To report annular and central heavy pigment deposition on the posterior lens capsule in a case of pigment dispersion syndrome.
Case report.
A 36-year-old female with bilateral pigment dispersion syndrome presented with progressive decrease in visual acuity in the right eye over the past 1-2 years. Clinical examination revealed the typical findings of pigment dispersion syndrome including bilateral Krunkenberg spindles, iris transillumination defects, and dense trabecular meshwork pigmentation. Remarkably, annular and central dense pigmentation of the posterior lens capsule was noted in the right eye.
Annular pigment deposition on the posterior lens capsule may be a rare finding associated with pigment dispersion syndrome. Such a finding suggests that there may be aqueous flow into the retrolental space in some patients with this condition. The way of central pigmentation is the entrance of aqueous to Berger's space. In our case, it is probable that spontaneous detachment of the anterior hyaloid membrane aided this entrance.
报告一例色素性分散综合征患者后囊膜出现环状及中央重度色素沉着的情况。
病例报告。
一名36岁双侧色素性分散综合征女性患者，在过去1至2年中右眼视力逐渐下降。临床检查发现色素性分散综合征的典型表现，包括双侧克伦伯格梭形色素沉着、虹膜透照缺损以及小梁网色素沉着浓密。值得注意的是，右眼后囊膜出现环状及中央浓密色素沉着。
后囊膜环状色素沉着可能是与色素性分散综合征相关的罕见表现。这一发现提示在部分患有该疾病的患者中，可能存在房水流入晶状体后间隙的情况。中央色素沉着的方式是房水进入伯杰间隙的入口。在我们的病例中，前玻璃体膜的自发脱离可能有助于房水的这种进入。
