Keratoconus is an under-diagnosed bilateral and progressive ectatic condition of the cornea most commonly presenting in teenage years and early adulthood and progressing over time. The condition is characterized by progressive thinning and steepening into a conic formation commonly resulting in irregular astigmatism and reductions in best-corrected visual acuity. The exact cause is not fully understood, but factors like genetics, eye rubbing, allergy/atopy, sleeping with a hand
or pillow pressed against the eye, and certain connective tissue conditions may play a role. If left untreated, progression can lead to vision loss and reduction in quality of life.
