H40.24

Residual stage of angle-closure glaucoma

Clinical Classification Guidelines

Medical Intelligence & Overview

The residual stage of angle-closure glaucoma is a phase that occurs after an initial episode of angle-closure, where some damage to the eye's optic nerve remains. This condition is characterized by ongoing changes that may affect vision, even if the immediate pressure has been controlled. Recognizing and understanding this stage is crucial for ongoing eye health management and to prevent further vision loss.

Causes & Symptoms

Clinical Causes: Previous episodes of angle-closure glaucoma causing irreversible damage to the optic nerve Incomplete treatment of initial glaucoma attack Progressive narrowing of the anterior chamber angle due to structural changes Persistent or recurrent rise in intraocular pressure after initial intervention

Key Symptoms: Gradual loss of peripheral vision Blurred vision or glare, especially in low light conditions Seeing halos around lights Eye discomfort or mild pain Persistent or fluctuating intraocular pressure No symptoms may be present in early residual phase; some individuals may notice decreased visual acuity over time

Diagnostic & Treatment

Diagnosis Path: Diagnosis involves comprehensive eye examinations including slit-lamp assessment, intraocular pressure measurements, and visual field testing. Gonioscopy is performed to evaluate the anterior chamber angle, and optic nerve imaging may be used to assess nerve damage. These evaluations help determine the extent of residual damage and monitor disease progression.

Treatment Protocols: Management strategies focus on preserving remaining vision and preventing further glaucomatous damage. These may include: - **Medical therapy:** Use of eye drops or systemic medications to lower intraocular pressure. - **Laser procedures:** Such as laser trabeculoplasty to improve fluid drainage. - **Surgical interventions:** In more advanced cases, procedures like trabeculectomy or drainage devices may be considered. - **Regular monitoring:** Ongoing eye exams to assess intraocular pressure and optic nerve health. Treatment plans are tailored to the individual based on the severity of residual damage and overall eye health.

Reimbursement claims with a date of service on or after October 1, 2015 require the use of ICD-10-CM codes.
