RESUMEN
PURPOSE: This study aimed to evaluate the efficacy and clinical outcomes of a one-way fluid-air exchange procedure for the treatment of postvitrectomy diabetic vitreous hemorrhage in patients with proliferative diabetic retinopathy. METHODS: This retrospective study included 233 patients with proliferative diabetic retinopathy, who underwent vitrectomy. A one-way fluid-air exchange procedure was performed in 24 eyes of 24 (10.30%) patients with persistent vitreous cavity rebleeding after the operation. Preprocedural and postprocedural best-corrected visual acuity values were achieved. Complications occurring during and after the procedure were analyzed. RESULTS: Significant visual improvement was observed 1 month after the one-way fluid-air exchange procedure (2.62 ± 0.60 LogMAR at baseline vs. 0.85 ± 0.94 LogMAR at postprocedure, p<0.0001). Moreover, 19 (79.17%) eyes needed the procedure once, and 5 (20.83%) eyed had the procedure more than twice. In 3 (12.50%) eyes, reoperation was eventually required because of persistent rebleeding despite several fluid-air exchanges. No complication was observed during the follow-up. CONCLUSIONS: The one-way fluid-air exchange procedure can be an excellent alternative to re-vitrectomy for patients with proliferative diabetic retinopathy suffering from postvitrectomy diabetic vitreous hemorrhage by removing the hemorrhagic contents directly and achieving fast recovery of visual function without apparent complications.

RESUMEN
ABSTRACT Purpose: To evaluate the effects of suturing 23-gauge pars plana vitrectomies on ocular discomfort and tear film dynamics. Methods: This retrospective chart review involved data from 50 procedures in 50 patients who underwent 23-gauge pars plana vitrectomy from January to November 2016. We divided the eyes into two groups according to the presence or absence of sutures; 35 eyes underwent sutureless vitrectomies (Group 1), and 15 eyes underwent vitrectomy with at least one sclerotomy suture site (Group 2). In each group, we assessed objective variables including tear film break-up time, Schirmer test I, corneal surface grading with Oxford system, and a quantitative method evaluating subjective dry eye symptoms using ocular surface disease index questionnaires preoperatively 1 week, and 1 and 3 months after surgery. Results: The tear film break-up time showed a significant difference at the 3-months follow-up (p=0.026). The Schirmer test I and corneal surface staining score showed no statistically significant differences between two groups at any time after the operations. The ocular surface disease index score was significantly lower in Group 1 than in Group 2 at 1 week (p=0.032), 1 month (p=0.026), and 3 months (p=0.041) after the operation. Conclusion: Sclerotomy suturing caused ocular discomfort and had a negative effect on tear film dynamics during the late postoperative period. Sclerotomies without suturing seem to reduce the ocular surface changes.
RESUMO Objetivo: Avaliar os efeitos da sutura da vitrectomia via pars plana de 23-gauge sobre o desconforto ocular e a dinâmica do filme lacrimal. Métodos: Esta revisão retrospectiva de prontuários envolveu dados de 50 casos em 50 pacientes submetidos à vitrectomia via pars plana de 23-gauge, de janeiro a novembro de 2016. Dividimos os olhos em dois grupos de acordo com a presença ou ausência de suturas; 35 olhos foram submetidos à vitrectomia sem sutura (Grupo 1) e 15 olhos foram submetidos à vitrectomia com pelo menos um ponto de sutura no local da esclerotomia (Grupo 2). Em cada grupo, avaliamos variáveis objetivas incluindo tempo de ruptura do filme lacrimal, teste de Schirmer I, gradação da superfície corneana com o sistema Oxford e um método quantitativo avaliando sintomas subjetivos de olho seco usando questionários de índice de doença da superfície ocular nos períodos: 1 semana do pré-operatório, 1 mês e 3 meses após a cirurgia. Resultados: O tempo de ruptura do filme lacrimal apresentou diferença significativa no seguimento de 3 meses (p=0,026). O teste de Schirmer I e o escore da coloração da superfície da córnea não mostraram diferenças estatisticamente significativas entre os dois grupos em nenhum momento após as operações. O escore do índice de doença da superfície ocular foi significativamente menor no Grupo 1 em relação ao Grupo 2 no período de 1 semana (p=0,032), 1 mês (p=0,026) e 3 meses (p=0,041) após a cirurgia. Conclusão: A sutura da esclerotomia causou desconforto ocular e teve um efeito negativo na dinâmica do filme lacrimal durante o período pós-operatório. Esclerotomias sem sutura parecem reduzir as alterações da superfície ocular.
