H40.239
Intermittent angle-closure glaucoma, unspecified eye
Clinical Classification Guidelines
Medical Intelligence & Overview
Intermittent angle-closure glaucoma is a specific type of eye condition characterized by episodes of increased intraocular pressure caused by a temporary closure of the drainage angle in the eye. This condition affects the eye's ability to drain fluid properly, leading to fluctuating symptoms that can cause significant discomfort and potentially threaten vision if left untreated. The designation 'unspecified eye' indicates that the condition can affect either the right, left, or both eyes but has not been specified in this diagnosis.
Causes & Symptoms
Clinical Causes: Anatomical predisposition, such as a narrow anterior chamber angle Age-related changes in the eye structure Pupil dilation during activities like dim lighting or medication use Certain genetic factors that affect eye drainage Lens thickening or forward displacement Previous eye trauma or surgery
Key Symptoms: Sudden episodes of eye pain Seeing halos or rainbows around lights Blurred or decreased vision during attacks Headaches around the eye or forehead Redness of the eye Nausea or vomiting in severe cases
Diagnostic & Treatment
Diagnosis Path: Tonometry to measure intraocular pressure Gonioscopy to examine the drainage angle of the eye Visual acuity tests to assess clarity of vision Pupil examination under varying lighting conditions Optic nerve assessment to check for damage
Treatment Protocols: Medications such as eye drops to lower intraocular pressure Laser therapy (e.g., laser iridotomy) to create a small hole in the iris, facilitating better fluid flow Surgical procedures if medications and laser treatments are insufficient Regular monitoring of eye pressure and optic nerve health Lifestyle modifications, like avoiding pupil dilation triggers
