This is a shortened version of the seventeenth chapter of the ICD-9: Diseases of the Digestive System. It covers ICD codes 800 to 999 . The full chapter can be found on pages 473 to 546 of Volume 1, which contains all (sub)categories of the ICD-9.
Corneal abrasion is a scratch to the surface of the cornea of the eye. [3] Symptoms include pain, redness, light sensitivity, and a feeling like a foreign body is in the eye. [1] Most people recover completely within three days. [1] Most cases are due to minor trauma to the eye such as that which can occur with contact lens use or from ...
Conjunctival concretions are generally asymptomatic.Common symptoms include eye discomfort, eye irritation, and foreign body sensation. Sometimes, the larger, harder or multiple concretions make the rubbing off of the superficial layers of the conjunctiva or eyelids to cause conjunctival abrasion, especially prominent when blinking.
The prevalence of congenital corneal opacities (CCO) is estimated to be 3 in 100,000 newborns. This number increases to 6 in 100,000 if congenital glaucoma patients are included. A study of live births in Spain reported that corneal opacities accounted for 3.11% of congenital eye malformations (Bermejo et al, 1998).
Keratitis is a condition in which the eye's cornea, the clear dome on the front surface of the eye, becomes inflamed. [1] The condition is often marked by moderate to intense pain and usually involves any of the following symptoms: pain, impaired eyesight, photophobia (light sensitivity), red eye and a 'gritty' sensation.

Eye injury by impact of small plastic body. Based on the injury to the eyewall (outer fibrous coat of the eye consisting of cornea and sclera) Closed globe injury: the eye globe is intact, but the seven rings of the eye have been classically described as affected by blunt trauma. Types include contusion and lamellar laceration
They affect the right and left eyes equally. They are not caused by outside factors, such as injury or diet. Most progress gradually. Most usually begin in one of the five corneal layers and may later spread to nearby layers. Most do not affect other parts of the body, nor are they related to diseases affecting other parts of the eye or body.
A punctal plug may be inserted into the tear duct by an optometrist or ophthalmologist, decreasing the removal of natural tears from the affected eye. [8] The use of contact lenses may help prevent the abrasion during blinking lifting off the surface layer and uses thin lenses that are gas permeable to minimise reduced oxygenation.
