A Case of Associated Ophthalmo-Neurocysticercosis

Orbital and adnexal cysticercosis

“…This may be due to the course of the ophthalmic artery, which after giving off lacrimal branches, runs along the medial side of the orbit and divides into the terminal branches. 32,42,69 Association of systemic cysticercosis with orbital cysticercosis is rare, as may be seen from the data published in the literature. In some patients with orbital cysticercosis, associations with subcutaneous cysticercosis 5 and neurocysticercosis 5,6,41,70,71 have been found.…”

“…The parasites are finally deposited at a place where the capillaries are narrow and the circulation sluggish. They settle wherever there is a difference in the blood supply and its pressure at the limit of separation of two areas, the higher pressure in the blood vessels producing effarction of the parasite from the capillaries 1,32,42,69 . Inside the orbit, the nasal side is involved more frequently.…”

The Uvea

“…A new case of chorio¬ retinitis with histologie confirmation has been reported.9 Intraocular cysticercosis is usually subretinal or vitreal but may affect other areas including the optic nerve. 10 An aqueous tap11 has revealed 50% eosinophils and may be helpful in the diagnosis of intra¬ ocular cysticercosis. In the young child a complement fixation test for cytomegalic in¬ clusion disease is of value from the ages of 5 to 24 months since the child has lost his passive antibodies and has very little chance to pick up an unrelated infection.12 A for¬ eign body such as a weed may pierce the cornea and result in a fungal iritis.13 A tattoo with cobaltous aluminate may pro¬ duce a granulomatous hypersensitivity syn¬ drome14 which results in a purulent dis¬ charge from the light blue areas of the tattoo and a granulomatous anterior uveitis.14 In glaucomatocyclitic crises the attack is uni¬ lateral, recurrent, and typified by a dilated instead of a contracted pupil.…”
