Resumo: | INTRODUCTION: The relationship between early and late postoperative intraocular pres- sure (IOP) after glaucoma surgery remains unclarified. Few published studies have investigated the long-term effects of early IOP after trabeculectomy and nonpenetrating deep sclerectomy, and the existing ones have differing results. This study aims to evaluate the effects of early postoperative IOP after these two procedures on long-term surgical success rate. METHODS: We retrospectively studied the patients with open-angle glaucoma who underwent primary trabeculectomy (86 eyes of 72 patients) or primary nonpenetrating deep sclerectomy (137 eyes of 117 patients) between January 2010 and July 2020 that were followed for at least 24 months postoperatively. For each procedure, the study population was divided into three groups according to the IOP registered in the early postoperative time: IOP <6 mmHg, IOP 6-18 mmHg and IOP >18 mmHg. The postoperative IOP, the number of IOP-lowering medications and best corrected visual acuity were compared among the groups. Surgical success was defined as presenting postoperative IOP ≤18 mmHg during medium and long-term follow-up period. Success probability analysis was performed using a Kaplan-Meier survival curve. RESULTS: Patients with an early IOP >18 mmHg had significantly worse IOP control and success rate in long-term follow-up for both trabeculectomy and nonpenetrating deep sclerectomy. Patients with early transient hypotony after trabeculectomy had a tendency for better long-term surgical outcome. CONCLUSION: The early postoperative IOP state influences the long-term prognosis after glaucoma surgery. |

Poucos estudos investigaram os efeitos a longo-prazo da PIO inicial após trabeculectomia ou esclerectomia profunda não penetrante, apresentando resultados contraditórios. Este estudo tem como objetivo avaliar os efeitos da PIO pós-operatória precoce na taxa de sucesso cirúrgico a longo-prazo após as duas técnicas cirúrgicas referidas. MÉTODOS: Estudo retrospetivo dos doentes com diagnóstico de glaucoma de ângulo aberto submetidos a trabeculectomia (86 olhos de 72 doentes) ou esclerectomia profunda não-penetrante (137 olhos de 117 doentes) como procedimento primário entre Janeiro de 2010 e Julho de 2020, que foram seguidos pelo menos 24 meses após a cirurgia. Para cada um dos procedimentos, a amostra foi dividida em três grupos de acordo com a PIO registada no período pós-operatório precoce: PIO <6 mmHg, PIO 6-18 mmHg e PIO >18 mmHg. A PIO, o número de fármacos antiglaucomatosos e a melhor acuidade visual corrigida pós-operatórios foram comparados entre grupos. Sucesso cirúrgico foi definido como PIO pós-operatória ≤18 mmHg ao longo do seguimento a médio e longo-prazo. A análise da probabilidade de sucesso cirúrgico foi realizada através da curva de sobrevivência de Kaplan-Meier. RESULTADOS: Doentes com PIO precoce >18 mmHg após trabeculectomia e esclerectomia profunda não-penetrante apresentaram um controlo da PIO e taxa de sucesso cirúrgico significativamente piores a longo-prazo. Doentes com hipotonia transitória precoce após trabeculectomia apresentaram uma tendência para resultados cirúrgicos mais favoráveis a longo-prazo. CONCLUSÃO: A PIO pós-operatória inicial influencia o prognóstico a longo-prazo após cirurgia de glaucoma.Ajnet2023-09-28info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://doi.org/10.48560/rspo.28279eng1646-69501646-6950Viana, Ana RitaBasto, RitaCorreia Barbosa, RenatoSilva, AlexandreBastos, RicardoVale, CarolinaGonçalves, RitaTenedório, Paulainfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2023-10-05T20:30:22Zoai:ojs.revistas.rcaap.pt:article/28279Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T20:33:27.202580Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
