Ophthalmologisches Screening mit einem Hospitalschiff

Feldstudie zur strategischen Planung der zukünftigen augenärztlichen Versorgung in abgelegenen Dörfern am Voltastausee in Ghana

Ophthalmological screening via a hospital boat

Field study for planning future health care services in remote villages at the Volta Lake in Ghana

Zusammenfassung

Hintergrund

Es wurde eine augenärztliche Feldstudie mit einem Hospitalschiff auf dem Voltastausee in Ghana durchgeführt, um zu ermitteln, in welchem Umfang dort augenärztliche Untersuchungen und operative Versorgung möglich sind.

Patienten und Methoden

Das Hospitalschiff ist mit einem Operationssaal, Elektrizität und sauberem Trinkwasser ausgerüstet. Sehtests erfolgten mit Snellen-Einzel-E-Haken. Bei Kindern bis zum 4. Lebensjahr wurden Lea-Tafeln verwendet. Die vorderen Augenabschnitte wurden mittels Handspaltlampe und der Fundus binokular in Mydriasis untersucht. Augeninnendruckmessungen erfolgten mit dem Perkins-Handapplanationstonometer.

Ergebnisse

1246 Bewohner wurden untersucht. Das Durchschnittsalter betrug 23,7 Jahre und die mittlere Sehschärfe für beide Augen 1,0 (log MAR 0,0±0,3). Die Haupterblindungsursache ist die Katarakt mit 45,8%, gefolgt von Optikuspathologien mit 29,2%.

Schlussfolgerung

Das Hospitalschiff eignet sich gut zum Screening und zur Durchführung von kleinen Eingriffen. Intraokulare Eingriffe wären aus technischer Sicht auf dem Hospitalschiff durchführbar, sinnvoller erscheint jedoch die Versorgung im nächstgelegenen Krankenhaus.

Abstract

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. The anterior segments were examined using hand held slit lamps. After pupil dilation indirect binocular ophthalmoscopy was performed and tonometry was carried out using a Perkins tonometer

Results

A total of 1,246 citizens were examined. The mean age was 23.7 years and the mean visual acuity was 6/6 (log MAR 0.0±0.3. The main cause of blindness was a cataract with 45.8%, followed by pathological conditions of the optic disc with 29.2%.

Conclusions

The hospital boat is suitable for screening and for carrying out minor extraocular operations. Looking just at the technical aspect, it is possible to perform major intraocular operations on the hospital boat. However, due to the lack of immediate follow-up visits, it is advisable to carry out major operations in the next eye clinic on shore.
