Trata-se da incapacidade de fechar as pálpebras completamente. Piscar cobre o olho com uma fina camada de fluido lacrimal, promovendo assim um ambiente úmido necessário para as células da parte externa do olho. As lágrimas também eliminam corpos estranhos e os carregam para fora do olho. Isso é crucial para manter a lubrificação e a saúde ocular adequada. Se esse processo estiver prejudicado, como no lagoftalmo, o olho pode sofrer abrasões e infecções. O lagoftalmo leva a ressecamento e ulceração da córnea. Esse diagnóstico é quando envolve a pálpebra superior. | |||

This is the mechanical inability to close the eyelids completely. Blinking covers the eye with a thin layer of tear fluid, thereby promoting a moist environment necessary for the cells of the exterior part of the eye. The tears also flush out foreign bodies and wash them away. This is crucial to maintain lubrication and proper eye health. If this process is impaired, as in lagophthalmos, the eye can suffer abrasions and infections. Lagophthalmos leads to corneal drying and ulceration. This diagnosis is of the upper eyelid. | |||
