KERATOCONUS: CAUSES AND TREATMENTS
How Is Keratoconus Diagnosed?
Diagnosing Keratoconus is somewhat tricky because its symptoms mimic those of astigmatism.
When you arrive for an eye exam, your optometrist will perform a series of physical examinations for the health and function of your eyes as well as complete a detailed family history to include any ophthalmic disorders. Some of the basic testing may include:
- Snellen chart - The standard visual acuity chart with progressively smaller letters or shapes
- Keratometer - Instrument designed to measure the curvature of the cornea
- Retinoscopy - Procedure in which the optometrist uses a focused light beam to test the reflection of the retina
- Slit lamp examination - Procedure in which the doctor shines a light into the eye for better visual examination of the eye
Corneal topography, a device creates a topographical map of the cornea's shape that can be valuable in determining the degree, or stage, of the keratoconus and monitor any progression, may also be used.
How Is Keratoconus Treated?
Traditionally, patients’ visual distortions have been treated with the use of hard contact lenses, which also inhibit further changes to the cornea. Advances in contact lens materials have also lead to the development of hybrid lenses created specifically for those with keratoconus. All of these lenses must be fitted by a specialist with knowledge of the challenges associated with the conical shape distinctive of the condition.
There are a number of surgical options also available. Surgical solutions are usually reserved for severe cases of keratoconus in which multiple complications have made the preferred contact lens treatments ineffective.
