Keratoconus:
A recent study has revealed that the treatment of keratoconus, a condition that threatens vision, can worsen even after treatment.
- It is a vision disorder that occurs when the normally round cornea (the front part of the eye) becomes thin and irregular (cone) shaped.
- This abnormal shape prevents the light entering the eye from being focused correctly on the retina and causes distortion of vision.
- Keratoconus often starts when people are in their late teens to early 20s.
- The vision symptoms slowly get worse over a period of about 10 to 20 years.
- It often affects both eyes and can lead to very different vision between the two eyes.
- Symptoms can differ in each eye, and they can change over time.
- Treatment and Prevention:
- There is no known prevention for keratoconus.
- Early stages can be treated with glasses, but with progression of the disease into late childhood and early adulthood, corneal transplantation may be needed to restore sight.
- Corneal collagen cross-linking is a procedure designed to stop the progression of keratoconus or slow it down.
