“…Novak et al [17] found that when serial measurements were performed with videokeratography (mean corneal power), the greater consistency was achieved with no tears or with some specific artificial tears in normal patients. Measurements were done at 0.5, 1, 2, 3, 4, 5, 6, 8 and 10 minutes after artificial tear instillation.…”

“…However, all of these factors are usually temporary. [6][7][8] Lieberman and Grierson, 9 by using specific computer software that recreates the corneal surface, showed that the lids distort the corneal shape. In another study by Read et al, 10 significant associations were found between the best-fitting corneal spherocylinder, corneal astigmatism, and the eyelid morphology parameters in 100 healthy adults.…”

“…No espasmo hemifacial há contrações musculares involuntárias e periódicas em um dos lados da face, levando a modificação da expressão do paciente do lado afetado (2) . No grupo estudado houve uma maior prevalência de pacientes do sexo feminino e com uma idade média de 64 anos, concordando com outros autores que encontraram uma maior prevalência em mulheres e em uma faixa etária entre 60 e 80 anos (2,(6)(7)(8) . O uso de toxina botulínica para o tratamento das distonias faciais está se ampliando nos últimos anos.…”

“…Existem várias evidências de que a compressão das pálpebras influencia a biomecânica corneana. O calázio, por exemplo, em pálpebra superior produz um achatamento corneano reversível (5) ; o mesmo ocorre em pacientes portadores de peso de ouro em pálpebra superior (6) . Neste estudo, investigamos a ocorrência de alterações nos valores ceratométricos, "best fit sphere" (anterior e posterior) e índice de Roush em pacientes portadores de espasmo hemifacial, comparando a curvatura corneana do olho acometido com a do olho contralateral e a influência do tratamento com toxina botulínica.…”
