[Unusual regressive cataract with petaloid-shaped crystalline core].

We report the case of a 38-year old patient with no previous medical-surgical history, victim of traumatic contusion injury in the right eye resulting from stone blow which occurred 20 years before and experiencing progressive decrease in visual acuity over the last 10 years. Ophthalmologic examination of the right eye showed visual acuity of counting fingers and ocular tone 11 mmHg. Examination of the anterior segment after dilation of the pupil showed regressive cataract with petaloid-shaped crystalline core. The petals had dense edges and sutures. Given the inaccessibility of the ocular fundus and that the examination of the left eye objectified no abnormalities, ocular ultrasound was performed.
