Which of the following syndrome is associated with Lenticonus?

Bilateral anterior lenticonus is associated with Alpo's syndrome. The lens capsule in Alpo's syndrome is thin and has linear dehiscences. Alpo's syndrome is also associated with deafness and hereditary hemorrhagic nephritis. In lenticonus the surface of the lens has a conical configuration. It could either be anterior or posterior and is caused by the focal thinning of the lens capsule. Anterior lenticonus is associated with Alpo's syndrome. Posterior lenticonus is usually a unilateral sporadic condition that is not associated with other ocular or systemic disease. Ref: Eye Pathology: An Atlas and Text By Ralph C. Eagle 2nd edn page 107.
