A 15 year-old girl presented with complaints of difficult in seeing distant objects with her left eye since childhood. On ocular examination: uncorrected visual acuity was determined by counting fingers 4 m for left eye, and 10/10 for the right eye. And the best-corrected visual acuity for distance in left eye was 1/10. On slit lamp examination of the left eye, we notice a posterior protrusion of the lens capsule associated with posterior subcapsular and cortical cataract in the central area (A,B), and oil droplet reflex was seen in retroillumination (C). While the rest of the exam anterior and posterior segment was normal. Either examination of the right eye was normal. Our diagnosis was non-syndromic unilateral posterior lenticonus. The first clinical description of lenticonus was in 1888 by Meye. This lesion is descriped in literature as a localized bulging of the lens capsule and the underlying cortex of the anterior or, more commonly, the posterior lens capsule, which makes the diagnosis essentially clinical. Several authors have reported that posterior lenticonus may be associated with other abnormalities, such as Lower oculocerebral syndrome, and they reported also that it occurs usually sporadically in approximately 1-4 of every 100,000 children and is mostly unilateral in 8-10% cases.
