Understanding Keratoconus: A Comprehensive Guide to Causes, Symptoms, and Treatment Options
This article is a guideline only and should not be construed as medical advice. Always contact your eye care doctor with questions and for treatment options. Keratoconus is a progressive eye condition that affects the cornea, which is the clear, dome-shaped front surface of the eye. In individuals with keratoconus, the cornea gradually thins and bulges into a cone-like shape instead of maintaining its normal round curvature. This abnormality can lead to distorted vision and visual impairment. Causes of Keratoconus The exact cause of keratoconus is not well understood, but it is believed to involve a combination of genetic, environmental, and hormonal factors. The condition typically starts during adolescence or early adulthood and progresses over time. Several factors may contribute to the development of keratoconus. These include: Genetics: A family history of keratoconus increases the risk. Eye Rubbing: Constant rubbing of the eyes may contribute to corneal thinning. Connective Tissue Disorders: Conditions such as Ehlers-Danlos syndrome may be linked to keratoconus. Environmental Factors: UV light exposure and oxidative stress may play a role. How Keratoconus Affects Daily Life How keratoconus affects daily life can vary from person to person, but some common effects include: Visual Distortions: Keratoconus often causes blurred and distorted vision. Straight lines may appear wavy, and individuals may experience multiple images, ghosting, or halos around lights. Frequent Changes in Prescription: Due to the progressive nature of keratoconus, individuals may experience frequent changes in their eyeglasses or contact lens prescriptions. Adjustments may be needed to maintain optimal vision. [...]
