B58.01
Toxoplasma chorioretinitis
Clinical Classification Guidelines
Medical Intelligence & Overview
Toxoplasma chorioretinitis is an eye condition caused by the parasite Toxoplasma gondii. It involves inflammation of the choroid and retina, which are critical components of the eye responsible for vision. This condition can lead to vision problems if not diagnosed and managed properly. It is considered an opportunistic infection, often affecting individuals with weakened immune systems, but it may also occur in healthy people. The condition is classified under the ICD-10 code B58.01, helping healthcare professionals accurately document and manage cases related to this parasitic eye infection.
Causes & Symptoms
Clinical Causes: Infection with Toxoplasma gondii, a parasite often transmitted through contaminated food, water, or soil. Consumption of undercooked or raw meat containing Toxoplasma cysts. Ingestion of contaminated vegetables or fruits that haven't been properly washed. Contact with cat feces, which can harbor the parasite, especially for individuals handling litter boxes or soil. Congenital transmission, where the infection passes from mother to fetus during pregnancy. Reactivation of a latent infection in immunocompromised individuals, such as those with HIV/AIDS or undergoing immunosuppressive therapy.
Key Symptoms: Blurred or decreased vision in affected eye(s). Floaters or spots seen in the field of vision. Eye pain or redness, particularly if inflammation involves the uvea. Sensitivity to light (photophobia). Swelling or inflammation of the retina and choroid, which may be observed upon eye examination. Possible no symptoms in early stages, making regular eye check-ups important for at-risk individuals.
Diagnostic & Treatment
Diagnosis Path: Comprehensive eye examination, including funduscopy to visualize retinal inflammation. Serologic tests to detect Toxoplasma-specific antibodies (IgG and IgM), indicating past or recent infection. Optical coherence tomography (OCT) to assess retinal structure and inflammation. Blood tests and PCR (polymerase chain reaction) analysis of ocular fluids may be used in certain cases. Dilation of the pupil to facilitate a thorough examination of the retina and choroid.
Treatment Protocols: Antiparasitic medications such as pyrimethamine combined with sulfadiazine, along with corticosteroids to control inflammation. Use of topical or systemic steroids may be prescribed to reduce ocular inflammation. Regular monitoring by ophthalmologists to assess response to treatment and prevent complications. Managing underlying immunosuppressive conditions to reduce the risk of reactivation. In some cases, laser therapy might be used to treat retinal lesions or prevent further damage.
