H33.123
Parasitic cyst of retina, bilateral
Clinical Classification Guidelines
Medical Intelligence & Overview
Parasitic cysts of the retina are abnormal, cyst-like structures caused by parasitic infections that affect the eye's retina, the light-sensitive tissue at the back of the eye. When these cysts occur in both eyes simultaneously, they are classified as bilateral. This condition can impair vision and requires proper medical assessment to determine the best course of action.
Causes & Symptoms
Clinical Causes: Infection by parasitic organisms, most commonly Toxocara spp., which are roundworms often originating from infected dogs or cats. Transmission through ingestion of contaminated food or water containing parasite eggs. In nearby environments where exposure to contaminated soil or contaminated animals is common. Rare cases involve other parasites capable of infecting ocular tissues, such as cysticercosis caused by Taenia solium larvae.
Key Symptoms: Blurred or decreased vision in one or both eyes. Floaters or spots drifting across the field of vision. A visible cyst or abnormal mass within the retina upon eye examination. Eye discomfort or mild pain in some cases. Sensitivity to light (photophobia). Possible redness or swelling around the eye if inflammation occurs.
Diagnostic & Treatment
Diagnosis Path: Diagnosis typically involves a comprehensive eye examination, which may include:
Treatment Protocols: Treatment approaches depend on the size, location, and activity of the cysts, as well as the symptoms experienced. Common strategies include:
