H21.233
Degeneration of iris (pigmentary), bilateral
Clinical Classification Guidelines
Medical Intelligence & Overview
Bilateral pigmentary iris degeneration, also known as pigment dispersion syndrome affecting both eyes, is a condition characterized by the abnormal breakdown or deterioration of the iris' pigment layer. The iris is the colored part of the eye that controls the amount of light entering the eye through the pupil. Degeneration of this layer can lead to various vision problems and may be associated with other eye conditions. While it is relatively rare, understanding this condition can aid in recognizing symptoms and seeking appropriate eye care.
Causes & Symptoms
Clinical Causes: Genetic predisposition that affects the integrity of the iris pigment epithelium Structural abnormalities leading to pigment cell breakdown Trauma or injury to the eye Certain eye diseases that involve inflammation or degeneration Age-related changes in ocular tissues
Key Symptoms: Gradual loss of vision or visual disturbances Appearance of pigment granules on the cornea's inner surface or on the iris Light sensitivity or glare issues Presence of dark spots or streaks in the vision Potential development of increased intraocular pressure affecting the optic nerve
Diagnostic & Treatment
Diagnosis Path: Slit-lamp examination to observe pigment dispersion and iris structure Gonioscopy to assess the drainage angle of the eye Intraocular pressure measurement (tonometry) Visual field testing to check for peripheral vision loss Imaging studies, like ocular coherence tomography (OCT), if necessary
Treatment Protocols: Regular monitoring of intraocular pressure to detect glaucoma development Medications such as eye drops to reduce intraocular pressure if glaucoma is present Laser therapy to improve aqueous humor drainage in certain cases Management of associated eye conditions, like inflammation or cataracts Surgical intervention in advanced cases where vision loss or pressure increase becomes severe
