Ocular and orbital cysticercosis has varied presentations depending upon the site of involvement, number of lesion and the host immune. Ocular cysticercosis may be extraocular (in the subconjunctival or orbital tissues) or intraocular (in the vitreous, subretinal space, or anterior. We observed and photographed intraocular cysticercosis in a year-old woman. . 24Moragrega, E.A. Diagnostico de cisticercosis ocular con ultrasonido.

The optic second cranial nerve is the nerve of sight, and it extends from the eye to the optic chiasm. A contribution to surgical treatment of intraocular cysticercosis. In the ocular fundus, a neuroretinitis-like picture was seen. The clinical findings may occasionally be non-specific and hence, non-diagnostic.

As long as the cyst is live, the anterior chamber reaction is absent or minimal. Without treatment for intraocular parasites, the eyes go to the blindness in a short period of time. In the primary position looking straight ahead cisticercosiis, the superior rectus muscle’s primary function is elevation, although it also contributes to intorsion and adduction.

Extraocular muscle cysticercosis-a clinical challenge to the ophthalmologists. Fluorescein Angiography is useful in delineating the sub-retinal cyst located in the periphery of the retina.

Management of Subretinal Cysticercosis – American Academy of Ophthalmology

The eye is lost with massive inflammation. Stool examination for the adult worm may be performed in cases of suspected cysticercosis. It must take into account other processes that mimic the orbital cysticercosis in their differential diagnosis.

In some South African provinces where it was seen before, it does exist at the present moment, and infestation of extraocular muscle remains exceedingly rare; but because of the versatility of the presentation, cysticercosis still should be considered in the differential diagnosis of many orbital disorders, especially in an endemic region and extraocular muscle cysticercosis should be considered in the differential diagnosis of recent acquired motility disorder or proptosis.

Indirect ophthalmoscopy should be repeated to confirm that the parasite had not moved. In Brazil, the prevalence in autopsies varies from 0.

Posterior Segment Cysticercosis In the posterior segment of the eye, vitreous cysts are more common than retinal or subretinal cysts and the inferotemporal subretinal cyst is most frequently encountered [26]. A dying cysticercosis cyst can incite a severe inflammatory response, due to the leakage of the toxins from the micro perforations present in the cyst wall [4].


It is a skeletal muscle. Inflammatory reaction can be present even with living parasite, and more so with vitreous cysts than subretinal cysts. The primary action is extorsion; secondary action is elevation; tertiary action is abduction i. The surgical treatment is the best choice in intraocular cysticercosis while medical treatment is the best choice for extraocular presentations including the extraocular cisticercoais cysticercosis.

Likewise neurologically, the muscle innervation by the inferior branch of cranial nerve III makes isolated paralysis extremely uncommon. The inferior rectus muscle was commonly involved in one study. Of all the extraocular muscles supplied by the oculomotor nerve, the inferior oblique muscle is less likely to become paralyzed.

Beri et al [33] first icular this procedure through a single 3 mm supero-temporal incision. Another two patients from our series presented horizontal diplopia secondary to abducens palsy, headache and chronic seizure disorder came to Neurology clinic and CT scans of the brain confirmed intraventricular NCC 2 and subarachnoid NCC 1in both patients ELISA tests for serum antigen and Western blot were positive for T solium. Fortunately, the results of this survey were negative.

The most common signs of Brown syndrome include: Purchase access Subscribe now. Infestation of the ocular adnexa is probably through the anterior ciliary arteries. The same results were reported by others. While commonly affected by palsies of the inferior division of the oculomotor nerve, isolated palsies of the inferior oblique without affecting oocular functions of the oculomotor nerve are quite rare and can be confused with Brown syndrome.

Cysticercosis is a disease closely related to poverty in general and in particular with a poor personal hygiene and food, socio-cultural factors, environmental, education for health in the community, and also very closely related to the hygienic and sanitary conditions of each region. A scan ultrasonography shows high amplitude spikes corresponding to the cyst wall and scolex, and B scan ultrasonography shows hanging drop sign i. The different surgical modalities of surgical removal of anterior chamber cysticercosis cyst include paracentesis, cryoextraction, erysiphake extraction, extraction with capsule costicercosis and viscoexpression [33].

Both skeletal and extraocular muscles have several types of twitch fibers, but the extraocular muscles are unique, having tonically contracting fibers not found in skeletal muscle.


However, as intraocular cysticercosis may lead to severe inflammation following larval death, early surgical removal of the cyst is the treatment of choice.

Cysticercosis of the Eyelid

Isolated two or three rectus muscles according to the place the surgeon is going to do the scleral incision. In cases with proptosis, restricted motility, inflammation or cistlcercosis CT imaging must be performed to rule out any cystic intramuscular lesion with scolex.

Ocular cysticercosis may be extraocular in the sub-conjunctival or orbital tissues or intraocular in the vitreous, sub-retinal space, or anterior chamber. In years the 70s and 80s systemic cysticercosis was very common in rural areas of South Africa but ocular cysticercosis was not associated with any cksticercosis systemic features and CT suggested that some patients with ocular cysticercosis had neurocysticercosis as well, although none was reported with accompanying systemic physical signs or symptoms.

Medial rectus muscle cysticercosis The medial rectus muscle is a muscle in the orbit. Cysticercosis is a preventable and eradicable cause of blindness endemic in the Indian subcontinent, South-East Asia and other developing countries.

Conclusion The cysticercosis of the orbit is an uncommon zoonotic parasitic disease. Systemic examination showed the presence of subcutaneous nodules on the scalp, and neck. The NCC of the optic nerve is extremely uncommon and until today no more than 10 patients have been well documented.

Cysticercus is seen as a hypodense mass with a central hyperdense scolex [30]. NCC Although other zoonotic parasites Trematode have been found in the layers of the retina at longitudinal position [ ] the size and shape of cysticercus exceed the thickness of the retina so that its location is below it, and in close relation to the vascular layer of which is nourished.

Using a muscle hook passed underside and silk suture is passed around the muscle to do the fixation. Is orbital metastasis another challenger for differential diagnosis? In some series of patients with extraocular cysticercosis, the superior rectus muscle is the most commonly affected
