Neurotrophic keratitis is unusual eye disorder that affects the cornea. The cornea flexes light permitting it to go through the pupil of the eye, ultimately reaching the retina, where specialized cells called rods and cones convert light to nerve impulses. Neurotrophic keratitis is triggered when the nerves that serve the cornea can not function properly; these nerves bring impulses that aid the cornea function. When the cornea senses stimulation or pressure, the eyelids will close and splits will be produced to shield the cornea and the eye. In advanced neurotrophic keratitis, an indoor layer called the cornea stroma can break down too, causing thinning of the cornea. In advanced stromal melting, the cornea can slim to a severe degree, which can cause a hole or opening up to the within the eye, which can lead to infection and potentially loss of the eye. Due to the fact that the sensitivity of the cornea is lowered, affected individuals frequently do not suffer pain or pain in the eye. The affected cornea can be hurt conveniently and it heals itself slower than unaffected cornea does. Since the epithelial layer is the safety layer of the cornea, an epithelial flaw can leave the eye more vulnerable to infection. Affected individuals might develop scarring of the cornea. As the inner layer called the stroma breaks down and becomes thinner, the cornea can come to be more off-and-on shaped, and more extreme scarring can develop. Neurotrophic keratitis can lead to permanent loss of vision if not correctly dealt with.
