Abstract:
AIM: To investigate the influencing factors of punctate staining of corneal epithelium in patients wearing orthokeratology.METHOD: Data of 280 cases wearing orthokeratology were collected, including 185 cases in the group without corneal staining and 95 cases in the group with corneal staining. All patients were examined for general distant vision, intraocular pressure, slit lamp, fundus examination after mydriasis, comprehensive optometry, corneal topography, corneal thickness, corneal endothelium, axial length, Schirmer Ⅰtest(SⅠt)before wearing lenses, meibomian gland loss score before wearing lenses, eccentric distance, interleukin-2(IL-2)in tear, tumor necrosis factor-α(TNF-α)content analysis and so on. The influencing factors of corneal epithelium punctate staining were analyzed by univariate and multivariate Logistic regression.RESULTS: There were significant differences in preoperative diopter, preoperative meibomian gland deletion score, IL-2, TNF-α and lens sediment between the two groups(all P<0.05). Logistic regression analysis showed that diopter before wearing lenses was a protective factor for corneal epithelium punctate staining. Before wearing lenses, the loss of meibomian gland score, IL-2, TNF-α and lens deposits were the risk factors of corneal epithelium punctate staining. In the detection of corneal epithelium punctate staining, the comprehensive advantage of lens deposits was obvious, the specificity of lens deposits was higher, and the sensitivity of IL-2 was the highest. CONCLUSIONS: Before wearing lenses, diopter is the protective factor of corneal epithelium punctate staining, and the loss of meibomian gland score, IL-2, TNF-α and lens deposits are the risk factors of corneal epithelium punctate staining.
