Peribulbar vs. incisionless sub-Tenon's blocks: a retrospective cohort study.

Background: Ophthalmic procedures are increasingly being performed under regional anesthesia techniques such as peribulbar and incisionless sub-Tenon's blocks. The aim is to compare peribulbar block with incisionless sub-Tenon's block in terms of perioperative complications in patients who underwent cataract and vitreoretinal surgeries.

Methods: The patients who underwent cataract or vitroretinal surgery under peribulbar block or incisionless sub-Tenon's block were included in the study.

The relationship of retinopathy of prematurity with brain-derivated neurotrophic factor, vascular endotelial growth factor-A, endothelial PAD domain protein 1 and nitric oxide synthase 3 gene polymorphisms.

Background: In addition to risk factors such as low birth weight and uncontrolled oxygen therapy, genetic predisposition is also thought to play a role in the development of retinopathy of prematurity (ROP). In our study, we aimed to analyze single-nucleotide polymorphisms (SNPs) in and genes in infants who develop ROP.

Materials And Methods: Seventy-five mild-moderate and 73 severe ROP cases were included in this study.

Evaluation of the Vestibulocochlear System in Patients with Pseudoexfoliation Syndrome.

Objectives: Patients with pseudoexfoliation syndrome (PES) can also have sensorineural hearing loss as well as balance problems. Our aim was to evaluate vestibulocochlear system involvement in PES patients.

Materials And Methods: The study included 16 subjects with PES (study group) with a mean age of 66.

The Relationship Between Vasoproliferative Tumor and Uveitis in a Multiple Sclerosis Patient: A Case Report and Review of the Literature.

Vasoproliferative retinal tumor (VPRT) is a rare, benign lesion with a variable clinical course depending on the individual. Favorable outcomes are obtained with early diagnosis and treatment of patients with VPRT. In this case report, we present a case of concomitant VPRT and multiple sclerosis along with our management of uveitis and secondary glaucoma that presumably developed following cryotherapy for VPRT.

The influence of corneal geometrical and biomechanical properties on tonometry readings in keratoconic eyes.

Purpose: To identify the effect of corneal geometrical and biomechanical parameters on the intraocular pressure (IOP) measurements obtained by Goldmann Applanation Tonometer (GAT), non-contact tonometer, iCare Pro Rebound Tonometer (IRT), Tonopen and Ocular Response Analyzer (ORA, Goldmann-correlated IOP: IOPg, corneal compensated IOP: IOPcc).

Methods: We prospectively recruited patients with a tomographically confirmed diagnosis of keratoconus. IOP measurements were performed in the following order: non-contact tonometry, ORA, IRT, GAT and Tonopen.

Coexistence of Peripheral Retinal Diseases with Macular Hole.

Objectives: To investigate the frequency of retinal tear, retinal hole, and lattice degeneration in peripheral retinal examination of patients with macular hole.

Materials And Methods: The files of patients who underwent pars plana vitrectomy surgery with a diagnosis of macular hole at Eskişehir Osmangazi University Department of Ophthalmology between 2008 and 2018 were retrospectively analyzed. A total of 106 patients with primary macular hole who underwent peripheral retinal examination were included in the study.

Corneal elevation changes after forced eyelid closure in healthy participants and in patients with keratoconus.

Background: To assess pointwise corneal elevation changes after forced eyelid closure test (FECT) in the eyes of healthy subjects and in eyes with keratoconus.

Methods: Twenty-nine subjects with keratoconus and 31 healthy volunteers were evaluated. Patients with keratoconus who had corneal hydrops, apical scarring, corneal thickness ≤ 400 μm, ocular surface disease, contact lens wear on the examination day and a history of corneal cross-linking were excluded.

Ahmed glaucoma valve implantation versus suprachoroidal silicone tube implantation following the injection of bevacizumab into the anterior chamber in patients with neovascular glaucoma.

Purpose: This study compared the efficacy and safety of Ahmed glaucoma valve (AGV) implantation versus suprachoroidal silicone tube (SST) implantation after the injection of bevacizumab into the anterior chamber in patients with neovascular glaucoma.

Methods: Patients were randomly assigned to undergo AGV or SST implantation. Bevacizumab was injected into the anterior chamber at a dosage of 1.

The analysis of posterior segment findings in term and premature infants using RetCam images.

Objective: To analyze posterior segment findings in term and premature infants using the RetCam image database.

Methods: RetCam images taken of infants born between January 2012 and December 2015 were reviewed. Group 1 included infants with posterior segment findings other than retinopathy of prematurity (ROP).

Vasoactive intestinal peptide, a promising agent for myopia?

Aim: To investigate the role of vasoactive intestinal peptide (VIP) in form-deprivation myopia (FDM).

Methods: FDM was created in three groups of eight chicks by placing a translucent diffuser on their right eyes. Intravitreal injections of saline and VIP were applied once a day into the occluded eyes of groups 2 and 3, respectively.

A Possible Regression Equation for Predicting Visual Outcomes after Surgical Repair of Open Globe Injuries.

. To analyze the effects of factors other than the ocular trauma score parameters on visual outcomes in open globe injuries. .

Comparison of Different Types of Complications in the Phacoemulsification Surgery Learning Curve According to Number of Operations Performed.

Objectives: To compare the differences in intraoperative complications rates by the number of resident-performed sequential phacoemulsification surgeries.

Materials And Methods: Preoperative and postoperative ophthalmological examination records and intraoperative data of 180 eyes of 140 patients who underwent cataract surgery by two residents between November 2009 and February 2012 were analyzed retrospectively. The data of 180 eyes were separated into 3 groups based on the number of operations performed: Group A (first 1-60 eyes), group B (61-120 eyes) and group C (last 121-180 eyes).

The macular findings on spectral-domain optical coherence tomography in premature infants with or without retinopathy of prematurity.

The purpose of the study was to present spectral-domain optical coherence tomography (OCT) findings in premature infants with or without mild-to-severe retinopathy of prematurity (ROP). Seventy-two infants born <37 weeks of gestation were analyzed, prospectively. Group 1 (n = 18) included infants without ROP.

Bilateral Coats' Disease Combined with Retinopathy of Prematurity.

Purpose. To report a case of bilateral Coats' disease combined with retinopathy of prematurity (ROP). Case.

A rare association of intravitreal bevacizumab injection with double ridge formation in retinopathy of prematurity.

A second anterior ridge formed 8 weeks after therapy in a case of zone II, stage 3 retinopathy of prematurity, which was treated with intravitreal bevacizumab injection alone. The clinical appearance was defined as "double ridge." Retinopathy of prematurity cases treated only with intravitreal bevacizumab injections may progress; therefore, close follow-up is recommended.

Quadrantwise Comparison of Lens-Iris Distance in Patients With Pseudoexfoliation Syndrome and Age-matched Controls.
