How is Keratoconus Diagnosed?
The tests and technologies used to confirm the presence of this eye condition.
Diagnosing Keratoconus involves a thorough eye examination and a review of your medical and family history. An eye doctor (ophthalmologist or optometrist) can diagnose the condition using several tests.
Key Diagnostic Tests
- Slit-Lamp Examination: The doctor uses a special microscope to examine your eye. This helps to see the cornea's shape and look for other potential issues.
- Corneal Topography: This is the most accurate way to diagnose early Keratoconus and track its progression. A computer creates a 3D map of the cornea's surface curve, much like a topographic map of a mountain. This map shows any steepening or irregularities.
- Pachymetry: This test measures the thickness of the cornea. In Keratoconus, the cornea is often thinner than normal.
- Eye Refraction: This standard test, where you look through a device at an eye chart, helps determine your prescription for glasses or contacts. Frequent changes can be an indicator of Keratoconus.
"Advanced imaging like corneal topography allows us to detect Keratoconus earlier than ever before, which is critical for preventing vision loss."
Once diagnosed, your eye doctor will monitor the condition regularly to track its progression and adjust your treatment plan as needed. Early and accurate diagnosis is key to effective management.
