This study examines the association between excessive digital media use and adverse health outcomes, specifically Digital Eye Strain (DES) and Poor Sleep Quality (PSQ), in adolescents. A cross-sectional survey of 512 participants (aged 11-18 years) assessed DES and PSQ using the Computer Vision Syndrome Questionnaire and the Pittsburgh Sleep Quality Index. We found a high prevalence of DES (63.

Background Congenital fibrosis of the extraocular muscles (CFEOM) is a non-progressive sporadic or familial disease characterized by abnormal innervation of the extraocular muscles. This study aims to evaluate the types of diseases, management steps, and surgical outcomes. Methodology A total of 76 patients diagnosed with CFEOM between 2000 and 2022 were evaluated retrospectively.

Background: To compare the changes in anterior chamber laser flare after phacoemulsification and intraocular lens implantation according to phaco parameters in eyes with and without pseudoexfoliation syndrome.

Methods: Patients (39 without pseudoexfoliation (PEX), 28 with pseudoexfoliation) who underwent the surgery with the same device (Centurion System, Alcon Laboratories, USA) and same experienced surgeon were divided according to the presence of PEX. Anterior chamber laser flare was assessed using a laser flare meter (Kowa-FM700, Kowa Company, Japan) by the same blinded researcher.

Objectives: The purpose of this study was to assess the stabilization of anatomical outcomes of central corneal thickness (CCT), anterior chamber depth (ACD), and iridocorneal angle (ICA) in keratoconus-affected eyes after deep anterior lamellar keratoplasty (DALK).

Methods: Keratoconus patients who underwent DALK surgery at Beyoğlu Eye Training and Research Hospital between January 2013 and May 2015 were retrospectively analyzed. Patients with data recorded preoperatively, 1 month postoperatively, and 1, 6, and 12 months post suture removal, including refractive status, best corrected visual acuity (BCVA), CCT, ACD, and ICA parameters were included in the study.

Purpose: To investigate the effect of the clival bone pattern on the abducens nerve (AN) localization in the petroclival region between the Pediatric and Adult Groups.

Methods: This study used 12 pediatric and 17 adult heads obtained from the autopsy. The length and width of the clivus and the length of the petrosphenoidal ligaments (PSLs) were measured.

Objectives: The aim of this retrospective study was to evaluate the efficacy of the intravitreal injection of anti-vascular endothelial growth factor (anti-VEGF) agents to treat choroidal neovascularization (CNV) caused by a pathology other than exudative type age-related macular degeneration (AMD).

Methods: This was a retrospective study of 43 treatment naive eyes of 35 patients who had been diagnosed with CNV caused by a pathology other than exudative- type AMD and who underwent intravitreal injection of anti-VEGF agents. Primary and secondary outcome measures were the best corrected visual acuity (BCVA) and the central macular thickness (CMT).

Objectives: The aim of this study was to establish prognostic and predictive markers in patients with subarachnoid hemorrhage (SAH) using simple laboratory methods.

Methods: A retrospective examination was made of patients with SAH diagnosed secondary to isolated head trauma, isolated anterior communicating artery aneurysm rupture, and angiography-negative SAH. Age, gender, Glasgow Coma Scale (GCS) scores, and Fisher's grade scores, Glasgow Outcome Scale (GOS) scores, leukocyte count, neutrophil count, lymphocyte count, platelet count, neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio results (PLR) were evaluated.

Despite advances in spinal biomechanic research, surgical techniques, and rehabilitation processes, no significant improvement has been identified in the treatment of spinal cord injury (SCI) and neurological recovery. This study was designed to investigate the potential therapeutic effects of methylprednisolone and levetiracetam on SCI. In this study, 42 male Wistar Albino rats, each weighing 300-350 g, were separated into three main groups: control group, acute and subacute stage groups.

Objective: The aim of this study was to compare strain elastography (SE) and shear wave elastography (SWE) findings of the sciatic nerve in patients with unilateral lumbar disc herniation (LDH) and healthy control subjects.

Materials And Methods: The study group included patients with complaints of unilateral sciatica for 3-12 months, with foraminal stenosis due to one level of LDH (L4-L5 or L5-S1). An age- and gender-matched control group was formed of healthy subjects.

In the present study, we investigated the types and ratio of posterior clinoid process (PCP) pneumatization in paranasal sinus multidetector computed tomography (MDCT). Paranasal MDCT images of 541 subjects (227 males, 314 females), between 15 and 65 years old, were included into the study. Pneumatization of anterior clinoid process and pneumatization types (I, II, or III) were evaluated in the males and females.

Vacuum disc phenomenon is seen frequently with degenerative disc disease and is characterized by the collection of gas in the disc space. Although the accumulation of gas within the disc space does not have clinical significance, symptoms may develop when occurring within the spinal canal. We present a 60-year-old female patient with low back and left leg pain occurring for 3 months before admission to our clinic.

Under pathological conditions such as brain trauma, subarachnoid hemorrhage and stroke, cortical spreading depression (CSD) or peri-infarct depolarizations contribute to brain damage in animal models of neurological disorders as well as in human neurological diseases. CSD causes transient megachannel opening on the neuronal membrane, which may compromise neuronal survival under pathological conditions. Poloxamer-188 (P-188) and citicoline are neuroprotectants with membrane sealing properties.
