Clinical Classification

Clinical Information

  • Exfoliation Syndrome

    the deposition of flaky, translucent fibrillar material most conspicuous on the anterior lens capsule and pupillary margin but also in both surfaces of the iris, the zonules, trabecular meshwork, ciliary body, corneal endothelium, and orbital blood vessels. it sometimes forms a membrane on the anterior iris surface. exfoliation refers to the shedding of pigment by the iris. (newell, ophthalmology, 7th ed, p380)
  • Glaucoma

    an ocular disease, occurring in many forms, having as its primary characteristics an unstable or a sustained increase in the intraocular pressure which the eye cannot withstand without damage to its structure or impairment of its function. the consequences of the increased pressure may be manifested in a variety of symptoms, depending upon type and severity, such as excavation of the optic disk, hardness of the eyeball, corneal anesthesia, reduced visual acuity, seeing of colored halos around lights, disturbed dark adaptation, visual field defects, and headaches. (dictionary of visual science, 4th ed)
  • Glaucoma Drainage Implants

    devices, usually incorporating unidirectional valves, which are surgically inserted in the sclera to maintain normal intraocular pressure.
  • Glaucoma, Angle-Closure

    a form of glaucoma in which the intraocular pressure increases because the angle of the anterior chamber is blocked and the aqueous humor cannot drain from the anterior chamber.
  • Glaucoma, Neovascular

    a form of secondary glaucoma which develops as a consequence of another ocular disease and is attributed to the forming of new vessels in the angle of the anterior chamber.
  • Glaucoma, Open-Angle

    glaucoma in which the angle of the anterior chamber is open and the trabecular meshwork does not encroach on the base of the iris.
  • Low Tension Glaucoma

    a form of glaucoma in which chronic optic nerve damage and loss of vision normally attributable to buildup of intraocular pressure occurs despite prevailing conditions of normal intraocular pressure.
  • Ocular Hypertension

    a condition in which the intraocular pressure is elevated above normal and which may lead to glaucoma.
  • Weill-Marchesani Syndrome

    rare congenital disorder of connective tissue characterized by brachydactyly, joint stiffness, childhood onset of ocular abnormalities (e.g., microspherophakia, ectopia lentis; glaucoma), and proportionate short stature. cardiovascular anomalies are occasionally seen.
  • Congenital Glaucoma

    glaucoma, the cause of which is present at birth.
  • Primary Congenital Glaucoma

    congenital glaucoma that arises independent of another pathologic process, disease, or injury.
  • Primary Congenital Glaucoma 3A|GLC3A

    an autosomal recessive form of congenital glaucoma caused by mutation(s) in the cyp1b1 gene, encoding cytochrome p450 1b1.
  • Bilateral Glaucoma

    increased pressure in both eyeballs due to obstruction of the outflow of aqueous humor.
  • Microcornea

    a congenital abnormality characterized by an abnormally small cornea. the horizontal corneal diameter is less than 10mm or less than 9mm in newborns. it is associated with an increased risk of glaucoma.

Present on Admission (POA)

Q15.0 is exempt from POA reporting - The Present on Admission (POA) indicator is used for diagnosis codes included in claims involving inpatient admissions to general acute care hospitals. POA indicators must be reported to CMS on each claim to facilitate the grouping of diagnoses codes into the proper Diagnostic Related Groups (DRG). CMS publishes a listing of specific diagnosis codes that are exempt from the POA reporting requirement. Review other POA exempt codes here.

Patient Education


Glaucoma

Glaucoma is a group of diseases that can damage the eye's optic nerve. It is a leading cause of blindness in the United States. It usually happens when the fluid pressure inside the eyes slowly rises, damaging the optic nerve. Often there are no symptoms at first. Without treatment, people with glaucoma will slowly lose their peripheral, or side vision. They seem to be looking through a tunnel. Over time, straight-ahead vision may decrease until no vision remains.

A comprehensive eye exam can tell if you have glaucoma. People at risk should get eye exams at least every two years. They include:

  • African Americans over age 40
  • People over age 60, especially Mexican Americans
  • People with a family history of glaucoma

There is no cure, but glaucoma can usually be controlled. Early treatment can help protect your eyes against vision loss. Treatments usually include prescription eyedrops and/or surgery.

Early-onset glaucoma

Glaucoma is a group of eye disorders in which the optic nerves connecting the eyes and the brain are progressively damaged. This damage can lead to reduction in side (peripheral) vision and eventual blindness. Other signs and symptoms may include bulging eyes, excessive tearing, and abnormal sensitivity to light (photophobia). The term "early-onset glaucoma" may be used when the disorder appears before the age of 40.

In most people with glaucoma, the damage to the optic nerves is caused by increased pressure within the eyes (intraocular pressure). Intraocular pressure depends on a balance between fluid entering and leaving the eyes.

Usually glaucoma develops in older adults, in whom the risk of developing the disorder may be affected by a variety of medical conditions including high blood pressure (hypertension) and diabetes mellitus, as well as family history. The risk of early-onset glaucoma depends mainly on heredity.

Structural abnormalities that impede fluid drainage in the eye increase ocular pressure. These abnormalities may be present at birth and usually become apparent during the first year of life. Such structural abnormalities may be part of a genetic disorder that affects many body systems, called a syndrome. If glaucoma appears before the age of 3 without other associated abnormalities, it is called primary congenital glaucoma.

Other individuals experience early onset of primary open-angle glaucoma, the most common adult form of glaucoma. If primary open-angle glaucoma develops during childhood or early adulthood, it is called juvenile open-angle glaucoma.
