA (p < 0.001). The mean inactivation index was 0.38 ± 0.23. Subretinal fluid (SRF) at presentation was significantly associated with decreased inactivation index (p < 0.05). Worse baseline BCVA, SRF and pigment epithelium detachment (PED), male sex, and younger patient age were associated with increased risk for recurrence after first inactivation (p < 0.05). CONCLUSION: The use of anti-VEGF agents in the treatment of AMD-related PPCNV managed to preserve BCVA in the first four years of follow-up. Male sex, SRF and PED at presentation and baseline BCVA are associated with increased risk for PPCNV recurrence after the first inactivation, and should prompt careful follow-up in these patients.

PURPOSE: Evaluating the impact of delayed care, secondary to coronavirus disease 2019 (COVID-19) pandemic lockdowns, on visual acuity in previously treated neovascular age-related macular degeneration (nAMD) patients. METHODS: This was a multicenter, retrospective, study of patients with nAMD previously treated with anti-VEGF injections who were followed up during 2019 (pre-COVID-19) and compared with patients with nAMD during 2020 (COVID-19). RESULTS: A total of 1,192 patients with nAMD with a mean age of 81.5 years met the inclusion criteria. Of these, 850 patients were assessed in 2019 (pre-COVID-19) and 630 patients were assessed in 2020 (COVID-19). Three hundred eight patients were assessed through both 2019 and 2020 and thus were included in both cohorts. There was no significant difference between 2020 and 2019 in baseline and change in best-corrected visual acuity (BCVA; P = 0.342 and P = 0.911, respectively). The mean number of anti-VEGF injections was significantly lower (5.55 vs. 6.13, P < 0.01), with constant lower ratio of injections per patient in the COVID-19 period. Baseline BCVA (0.859, P < 0.01), number of injections (-0.006, P = 0.01), and age (0.003, P < 0.01) were predictors of final BCVA. CONCLUSION: In patients with nAMD, delayed care secondary to COVID-19 pandemic lockdowns has no statistically significant impact on BCVA. Best-corrected visual acuity, older age, and lower number of yearly anti-VEGF injections are predictors for decrease BCVA.

PURPOSE: To evaluate the outcome of pterygium surgery with conjunctival autograft using Vicryl sutures (Ethicon, NJ), Evicel fibrin glue (Omrix Biopharmaceuticals Ltd, Ramat-Gan, Israel), or Tisseel fibrin glue (Baxter Corp., Deerfield, IL). DESIGN: Prospective, randomized study. PARTICIPANTS: Eighty-nine adult patients with primary pterygium. METHODS: Patients undergoing pterygium surgery with conjunctival autografting were randomized into groups receiving 10-0 Vicryl sutures, Evicel fibrin glue, or Tisseel fibrin glue. MAIN OUTCOME MEASURES: Duration of surgery, level of patient discomfort, visual acuity (VA), surgically induced refractive change (SIRC), complications, and pterygium recurrence. RESULTS: Eighty-nine patients participated: 25 in the Vicryl group, 29 in the Evicel group, and 35 in the Tisseel group. The patients' preoperative characteristics were similar in all groups. Fashioning and repositioning of the conjunctival autograft (flap time) was significantly shorter in the fibrin glue groups compared with the Vicryl group: 5.46 minutes for Evicel, 3.6 minutes for Tisseel, and 16.72 minutes for sutures (P < 0.0001). The patient discomfort level during the first postoperative day was significantly lower in the fibrin glue groups compared with the suture group (P = 0.047). There were no significant group differences in the change in logarithm of the minimum angle of resolution VA before surgery and 3 months after surgery (P = 0.7). There were also no significant group differences in the SIRC (P = 0.108). The recurrence rate was 17.24% in the sutures group, 4.17% in the Evicel group, and 0% in the Tisseel group (P = 0.027 sutures vs. fibrin glue groups). Complications included 5 cases of conjunctival graft dislocation in the Evicel group, 1 case of pyogenic granuloma in the Tisseel group, and no complications in the sutures group (P = 0.019 sutures vs. fibrin glue groups). CONCLUSIONS: Tisseel fibrin glue for the repositioning of conjunctival autografts in pterygium surgery was associated with a similar functional outcome as that of Vicryl sutures in terms of VA and SIRC. Pterygium recurrence, patient discomfort level, and surgery time were reduced markedly, as were flap dislocation and pterygium recurrence with Tisseel fibrin glue compared with Evicel fibrin glue.

This clinical case report describes a patient diagnosed with severe to moderate intellectual disability with autistic tendencies, resident in a home for adults with a range of disabilities. She had been resident for 18 years prior to intervention by the author when she was 48 years of age. The author worked with her from June 25, 2013 until January 12, 2015 for a total of 55 Waldon Approach (1), movement-based lessons each of about 45 min of which 33 were documented by video. This report describes changes in her cognition and her social behavior at a time when there were no other changes in her life. As far as the author is aware, this is the first clinical case report on the Waldon Approach to appear in a peer-reviewed journal and is unique in that most of the work using the approach is with children who are usually receiving other therapies at the same time as their Waldon Lessons, making it harder to evaluate the attribution of change. During the period of this report, she received no other therapy or intervention beyond that provided at Maon Roglit, which itself had not changed during this period. The patient remains without speech, but there has been real, meaningful, and noticeable change in her life from which she appears to derive pleasure. There has been a significant improvement in the patient's group participation, facial expression, and general demeanor.
