H44.51
Absolute glaucoma
Clinical Classification Guidelines
Medical Intelligence & Overview
Absolute glaucoma, also known as end-stage glaucoma, is a severe form of eye disease that results in complete vision loss in the affected eye. This condition represents the final phase of untreated or severe glaucoma, where the optic nerve has sustained significant damage, and the eye can no longer process visual information. Recognizing the symptoms and understanding the causes of absolute glaucoma can help in timely medical intervention, although damage at this stage is typically irreversible.
Causes & Symptoms
Clinical Causes: Uncontrolled primary open-angle glaucoma over many years Chronic angle-closure glaucoma that is left untreated Trauma or injury to the eye leading to optic nerve damage Chronic inflammation or infections affecting the eye Advanced secondary glaucomas due to other eye conditions or systemic diseases
Key Symptoms: Complete loss of vision in the affected eye Disappearance of peripheral vision leading to tunnel vision Pain or discomfort is usually absent at this stage In some cases, a swollen or enlarged eye may be observed No perception of light or visual stimuli
Diagnostic & Treatment
Diagnosis Path: Diagnosing absolute glaucoma involves comprehensive eye examination, including visual acuity tests, intraocular pressure measurement, and detailed assessment of the optic nerve and retina. Imaging tests like optical coherence tomography (OCT) or gonioscopy may be used to evaluate the eye structures. Since the damage is irreversible, the primary goal is to assess the extent of optic nerve damage and rule out other causes of vision loss.
Treatment Protocols: Since absolute glaucoma signifies complete vision loss, treatment mainly focuses on managing discomfort and preventing potential complications in the unaffected eye. Options include: - Medications to lower intraocular pressure if there is still some residual vision or risk in the other eye. - Surgical procedures to relieve eye pressure, although these are less effective once the eye has become absolute. - Supportive measures such as visual aids or low vision services for adaptation. It is important to note that once the eye reaches this stage, restoring vision is not feasible, emphasizing the importance of early detection and treatment of glaucoma before progression to this advanced state.
