H21.1
Other vascular disorders of iris and ciliary body
Clinical Classification Guidelines
Inclusion Terms
- Neovascularization of iris or ciliary body
- Rubeosis iridis
- Rubeosis of iris
Medical Intelligence & Overview
Vascular disorders of the iris and ciliary body, classified under ICD-10 code H21.1, involve abnormal blood vessel growth or changes within these eye structures. One common condition in this category is rubeosis iridis, also known as neovascularization of the iris. These disorders can affect eye appearance and function, potentially leading to complications such as glaucoma or vision loss if left untreated. Understanding the causes, symptoms, and available treatments can help in managing these eye conditions effectively.
Causes & Symptoms
Clinical Causes: Diabetic retinopathy: High blood sugar levels damaging retinal blood vessels can promote abnormal vessel growth in the iris. Ocular ischemic syndrome: Reduced blood flow to the eye, often due to carotid artery disease, may trigger neovascularization. Inflammatory eye conditions: Chronic inflammation can lead to abnormal vascular growth. Eye tumors: Certain tumors can stimulate new blood vessel formation within the eye. Other retinal vascular diseases: Conditions affecting the eye’s blood vessels can extend their effects to the iris and ciliary body.
Key Symptoms: Excessive redness of the eye Visual disturbances or blurriness Increased intraocular pressure, potentially causing glaucoma Irregular pupil shape or size Presence of visible blood vessels on the surface of the iris Sensitivity to light (photophobia) Eye discomfort or aching
Diagnostic & Treatment
Diagnosis Path: Slit-lamp examination: To observe abnormal vessels or other eye structures Gonioscopy: To examine the drainage angle of the eye Fluorescein angiography: To assess blood flow and identify abnormal vessel growth Ultrasound biomicroscopy: To visualize structures behind the iris Intraocular pressure measurement: To detect secondary glaucoma
Treatment Protocols: Laser therapy: Procedures like panretinal photocoagulation to reduce abnormal vessel growth Medications: Anti-vascular endothelial growth factor (anti-VEGF) injections to inhibit new vessel formation Control of underlying conditions: Managing diabetes or blood pressure to prevent disease progression Surgical intervention: In severe cases, procedures such as vitrectomy or glaucoma surgery may be necessary Monitoring: Regular follow-up visits to assess disease progression and treatment response
