H21.553
Recession of chamber angle, bilateral
Clinical Classification Guidelines
Medical Intelligence & Overview
Recession of the chamber angle, bilateral, is an eye condition characterized by an abnormal positioning of the anterior chamber angle in both eyes. The anterior chamber angle is the space where the cornea meets the iris, and its proper function is vital for maintaining normal eye pressure and fluid drainage. When this angle recedes or becomes more open than usual, it can influence eye health and potentially lead to other eye conditions, such as glaucoma. This condition is classified under ICD-10 code H21.553 and requires careful assessment by ophthalmologists for appropriate management.
Causes & Symptoms
Clinical Causes: Genetic predisposition leading to anatomical variations in eye structures Anterior segment dysgenesis, involving abnormal development of the eye's front structures Previous eye injuries or surgeries that alter anterior chamber angles Progressive ocular conditions that modify eye anatomy over time Certain types of glaucoma associated with angle recession
Key Symptoms: Typically asymptomatic in early stages; may not cause noticeable symptoms Gradual vision changes or blurring if associated with increased eye pressure Seeing halos or glare under certain lighting conditions Eye discomfort or pain in some cases Redness or swelling of the eye Potential signs of increased intraocular pressure, such as headache or eye tenderness
Diagnostic & Treatment
Diagnosis Path: Slit-lamp examination to closely inspect the anterior chamber and its structures Gonioscopy, where a special lens is used to visualize the chamber angle directly Tonometry to measure intraocular pressure Optical coherence tomography (OCT) may be used for detailed imaging of the anterior segment Assessment for signs of glaucoma or other related eye conditions
Treatment Protocols: Monitoring eye pressure regularly to detect any elevation early Medications such as eye drops to lower intraocular pressure if necessary Laser procedures, like laser trabeculoplasty, to enhance fluid drainage Surgical interventions in advanced cases to alter eye structures and improve fluid flow Addressing underlying causes or associated disorders to prevent progression
