H11.02
Central pterygium of eye
Clinical Classification Guidelines
Medical Intelligence & Overview
Central pterygium of the eye is a benign growth that develops on the conjunctiva, the clear tissue covering the white part of the eye. This growth extends onto the cornea, the transparent front part of the eye, and can affect vision if it progresses. The term 'central' indicates that the pterygium appears in the central area of the conjunctiva, near the cornea's surface. Although it is generally non-cancerous, it can cause discomfort and visual disturbances if left untreated.
Causes & Symptoms
Clinical Causes: Prolonged exposure to ultraviolet (UV) light from the sun Chronic exposure to environmental irritants such as wind, dust, and smoke Genetic predisposition or family history of pterygium Living in areas with high sunlight exposure, like tropical or desert regions Eye irritation or inflammation that persists over time
Key Symptoms: A visible wedge-shaped growth extending from the conjunctiva onto the cornea, usually on the nasal side Redness and inflammation in the affected eye A sensation of dryness, irritation, or a foreign body feeling Blurring of vision if the growth encroaches onto the central visual axis Cosmetic concerns due to the appearance of the growth
Diagnostic & Treatment
Diagnosis Path: Diagnosis is primarily based on a clinical eye examination by an eye care professional. The doctor will examine the eye using a slit-lamp microscope to assess the size, shape, and location of the pterygium. Additional tests are generally unnecessary but may include other anterior segment examinations or photographs to monitor changes over time. In some cases, if the diagnosis is uncertain or to rule out other ocular conditions, a healthcare professional may perform imaging studies or tissue analysis.
Treatment Protocols: Treatment for central pterygium depends on its size, symptoms, and impact on vision. Approaches include:
