Testing the FOCOMETER--A new refractometer.

The FOCOMETER, an optometer which measures spherical refractive errors, is intended to provide rural or economically disadvantaged populations spherical prescriptions without the need for complicated protocols, expensive equipment, or electricity. FOCOMETER readings were compared with the spherical equivalent determined from autorefraction and subjective trial lens refractions in children, and with retinoscopy in adults. Over the range of refractive errors tested (-4 to +5 D) reasonably close readings, within one-half a diopter, were found for comparisons with autorefraction and retinoscopy and about one-tenth of a diopter difference was found between subjective refractions and the FOCOMETER.

Onchocerciasis and other eye problems in developing countries: a challenge for optometrists.

BACKGROUND: Onchocerciasis, also known as River Blindness, affects about 18 million people around the world, resulting in severe visual impairment or blindness for approximately 2 million. METHODS: The disease is transmitted through the bite of a tiny black fly, which breeds in fast moving rivers and streams. The fly injects immature forms of the parasite worm, Onchocerca volvulus, whose microfilariae migrate to superficial tissues, and may invade any part of the eye. In the eye, living microfilariae may be found in any ocular structure, however, sclerosing keratitis, a severe corneal involvement is the major cause of blindness from the disease. RESULTS: Substantial efforts are currently underway to control the disease in Latin America and equatorial Africa, now that an effective, nontoxic medication, ivermectin, is available. CONCLUSIONS: Optometrists are helping to solve the logistic challenges for treatment of this disease, as most onchocerciasis endemic areas are remote with difficult access.

Preference of hospital employees for work-related outcomes.

A list of five possible work-related outcomes was compiled and included in a questionnaire. This was administered to 490 employees, categorized into seven occupational groups, in three different hospitals in Manila, The Philippines. Responses were compared among work outcomes, identical occupational groups and three hospitals; the most valued outcome was established for all respondents. Findings indicate that variables apt to motivate employees depend on the occupational group to which they belong, the kind of work they perform and the type of hospital in which they work. These findings have implications for the ability of hospital administrators to motivate their employees to perform in a manner that meets expected standards.
