Introduction

• Anterior or posterior protrusion of lens.
• Lenticonus = conical protrusion.
• Lentiglobus = spherical protrusion.
• May be concurrent cataract, eg Miniature Schnauzer - with posterior lenticonus.
• Posterior lentiglobus is most commonly seen in association with multiple ocular anomalies including congenital cataracts.
• Lendectomy for cataract often contraindicated because of concurrent ocular anomalies/complications, eg persistent hyaloid vasculature, microphthalmos.

Pathogenesis

Pathophysiology

• Congenital lens developmental anomaly, often associated with multiple ocular defects.

Timecourse

• Congenital ~ is present at birth but visual defects may not be obvious until later.
