H44.2A9
Degenerative myopia with choroidal neovascularization, unspecified eye
Clinical Classification Guidelines
Medical Intelligence & Overview
Degenerative myopia, also known as pathological or high myopia, is an advanced form of nearsightedness characterized by elongation of the eyeball and degenerative changes in the eye tissue. When this condition involves choroidal neovascularization—growth of abnormal blood vessels beneath the retina—vision can become severely impaired. The ICD-10 code H44.2A9 specifically refers to this degenerative myopia with choroidal neovascularization in an unspecified eye, highlighting the seriousness of this eye condition and the potential for vision loss if left untreated.
Causes & Symptoms
Clinical Causes: Genetic predisposition to high myopia and degenerative ocular changes Progressive elongation of the eyeball leading to tissue degeneration Abnormal growth of new blood vessels beneath the retina, often stimulated by degenerative changes Environmental factors such as extensive near work or limited outdoor activity during childhood Age-related degeneration affecting the retinal and choroidal tissues
Key Symptoms: Blurred or distorted central vision Presence of dark or blank spots (scotomas) in the visual field Perception of straight lines as wavy or bent (metamorphopsia) Sudden increase in visual distortion or vision loss Visual disturbances like flashes of light or a sudden increase in floaters
Diagnostic & Treatment
Diagnosis Path: Visual acuity testing to assess the sharpness of vision Dilated fundus examination to visualize retinal and choroidal changes Optical coherence tomography (OCT) to capture detailed cross-sectional images of the retina Fluorescein angiography to detect and evaluate abnormal blood vessel growth Progressive monitoring of the eye’s axial length and degenerative changes over time
Treatment Protocols: Anti-vascular endothelial growth factor (anti-VEGF) injections to inhibit abnormal blood vessel growth and reduce leakage Photodynamic therapy (PDT) involving light-activated drugs to selectively destroy neovascular tissue Laser photocoagulation to seal off abnormal vessels, although less commonly used today due to potential damage to surrounding tissues Regular monitoring and follow-up examinations to detect changes early Corrective lenses or low vision aids to optimize remaining vision

Documentation
How do I report H44.2A9?
Clinical documentation must specify the nature of Degenerative myopia with choroidal neovascularization, unspecified eye and any associated comorbidities for accurate reporting.
