PURPOSE
To report an unusual case of pigment dispersion syndrome associated with unilateral dense pigmentation of the posterior lens capsule.
METHODS
Case report.
RESULTS
A 59-year-old male with bilateral pigment dispersion syndrome presented with progressive decrease in visual acuity in the left eye over the past 10 to 20 years. Clinical examination revealed the typical findings of pigment dispersion syndrome including the presence of bilateral Krunkenberg spindles, iris transillumination defects, and heavy trabecular meshwork pigmentation. Of note, there was remarkably dense pigmentation of the posterior lens capsule in the eye with decreased visual acuity.
CONCLUSION
Pigmentation of 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 optimal treatment of this unusual condition remains undetermined.
目的
报告一例与单侧晶状体后囊致密色素沉着相关的色素播散综合征罕见病例。
方法
病例报告。
结果
一名患有双侧色素播散综合征的59岁男性，在过去10至20年中左眼视力逐渐下降。临床检查发现色素播散综合征的典型表现，包括双侧克-彭二氏梭形色素沉着、虹膜透照缺损和小梁网重度色素沉着。值得注意的是，视力下降眼的晶状体后囊有明显致密的色素沉着。
结论
晶状体后囊色素沉着可能是与色素播散综合征相关的罕见发现。这一发现提示，部分患有该病症的患者可能存在房水流入晶状体后间隙的情况。这种罕见病症的最佳治疗方法尚未确定。
