Understanding Keratoconus
What is Keratoconus?
Keratoconus is a progressive, non-inflammatory eye disorder that alters the structure of the cornea, causing it to thin and adopt a more cone-like shape. This condition can lead to significant vision distortion, including multiple images, streaks, and light sensitivity. Though often perceived as uncommon, keratoconus is actually the most prevalent corneal dystrophy, affecting approximately one in a thousand people globally, irrespective of ethnic background. It typically emerges in adolescence and tends to worsen in the late twenties and thirties.
Overview
Despite extensive research, keratoconus remains somewhat mysterious with unpredictable progression and uncertain causes. It can impede activities like driving if both eyes are affected, but it does not cause blindness. Most patients can manage their symptoms with corrective lenses, maintaining a normal lifestyle. In more advanced cases, surgical intervention may be necessary. Effective management strategies ensure that patients often experience minimal quality-of-life impact.
Symptoms
In the early stages, individuals might notice slight blurring of vision, prompting a visit for corrective eyewear for tasks like reading or driving. Initial symptoms mirror other refractive eye issues. However, as keratoconus progresses, vision can rapidly deteriorate, impairing clarity at all distances, particularly at night. Some may experience a significant disparity in vision between their eyes, increased sensitivity to bright lights, eye strain, or itchiness, but typically without pain.
Key Symptom: Monocular Polyopia
The hallmark symptom of keratoconus is monocular polyopia, where multiple 'ghost' images are perceived instead of a single clear image, especially in high contrast scenarios. Over time, these patterns can evolve, and patients might notice streaks or flares around light sources. Occasionally, images may even appear to move in sync with the heartbeat.
Potential Causes
The exact cause of keratoconus is not yet fully understood. Research suggests it may stem from a variety of factors, including genetic, environmental, or cellular influences, any of which might trigger the onset of the disease.
Treatment Options
In the initial stages, glasses can suffice to correct mild astigmatism. As the condition advances, glasses may no longer provide adequate visual clarity, leading practitioners to recommend contact lenses. These lenses improve vision by using tear fluid to fill gaps between the uneven corneal surface and the smooth lens interior, mimicking a smoother cornea. There are numerous specialized contact lenses for keratoconus, prompting many patients to seek specialists equipped to manage this condition.
