In cases of extraocular muscle involvement Figure 2 superior rectus muscle is the most common site [14]. Because the inferior oblique is innervated near its middle, it may be weakened either proximal or distal to its point of innervation.

Only six patients all from India have been reported in the medical literature, they had between 9 and 23 years of age and most of some of them complained of unilateral ptosis, inflammation of the upper eyelid and restricted ocular motility while another complained of mild upper eyelid discomfort without display or decreased vision and no lid erythema or edema plus full extraocular movements in all directions of gaze.

The incision should extend more than two thirds of the scleral thickness to have a floor for the placement of the diathermy treatment to avoid bleeding trans operators.

Patients with congenital Brown syndrome rarely complain of diplopia, because most patients have developed suppression. Multiple cysts in the same eye at different locations may be present [32].

Cysticercosis of the eye

In our experience, an isolated paralysis of the medial rectus muscle due to cysticercosis without involvement of other muscles is very uncommon.

The subretinal organism eventually develops into a cyst and the parasite and its movements can be recognized through the thin muscular layers.

When the parasite is freely mobile it may contribute to the absence of reaction in the anterior chamber. Adjacent soft-tissue inflammation may be present Figure 4. The choroid is exposed and obvious blood vessels cauterized.

Cysticercosis of the eye

My father, my sisters, nephews, nieces, aunts, uncles, cousins and almost all members of my family contributed to this project cidticercosis one way or another – to all of them: Please review our privacy policy. It is well known that cysticercosis of the extraocular musculature is rare and within this group the affectation of the eyelid is about 0. Systemic cysticercosis should be ruled out especially neurocysticercosis with the adequate neurosurgical examination and management of the same, as it would require anthelminthic therapy with steroid cover after intracameral cyst removal.

Vitreous cysticercosis and anterior chamber cysticercosis 2.

In this series of patients because of the severity of the lesions, surgical removal, although partly successful, did not improve vision and the distribution of the cysts in the various structures of the eye was similar to cases reported in the literature. There are two muscle fiber layers in the medial and lateral recti. From their review of the medical literature they found that up to1 cases of ocular cysticercosis were reported and when studied their patients most ocylar them were occasional and came to South Africa from India.

Ultrasonography is an effective and economical alternative to MRI and CT for the detection of the intra-ocular cysticerci. Taenia solium produces two different diseases: Eventually, the larvae die and are either totally resorbed or calcified.

An unusual cistucercosis of multiple brain neurocysticercosis with ocular cysticercosis involving levator palpebrae superioris and superior rectus muscle has been reported [16]. The common causes of inferior oblique muscle dysfunctions are facial trauma, endoscopic ethmoidectomy, superior oblique muscle palsy overaction of the inferior oblique muscleunilateral inferior oblique anterior transposition.

While many vertical deviations that appear to be due cisticegcosis an inferior oblique palsy based on the results of the three-step test may be caused by inferior oblique weakness, skew deviation should also be considered in any patient with a history of head trauma, or other neurological findings.

The orbits are two bony cavities occupied by the eyes and associated muscles, nerves, blood vessels, fat, and much of the lacrimal apparatus. The medial rectus is said to insert in the normal eye 5. This portion inserts on the skin of the upper eyelid, as well as the superior tarsal plate. Human beings are cisticrecosis hosts that harbor the adult parasite in the intestine and pigs are the intermediate hosts harboring the larvae.
