[Anterior cellular proliferation and silicone implant. Apropos of a case]

We reported a case of pigmentary glaucoma in an elderly black patient, treated surgically with phacoemulsification associated with automatised trabeculectomy. The patient was implanted with a silicone foldable lens introduced in the capsular bag. Three months post-operatively, visual acuity, well restored after surgery, decreased progressively and, biomicroscopic exam revealed a pigmented cellular membrane. Pathogeny of this membrane is discussed.
