Vitreous block (VB), a rare secondary angle-closure caused by anterior rotation of the ciliary body, occurs in a variety of settings, but most frequently after glaucoma filtering surgery. The etiology remains unclear, but choroidal expansion and anterior vitreous abnormalities have been proposed. In the past, treatment of VB has yielded high rates of failure and recurrence. Advancements in surgical techniques, however, have led to improved visual outcomes. We review the history of this condition and present a stepwise approach to its diagnosis and treatment using modern imaging modalities and surgical techniques.
玻璃体阻断(VB)是一种由睫状体前旋引起的罕见的继发性闭角型青光眼,发生在多种情况下,但最常发生在青光眼滤过手术后。病因尚不清楚,但有人提出脉络膜扩张和玻璃体前异常。过去,VB 的治疗成功率和复发率都很高。然而,手术技术的进步导致了更好的视力结果。我们回顾了这种疾病的历史,并使用现代成像方式和手术技术提出了一种逐步的诊断和治疗方法。
