Nonsurgical management of binocular diplopia induced by macular pathology

OBJECTIVE

To treat binocular diplopia secondary to macular pathology.

METHODS

Seven patients underwent evaluation and treatment. All had constant vertical diplopia caused by various maculopathies, including subretinal neovascularization, epiretinal membrane, and central serous retinopathy. Visual acuity ranged from 20/20 to 20/30 in the affected eye. All except 1 patient had a small-angle, comitant hyperdeviation with no muscle paresis. Sensory evaluation demonstrated peripheral fusion and reduced stereoacuity. Neither prism correction nor manipulation of the refractive errors corrected the diplopia. A partially occlusive foil (Bangerter) of density ranging from 0.4 to 1.0 was placed in front of the affected eye to restore stable, single vision.

RESULTS

The Bangerter foil eliminated the diplopia in all patients. Two patients elected not to wear the foil; 1 patient was afraid of becoming dependent, and the other was bothered by the visual blur. Visual acuity in the affected eye was reduced on average by 3 lines. All patients maintained the same level of sensory fusion, with only 2 having reduced stereoacuity. Symptoms returned when the foil was removed or its density was reduced.

CONCLUSION

Low-density Bangerter foils provide an effective, inexpensive, and aesthetically acceptable management for refractory binocular diplopia induced by macular pathology, allowing peripheral fusion to be maintained.

Primary care in Cuba: low- and high-technology developments pertinent to family medicine

Cuba's accomplishments in primary care, while controversial, include several developments pertinent to family medicine. These accomplishments involve low-technology and organizational innovations such as neighborhood-based family medicine as the focus of primary care; regionalized systems of hospital services and professional training; innovative public health initiatives and epidemiologic surveillance; universal access to services without substantial barriers related to race, social class, gender, and age; and active programs in treatments such as "green medicine" and "thermalism." High-technology achievements include innovations in pharmacology and biotechnology, surgical procedures, and care of patients infected by the human immunodeficiency virus (HIV). Limited access to Cuban publications, impediments to presentations by Cuban health care professionals at professional meetings, and the prohibition on importing products of Cuban biotechnology to the United States inhibit a detached, scientific appraisal of Cuba's accomplishments. Cuba's isolation from the US clinical and research communities has prevented interchanges that would improve primary care services in both countries.

Comprehensive care and the sanatoria: Cuba's response to HIV/AIDS

The authors present an overview of Cuba's response to HIV/AIDS including: (a) the development of comprehensive health care in Cuba; (b) the epidemiology of AIDS in Cuba; (c) the sanatoria approach to treatment and recent changes; (d) the idea of comprehensive HIV/AIDS care as a basic human right; (e) the effects of the special period on the HIV/AIDS program and containment of the epidemic; and (f) a critique of Cuba's HIV/AIDS program.

Human immunodeficiency virus in Cuba: the public health response of a Third World country

This article describes Cuba's effort to develop a comprehensive program for control of its human immunodeficiency virus (HIV) epidemic. The program consists of multiple interventions, including blood donor screening, a ban on imported blood and blood products, widespread semicompulsory screening of defined and general populations, research and clinical trials on treatment and diagnostic methods, and health education in the press, radio, television, workplace, and schools. The most controversial of the program's measures has been the treatment of HIV antibody-positive persons (both asymptomatic and clinically ill) through what Cubans term a "sanatorial regimen," consisting of admission into an institutional setting where both preventive and curative treatment is offered, and where residents have limited contact with their families, neighborhoods, friends, and the rest of society. The Cuban HIV control program merits studying because of the comprehensiveness of the measures in a poor country; the special experience of screening large, mostly healthy populations; its potential contribution to understanding the natural history of the disease due to the early identification and follow-up of HIV antibody-positive individuals; and the cultural, political, and socioeconomic conditions that give rise to a different epidemiologic profile of the disease and to an apparent societal consensus on the controversial issue of institutional semiconfinement.
