H18.06
Stromal corneal pigmentations
Clinical Classification Guidelines
Inclusion Terms
- Hematocornea
Medical Intelligence & Overview
Stromal corneal pigmentations, classified under ICD-10 code H18.06, refer to the buildup of pigment within the stroma, the thick middle layer of the cornea. These deposits can affect the clarity of the cornea, potentially impacting vision. The condition is sometimes associated with hematocornea, a rare abnormality characterized by blood within the corneal layers, which can contribute to pigment accumulation. Although often asymptomatic, some individuals may notice visual disturbances or changes. Proper diagnosis and management are essential to prevent potential complications and preserve visual function.
Causes & Symptoms
Clinical Causes: Presence of abnormal blood vessels in the cornea (neovascularization) Previous corneal trauma or injury leading to bleeding within the cornea Inflammatory eye conditions such as keratitis Degenerative corneal diseases Hematocornea, where blood accumulates in the corneal layers Chronic eye infections or inflammations Certain systemic conditions that affect blood vessels
Key Symptoms: Blurred or decreased vision Presence of pigmented spots or deposits on the cornea Sensitivity to light (photophobia) Redness or inflammation of the eye Discomfort or a foreign body sensation Possible eye redness or swelling
Diagnostic & Treatment
Diagnosis Path: Diagnosis typically involves a comprehensive eye examination by an ophthalmologist, which includes slit-lamp biomicroscopy to visualize pigment deposits within the cornea. Additional tests, such as corneal topography, anterior segment optical coherence tomography (AS-OCT), or fluorescein staining, may be utilized to assess the extent of pigmentation and underlying conditions. Medical history and thorough examination help differentiate stromal corneal pigmentations from other corneal abnormalities. In cases associated with hematocornea, identifying blood within the corneal layers is essential for accurate diagnosis.
Treatment Protocols: Monitoring and observation in mild cases where vision is not significantly affected Treating underlying conditions such as infections or inflammations Laser procedures to remove pigment deposits in certain cases Corneal transplantation or keratoplasty if corneal clarity is significantly compromised Addressing vascularization with medications or surgical interventions to reduce new blood vessel growth Use of anti-inflammatory eye drops or medications to control inflammation
