Keratoconus: Types, Causes, Diagnosis and Management

Keratoconus Keratoconus is a progressive eye disorder where the normally round cornea (the clear front part of the eye) thins and bulges into a cone-like shape. This cone shape deflects light as it enters the eye, causing distorted vision. Keratoconus affects roughly one in every 2,000 people, usually starting during puberty and continuing to progress until the mid-30s. Definition Keratoconus is a non-inflammatory, degenerative condition of the cornea characterized by localized thinning, which leads to irregular astigmatism and vision distortion. Types of Keratoconus Forme Fruste Keratoconus : A very mild, non-progressive form often detected during corneal topography. Mild Keratoconus : Slight thinning and distortion of the cornea with minor vision impairment. Moderate Keratoconus : Noticeable vision distortion that often requires corrective lenses. Severe Keratoconus : Significant thinning with marked cone-shaped protrusion, often requiring surgical intervention. Acute Keratoconus (Hydrops) : Sudd…
