H40.133
Pigmentary glaucoma, bilateral
Clinical Classification Guidelines
Medical Intelligence & Overview
Pigmentary glaucoma is a type of eye condition characterized by increased intraocular pressure due to pigment debris clogging the eye's drainage system. It mainly affects young to middle-aged adults and can be bilateral, impacting both eyes. Recognizing the symptoms and understanding the causes can help manage the condition effectively.
Causes & Symptoms
Clinical Causes: Disruption of the iris pigment dispersion, leading to pigment granules sloughing into the drainage angle Repeated mechanical rubbing of the iris against the lens, common in cases with a concave iris shape Genetic predisposition affecting the structure or function of eye tissues involved in fluid drainage Anatomical variations of the anterior chamber that facilitate pigment release
Key Symptoms: Hazy or blurred vision Seeing halos around lights Eye redness or discomfort Light sensitivity Gradual loss of peripheral vision Dark pigmentation deposits on the corneal endothelium, iris, or lens
Diagnostic & Treatment
Diagnosis Path: Diagnosis involves a comprehensive eye examination including slit-lamp biomicroscopy, assessment of intraocular pressure, gonioscopy to evaluate the drainage angle, and visual field testing. An ophthalmologist may also examine the pigmentation on the corneal endothelium and iris to confirm pigment dispersion and its effect on the drainage system.
Treatment Protocols: Management focuses on controlling intraocular pressure to prevent optic nerve damage. Treatment options include:
