    Aim: In this study, we aim to perform Cost Minimization Analysis of cefuroxime and moxifloxacin, which have proven to have a similar efficacy in the prophylaxis of endophthalmitis after cataract surgery.Material and Methods: The records of 1097 patients who had undergone cataract surgery and intracameral antibiotic (cefuroxime, moxifloxacin) injection in 2018 were evaluated retrospectively. Patients undergoing cataract surgery were divided into two groups according to the type of antibiotic injected into the anterior chamber. Group 1 consisted of patients who received intracameral 1mg/0.1ml cefuroxime and Group 2 consisted of patients who received intracameral 500 µg /0.1ml moxifloxacin. In the postoperative period, patients in both groups received topical antibiotic drops containing 0.5% moxifloxacin and steroid drops containing 0.1% dexamethasone for 7 days. Results: The Group 1 consisted of 213 (19.4%) patients, of which 97 (45.5%) were male and 116 (54.5%) were female, while Group 2 consisted of 884 (80.6) patients, of which 439 (49.7%) were male, and 445 (50.3%) were female (p=0.280). The groups were similar in terms of age and gender distribution of the patients. There was no significant difference in terms of the posterior capsule rupture development between the two groups (p=0.692).BCVA was statistically significant before and after surgery in both groups. None of the patients in both groups developed endophthalmitis. The cost of the drugs used in the first group was 3 times higher than the second group.Conclusion: The antibiotics injected to the anterior chamber during cataract surgery have similar effectiveness, moxifloxacin injection to the anterior chamber was found to be more advantageous in terms of cost, compared to the use of disposable cefuroxime.Keywords: Cataract surgery; intracameral antibiotic; cost.

    Thiol/Disulfide Homeostasis in Patients with Central Serous Chorioretinopathy

    Purpose: To evaluate dynamic thiol/disulfide homeostasis in patients with chronic central serous chorioretinopathy (cCSC).Methods: This prospective study included 34 cCSC cases and 37 healthy individuals who were age- and sex-matched. A new colorimetric method for measuring thiol/disulfide homeostasis was used. Native thiol, total thiol/disulfide levels, disulfide/native thiol, disulfide/total thiol, and native thiol/total thiol ratios were measured.Results: The age and gender distributions were similar in both main groups. The mean duration of disease was 47.29 24 months. Native and total thiol levels were significantly lower among the cCSC group relative to the control group (p < 0.001). There was not a statistically significant difference between the cCSC and the control group in terms of disulfide levels (p = 0.492). While disulfide/native thiol and disulfide/total thiol ratios were elevated, the native thiol/total thiol ratio was decreased in the cCSC group (p = 0.017, 0.021, 0.036, respectively). Ratios obtained using plasma native thiol, total thiol, and disulfide levels differed significantly between the both groups.Conclusion: Disulfide/thiol ratio was significantly greater in cCSC patients relative to healthy control subjects. Our results suggest that the oxidative process is involved in the pathogenesis of the cCSC.
