Onchocerciasis, also known as river blindness, is a disease caused by infection with the parasitic worm Onchocerca volvulus. Symptoms include severe itching, bumps under the skin, and blindness. It is the second-most common cause of blindness due to infection, after trachoma.. The parasite worm is spread by the bites of a black fly of the Simulium type. Onchocerciasis, or river blindness, is a neglected tropical disease (NTD) caused by the parasitic worm Onchocerca is transmitted through repeated bites by blackflies of the genus disease is called river blindness because the blackfly that transmits the infection lives and breeds near fast-flowing streams and rivers, mostly near remote rural villages.

Snake Venom Ophthalmia. a biographical profile of Harold Ridley was included in a book called Saving Sight: ↑ "Ocular Onchocerciasis Including an Investigation in the Gold Coast". Onchocerciasis is an infection caused by the nematode Onchocerca volvulus. Humans acquire onchocerciasis through the bite of Simulium blackflies (see image below). [1, 2, 3] Because the fly develops and breeds in flowing water, onchocerciasis is commonly found along rivers and is sometimes referred to as river blindness.

This monograph has been written by an ophthalmic surgeon who has recently served with the forces in West Africa. He there availed himself of an opportunity to investigate the eye lesions resultant on Onchocerca volvulus infestation of man in an area where these are known to occur.
The author regards ocular onchocerciasis as more terrible in its effects than the far more widespread by: Ridley carried out ophthalmic examinations on natives of Funsi, an inland village in the Gold Coast.
Ocular onchocerciasis was diagnosed in 51 cases, of which 14 were blind and 8 had defective vision. ' The disease was manifested by one or more of the following conditions: corneal opacity, iridocyclitis, mass in anterior chamber, choroido-retinal degeneration and optic by: Writing as Major Harold Ridley, he published in a short paper in the British Journal of Ophthalmology on spitting snakes and an account on the composition and action of snake venom in general.
From his own experiences in the Gold Coast, Ridley described snake venom ophthalmia in a year-old labourer named Gogi Kumasi who was cutting grass when a Black-necked cobra raised Born: Nicholas Harold Lloyd Ridley, 10 July. Dermatologic and ocular manifestations.
Human involvement includes both dermatologic and ocular disease. Skin manifestations have been well described by Murdoch et al.7 These include acute and chronic papular onchodermatitis, scratch marks, lichenification, and typical pigmentary skin changes known as leopard skin. Major ocular findings in onchocerciasis include corneal changes, such as Cited by: An emerging ophthalmic parasite of the Southwestern USA (NM, CO, AZ, UT, NV and southern CA) Steve Dugan, DVM, MS, Diplomate of the ACVO Canine ocular parasites, although uncommon, do occur and the three most common are Thelaziasis, Dirofilariasis, and Onchocerciasis.

Human infection is caused by O. volvulus, with heavy infestations usually being characterized by subcutaneous nodules (onchocercomas) containing tangled masses of adult worms, a persistent dermatitis, lymphadenitis, and ocular lesions related to the invasion and death.
Onchocerciasis is a tropical disease caused by the filaria Onchocerca volvulus, whose vectors are particular species of the fly Simulium. Several other species of Onchocerca are known to affect cattle and horses.
Although onchocerciasis is a systemic infection, the manifestations of the disease are most prominent in the skin and : Y. Yassur, I. Ben Sira. Onchocerciasis, or river blindness, is a major tropical parasitic infection caused by the filarial worm, Onchocerca volvulus.
The first manifestation of infection is usually intense pruritus, and subsequently a wide variety of skin and eye changes develop, with ocular damage being the most serious complication. Ocular involvement provides the common name associated with onchocerciasis, river blindness, and may involve any part of the eye from conjunctiva and cornea to uvea and posterior segment, including the retina and optic nerve.
 The microfilariae migrate to the surface of the cornea. Punctate keratitis occurs in the infected area.

Onchocerciasis, commonly known as river blindness, is a vector-borne disease that affects millions of people in Africa, the Middle East, and South and Central America.
This disease is caused by the filarial parasitic nematode Onchocerca volvulus, which is transmitted by the blackfly vector Simulium, which carries third-stage larvae.
