Article Synopsis
- The study compares macular vessel density (VD) in patients with macula-off rhegmatogenous retinal detachment (RRD) who underwent vitrectomy using either gas or silicone oil (SO) tamponade.
- Fifty patients participated, and results showed that both groups had significant improvements in best-corrected visual acuity (BCVA) after surgery, but the gas tamponade group had better outcomes.
- The silicone oil group had lower VD in certain retinal layers, indicating possible toxic effects on macular perfusion, while gas tamponade appeared to preserve VD, suggesting a preference for gas tamponade in these cases.
Objective: The aim of this study is to investigate the effects of preoperative parameters such as retinal nerve fiber layer (RNFL) thickness, visual acuity (VA), visual field (VF), and tumour volume on postoperative outcomes in patients with pituitary adenoma.
Design: Retrospective study.
Participants: Two-hundred and seventy-six eyes from 142 patients were included.
Article Synopsis
- The study aimed to compare macular displacement (MD) rates in patients with macula-off retinal detachments who had surgery using either silicone oil or C3F8 gas tamponade and to analyze its relationship with visual distortion (metamorphopsia).
- A total of 53 patients were included, with 28 receiving C3F8 gas and 25 receiving silicone oil, and the results showed a significant difference in MD rates between the two groups.
- The findings indicated that while MD occurred in both groups, it did not consistently correlate with the presence of metamorphopsia, suggesting that not all patients with MD experience visual distortions post-surgery.
Purpose: To investigate microvascular changes in the macular and peripapillary area in prolactinoma patients by using optical coherence tomography angiography (OCTA).
Design: A retrospective study.
Methods: This study included 40 patients with treatment-naive prolactinoma and 42 healthy controls.
Purpose: The aim of the study was to investigate the corneal and anterior segment characteristics in pseudoexfoliation syndrome (PXS), depending on the severity of the disease.
Materials And Methods: This cross-sectional study was conducted at a tertiary care hospital, in the ophthalmology department, in Turkey. Pseudoexfoliation syndrome group was classified into three groups.
Purpose: This study aimed to assess and compare the retinal toxicity associated with silicone oil (SO) and perfluoropropane (C3F8) tamponade following vitreoretinal surgery for fresh rhegmatogenous retinal detachment (RRD), utilizing the office-based Diopsys NOVA system for evaluation.
Methods: Patients who underwent vitreoretinal surgery for fresh RRD and had SO (group 1) or C3F8 (group 2) tamponade were included in a prospective analysis. Flicker full field electroretinography (ffERG) and pattern electroretinography (PERG) tests were performed at 6 months postoperatively.
Objectives: It was aimed to to provide a comprehensive assessment of therapeutic and tectonic emergency keratoplasty procedures, along with a discussion on their indications, prognostic factors for functional success, and postoperative outcomes.
Methods: Patients who underwent therapeutic or tectonic Penetrating Keratoplasty (PKP) procedures between 2010 to 2021 in our hospital were retrospectively reviewed. Patient files were evaluated in terms of demographic characteristics, medical and ocular history, visual acuity, initial ocular findings, presence of glaucoma, causative microorganisms, details of surgical procedures, complications, graft transparency and globe integrity.
Purpose: By comparing the densitometry findings of patients with type 1 diabetes mellitus (T1DM) and the healthy group, we aimed to understand the possible changes that may occur in the cornea and lens in those with diabetes mellitus (DM).
Design: Prospective, cross-sectional study.
Methods: A total of 60 eyes of 60 patients with T1DM and 101 eyes of 101 healthy subjects were included in this study.
Purpose: To evaluate corneal densitometry (CD) of patients with arcus senilis (AS) and its association with the serum lipid markers.
Methods: This is a cross-sectional, case-control study. The AS diagnosis was made clinically.
Aim: To evaluate corneal and crystalline lens densitometry in patients with vernal keratoconjunctivitis (VKC).
Methods: This is a case-control study. Patients with VKC and age-gender-matched healthy controls underwent a complete ophthalmologic examination with corneal and crystalline lens densitometry measurements.
Purpose: To report the limbal allograft transplantation and penetrating keratoplasty (PK) results in limbal stem cell deficiency (LSCD)-developed eyes because of chemical or thermal injury.
Methods: Medical records of 18 eyes of 14 patients who had undergone keratolimbal allograft (KLAL) or living-related conjunctival limbal allograft (lr-CLAL) with or without PK and followed up at least 1 year postoperatively were evaluated retrospectively. The preoperative LSCD grade was noted in all patients.
Objective: To evaluate the effects of solifenacin, darifenacin, and propiverine on nasal-, subfoveal-, temporal choroidal thicknesses (NCT, SFCT, TCT), intraocular pressure (IOP) and pupil diameter (PD).
Materials And Methods: Patients with overactive bladder (OAB) diagnosed according to The International Continence Society were administered with solifenacin, darifenacin or propiverine on a daily basis between November 2017 and May 2018. NCT, SFCT, TCT, IOP, and PD of these patients were measured and compared as initial, fourth and twelfth weeks.
Aim: To report the real-life experience and clinical results of intravitreal ranibizumab injections to neovascular age-related macular degeneration (nAMD) in a single institution in Turkey.
Methods: A total of 101 eyes of 89 patients with nAMD treated with intravitreal ranibizumab injection, followed up for at least 24mo between 2009 and June 2014, which were evaluated retrospectively. A (PRN) treatment protocol was performed after the patients had received three, monthly loading injections.
Objectives: The aim of this study was to evaluate the clinical features, follow-up and treatment results of patients diagnosed with Coats' disease.
Materials And Methods: Medical records of 27 patients diagnosed with Coats' disease in our clinic were reviewed retrospectively. All patients underwent complete ophthalmological examination and fundus photography was taken.
Purpose: The purpose of this study is to investigate the effects of long-term clozapine usage on tear film stability and corneal topographic parameters.
Material And Methods: The study was conducted between March 2014 and November 2014. Thirty patients who were diagnosed of schizophrenia and have been under clozapine treatment for 2.
