H44.4
Hypotony of eye
Clinical Classification Guidelines
Medical Intelligence & Overview
Hypotony of the eye, classified under ICD-10 code H44.4, is a condition where the intraocular pressure (pressure inside the eye) falls below normal levels. This drop in pressure can lead to structural and functional impairments of the eye, potentially affecting vision. Typically, normal intraocular pressure ranges between 10-21 mm Hg; when pressure drops below 6-8 mm Hg, the eye may be considered hypotonic. Recognizing and understanding this condition is essential for proper management and prevention of complications.
Causes & Symptoms
Clinical Causes: Surgical procedures on the eye, such as glaucoma surgery or cataract removal, which can inadvertently decrease eye pressure. Trauma or injury to the eye that results in leakage of fluid or damage to the eye’s structures. Inflammatory conditions within the eye, such as uveitis, causing a decrease in intraocular pressure. Use of medications like topical or systemic corticosteroids, which can influence eye pressure. Certain eye diseases that affect fluid production or outflow, leading to pressure drops. Chronic eye conditions leading to poor aqueous humor production, such as advanced degenerative changes.
Key Symptoms: Visual disturbances or blurred vision. Shifts or changes in the shape of the eyeball, which may be apparent upon examination. Potential discomfort or a feeling of fullness in the eye. In severe cases, the eye may appear soft or sagging due to decreased pressure. Possible secondary complications, like choroidal detachment or retinal issues.
Diagnostic & Treatment
Diagnosis Path: Diagnosing hypotony involves a comprehensive eye examination by an eye care professional. Key steps include:
Treatment Protocols: Managing hypotony focuses on addressing the underlying cause and restoring normal intraocular pressure to prevent damage. Typical approaches include:
