True exfoliation or capsular delamination is a very rare disease characterized by splitting of the superficial layers from the deeper layers of the lens capsule.[1],[2],[3] Though the exact etiology is unclear, it is presumed to be caused by infrared radiation exposure as seen in glassblowers. Yet, a recent study has reported this entity in the general population, which may therefore be related to exposure to extreme heat in changed environmental conditions. We report the histopathological case of such a case in a housewife and discuss differentials with possible etiology in such cases.

A 54-year-old female presented with diminution of vision in both eyes for 5 months. Slit-lamp examination showed a smooth glistening membrane arising from the anterior lens capsule in the left eye, with undulating movements and phacodonesis [Figure 1]. The patient was a housewife using traditional cooking methods with wood/gas fire. Histopathological examination of the lens capsule during cataract surgery revealed lamellar split of the capsular layers [blue arrows, [Figure 1]b and vesicular degeneration in the underlying epithelial layer. True exfoliation membrane should be differentiated from capsular dehiscence[1],[2],[3] and may be found in housewives using gas fire.
