ABSTRACT
BACKGROUND: The epiretinal membrane (ERM) is a nonvascular fibrocellular tissue formed by cellular metaplasia and proliferation at the vitreoretinal surface and is generally treated by pars plana vitrectomy (PPV) with or without internal limiting membrane (ILM) peeling. This network meta-analysis aimed to compare the efficacy of all available ERM removal interventions and assessed the use and efficacy of surgical dyes in managing idiopathic ERMs. METHODS: MEDLINE, EMBASE, Cochrane CENTRAL, and the US National Library of Medicine were searched (June 28, 2023). Clinical studies that included patients with ERMs were included. Randomized controlled trials (RCTs) were also appraised using Cochrane risk of bias (ROB). RESULTS: Ten RCTs and ten non-RCTs were included in this study. A pairwise meta-analysis between ERM removal and combined ERM and ILM removal showed no significant difference in visual outcome (change in BCVA) 1 year postintervention (MD = - 0.0034, SE = 0.16, p = 0.832). Similarly, there was no significant difference in the central macular thickness postoperatively between the two groups (MD = - 4.95, SE = 11.11, p = 0.656) (Q = 4.85, df = 3, p = 0.182, I2 = 41.21%). The difference in ERM recurrence between the groups was also not statistically significant (OR = 4.64, p = 0.062, I2 = 0). In a network meta-analysis, there was no significant difference in visual outcomes between ERM removal only and other treatment modalities: combined ILM and ERM removal (MD = 0.039, p = 0.837) or watchful waiting (MD = 0.020, p = 0.550). In a network meta-analysis, there was no significant difference in the visual outcomes between ERM removal alone and dye-stained combined ERM and ILM peeling (MD = 0.122, p = 0.742 for brilliant blue G; BBG and MD = 0.00, p = 1.00 for membrane blue-dual; MBD). The probability of being a better surgical dye for better visual outcomes was 0.539 for the MBD group and 0.396 for the BBG group. The recurrence of ERM was not significantly different when the ILM was stained with any of the dyes. No study was judged on ROB assessment as having low ROB in all seven domains. CONCLUSION: The two types of surgical modalities provided comparable efficacy, with no significant differences between the outcomes. Among the dye-assisted ILM peeling methods, the membrane blue-dual dye was the most effective in providing better structural and functional outcomes.
ABSTRACT
INTRODUCTION: Diabetic macular edema (DME) is one of the leading causes of vision impairment. The relationship between DME and estimated glomerular filtration rate (eGFR) has not been clearly evaluated in Hispanic or Latino populations. The objective of this study was to evaluate the eGFR in a Latino population with DME. METHODS: A cross-sectional, observational, and descriptive study was carried out on the basis of a multicenter phase III clinical trial. RESULTS: A total of 82 subjects diagnosed with DME (36 women and 46 men) were included in the study. The mean age was 61.93 ± 6.71 years. Mean values of the blood chemistry parameters glycated hemoglobin and eGFR were 7.20 ± 0.95% and 74.42 ± 26.82 mL/min/1.73 m2, respectively. The time elapsed since diagnosis of diabetes mellitus was 15.30 ± 7.35 years, while the duration of DME was 1.41 ± 1.75 years. Mean values for central macular thickness (CMT) and total macular volume (TMV) were 440.99 ± 132.22 µm and 11.97 ± 2.11 mm3, respectively. DME duration had a negative correlation with TMV (Rho - 0.26, p < 0.05) and a positive correlation with mean arterial pressure (Rho 0.26, p < 0.05). CMT was correlated with TMV (Rho 0.43, p < 0.0001) and visual acuity (Rho 0.26, p < 0.05). No significant correlations were observed between eGFR and CMT, TMV, or any demographic variable (p > 0.05). Chronic kidney disease (CKD) was associated with hypertension (OR 9.32, p = 0.035), elevated intraocular pressure (IOP) (OR 0.03, p = 0.011), and advanced age (OR 0.45, p = 0.011). CMT was significantly associated with TMV (ß = 27.69, p < 0.0001). CONCLUSIONS: We did not find a correlation between eGFR and DME. Our findings suggest that the presence of hypertension is associated with a decrease in the GFR < 60 mL/min/1.73 m2, and CKD may be associated with advanced age and elevated IOP which may increase the risk for the development of glaucoma.

ABSTRACT
Objetivo: estudiar en nuestro entorno la prevalencia de la enfermedad vascular retiniana y su caracterización clínica y epidemiológica. Métodos: se realizó un estudio descriptivo, longitudinal y prospectivo en una consulta del Servicio de Vítreo-Retina del Instituto Cubano de Oftalmología "Ramón Pando Ferrer", durante el período de enero del año 2015 a noviembre de 2016. Se caracterizaron los aspectos clínicos y epidemiológicos en 52 ojos de 49 pacientes diagnosticados con oclusión venosa retiniana. Resultados: en la serie predominaron los grupos etarios mayores de 55 años, la raza blanca y no hubo predilección por sexo. Fueron más frecuentes la oclusión de la vena central de la retina, las formas isquémicas de daño vascular, la hipertensión arterial, la diabetes mellitus y el glaucoma de ángulo abierto como factores de riesgo asociados. El edema macular secundario a oclusión venosa retiniana fue la principal complicación. Conclusión: las afecciones sistémicas, como la hipertensión arterial, la diabetes mellitus, la hipercolesterolemia, el accidente cerebrovascular, la hiperviscosidad sanguínea y la trombofilia son fundamentales en el desarrollo de dicha afección vascular, así como los factores de riesgo oftálmicos como la hipertensión ocular, el glaucoma, la presión de perfusión ocular disminuida, los cambios adquiridos en las arterias retinales y los hábitos tóxicos relevantes(AU)
Objective: review and study the prevalence of retinal vascular disease in our environment and its clinical and epidemiological characterization. Methods: a prospective, longitudinal descriptive study was conducted at a consultation office of the Vitreous-Retina Service of Ramón Pando Ferrer Cuban Institute of Ophthalmology from January 2015 to November 2016. Clinical and epidemiological characterization was performed of 52 eyes of 49 patients diagnosed with retinal vein occlusion. Results: in the series there was a predominance of the over-55-years age groups and the white race. Neither sex prevailed. The most frequent disorders were central retinal vein occlusion, ischemic forms of vascular damage, arterial hypertension, diabetes mellitus and open angle glaucoma as associated risk factors. The main complication was macular edema secondary to retinal vein occlusion. Conclusion: systemic disorders such as arterial hypertension, diabetes mellitus, hypercholesterolemia, cerebrovascular accident, blood hyperviscosity and thrombophilia, are crucial to the development of the study vascular condition, alongside ophthalmic risk factors such as ocular hypertension, glaucoma, reduced ocular perfusion pressure, acquired changes in retinal arteries, and relevant toxic habits(AU)
