Abstract
Objetivo: Avaliar os possíveis fatores relacionados à formação de fibrina na câmara anterior após cirurgia vitreorretiniana em uma grande série de casos. Métodos: Foi realizado um estudo retrospectivo, observacional, caso-controle, onde os dados de 185 olhos de 185 pacientes submetidos à cirurgia vitreorretiniana foram avaliados. Os seguintes dados foram analisados: presença ou não de fibrina na câmara anterior na primeira semana de pós-operatório, idade, presença ou não de diabetes mellitus, calibre do sistema de vitrectomia utilizado (20,23 ou 25 gauge), [...]
Highlights
RESULTSInflammatory reaction of the anterior segment associated with alterations of the blood-aqueous barrier are common events in the postoperative period of intraocular eye surgery[1]
The incidence of anterior chamber fibrin formation is estimated around 2% after cataract extraction and intraocular lens implantation[3], but with the advent of modern smallincision cataract surgery, it is probable that this incidence is much lower nowadays
The presence of anterior chamber fibrin formation was considered as the dependent variable, whereas patient’s age, presence of diabetes, the vitrectomy system gauge, the type of vitreous substitute and the association with cataract surgery were considered as independent variables
Summary
Inflammatory reaction of the anterior segment associated with alterations of the blood-aqueous barrier are common events in the postoperative period of intraocular eye surgery[1]. These events are usually managed with the use of topical anti-inflammatory medication for a few days or weeks. The occurrence of anterior chamber fibrin reaction after vitreoretinal surgery is an important complication, especially because of posterior segment visualization impairment. The aim of this study was to investigate possible predictive factors associated with the formation of fibrin in the anterior chamber in patients submitted to vitreoretinal surgery
