H40.032
Anatomical narrow angle, left eye
Clinical Classification Guidelines
Medical Intelligence & Overview
Anatomical narrow angle, left eye, is a specific eye condition that occurs when the space between the iris and the cornea is narrower than normal, particularly affecting the left eye. This structural configuration can increase the risk of developing angle-closure glaucoma, a serious eye condition that can lead to vision loss if not detected and managed properly.
Causes & Symptoms
Clinical Causes: Genetic predisposition leading to a naturally narrow anterior chamber angle Age-related changes in the eye's anatomy, causing the angle to become narrower over time Certain eye anatomies, such as thicker lenses or larger pupils, which contribute to narrowing of the angle Previous eye surgeries or injuries that alter eye anatomy Conditions that cause the lens to move forward, reducing the space between the iris and cornea
Key Symptoms: Recurrent episodes of eye pain Sudden visual disturbances, such as blurred vision or seeing halos around lights Redness in the affected eye Headache or brow pain Nausea or vomiting in severe cases Gradual loss of peripheral vision in advanced stages
Diagnostic & Treatment
Diagnosis Path: Diagnosis involves a comprehensive eye examination, including measurements of the anterior chamber angle. Eye care professionals use specialized instruments such as gonioscopes to visualize the angle between the iris and cornea. Additional assessments may include intraocular pressure measurement and visual field testing to evaluate any impact on vision.
Treatment Protocols: Management strategies aim to reduce the risk of angle-closure and preserve vision. These can include:
