This is the most common helminth to produce CNS infection in human beings (neurocysticercosis).1 Ocular cysticercosis may be extraocular (in the sub-conjunctival or orbital tissues) or intraocular (in the vitreous, sub-retinal space, or anterior chamber).2 Ocular manifestations of cysticercosis vary from asymptomatic to painful blind eye and may be associated with neurological symptoms such as headache and fits. The most common site of localisation reported in western studies is posterior segment and in Indian literature the ocular adnedxa.3 We report a case of orbital neurocysticercosis to document the characteristic involvement of orbit and CNS. A 17 years old patient reported to us in eye OPD with headache for 3 months, diminution of vision and double vision since 15 days. On thorough clinical evaluation in central nervous system examination the patient had positive cerebellar signs of ataxia, past pointing, intention tremors and dysdiadochokinesia. The patient also had motor system involvement leading to bilateral lower limbs weakness consistent with brain stem lesions. On ocular examination the patient had 6/6 vision in right eye and 6/24 in left eye. Ocular motility testing showed left abduction deficit with horizontal diplopia on levoversion (Figure a,b,c). The anterior and posterior segments including the fundus examination of both the eyes were normal. Blood investigations in the form of complete blood count, blood sugar (fasting and postprandial) were normal. X ray chest (PA view) was within normal limits. On CT scan multiple ring enhancing lesions involving bilateral cerebral hemisphere, cerebellum and brain stem with ring enhancing lesion in lateral rectus of left eye (Figure 1-4).
