ABSTRACT

ABSTRACT Purpose: We aimed to compare the thickness of anterior sclera, corneal layers, and pre-ocular tear film between patients with primary Sjögren's syndrome and healthy individuals. Methods: Fifty-one patients with primary Sjögren's syndrome and 41 healthy control participants were recruited in this cross-sectional and comparative study. The thickness of the pre-ocular tear film, corneal epithelium, Bowman's layer, stroma, Descemet's membrane, and endothelium were measured on the corneal apex. Anterior scleral thickness was measured at distances of 1 mm and 3 mm from the limbus. The anterior segment module of spectral-domain optical coherence tomography was used to measure thicknesses of pre-ocular tear film, corneal layers, and anterior sclera. Results: Tear film thickness, Schirmer's test, and tear break up time values were significantly lower in the Sjögren's disease group than in the healthy controls (p<0.05). The thickness measurements of corneal layers and sclera were similar between the groups. Tear film thickness was moderately correlated with the Schirmer's test results (r=0.34, p=0.001), but there was no correlation between the Schirmer's test results and tear break up time (r=0.18, p=0.09). Conclusions: Pre-ocular tear film, as measured by anterior segment optical coherence tomography, was thinner in patients with primary Sjögren's syndrome than in the healthy controls. The thicknesses of corneal layers and anterior sclera were similar between the groups.


RESUMO Propósito: Nosso objetivo foi comparar a espessura da esclera anterior, camadas da córnea e do filme lacrimal pré-ocular entre pacientes com síndrome de Sjögren primária e indivíduos saudáveis. Métodos: Cinquenta e um pacientes com síndrome de Sjögren primária e 41 controles saudáveis foram recrutados neste estudo comparativo e transversal. A espessura do filme lacrimal pré-ocular, epitélio corneal, camada de Bowman, estroma, membrana de Descemet e endotélio foram medidos no ápice corneal. A espessura da esclera anterior foi medida às distâncias de 1 mm e 3 mm do limbo. O módulo do segmento anterior da tomografia de coerência óptica de domínio espectral foi utilizado para mensurar as espessuras do filme lacrimal pré-ocular, camadas da córnea e esclera anterior. Resultados: A espessura do filme lacrimal, o teste de Schirmer e os valores do tempo de ruptura do filme lacrimal foram significativamente menores no grupo com síndrome de Sjögren do que nos controles saudáveis (p<0,05). As medidas de espessura das camadas corneais e da esclera foram similares entre os grupos. A espessura do filme lacrimal foi moderadamente correlacionada com os resultados do teste de Schirmer (r=0,34, p=0,001), mas não houve correlação entre os resultados do teste de Schirmer e tempo de ruptura (r=0,18, p=0,09). Conclusões: O filme lacrimal pré-ocular, medido pela tomografia de coerência óptica de segmento anterior, foi mais fino em pacientes com síndrome de Sjögren primária do que nos controles saudáveis. As espessuras das camadas da córnea e da esclera anterior foram semelhantes entre os grupos.
