RESUMO
The prevalence of refractive errors was studied in an adult rural population. Of the 8102 eyes studied 18-4% were myopic, 57-1% were emmetropic, and 24-5% were hypermetropic. Mild myopia was commoner in males than in females, and mild hypermetropia was commoner in females than in males. There was increasing hypermetropia with increasing age, probably due to unmasked, latent hypermetropia up to the age of 70 years and to a true shift toward hypermetropia after the age of 70 years.

The prevalence of glaucoma in a rural population of 6232 people over the age of 40 years, including patients with previously diagnosed glaucoma, was found to be 1.21%. There were 41 cases of open-angle glaucoma compared to 32 cases of angle-closure glaucoma. The prevalence of glaucoma among subjects over the age of 60 years was 3.07%.

Two hundred and sixty-seven eyes which underwent peripheral iridectomy for presumed angle-closure glaucoma were investigated. The diagnosis of angle-closure glaucoma was confirmed postoperatively in 258 eyes, in 201 of which the intraocular pressure became normal without further treatment and in 57 of which the postiridectomy IOP was elevated because of visible damage to the anterior chamber angle. Three eyes had open-angle glaucoma with a narrow angle. Six eyes had possible mixed (combined mechanism) glaucoma (2-2%). Mixed glaucoma is a rare, fortuitous combination of open-angle and angle-closure glaucoma rather than a distinct entity, and it might be advisable to avoid the term, which tends to be used for primary glaucomas of uncertain classification.
