ABSTRACT
1. Refractive errors are influential, but not essential factors in the development of squint. Hypermetropia is commonly found in cases of convergent conmitant squint; myopia, in the divergent type2. Concomitant convergent squint beings usually before the age of six years. In such cases, the fusion sense is apt to be deteriorated. In cases of squint that develops after this age, the defective fusion sense is capable of being re-educated3. Orthoptic exercises, if timely instituted, are one of the most effective treatments to correct squint. it is seldome successful if it is done after seven years of age in squints which started in early life4. Surgical intervention may restore ocular parallelism, partially or totally, and the results obtained may improve greatly if orthoptic training is given before and after surgery, especially as regards binocular vision. But, if the fusion sense is markedly deteriorated or lost, the effect of surgery is purely cosmetic. (Summary and Conclusion)
ABSTRACT
Quince casos de Edema Agudo Pulmonar de Altura (EAPA), fueron evaluados en un Hospital a 4,800 m de altitud s.n.m., presentados durante un año entre una población minera. Fueron registrados las manifestaciones clínicas y los datos epidemiológicos. Esta observación mostró que los sínstomas se presentaron más pronto en relación a lo informado en otros reportes, todos en menos de las 24 horas y la mayoría antes de las 8 horas.
