H44.511
Absolute glaucoma, right eye
Clinical Classification Guidelines
Medical Intelligence & Overview
Absolute glaucoma, also known as end-stage glaucoma, is a severe form of glaucoma where vision loss has become complete or nearly complete. When it affects the right eye, it shows similar characteristics to its occurrence in the left eye but requires specific attention due to its impact on one eye's vision. This condition results from prolonged increased pressure within the eye, leading to significant damage to the optic nerve. Recognizing and understanding absolute glaucoma is vital for comprehending its progression and implications for eye health.
Causes & Symptoms
Clinical Causes: Chronic elevated intraocular pressure due to ongoing issues with fluid drainage Progression of untreated or poorly managed open-angle glaucoma Neovascular glaucoma caused by abnormal blood vessel growth Trauma or injury leading to damage of the eye's drainage system Advanced angle-closure glaucoma when the drainage angle becomes completely blocked Inflammatory conditions or secondary causes like tumors influencing eye pressure
Key Symptoms: Sudden and severe visual loss in the affected eye Absence of pain or discomfort typical in earlier stages Decreased or no perception of light (vision completely lost) Large or cloudy cornea due to edema Dilated pupil that reacts poorly to light Signs of eye atrophy or shrinkage in advanced stages
Diagnostic & Treatment
Diagnosis Path: Diagnosing absolute glaucoma involves comprehensive eye examinations. An eye care professional will assess intraocular pressure through tonometry, observe the optic nerve health via ophthalmoscopy, and measure visual acuity. Additional tests such as gonioscopy to examine the anterior chamber angle and visual field testing help determine the extent of nerve damage and vision loss. Since absolute glaucoma indicates advanced disease, prompt diagnosis is crucial to differentiate it from other causes of vision loss.
Treatment Protocols: Surgical procedures such as trabeculectomy or advanced drainage device implantation to reduce intraocular pressure Laser surgeries like laser trabeculoplasty if some residual drainage capacity exists Management of underlying conditions contributing to increased eye pressure Palliative measures to protect the eye and comfort, especially if vision cannot be restored
