H40.249
Residual stage of angle-closure glaucoma, unspecified eye
Clinical Classification Guidelines
Medical Intelligence & Overview
Residual stage angle-closure glaucoma is a condition characterized by persistent eye pressure and optic nerve damage following initial treatment of angle-closure glaucoma. This stage signifies ongoing or remaining effects of the disease after interventions aimed at controlling the intraocular pressure (IOP) have been implemented. It often affects patients who have experienced an acute angle-closure event and continue to have signs of optic nerve damage or incomplete angle opening, despite treatment. Recognizing and managing this stage is crucial to prevent further vision deterioration.
Causes & Symptoms
Clinical Causes: Incomplete or unsuccessful initial treatment of angle-closure glaucoma Progression of optic nerve damage despite lowered intraocular pressure Structural changes in the eye leading to persistent angle closure or closed angles Development of scar tissue that prevents adequate aqueous humor outflow Persistent or recurrent appositional or synechial closure of the angle
Key Symptoms: Reduced peripheral vision Gradual loss of visual acuity Occasional eye pain or discomfort Persistent or fluctuating intraocular pressure readings Sight changes that may progress over time if untreated
Diagnostic & Treatment
Diagnosis Path: Diagnosis involves comprehensive eye examinations, including measurement of intraocular pressure, gonioscopy to evaluate the anterior chamber angle, and assessment of optic nerve health through visual field testing and optic nerve imaging. The ophthalmologist will look for signs of ongoing or residual damage such as nerve fiber layer thinning and visual field defects. Visual acuity testing also helps determine the extent of vision impairment. Imaging studies like ultrasound biomicroscopy can offer additional insights into anterior segment anatomy.
Treatment Protocols: Management of residual stage angle-closure glaucoma typically focuses on controlling intraocular pressure and preventing further optic nerve damage. Treatment options may include:
