H40.15
Residual stage of open-angle glaucoma
Clinical Classification Guidelines
Medical Intelligence & Overview
Residual stage of open-angle glaucoma, classified under ICD-10 code H40.15, refers to the later phase of this chronic eye condition. This stage indicates that significant optic nerve damage and vision loss have already occurred, but the disease persists with ongoing effects. Open-angle glaucoma is a common form of glaucoma where the drainage angle in the eye remains open, but the eye's fluid cannot drain properly, leading to increased intraocular pressure (IOP). Over time, this pressure can damage the optic nerve, resulting in permanent vision impairment. The residual stage signifies that the disease has progressed beyond early signs, and managing it requires understanding its long-term impacts.
Causes & Symptoms
Clinical Causes: Chronic elevated intraocular pressure due to fluid drainage problems Age-related changes affecting the eye's drainage system Genetic predisposition or family history of glaucoma Certain medical conditions like diabetes or hypertension Previous eye injuries or surgeries contributing to drainage issues Use of corticosteroid medications prolonged exposure
Key Symptoms: Gradual loss of peripheral (side) vision Difficulty seeing in low-light conditions Increased sensitivity to glare Blurring of vision in advanced stages Perception of tunnel vision as the disease progresses Absence of noticeable symptoms in early stages, making regular eye exams essential
Diagnostic & Treatment
Diagnosis Path: Diagnosing the residual stage of open-angle glaucoma involves several eye examinations:
Treatment Protocols: While the residual stage indicates advanced disease, treatments aim to prevent further progression:
