Bilateral posterior lenticonus

Posterior lenticonus usually occurs unilaterally and sporadically. Only a few cases of uncomplicated bilateral familial posterior lenticonus are previously reported; its aetiology is unknown. We reported a family with two affected siblings. Echography of the posterior segment in one child showed definite posterior hyaloid artery remnants connecting the posterior capsule to the disc. Posterior lenticonus is relatively uncommon anomaly of the lens. Only three cases of uncomplicated bilateral familial posterior lenticonus have been reported. A cone-like defect exists in the posterior capsule that can range in diameter from 2 to 8 mm. Affected subjects commonly present with amblyopia or esotropia during childhood. Bilateral presentation and family incidence are uncommonly seen. We report a family with two affected siblings, one on whom manifested posterior hyaloid artery remnants of the posterior segment on ultrasound

Echography has an invaluable role in the diagnosis of posterior segment pathology when the fundus view is obscured. Occasionally, this information can be misleading to both the echographer and the ophthalmologist. It is imperative that the surgeon be aware of situations where this may arise
