摘要

摘要:色素分散综合征(PDS)的典型表现通常包括虹膜中外周穿越性缺损、Krukenberg纺锤体和致密均匀的小梁色素沉着。其他微妙的,有时被忽视的特征包括晶状体小带上的色素,晶状体前囊上的色素和晶状体后囊赤道上的色素。病例:这种独特的PDS表现为双侧、密集、倾斜和对称的色素沉积沿晶状体后囊,其形状、密度和范围在3年内发生了变化。讨论:文献中很少有报道描述与PDS相关的晶状体后囊中央性色素积累。有报道的情况下,色素沉积沿中央方面的晶状体后囊,一些改变随着时间的推移,虽然没有双边和对称。有迹象表明,这种中央色素沉积可能与韦格韧带断裂有关,韦格韧带使后房室和晶状体后囊之间能够通信。这种情况下,后晶状体囊上的曲线、对称和变化的色素沉积可能提示PDS的另一个关键特征。

Curvilinear, symmetrical, and profound pigment deposition on the posterior lens capsule in a patient with bilateral pigmentary dispersion syndrome.

Introduction: The classic presentation of pigmentary dispersion syndrome (PDS) often consists of midperipheral iris transillumination defects, Krukenberg's spindle, and dense homogeneous trabecular pigmentation. Other subtle, sometimes overlooked features include pigment on the lens zonules, pigment on the anterior lens capsule and pigment along the equator of the posterior lens capsule.

Case: This unique presentation of PDS presented with bilateral, dense, oblique, and symmetrical pigment deposition along the posterior lens capsule that changed in shape, density, and extent over the span of 3 years.

Discussion: There have been few reports in the literature that describe a central accumulation of pigment along the posterior lens capsule associated with PDS. There are reported cases of pigment deposition along the central aspect of the posterior lens capsule, some changing over time, although none were bilateral and symmetrical. There are suggestions that perhaps this central pigment deposition is related to a break in the ligament of Weiger, allowing communication between the posterior chamber and posterior lens capsule. This is a case in which curvilinear, symmetrical, and changing pigment deposition on the posterior lens capsule is suggestive of perhaps another key features of PDS.

期刊介绍: Eye and Brain is an international, peer-reviewed, open access journal focusing on basic research, clinical findings, and expert reviews in the field of visual science and neuro-ophthalmology. The journal’s unique focus is the link between two well-known visual centres, the eye and the brain, with an emphasis on the importance of such connections. All aspects of clinical and especially basic research on the visual system are addressed within the journal as well as significant future directions in vision research and therapeutic measures. This unique journal focuses on neurological aspects of vision – both physiological and pathological. The scope of the journal spans from the cornea to the associational visual cortex and all the visual centers in between. Topics range from basic biological mechanisms to therapeutic treatment, from simple organisms to humans, and utilizing techniques from molecular biology to behavior. The journal especially welcomes primary research articles or review papers that make the connection between the eye and the brain. Specific areas covered in the journal include: Physiology and pathophysiology of visual centers, Eye movement disorders and strabismus, Cellular, biochemical, and molecular features of the visual system, Structural and functional organization of the eye and of the visual cortex, Metabolic demands of the visual system, Diseases and disorders with neuro-ophthalmic manifestations, Clinical and experimental neuro-ophthalmology and visual system pathologies, Epidemiological studies.
