Abstract We reported a case of ocular hypotony due to spontaneous scleral rupture in retinochoroidal coloboma and the treatment which was performed. This is a prospective case report in which a 21-year-old woman complained of abrupt vision loss in her left eye. Ocular hypotony due to spontaneous scleral rupture in retinochoroidal coloboma was identified through tests. An ultrassonography confirmed the scleral lesion but magnetic resonance imaging and fluorescein angiography have also proven to be useful. Due to the posterior location […]

Blunt eye trauma can generate a wide range of intraocular lesions that are dependent on the amount of energy the object transfers to the eye during the impact. Lesions of the iris, trabecular meshwork and ciliary body may influence aqueous humor drainage. The cyclodialysis which is characterized by the detachment of ciliary body from the scleral wall, creating a communication between the anterior chamber to supracoroid space, can cause a several reduction of intraocular pressure. This pressure decrease is responsible […]

PURPOSE: To report on a new treatment for hyperfiltering bleb as well as its diagnostic criteria. METHODS: Twenty eyes with hypotony due to hyperfiltering bleb caused by trabeculectomy with mitomicin C were treated with bleb resection. The diagnosis of hyperfiltering bleb followed these criteria: intraocular pressure lower than six mmHg (Goldmann tonometer); no inflammation in the anterior segment; presence of an elevated and/or diffuse and avascular bleb with or without microcysts; negative Seidel test; no ciliochoroidal detachment found with ultrasound […]

OBJETIVO: Relatar os resultados de uma nova técnica para o tratamento de bolsa hiperfuncionante, assim como seus critérios diagnósticos. MÉTODOS: Vinte olhos (20 pacientes) com hipotonia ocular causada por bolsa hiperfuncionante após trabeculectomia com mitomicina C foram tratados com ressecção da bolsa. O diagnóstico de bolsa hiperfuncionante obedeceu aos seguintes critérios: pressão intraocular inferior a seis mmHg (tonometria de Goldmann); ausência de inflamação do segmento anterior ocular; presença de bolsa fistulante elevada e/ou difusa e avascular com ou sem microcistos; […]
