Resumen
Objective: To determine the prevalence of ocular findings of the external
structures and anterior segment of the eye, detected by biomicroscopic
examination in schoolchildren in Natal (RN) - Brazil. Methods: After
previous random selection, 1,024 pupils from elementary and secondary
public and private schools in the city of Natal were evaluated from March
to June 2001. All were submitted to preestablished standard research
norms, consisting of identification, demographic information, ophthalmologic
biomicroscopic examination, with slit lamp, performed by ophthalmologists
from the “Onofre Lopes” University Hospital. Results: Alterations
of the conjunctival and palpebral conditions were the most prevalent
(10.4% and 6.2% respectively). Follicles (4.2%) and papillae (3.0%) were
the frequent conjunctival lesions, while blepharitis (3.5%) and meibomitis
(1.1%) were the most detected abnormalities in the eyelids. Upon examining
the cornea, iris, lens and anterior vitreous, the most encountered findings
were nubecula (0.5%), papillary membrane reliquiae (0.5%), posterior
capsula opacity (0.8%) and hyaloid arteria reliquiae (2.0%). Conclusion:
The most prevalent findings affecting the external structures of the eye
such as eyelids and conjunctiva, consisted of blepharitis followed by
follicular reaction of the conjunctiva. The most prevalent abnormalities
in the cornea, iris, lens and anterior vitreous were nubecula, papillary
membrane reliquiae, posterior capsular opacity and hyaloid arteria
reliquiae, in that order
