The cornea is the clear window on the front of the eye. It is usually a regular spherical dome in shape. The substance of the cornea consists of hundreds of layers that are linked to each other by a substance called collagen. If these collagen cross-links between layers are lost due to #keratoconus In RaJKOT, there is a progressive corneal thinning and stretching which gradually progresses, often in both #eyes. Normal pressure within the eye causes the cornea to bulge forward into an irregular cone shape. When light enters the eye, it first passes through the cornea. If the cornea has turned conical, there is distortion of the image. The eye develops astigmatism & myopia and the vision may become severely blurred. Symptoms :::: # Early stages just having the need for spectacle correction. # Visual acuity becomes impaired at all distances, and night vision is sometimes quite poor. # As the disease progresses, the vision deteriorates. # Some individuals have vision in one eye that is markedly worse than that in the other eye.
