| The objective of the present study was to describe, for the first time in Brazil, the use by a non-ophthalmologist of a community-based marginal rotation procedure by a posterior approach in the indigenous population from the Upper Rio Negro basin. Seventy-three upper eyelids of 46 Indians (11 males and 35 females) with cicatricial upper eyelid entropion and trichiasis were operated in the Indian communities using a marginal rotational procedure by a posterior approach by a non-ophthalmologist physician who had general surgery experience but only an extremely short period (one week) of ophthalmic training. Subjects were reevaluated 6 months after surgery. Results were classified according to the presence and location of residual trichiasis and symptoms... |

| The Vernier acuity of 50 normal untrained subjects (20 males and 30 females) was measured by the method of adjustment. Subjects were divided into five age ranges with 10 subjects in each age group: 5-10, 11-20, 21-30, 31-40, and 41-50 years. All subjects had normal visual acuity (20/20) and volunteered to participate in the experiment. Children were selected from a local school and adults recruited from the technical staff of the Department of Ophthalmology of the School of Medicine. Vernier acuity was higher in adults compared to children. Intraindividual variability was high and it was estimated that for most individuals of all age groups a range of 100 to 700 trials was necessary to obtain a mean with a precision of 10%. These results suggest that... |

| To study the effect of age on the metrics of upper and lower eyelid saccades, eyelid movement of two groups of 30 subjects each were measured using computed image analysis. The patients were divided on the basis of age into a younger group (20-30 years) and an older group (60-91 years). Eyelid saccade functions were fitted by the damped harmonic oscillator model. Amplitude and peak velocity were used to compare the effect of age on the saccades of the upper and lower eyelid. There was no statistically significant difference in saccade amplitude between groups for the upper eyelid (mean ± SEM; upward, young = 9.18 ± 0.32 mm, older = 8.93 ± 0.31 mm, t = 0.56, P = 0.58; downward, young = 9.11 ± 0.27 mm, older = 8.86 ± 0.32 mm, t = 0.58, P = 0.56) However,... |

| The Yanomami are one of the last primitive groups of Indians living in Brazil. They have almost no contact with other cultures. The epidemiology of eye disease among Yanomami is virtually unknown. For the first time, a trachoma survey was conducted among Yanomami Indians in the State of Amazonas near the Venezuelan border of the Brazilian rain forest. Ophthalmic examination was carried out on a total of 613 individuals (338 males and 275 females) from eight Yanomami villages along the Marauiá River located in the upper Rio Negro Basin. Age was classified into three categories (children, adults, and elderly) and trachoma was classified into five grades: follicular, inflammatory intense, cicatricial, trichiasis, and corneal opacity. Trachoma was endemic in... |
