Summary
Ophthalmologists are increasingly seeing Loa loa eye infections in non-travelers. Early diagnosis and treatment are crucial for this parasitic worm infestation.
Area of Science:
- Ophthalmology
- Infectious Diseases
- Parasitology
Background:
- Loa loa infestation, or loiasis, is a parasitic disease endemic to West Africa.
- Ocular manifestations can occur, presenting diagnostic challenges in non-endemic regions.
Observation:
- Three cases of Loa loa infestation presented to ophthalmology departments in the South West Thames region over 12 months.
- Patients had a history of travel to West Africa, with adult worms surgically removed.
Findings:
- Confirmed adult Loa loa nematodes required referral to infectious diseases specialists for treatment.
- The cases highlight the increasing frequency of ocular loiasis in European ophthalmology practices.
Implications:
- European ophthalmologists, especially in ethnically diverse areas, must consider loiasis in patients with unexplained eye symptoms.
- Lack of recent travel history should not exclude loiasis from the differential diagnosis in at-risk individuals.
- Increased awareness is vital for timely diagnosis and management of this neglected tropical disease.

01:28Angle Closure Glaucoma: Treatment
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...
01:27Open Angle Glaucoma: Treatment
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.

01:25Glaucoma: Overview
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...
01:30Leishmaniasis
Leishmaniasis is a protozoal disease caused by species of the genus Leishmania and transmitted through the bite of infected female sandflies. The parasite exists in two principal morphological forms during its life cycle. A sandfly acquires intracellular amastigotes from an infected reservoir host, such as a dog. Within the sandfly, these forms differentiate into motile, flagellated promastigotes. During a subsequent blood meal, promastigotes are injected into the human host, where they...
