Lens: lenticonus and lentiglobus

Contributor(s): David L Williams

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
