Keratoconus is a progressive affliction, in 90% of cases affecting both eyes. The cornea is the anterior, convex part of the eyeball. It consists of an epithelium and endothelium, which encase two elastic lamina and the stroma of the cornea. As a result of the disease, the cornea becomes thinner and cone shaped. The corneal protuberance leads to deformation of its surface and vision disturbance.
Deteriorating visual acuity is caused by irregular astigmatism, which intensifies as the disease progresses. The keratoconus is most commonly located in the lower part of the cornea, outside of areas influencing vision, hence the early stages might not interfere with eyesight and remain unnoticed by the patient. With time, however, most cases of keratoconus expand and spread over a large enough area of the cornea to significantly impair vision. In the early stage of disease, the patient’s eyesight fluctuates between deterioration and improvement, necessitating frequent changes in lens power for glasses.
Keratoconus most commonly develops over a period of about 10-20 years, after which changes cease. The course of affliction is varied: in some patients, the affliction remains in one stage for many years (or becomes permanent), in others still it develops rapidly or takes the form on periodic deterioration.
In advanced keratoconus stages, the corneal protrusion may lead to localized Descemet membrane bursts, leading to fluids from the anterior eyeball chamber leaking into the corneal layer. This causes pain, sudden blurring of vision, a milky white discoloration of the cornea. Left untreated, keratoconus may force a corneal transplant. Early diagnosis and rapid treatment grant a chance for not only halting keratoconus spread, but also an improvement of vision.
Keratoconus does grow, but usually very slowly. It can also halt at any stage: moderate or serious. As the affliction progresses, the cornea becomes more and more swollen.
The exact causes of keratoconus growth as unknown. There are theories regarding the affliction’s etiology. The root cause is probably a genetic predisposition, as well as a secondary effect of other illnesses.
During routine eye tests, early phases of keratoconus often remain undetected. That is why it is very important to select a competent doctor, with access to specialized equipment allowing them to perform corneal topography.
Keratoconus leads to development of irregular astigmatism which significantly affects quality of vision. The only way to correct the refractive error is wearing hard or hybrid contact lenses since eyeglasses do not improve vision.
