BackgroundCalcified band keratopathy is a chronic degenerative disease characterized by the deposition of gray to white opacity in superficial layers of the cornea that typically develops over months or years. It is associated with a variety of conditions, including chronic uveitis.PurposeThe objective of this study is to assess visual acuity and corneal changes in patients with band keratopathy secondary to uveitis who underwent phototherapeutic keratectomy (PTK).SettingThe place where this study was performed was in the Department of Ophthalmology and Visual Sciences, Federal University of Sao Paulo.DesignThis is a retrospective study.MethodsPatients with uveitic band keratopathy were submitted to PTK. The PTK was performed using Allegreto Wave EX500, with the ablation area of 6 mm.ResultsTwelve patients (13 eyes) diagnosed with band keratopathy secondary to chronic uveitis were analyzed. Of the 12 patients, 8 patients were female (66 %), aged 22 years (7–53 years). From the 12 patients (13 eyes) evaluated in this study, only one patient (one eye) did not have visual improvement, due to epithelial deposits 2 weeks after PTK, and all the others benefited with the procedure. In the children group, all eyes had visual improvement, and quantitatively speaking, the children had a more significant improvement than adults.ConclusionsPTK is a safe and effective procedure even for children. However, the improvement in visual acuity was restricted due to other ocular changes secondary to uveitis, such as cataract and retinal changes, or even the corneal irregularity.
O termo uveíte refere-se à inflamação no trato uveal ocular, que envolve íris, corpo ciliar e coroide (Figura 1). As uveítes são classificadas de acordo com o sítio primário de inflamação, início (súbito ou insidioso), duração (limitada ou persistente, quando apresenta duração maior que três meses), curso clínico (agudo, recorrente ou crônico, quando possui duração de mais de três meses ou recidiva em menos de três meses após interrupção do tratamento), uni ou bilateralidade e etiologia. A classificação anatômica divide as uveítes em anterior, intermediária, posterior e panuveíte. Na uveíte anterior, o sítio primário de inflamação é a câmara anterior, como irites, ciclites (inflamação do corpo ciliar), iridociclites. Na uveíte intermediária, o sítio primário de inflamação é o vítreo (pars planite). Na uveíte posterior, o sítio primário é a coroide e/ou retina (coroidite multifocal, focal ou difusa, retinite, retinocoroidite, neurorretinite e vasculite retiniana). Já nas panuveítes, a inflamação envolve câmara anterior, vítreo, retina e coroide, como, a síndrome de Vogt Koyanagi Harada. Neste artigo serão estudadas as uveítes mais relacionadas com doenças reumatológicas: uveítes anteriores e vasculites retinianas.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
