Pigment dispersion syndrome usually manifests bilaterally, and asymmetric involvement is unusual. When asymmetry is present, the eye with greater involvement may have an additional exacerbating condition or the eye with less involvement may be protected. Analysis of such cases should further elucidate the mechanism of the disorder and its development and regression. We examined four patients in whom unilateral cataract formation or extraction was associated with reduced clinical signs of pigment dispersion syndrome in the affected eye. Cataract formation, by inducing relative pupillary block, appears to decrease or prevent the manifestation of pigment liberation.
色素播散综合征通常双侧发病，不对称受累情况并不常见。当出现不对称时，受累较重的眼睛可能存在额外的加重因素，或者受累较轻的眼睛可能受到了保护。对此类病例的分析应能进一步阐明该疾病的机制及其发生发展和消退过程。我们检查了4例患者，这些患者患眼单侧白内障形成或摘除后，色素播散综合征的临床体征减轻。白内障的形成通过诱发相对性瞳孔阻滞，似乎减少或阻止了色素释放的表现。
