Evaluation of lamina cribrosa thickness in patients diagnosed with central retinal vein occlusion

Purpose To evaluate the thickness of lamina cribrosa (LC) in both eyes of patients with unilateral central retinal vein occlusion (CRVO) and to compare with eyes of age-matched healthy control subjects. Methods This prospective case-control study included a total of 38 patients with unilateral CRVO and 42 healthy control subjects. The LC thickness was measured at the center of the optic disc using an enhanced depth imaging with the spectral domain optical coherence tomography in both eyes of patients with unilateral CRVO and eyes of healthy control subjects. The LC thickness of CRVO patients was evaluated one month after dexamethasone intravitreal implant (Ozurdex) injection. Results The mean LC thickness in affected eyes of patients with CRVO was significantly thinner than that of the healthy eyes (204.4 +/- 8.8 and 228.0 +/- 7.1 mu m, p < 0.001, respectively). Also, the unaffected fellow eyes had significantly thinner LC compared with eyes of healthy subjects (205.3 +/- 9.3 and 228.0 +/- 7.1 mu m, p < 0.001, respectively). There was no statistically significant difference in the thickness of LC between the affected and unaffected fellow eyes (p = 0.669). Conclusions The LC thickness in both eyes of CRVO patients was thinner than that of the healthy eyes. This finding suggests that thin LC may contribute to the development of CRVO as an ocular risk factor in addition to systemic factors

The Impact of Reused Phaco Tip on Outcomes of Phacoemulsification Surgery

Purpose: To evaluate the impact of reused phaco tip on intraoperative performance and postoperative outcomes after 2.2mm micro-coaxial torsional and transversal phacoemulsification

The Assessment of Anterior and Posterior Ocular Structures in Hyperopic Anisometropic Amblyopia

Background: The aim of this study was to examine the relationship or differences in ocular structures of amblyopic eyes compared to fellow eyes in children and young adults with hyperopic anisometropic amblyopia

Effects of moxifloxacin exposure on the conjunctival flora and antibiotic resistance profile following repeated intravitreal injections

AIM: To evaluate the effects of moxifloxacin exposure on the conjunctival flora and antibiotic resistance profile following repeated intravitreal injections

Comparison of corneal endothelial changes following phacoemulsification with transversal and torsional phacoemulsification machines

AIM: To compare and evaluate the phacoemulsification parameters and postoperative endothelial cell changes of two different phacoemulsification machines, each with different modes, but also to assess the relationship between postoperative endothelial cell loss and the phacoemulsification parameters, as well as the other factors in both groups

Retinal nerve fiber layer and macular thickness measurement in patients with schizophrenia

Purpose: To investigate the retina and macular thickness in patients with schizophrenia and to compare the results with those of healthy controls

The Effect of Pseudoexfoliation Syndrome on the Retinal Nerve Fiber Layer and Choroid Thickness

Purpose: To investigate thickness of the retinal nerve fiber layer (RNFL) and choroid thickness in patients with pseudoexfoliation syndrome (PEX) and pseudoexfoliation glaucoma (PXG) compared to healthy volunteers. Methods: This cross-sectional, prospective study included 43 patients with PXG, 45 patients with PEX syndrome, and 48 healthy volunteers. The RNFL and macular thickness were analyzed with standard OCT protocol while choroidal thickness was analyzed with EDI protocol in all subjects. Results: The RNFL thickness was higher in the PEX and control groups compared to the PXG group (p<0.001). The choroid thickness was significantly higher in the control group compared to the PXG and PEX groups (p<0.05). No significant difference was detected between the both groups. Conclusions: PEX might weaken choroid circulation by accumulating in choroid vessels. The thinner choroid in the PXG group suggests that ischemia affects the duration of PEX and has a role in the development of glaucoma

SINGLE-CENTERED QUESTIONNAIRE STUDY: PROFESSIONAL ASSESSMENT AMONGST ANESTHESIOLOGY RESIDENTS

Objective: Anesthesiology is a special branch which requires different practice places, necessity for collaboration with various teams and frequently taking fast and right decisions. In this respect, stress is frequently experienced. It has been reported that unmanaged stress has become a worldwide concern for the anesthesiologists. In this study, we aimed to investigate the reasons for anesthesiology residents' professional satisfaction and stress during their training period and we have tried to identify the qualifications which a good anesthesiologist should have

Systemic Endothelial Function in Primary Open-Angle Glaucoma

Objective. We aimed to assess peripheral vascular endothelial function in open-angle glaucoma (POAG) by measuring flow-mediated dilatation (FMD). Materials and Methods. The study included 20 cases with POAG (group 1, mean age 58.68±13.3 years) and 30 healthy individuals (group 2, mean age 58.68±13.6 years). In all cases, responses of endothelial function were assessed by a cardiologist through measurement of FMD following brachial artery occlusion. Results. Mean percent of FMD, an indicator of endothelial function, was found to be 11.9±4.2% in group 1 and 12.3±4.4% in group 2 (P=0.86). Conclusion. No impairment in systemic vascular function of cases with POAG suggests that POAG could be a local disorder rather than being a component of systemic disease
