Physical Examination

Skin

• Papular eruptions
• Onchocercomata (subcutaneous nodules)
• Changes in the color of the skin that result in a "leopard skin" appearance

• Thinning of the skin with loss of elastic tissue that gives the skin a "cigarette-paper" appearance and can contribute to conditions such as hanging groin..

Eyes

• Blindness: In Onchocerciasis, the most serious manifestation consists of ocular lesions that can progress to blindness

• Punctate keratitis occurs, which clears up as the inflammation subsides

• Sclerosing keratitis can occur, making the affected area become opaque. Over time the entire cornea may become opaque, thus leading to blindness.
