Benefits of Corneal Epithelial Mapping

The cornea, or outer surface of the eye, has five layers and the health of this delicate tissue is crucial in maintaining good vision and ocular comfort.  Light first hits our tear film and cornea, then travels through the pupil, lens, and vitreous gel.  It then lands on our retina and the optic nerve which sends signals to our brain and an image is formed.  Therefore, if the cornea is unhealthy, the image will be blurred and light sensitivity may worsen.  

There are many conditions that can impact corneal health.  Dry eye can cause the corneal cells to suffer, leading to a breakdown of the epithelium (surface layer) and subsequent blur, irritation and light sensitivity.  Astigmatism is when the cornea is oval shaped rather then round.  When light hits an astigmatic cornea, it bends and scatters creating blur and ghosting around lights.  

Several genetic conditions can cause corneal warpage including epithelial basement membrane dystrophy, Fuch’s dystrophy, pellucid marginal degeneration and keratoconus.  

At Sorella Optique and Eyecare, Dr. Tinari incorporates enhanced corneal epithelial mapping technology in order to diagnose several corneal diseases sooner than traditional corneal topography.  The earlier a diagnoses is made, the sooner treatment can commence to prevent irreversible vision loss. 

Epithelial mapping is essential before and after refractive surgeries to ensure the health of the cornea.  Dr. Tinari recommends a baseline corneal scan for all patients as part of a routine eye exam.
