[Atypical location of lenticular coloboma]

We report the case of a 37-year old patient with no particular past medical history presenting to the Ophthalmology Department for lens correction. Examination of the right eye showed corrected visual acuity of 6/10e, refractive error of -1.50 (-6,25 to 56°); the examination of the anterior segment objectified lenticular coloboma in the superior temporal area with zonular deficiency ranging from 8h to 11h and opacity of the crystalline. The examination of the iris and fundus examination were normal. Left eye exam was normal. Colobomas are congenital malformations of the eye secondary to an abnormal closure of the foetal fissure. Lenticular coloboma is rare, secondary to uveal coloboma resulting in indentation of the lens periphery. It usually occurs in the inferonasal region. The peculiarities of our case study is the occurrence of lenticular coloboma in the superior temporal area. It is essential to search for opacity of the crystalline in patients with other colobomatous abnormalities and associated ocular malformations such as cataract, microphthalmia or ectopia of the crystalline.
