H40.233
Intermittent angle-closure glaucoma, bilateral
Clinical Classification Guidelines
Medical Intelligence & Overview
Intermittent angle-closure glaucoma is a type of glaucoma characterized by episodes of increased intraocular pressure due to closure of the drainage angle in the eye. When this condition affects both eyes, it is referred to as bilateral. This condition can cause temporary vision changes and, if left untreated, may lead to permanent optic nerve damage and vision loss. Recognizing symptoms and seeking prompt ophthalmologic evaluation are essential for effective management.
Causes & Symptoms
Clinical Causes: Anatomical predisposition where the iris is positioned close to the drainage angle of the eye Shallow anterior chamber in the eye, often seen in hyperopic (farsighted) individuals Pupil dilation during low light or under stress, leading to angle closure Acute or intermittent episodes of angle closure triggered by sudden pupil dilation Age-related changes in eye structures that can affect the angle anatomy
Key Symptoms: Sudden episodes of eye pain or discomfort Visual disturbances such as blurred vision or seeing halos around lights Redness in the affected eye Nausea and vomiting during severe attacks Temporary loss of vision during episodes Intermittent nature of symptoms, with periods of normal vision between episodes
Diagnostic & Treatment
Diagnosis Path: Diagnosis involves comprehensive eye examinations performed by an ophthalmologist, including:
Treatment Protocols: Management of intermittent angle-closure glaucoma aims to reduce intraocular pressure and prevent attacks. Treatment options include:
