What Is Keratoconus? Early Signs, Diagnosis, and Treatment
Keratoconus is a progressive eye condition in which the cornea becomes thinner and bulges forward, causing distorted and blurry vision. Although it typically appears during adolescence, the first signs often begin in childhood as rapidly increasing myopia and astigmatism.
Early diagnosis is essential because keratoconus can be stabilized if detected at an early stage. If missed, the disease may progress and lead to severe vision loss.
Early Signs in Children: Rapidly Increasing Myopia and Astigmatism
In many children, the earliest symptom of keratoconus is frequent changes in eyeglass prescription.
At routine check-ups, this is often interpreted as a normal increase in refractive error, and new glasses are prescribed.
However, this pattern may indicate early keratoconus, which cannot be detected by a standard refraction exam alone.
For accurate diagnosis, corneal topography is required.
Why Is Early Diagnosis Often Missed?
Keratoconus in its early phase causes very subtle symptoms. Without topographic imaging, the disease may remain unnoticed until it significantly progresses.
Common reasons for delayed diagnosis:
- Busy clinic settings with limited time for advanced imaging
- Assuming that rapid prescription changes are normal
- Lack of routine topography screening in children
- Limited access to specialized diagnostic devices
Keratoconus cannot be detected reliably without corneal topography.
How Is Keratoconus Diagnosed?
Modern imaging technologies such as Pentacam, Sirius, and other topography systems allow detailed assessment of:
- Corneal curvature
- Thickness distribution
- Irregularity patterns
- Early signs of ectasia
These measurements are crucial for detecting keratoconus before the disease progresses.
Early Diagnosis Protocol at Kaşkaloğlu Eye Hospital
At Kaşkaloğlu Eye Hospital, corneal topography is performed on every patient during the very first examination—regardless of age.
This protocol ensures:
- Early detection of keratoconus
- Prevention of unnecessary prescription changes
- Timely evaluation of progression risk
- Early planning of cross-linking (CXL) when needed
This systematic approach has enabled many patients to receive early diagnosis and avoid advanced disease.
Awareness Efforts by Prof. Dr. Mahmut Kaşkaloğlu
Prof. Mahmut Kaşkaloğlu consistently emphasizes the importance of early topography screening on national and international platforms.
His goal is to increase awareness among doctors and families so that:
- Children with rapidly increasing myopia and astigmatism are evaluated properly
- Parents understand the importance of topography
- Keratoconus can be diagnosed before significant vision loss occurs
Symptoms of Keratoconus
- Blurred or distorted vision
- Light sensitivity and glare
- Ghosting or double vision
- Frequent changes in eyeglass prescription
- Difficulty with contact lens tolerance
These symptoms require immediate corneal topography.
Treatment Options for Keratoconus
- Corneal Cross-Linking (CXL)
The only proven method to stop disease progression in early and moderate stages.
- Special Contact Lenses
RGP, hybrid, or scleral lenses improve vision by smoothing the irregular optical surface.
- Intrastromal Ring Segments ( Keraring, CAIRS)
Improve corneal shape and visual quality in selected cases.
- Topography-Guided Laser + CXL
Applied in selected early cases to reduce irregularities.
- Corneal Transplantation
Reserved for advanced keratoconus when other treatments are insufficient.
Conclusion: Early Detection Protects Vision
Keratoconus is manageable when diagnosed early.
Routine corneal topography at Kaşkaloğlu Eye Hospital provides a significant advantage in early detection and protects patients from preventable vision loss.
