“…In our study, the lens epithelium cells showed vacuole-like spaces in the cytoplasm and expansion of the intercellular spaces, similar to those in patients with true exfoliation [2,4]. These similarities in the horizontal, tangential splits of the anterior capsule and changes to the lens epithelium cells support a relation between the double-ring sign and true exfoliation.…”

“…Additional electron microscopic studies of cases of true exfoliation of the anterior lens capsule have demonstrated similar findings. [4][5][6] In some instances, the underlying epithelial cells have been reported as abnormal. This anterior capsular delamination and true exfoliation has also been demonstrated by ultrasound biomicroscopy.…”

SummaryA rare case of delamination and replication of the anterior lens capsule into prominent floating folds in the anterior chamber approximately 55 years after a penetrating injury to the eye and anterior lens capsule is reported. Classically, true exfoliation of the anterior lens capsule has been reported in individuals who have been exposed to intense heat over a prolonged period. However, more recently cases of true exfoliation of the anterior lens capsule have been reported in patients who have not been occupationally exposed to high temperatures and associated infrared radiation. A brief review of the literature concerning true exfoliation of the lens capsule in the absence of intense heat exposure is included. Associations with trauma, inflammation, advanced age, hyperopia, glaucoma, and capsular protein abnormality have been reported, but the pathogenesis of this rare clinical finding remains conjectural. Case ReportAn 88-year-old, white man presented with a complaint of gradually decreasing vision over many months. He related a history of sustaining an injury to his left eye in 1944 while serving in the Army in France during World War II. On questioning, the patient denied an occupational exposure to the intense heat. (Figure 1). Careful slit-lamp examination of the anterior chamber in this eye revealed a diaphanous membrane in a multiple fold pattern that undulated slowly on eye movement and exhibited a petaloid appearance.It was apparent that this membranous structure emanated from within the pupil and was not adherent to the iris or cornea at any point. Dilated examination revealed a moderately dense, brunescent, nuclear cataract in the right eye and a very dense, brunescent, nuclear cataract in the left eye. There was also noted to be a small anterior subcapsular cataract centrally in the left eye. When the pupil was dilated, the membrane assumed a relatively unfolded pattern (Figures 2 and 3).On examination, the folds could be seen to originate from the area of the anterior subcapsular lens opacity.

“…1 An association with glassblowing has been established, 1,2 but the condition has rarely been reported in bakers. 1 Other reports document the condition in steelworkers and blacksmiths. All these occupations involve prolonged exposure to infrared radiation from extremely hot materials (eg, glass, steel) or open ovens or furnaces.…”

We report a case of true exfoliation of the crystalline lens in a 53-year-old baker who presented with reduced vision due to cataract. Phacoemulsification cataract surgery with intraocular lens implantation was performed, and the anterior capsule was analyzed histologically. Preoperative clinical and anterior segment optical coherence tomography observations are presented, with a description of the modified phacoemulsification technique and histopathology. A possible mechanism of pathogenesis is proposed in the context of the histopathology.
