Resumo
OBJETIVO: Avaliar quantitativamente as mudanças da posição palpebral e as medidas da fenda palpebral de indivíduos acima dos 50 anos. MÉTODOS: Estudo observacional, tendo sido avaliados 325 indivíduos, com idade acima de 50 anos, segundo distância intercantal, largura e altura da fenda palpebral, ângulo palpebral externo e interno, distância entre o reflexo pupilar e a margem da pálpebra superior (distância reflexo-margem) e a área total da fenda palpebral. Utilizou-se filmadora Sony Lithium para obtenção das imagens digitais, com o indivíduo fixando um objeto a 1 metro de distância, sendo as imagens transferidas posteriormente para computador McIntosh G4 e processadas pelo programa NIH 1.58. Os dados foram submetidos à análise estatística. RESULTADOS: Os participantes apresentavam dermatocálase (96,5%), ptose do supercílio (60,8%), prolapso de gordura orbital (50,0%) ou ptose palpebral (39,1%). As alterações foram bilaterais em 68,8% dos indivíduos. A distância intercantal aumentou com a idade; a largura da fenda palpebral, a distância reflexo-margem e a medida do ângulo externo diminuíram nos mais idosos. As diferenças foram mais significativas quando os olhos foram estudados separadamente. CONCLUSÃO: A distância intercantal aumenta, ao passo que a largura da fenda palpebral, a distância reflexo-margem e a área total da fenda palpebral diminuem com o aumento da idade.
PURPOSE: To quantify the palpebral alterations occurring in subjects after the age of 50 years. METHODS: An observational study was done with 325 subjects older than 50 years. The data comprised measurements of intercantal distance, palpebral fissure length and height, external and internal eyelid angles, margin reflex distance (MRD) and total palpebral fissure area. Digital images were obtained with a Sony Lithium movie camera at the frontal view in ocular primary position, with the object of observation being located at the height of the pupil. The images were saved on tape, transferred to a McIntosh G4 computer and processed with the NIH 1.58 program. The data were submitted to statistical analysis. RESULTS: The subjects presented dermochalasis (96.5%), eyebrow ptosis (60.8%), orbital fat prolapse (50.0%) or eyelid ptosis (39.1%). The alterations were bilateral in 68.8% of the subjects. The intercantal distance was higher with age; the eyelid fissure length, the margin reflex distance and the external angle decreased in the elderly. The differences were more important on evaluating each eye separately. CONCLUSION: Intercantal distance increase and palpebral fissure length, margin reflex distance and total eyelid area decrease with age.
