Lenticonus
Lenticonus is an abnormality of the lens of the eye in which it has a steeper curvature than is normal and bulges forward in the shape of a blunted cone.
Lenticonus may also be described as "a conical projection of the anterior or posterior surface of the lens [of the eye]".
Because lenticonus may affect either the front surface (anterior) of the lens or, occasionally, the back surface (posterior) of the lens, it may be classified as:
- Anterior lenticonus
- Posterior lenticonus
Of these two possibilities, anterior lenticonus is more common and may be associated with Alport's syndrome.
Clarification:
Note the importance of the shape of the distortion of the lens:
If the bulging of the lens is spherical rather than conical the condition is called lentiglobus. See also, for comparison keratoconus and keratoglobus.
Lenticonus is a rare condition that is usually congenital, which means "present since birth".
