ABSTRACT
PURPOSE: This study aimed to investigate the effect of upper eyelid blepharoplasty with the removal of the skin and a strip of orbicularis oculi muscle on the ocular surface, tear film, and dry eye-related symptoms. METHODS: Twenty-two eyes of 22 consecutive patients operated by a single surgeon (21 females; mean age, 61 years; age range, 41-75 years) were included. All subjects completed the Ocular Surface Disease Index questionnaire, underwent in vivo confocal microscopy, tear film breakup time measurements, the Schirmer test with anesthesia, and fluorescein and lissamine green staining measurements before, 1 month, and 6 months after upper blepharoplasty alone with preseptal orbicularis excision. RESULTS: A significant increase in Ocular Surface Disease Index, and corneal fluorescein and lissamine green staining and a significant decrease in tear film breakup time were observed after 1 month (p=0.003, p=0.004, p=0.029, and p=0.024 respectively) and 6 months (p=0.001 for all findings). No significant difference in the Schirmer test score was observed during the follow-up. None of the in vivo confocal microscopy parameters showed significant changes during the study. CONCLUSIONS: An increase in dry eye symptoms and a decrease in tear film stability along with ocular surface staining were observed in patients undergoing upper eyelid blepharoplasty.

ABSTRACT
PURPOSE: We sought to investigate alterations in the corneal subbasal nerve plexus and endothelium in patients with Behçet's disease (BD). METHODS: This cross-sectional study included 64 patients with BD and 30 age- and gender-matched healthy control subjects. Those with BD were classified as having ocular or non-ocular disease. All subjects underwent a corneal endothelial and subbasal nerve density evaluation using in vivo confocal microscopy (IVCM). The differences among groups were analyzed using the Kruskal-Wallis test followed by Dunn's multiple comparison procedure. RESULTS: The mean age of study participants was 35.7 ± 10.2 years (16-58) in the ocular BD group, 39.6 ± 14.9 years (11-66) in the non-ocular BD group, and 34.1 ± 11.2 years (21-55) in the control group. No statistical significance was found in terms of age (p = 0.259) or sex (p = 0.560) between groups. The mean endothelial cell density determined with IVCM was 2124.9 [Formula: see text] 417.4 cells/mm2 (1811-3275) in the ocular group and 2546 [Formula: see text] 335 cells/mm2 (1798-3280) in the control group (p = 0.000). In the ocular group, the mean density of the subbasal nerve plexus was significantly lower (p = 0.004), and nerve tortuosity was significantly higher (p = 0.002). CONCLUSIONS: Ocular BD could be responsible for changes in the corneal layers, especially endothelial and corneal nerve structures. Nerve density and tortuosity differences could be inflammatory indicators for BD.

PRCIS: This cross-sectional study of 20 patients with primary open-angle glaucoma (POAG), 20 with exfoliative glaucoma (XFG), 20 with exfoliation syndrome (XS) showed that exfoliative group had a significantly lower smell identification level as compared with the control groups. PURPOSE: To investigate smell sensitivity in POAG, XFG, and XFS in comparison with healthy controls. MATERIALS AND METHODS: This prospective, cross-sectional study included 20 patients with POAG, 20 with XFG, and 20 with XFS. The control group consisted of 20 age-matched and sex-matched healthy subjects with no evidence of ocular disease. The Sniffin' Sticks smell test was used to determine the, threshold values, and to assess the ability of smell identification, and differentiation in all patients One eye per patient was included for statistical purposes. One-way analysis of variance was used to compare the differences between the groups. Tukey honestly significant difference was used as a post hoc test when significant differences were detected among the 3 groups. RESULTS: The XFG, POAG, and control groups showed a significant difference in the odor discrimination, odor identification, and threshold discrimination identification scores. The median (minimum-maximum) smell threshold levels for the POAG, XFG, and XFS groups and healthy controls were 4.5 (0 to 7.5), 4 (0 to 7.5), 5 (4.5 to 6), and 5.5 (4 to 7.5), respectively. The smell differentiation values for the POAG, XFG, and XFS groups and healthy controls were 12 (2 to 14), 8 (0 to 13), 11 (10 to 13), and 12 (9 to 14), respectively. Smell sensitivity for the POAG, XFG, and XFS groups and healthy controls were 26 (4 to 30.5), 19 (0 to 29.5), 28.3 (22.8 to 30.5), and 29 (26.5 to 32), respectively. The smell sensitivity and differentiation were significantly different among the groups (P<0.001). The XFG group had a significantly lower smell identification level than the POAG, XFS, and control groups. CONCLUSION: Patients with XFS and XFG revealed reduced smell sensitivity and identification compared with patients with POAG and those without glaucoma. These findings provide new insights into neural degeneration and pseudoexfoliation.
