title: Submacular Parasite Masquerading as Posterior Pole Granuloma.
abstract: Parasites enter the eye through hematogenous spread. The interaction with host immune system may result in its destruction but not without collateral damage to the vital retinal structures. Currently, the accepted treatment for ocular parasitosis is surgical removal or direct laser photocoagulation. A 24-year-old Indian woman presented with abrupt painless loss of vision to 5/300. A large yellow-white lesion centered at macula was observed with associated retinal and subretinal hemorrhage and neurosensory retinal detachment. A parasite was seen protruding at the center of the lesion. Fluorescein angiography demonstrated disc leakage and vessel wall staining. Ultrasonography demonstrated a highly reflective subretinal lesion with aftershadowing. Serological test was positive for anti-cysticercus (IgM) antibody. Treatment with prednisolone and albendazole resulted in resolution of the lesion within 2 months with improvement of visual acuity to 20/400. A noncystic form of subretinal cysticercosis is likely with suggestive B-scan ultrasonography and serological investigations.
