Sunflower cataract in Wilson's disease : transmission electron microscopic study.

Purpose To report ultramicrostructures of anterior capsule of sunflower cataract by the transmission electron microscopic study (TEM) Methods A 37‐year‐old male with liver cirrhosis was referred to department of ophthalmology due to visual disturbance. She has bilateral sunflower cataract & Kayer‐Fleischer ring. Her right eye underwent phacoemulsification with a CCC and intraocular lens implantation. 1. Anterior capsule preparation for transmission electron microscopic examination(TEM) 2. Cross section image by energy filtered TEM 3. Elemental analysis : High‐angle annular dark‐field(HAADF) scanning TEM (STEM) with energy‐dispersive x‐ray analysis (EDAX) Results TEM shows the multiple heterogeneous dense deposits in the anterior lens capsule. HAADF‐STEM shows bright particle deposits. EDAX shows high emission peaks for copper. Conclusion This is first report of TEM study for anterior capsule of sunflower cataract. We found the multiple heterogeneous dense deposits in the anterior lens capsule. And we confirmed that copper was a component of these particles using EDAX. [ABSTRACT FROM AUTHOR]
