Abstract
The Christmas tree cataract is a rare type of lens opacification characterized by deposits of needle-shaped polychromatic cortex deep in the core, that can be isolated or associated with other opacities. We report and record, through photographs, two cases of this type of lens opacity.
Highlights
Christmas tree cataract, called starry cataract, is a rare type of opacity in the crystalline characterized by polychromatic needle-shaped deposits in the deep cortex and nucleus thereof which may be isolated or associated to other opacities[1]
Two cases of cataract in Christmas tree seen at the Eye Institute of Goiânia were selected
There are case reports of the association vetween cataract in Christmas tree and myotonic dystrophy, called Steinert’s disease, which is characterized by a delay in muscle relaxation after a volunteer effort
Summary
Called starry cataract, is a rare type of opacity in the crystalline characterized by polychromatic needle-shaped deposits in the deep cortex and nucleus thereof which may be isolated or associated to other opacities[1]. It is presented unilaterally or asymmetrically bilaterally[2]. Pau and Förster[4] suggest that the composition of the opacities would mostly be cholesterol. Shun-Shin et al[5] suggested cystine as the substance related to the formation of the Christmas tree opacities typical of cataract.
