H44.519
Absolute glaucoma, unspecified eye
Clinical Classification Guidelines
Medical Intelligence & Overview
Absolute glaucoma, also known as end-stage glaucoma, is a severe form of glaucoma where the optic nerve has sustained significant damage, resulting in complete loss of vision. The term 'unspecified eye' indicates that the diagnosis applies to either eye when the specific affected eye is not documented. This condition typically develops after prolonged, uncontrolled glaucoma and leads to blindness if left untreated. Understanding the causes, symptoms, and available management options can help in recognizing and addressing this serious eye condition.
Causes & Symptoms
Clinical Causes: Progression of primary open-angle glaucoma or other types of glaucoma Inadequate control of intraocular pressure over time Severe or untreated ocular injuries leading to secondary glaucoma Advanced ocular infections or inflammations causing optic nerve damage Structural abnormalities of the eye that hinder fluid drainage
Key Symptoms: Complete loss of vision in the affected eye Absence of visual perception (no light perception) Possible pain or discomfort in earlier stages before complete vision loss Diminished or absent pupillary light reflex Possible presence of a large, scarred, or shrunken eyeball (phthisis bulbi)
Diagnostic & Treatment
Diagnosis Path: Diagnosis of absolute glaucoma involves a comprehensive eye examination, including assessment of visual acuity, intraocular pressure measurements, and fundoscopy to evaluate optic nerve damage. Imaging studies like ultrasound may be used if the eye's internal structures are shrunken or difficult to examine directly. The key indicator is the complete or near-complete loss of vision, combined with irreversible optic nerve damage observed during examination.
Treatment Protocols: Supportive care for eye comfort and hygiene In some cases, enucleation (removal of the eye) may be necessary if the eye is painful or there's risk of infection Management of any residual ocular or systemic issues Rehabilitation services like vision aids or orientation and mobility training for those with residual vision
