H40.229
Chronic angle-closure glaucoma, unspecified eye
Clinical Classification Guidelines
Medical Intelligence & Overview
Chronic angle-closure glaucoma is a long-term eye condition characterized by increased pressure within the eye, which can lead to damage of the optic nerve and potentially result in vision loss. This form of glaucoma is often less noticeable in its early stages, progressing gradually over time. It involves a blockage or narrowing of the drainage angle in the eye, impairing fluid outflow. Since the exact eye affected is unspecified, this condition can affect either eye and may develop asymptomatically, making regular eye examinations crucial for early detection and management.
Causes & Symptoms
Clinical Causes: Anatomical features such as a thick or forward-shifted iris that closes the drainage angle Age-related changes in eye structures Eye injuries or surgeries that alter eye anatomy Genetic predisposition or family history of glaucoma Certain medical conditions like diabetes or hyperopia
Key Symptoms: Gradual loss of peripheral vision Seeing halos around lights Eye discomfort or headaches in some cases Blurred or reduced vision as the condition progresses Signs often develop slowly, making early detection challenging
Diagnostic & Treatment
Diagnosis Path: Diagnosis involves comprehensive eye examinations, including measuring intraocular pressure (tonometry), visual field testing to evaluate peripheral vision, slit-lamp examination for structural assessment, and gonioscopy to observe the drainage angle. Regular eye check-ups are essential for individuals at risk, especially since symptoms may not be apparent initially.
Treatment Protocols: Managing chronic angle-closure glaucoma aims to lower intraocular pressure and prevent optic nerve damage. Treatment options include medications such as eye drops to reduce eye pressure, laser procedures like laser iridotomy to create an alternative drainage pathway, and surgical interventions in more advanced cases. Consistent follow-up with an eye specialist is vital for monitoring the condition and adjusting therapy as needed.
