| Introduction|| |
Posterior lens capsular pigmentation is a rare finding. It was first described by Zentmayer in 1938 and is seen in pigment dispersion syndrome (PDS) (where it classically appears as a Schie's or Zentmayer line), blunt ocular trauma, and developmental anomaly.,,
During development, prolonged duration of contact of the pigmented ciliary processes with the posterior lens capsule may lead to pigment deposition over the posterior capsule. It has been suggested that in PDS, pigment deposition on the posterior lens capsule occurs as a result of aqueous humor entry into the Berger's space, secondary to detachment of the anterior hyaloid membrane. Blunt trauma may lead to detachment of the hyaloideocapsular ligament of Wieger and lead to pigment deposition over the posterior lens capsule.,
| Case Report|| |
A 30-year-old male patient presented for a routine ophthalmic examination. He had no history of previous ocular trauma. His uncorrected visual acuity was 6/6 in both eyes and on slit-lamp biomicroscopy, a small area of pigment accumulation was noted in the left eye over the inferior part of the posterior lens capsule in infraduction [Figure 1]a. The posterior segment was within normal limits. Anterior segment-optical coherence tomography showed a hyper-reflective solid structure structure over the posterior lens capsule [Figure 1]b. As the patient was asymptomatic and the pigment clump was away from the visual axis, no intervention was advised.

Thus, in our case, the absence of the signs or symptoms of PDS and a history of blunt ocular trauma point toward the pigment clump being a developmental anomaly.
