H44.20
Degenerative myopia, unspecified eye
Clinical Classification Guidelines
Medical Intelligence & Overview
Degenerative myopia, also known as pathologic or progressive myopia, is a serious eye condition characterized by an elongation of the eyeball. This abnormal growth leads to worsening nearsightedness and can cause damage to various parts of the eye. When classified under ICD-10 code H44.20, it is noted as an unspecified eye condition related to this degenerative process. This condition often develops gradually and can affect vision quality significantly over time, sometimes resulting in complications such as retinal detachment or macular degeneration.
Causes & Symptoms
Clinical Causes: Genetic predisposition: A family history of myopia can increase the risk. Environmental factors: Extensive near work, prolonged screen time, or insufficient outdoor activity may contribute. Structural eye changes: Excessive elongation of the eyeball during growth stages. Metabolic or connective tissue disorders: Certain systemic conditions that weaken the eye's structural integrity.
Key Symptoms: Progressive difficulty seeing objects at a distance. Blurred or distorted vision, especially in advanced stages. Perception of increased nearsightedness over time. Possible visual distortions or appearance of dark spots in the central vision. In cases with complications: flashes of light, floaters, or a shadow or curtain over the visual field.
Diagnostic & Treatment
Diagnosis Path: Assessment primarily involves a comprehensive eye examination, including refraction tests to measure degree of myopia and slit-lamp examination to evaluate eye structures. Optical coherence tomography (OCT) and fundus photography can help detect morphological changes, such as elongation of the eye or signs of degeneration in the retina or choroid. When degeneration signs are present, further evaluation may involve fluorescein angiography to observe blood flow in retinal vessels. Accurate diagnosis depends on recognizing the progressive nature of the condition and identifying potential complications.
Treatment Protocols: While degenerative myopia cannot be reversed, management strategies aim to slow progression and address complications. Recommendations include regular eye examinations to monitor changes and early signs of complications. Corrective lenses (glasses or contact lenses) help optimize vision, while low vision aids may assist in daily activities. For advanced cases with retinal detachment or other serious issues, surgical intervention might be necessary. Additionally, patients are encouraged to protect their eyes from trauma and minimize risk factors that could exacerbate degeneration, such as excessive near work or poor lighting. In some cases, treatments like laser therapy or vitreoretinal surgery are used to treat specific complications.
