IN Britain, ocular involvement by Toxocara was first recognized by Ashton (1960), who reported four -qses of granulomatous lesions of the retina due to this ascarid nematode, common in dogs and cats. Stimulated by these revelations, attention has since been focused on this aspect of ophthalmology and it appears that some ocular lesions caused by Toxocara have in the past been attributed mistake...

BACKGROUND Infestation by Demodex spp. in the palpebral edge follicles in humans is common. However, these mites are not routinely diagnosed in patients with or without ocular pathologies in Chile and their relevance is unclear. One of the eye diseases most related to infestation by Demodex spp. is blepharitis, a chronic inflammation of the eyelid margin with intermittent exacerbations, which i...

Infestation of the living tissues of the eye, ocular adnexae or orbit by larvae of flies of the order Diptera is known as ophthalmomyiasis. Ophthalmomyiasis externa is a limited superficial infestation of external ocular structures such as conjunctiva and adnexae. A case of follicular carcinoma thyroid with orbital metastasis presenting as ophthalmomyiasis externa is reported. The patient prese...

Cysticercosis, a parasitic tissue infestation caused by larval cysts (cysticercus cellulosae) of the pork tapeworm, Taenia solium, most commonly affects the central nervous system, subcutaneous tissue, skeletal muscle, heart muscle, and the eye. Ocular adnexal infestation in cysticercosis can involve various sites within the eye like vitreous humor, subretinal tissue, extraocular muscle, and la...

Sir, Myiasis is the infestation of human body tissues by Diptera larvae. Clinically myiasis can be classi¢ed according to the part of the body a¡ected. Cutaneous myiasis includes wound myiasis, creeping eruption and furuncular myiasis in which the larvae penetrate and develop within the skin. The £ies responsible for cutaneous myiasis belong to several groups (Table I). Other £ies are responsib...

Cysticercosis is a condition in which a human acts as the intermediate host of Taenia solium, a pork tapeworm. The larvae infestation sites frequently include cerebral tissue, ocular organs, and muscles. The present case report describes a rare incidence of cysticercosis in the oral region.

INTRODUCTION The pathologic relevance of Demodex infestation in blepharitis is still controversial. The aim of the study was to determine the prevalence of Demodex spp. in eyelash follicles and its relationship to eye symptoms. MATERIAL AND METHODS A total of 290 individuals were studied for the presence of Demodex folliculorum and Demodex brevis within eyelash follicles. Participants belonge...

BACKGROUND Cysticercosis is common in endemic countries like India. It can have various clinical manifestations depending on the tissue involved. It refers to a parasitic infestation by Cysticercus cellulosae, the larval form of the pork tapeworm or Taenia solium. OBJECTIVE To report an unusual case of ocular cysticercosis involving the levator palpebrae superioris and superior rectus muscle ...

Parasitic infestations of the external eye are uncommon and more often prevalent in tropical and developing countries. We present three cases with ocular infestation caused by three different arthropods admitted to the ophthalmology department of a tertiary health care centre during two months. The first case was infected with the larvae of Oestrus ovis, the second case with Phthiriasis palpebr...
