A 78-year-old male farmer by occupation presented with gradually worsening blurry vision in his both eyes (BE). No history of trauma or exposure to infrared radiation. His best-corrected visual acuity was right eye (RE) – 6/36 and left eye (LE) – 6/60. Intraocular pressure by applanation method was RE – 26 mm Hg and LE – 32 mm Hg. Slit lamp examination (SLE) revealed bilateral nuclear cataracts LE > RE and lamellar delamination of the anterior lens capsule in BE [Figure 1]. Fundus examination revealed the cup-to-disc ratio (CDR) – 0.7 in RE and CDR – 0.8 in LE. The patient started on antiglaucoma medications, followed by uneventful cataract extraction in BE. True exfoliation is a rare disorder where the anterior layer of the lens capsule delaminates and appears as thin fluttering membrane in the anterior chamber. Initial capsular splitting occurs along the insertion of disrupted zonules, and peeling progresses centrally with iris movement and aqueous flow. The condition was first reported by Elschnig in 1922 in glassblowers. The largest case series (259) was reported by Teekhasaenee et al. Predisposing factors include infrared radiation, inflammation, trauma, idiopathic, and senile. Wong et al. reported series of senile true exfoliation and 29.2% had preexisting chronic glaucoma. Distinct from psuedoexfoliation (PXF), but both may coexist.
