Pigmentary glaucoma is a common secondary glaucoma that results from pigment being liberated from the posterior iris with subsequent buildup in the trabecular mesh-work. Following this, there is a decrease in aqueous outflow and resultant rise in intraocular pressure.
While this presentation typically occurs in white myopic males, there is a distinct subtype that occurs in patients of African descent. While there are similarities between the races, there are also significant differences in the clinical presentation of pigmentary glaucoma in white patients and patients of African descent. Iris transillumination defects, corneal endothelial pigment accumulation, and a concave iris-common in whites-are typically absent in patients of African descent.
The literature is reviewed in order to summarize pigment dispersion syndrome and pigmentary glaucoma.
色素性青光眼是一种常见的继发性青光眼，其病因是色素从虹膜后表面释放出来，随后在小梁网中积聚。在此之后，房水流出减少，导致眼压升高。
虽然这种表现通常发生在白人近视男性中，但有一种独特的亚型发生在非洲裔患者中。虽然不同种族之间存在相似之处，但白人患者和非洲裔患者色素性青光眼的临床表现也存在显著差异。虹膜透照缺损、角膜内皮色素沉着以及白人中常见的虹膜凹陷在非洲裔患者中通常不存在。
对文献进行综述，以总结色素播散综合征和色素性青光眼。
