H40.242
Residual stage of angle-closure glaucoma, left eye
Clinical Classification Guidelines
Medical Intelligence & Overview
Residual stage of angle-closure glaucoma in the left eye refers to the ongoing effects and limitations caused by this specific eye condition after the initial phase has been managed or stabilized. This form of glaucoma involves increased pressure within the eye due to a narrowing or closure of the drainage angle, which impairs the outflow of aqueous humor. When the condition enters a residual stage, it indicates that some damage or persistent symptoms continue despite treatment efforts. Recognizing and understanding this stage is important for ongoing eye health management and preventing further vision loss.
Causes & Symptoms
Clinical Causes: Progression from primary angle-closure glaucoma if not effectively managed Incomplete or delayed treatment of acute angle-closure glaucoma episodes Anatomical features such as a narrow anterior chamber angle that predispose to angle closure Age-related changes in the eye's structures Other eye conditions that worsen aqueous humor drainage
Key Symptoms: Persistent or recurring elevated intraocular pressure Blurred vision or visual disturbances Seeing halos around lights Eye discomfort or mild pain Sensitivity to light Potential for ongoing damage to optic nerve No significant symptoms in some cases, but risk of progressive vision loss
Diagnostic & Treatment
Diagnosis Path: Diagnosis is typically made through a comprehensive eye examination which may include:
Treatment Protocols: Management of the residual stage of angle-closure glaucoma in the left eye may involve:
