The BCVA examination with Snellen chart, intraocular pressure (IOP) measurement with Goldmann applanation tonometer, biomicroscopic anterior segment examination, and fundus examination were performed by the same ophthalmologist in each patient. Cases detected glaucoma in fundus examination and IOP measurements according to the European Glaucoma Society guidelines (10 ) were excluded from the study. The eyes of the participants were evaluated for (UEH; easily everted upper eyelids) and FES. It was considered as UEH if tarsal plate turn easily with gentle traction on the upper eyelid. If papillary conjunctivitis was accompanied by UEH, it was defined as FES (11 (link)). All ophthalmic examinations and measurements were done for each individual in the identical testing room under standard condition by same experienced person (II) in the same time zone (between 9 and 12 a.m) without pupil dilation. Participants were also compared with regard to systemic conditions such as systemic HT and body-mass index (BMI). Corneal topography and anterior segment measurements were obtained by the Scheimpflug method by Sirius Topography system (CSO SIRIUS 3D Rotating Scheimpflug Camera and Topography System V.3.2).
