H40.842
Neovascular secondary angle closure glaucoma, left eye
Clinical Classification Guidelines
Medical Intelligence & Overview
Neovascular secondary angle closure glaucoma is a serious eye condition characterized by abnormal blood vessel growth that leads to increased intraocular pressure, potentially damaging the optic nerve and impairing vision. When this condition affects the left eye, it can result in significant visual difficulties if not diagnosed and managed promptly. This guide provides an overview of what this diagnosis entails, including its causes, symptoms, how it is diagnosed, and available treatment options.
Causes & Symptoms
Clinical Causes: Proliferative diabetic retinopathy, which causes abnormal blood vessel growth in the eye Central retinal vein occlusion, leading to ischemia and neovascularization Inflammatory eye diseases that stimulate new vessel formation Tumors or other ocular conditions promoting abnormal blood vessel growth Long-standing retinal ischemia from various eye conditions
Key Symptoms: Sudden or gradual loss of vision in the left eye Blurred vision or haziness Seeing flashes of light or floaters Persistent or increasing eye redness Eye pain or headache around the affected eye Hazy or cloudy appearance of the front part of the eye
Diagnostic & Treatment
Diagnosis Path: Measurement of intraocular pressure to detect elevated pressure Slit-lamp examination to observe the anterior segment of the eye Gonioscopy to assess the drainage angle for blockage Fundus examination to visualize blood vessels in the retina Imaging tests such as fluorescein angiography or optical coherence tomography (OCT) to evaluate retinal and choroidal blood vessels and identify neovascularization
Treatment Protocols: Anti-VEGF injections to inhibit neovascularization Laser photocoagulation to seal abnormal blood vessels and reduce ischemia Medications such as eye drops to lower intraocular pressure Systemic treatments addressing underlying conditions like diabetes Surgical procedures in advanced cases to facilitate eye pressure relief and prevent further damage
