MOBILE SUBRETINAL CYSTICERCUS IMAGED BY SPECTRAL-DOMAIN OPTICAL COHERENCE TOMOGRAPHY WITH MOTION TRACKER.

PURPOSE: To report optical coherence tomography-based videoimaging of alive subretinal cysticercus along with its mobile scolex.

METHODS

Spectral-domain optical coherence tomography was used to record high-definition videoimages, using the inbuilt motion tracker, in a 12-year-old boy with history of neurocysticercosis.

RESULT: The scolex was found to be sensitive to light, and contractile movements were seen in the cyst wall and the germinative layers. The patient underwent vitrectomy, and the diagnoses were confirmed with histopathologic assessment.

CONCLUSION

Optical coherence tomography is a useful tool for diagnosing posterior segment cysticercosis. The intense motion of scolex does not impact the surrounding ocular structures.
