    Comparison of the results between monocanalicular and bicanalicular silicone tube intubation in children with congenital nasolacrimal duct obstruction
    (2021) Demirel, Soner; Demir, Ulku
    Aim: In this study we aimed to compare the retrospective results of the success rates in children with congenital nasolacrimal duct obstruction undergoing monocanalicular and bicanalicular silicone tube intubation. Materials and Methods: Bicanalicular (Group 1) and monocanalicular (Group 2) silicone tube intubation was performed in 48 eyes of 42 patients using the Ritleng method. Sixteen of the patients were boys and 26 were girls. Bicanalicular silicone tube intubation was performed in 26 eyes of 22 patients, and monocanalicular silicone tube intubation was performed in 22 eyes of 20 patients. Results: The mean age of patients was 5.68±1.83 years (2-9 years) in the first group, and 5.05±1.76 years (3-9 years) in the second group. The period of leaving the silicone tube was 3.61±1.38 months (1-6 months) in the first group, and 3.18±1.00 months (1-6 months) in the second group. The mean follow up period of the patients was found to be 11.8 months (6-36 months) in the bicanalicular group and 14.0 months (6-36 months) in the monocanalicular group.The success rate was 92.30% (22 of 26 eyes) in the first group and 95.45% (21 of 22 eyes) in the second group. In the first group, 2 patient’s bicanalicular tube was removed spontaneously 2 months ago, 2 patients were performed dacryocystorhinostomy, 1 patient developed pyogenic granuloma and laceration occurred in the lower canaliculus of 1 patient. In the second group, the tubes of 2 patients were removed spontaneously 2 months ago and silicone tube intubation was performed again with the same method. In this group, 1 patient was then performed dacryocystorhinostomy and 1 patient developed conjunctivitis. There were no corneal or conjunctival complications in either group. Conclusion: There was no statistically significant difference in success rates between the groups (p>0.05)

    The relation of neutrophil/lymphocyte ratio, platelet/lymphocyte ratio and mean platelet volume with idiopathic acute anterior uveitis
    (Sage Publications Inc, 2024) Demir, Ulku
    Objective: In this study leukocyte, lymphocyte, neutrophil, platelet count, mean platelet volume (MPV), neutrophil/lymphocyte (NLR) ratio and platelet/lymphocyte ratio (PLR) were retrospectively evaluated in patients with idiopathic acute anterior uveitis. Materials and methods: Medical records were retrospectively reviewed from March 2016 to February 2020. Fifty patients (25 men and 25 women) and as the control group, 50 healthy volunteers (25 males and 25 females) were included in this study. Blood samples of the patients were taken before starting treatment. A complete ophthalmological examination, including corrected visual acuity, tonometry, slit lamp and fundus examination, was performed in all patients. Gender, age, leukocyte, neutrophil, lymphocyte, platelet, MPV, PLR, and NLR values of the patients were recorded. Results: In this study, a statistically significant difference was found in leukocyte (p < .001), neutrophil (p < .001), platelet (p < .001), NLR (p < .001) and PLR (p < .001) values. No significant difference was found between the two groups in terms of lymphocyte count (p = .063) and in the MPV value (p = .051). Leukocyte, neutrophil, platelet count, NLR, and PLR values were higher in the uveitis group compared to the control group. In the receiver operating characteristic (ROC) curve analysis, the area under the curve (AUC) for NLR was 0.805, with a sensitivity of 56.0% and a specificity of 98.0%. The AUC for PLR was 0.657, with a sensitivity of 52.0% and a specificity of 98.0%. Conclusion: In this retrospective study, leukocyte, neutrophil, platelet count, PLR, and NLR levels were significantly higher in patients with idiopathic acute anterior uveitis compared to the control group. These blood parameters are useful as diagnostic markers and can be used in early diagnosis.
