Abstract

Purpose:

a) To identify commonly reported optical coherence tomography (OCT) features of ocular cysticercosis

b) To validate OCT markers of cysticercosis with observer variation

Methods: A comprehensive literature review was done for available OCT images of ocular cysticercosis. Relevant OCT images were systematically reviewed to ascertain diagnostic and prognostic features of ocular parasite. Common OCT features were enlisted and evaluated by 3 observers. Triple masking was done and observer variation was determined.

Results: Hyper reflective cyst wall (85.7%), hyper reflective scolex (85.7%) and hypo reflective clear cyst cavity (92.9%) are most consistent diagnostic features with minimal observer variation. There is a very high observer variation for prognostic tissue markers.

Conclusion: OCT features of cysticercosis can be used as a surrogate of histopathology. This obviates the need for conventional biopsy, and such cases may be appropriately managed with in vivo cyst lysis.
