7th Character Definition
One of the following 7th characters is to be assigned to each code in subcategory H40.13 to designate the stage of glaucoma
Medical Intelligence & Overview
Pigmentary glaucoma is a specific type of open-angle glaucoma characterized by the buildup of pigment debris within the eye's drainage angle. This condition can lead to increased eye pressure, potentially damaging the optic nerve and causing vision loss if not properly managed. It commonly affects younger adults, especially males, and often develops gradually over time.
Causes & Symptoms
Clinical Causes: Dislodgement of pigment granules from the iris surface into the aqueous humor Accumulation of pigment in the trabecular meshwork, impeding fluid drainage Genetic predisposition contributing to increased pigment dispersion Anatomical eye differences, such as a crack or posterior bowing of the iris Certain eye movements that cause iris rubbing against lens zonules, releasing pigment
Key Symptoms: Gradual loss of peripheral (side) vision Seeing halos or rainbow-colored rings around lights Eye redness or discomfort in some cases Sensitivity to light Presence of dark pigment particles in the front part of the eye Elevated intraocular pressure detected during eye examinations
Diagnostic & Treatment
Diagnosis Path: Diagnosis typically involves a comprehensive eye examination, including:
Treatment Protocols: Treatment aims to reduce intraocular pressure and prevent optic nerve damage. Common approaches include:
