[Ophthalmological screening via a hospital boat: field study for planning future health care services in remote villages at the Volta Lake in Ghana].

Background: A maiden voyage on a hospital boat was carried out to determine the spectrum of ophthalmological diseases in a rural and secluded area on the Volta Lake in Ghana in order to improve future health care services.

Patients And Methods: Portable water, electricity, and an operating theatre were available on the hospital boat. Visual acuity was determined using Snellen E charts, and Lea boards were used in children up to the age of 4 years.

Prevalence of blindness in people over 40 years in the volta region of ghana.

SummaryIn 2001, we conducted a population-based cluster survey of the prevalence of blindness and glaucoma in three districts of the Volta region of Ghana, West Africa.

The target population consisted of 2400 adults, aged 40 years and older, of whom, 2298 (95.

Onchocerciasis: a potential risk factor for glaucoma.

Background: Onchocerciasis is a microfilarial disease that causes ocular disease and blindness. Previous evidence of an association between onchocerciasis and glaucoma has been mixed. This study aims to further investigate the association between onchocerciasis and glaucoma.

Diode laser transscleral cyclophotocoagulation as a primary surgical treatment for primary open-angle glaucoma.

Objectives: To evaluate the feasibility of diode laser transscleral cyclophotocoagulation (TSCPC) as a primary surgical treatment for primary open-angle glaucoma and to compare 2 laser energy settings used for treatment.

Methods: In a prospective clinical trial in Cape Coast and Accra, Ghana, 1 eye of each of 92 patients with primary open-angle glaucoma was treated by diode laser TSCPC as a primary surgical treatment. Eyes were randomly assigned to receive treatment by 20 applications of either 1.
