Retinal Vascular Changes in a Case of Straatsma Syndrome.

A 34-year-old asymptomatic woman with a history of amblyopia in her right eye presented for a routine examination. Fundus examination revealed broad myelinated nerve fibers along with telangiectatic vessels. Wide-field fluorescein angiography revealed no evidence of ischemia or active retinal neovascularization.

Prognostic significance of mediastinal standardized uptake value on positron emission tomography/computed tomography in patients with left upper lobe non-small cell lung cancer: Is invasive staging of aortopulmonary window lymph nodes necessary?

Background: This study aims to investigate whether the invasive staging of aortopulmonary window lymph nodes could be omitted in the presence of a suspected isolated metastasis in the aortopulmonary window lymph node on positron emission tomography/computed tomography.

Methods: Between January 2010 and January 2016, a total of 67 patients (54 males, 13 females; mean age: 59.9±8.

Bilateral Fracture-Dislocation of the Shoulder After Defibrillation.

Background: There are multiple reported injuries associated with cardiopulmonary resuscitation, most of them caused by the force of compressions, like sternal and rib fractures, abdominal organ injuries like splenic rupture, liver lacerations, and injuries to the upper airway and skin. Injuries related to defibrillation and cardioversion are rare, mostly related to skin and muscle injuries on where the defibrillation paddles were placed.

Case Report: A 52-year-old man presented to the Emergency Department with crushing chest pain.

Comparison of anatomical and functional outcomes of different surgical techniques in myopic macular hole without retinal detachment.

Aim: To define the anatomic and functional outcomes of pars plana vitrectomy (PPV) with internal limiting membrane (ILM) peeling, inverted ILM flap and free ILM patch graft technique for the treatment of myopic macular hole (MH) without retinal detachment.

Methods: Sixty-four eyes of 64 patients who underwent PPV for myopic MH were included. Group 1 consists of patients underwent ILM peeling (=26), and Groups 2 and 3 consists of patient underwent free ILM patch graft (=20) and inverted ILM flap procedure (=18) respectively.

Bietti crystalline dystrophy complicated by choroidal neovascularization treated with a single dose of aflibercept.

Bietti crystalline dystrophy is a rare hereditary autosomal recessive disease that causes photoreceptor loss secondary to degeneration of retinal pigment epithelium due to intracellular retinal pigment epithelial crystalline deposits and abnormal lipid metabolism. We aimed to present a case of choroidal neovascular membrane secondary to Bietti crystalline dystrophy diagnosed with multimodal imaging and treated with an intravitreal injection of aflibercept. A single dose of aflibercept injection might be effective due to its higher affinity for vascular endothelial growth factor (VEGF) in comparison with other anti-VEGFs.

Human serum albumin depletion based on dye ligand affinity chromatography via magnetic microcryogels.

One of the primary purposes of proteomic studies is to analyze the proteins in the blood to be considered as biomarkers. Albumin, which constitutes the majority of total serum proteins, complicates the discovery of low-density proteins that are important for the diagnosis of diseases. Based on this, an alternative approach for albumin depletion was developed in this study by covalently attached Cibacron Blue 3GA (CB) to magnetic microcryogels.

Did primary spontaneous pneumomediastinum risk factor alter in the period of COVID-19 pandemia?

Objectives: In this study, we aimed to establish risk factors for primary spontaneous pneumomediastinum associated with Coronavirus disease 2019 (COVID-19) and reveal those which are significant.

Methods: The study included 62 patients with primary spontaneous pneumomediastinum who presented to our hospital between 11 March 2020, the date of the first-reported COVID-19 case in our country, and 3 January 2021. Of these, 14 patients (22.

Variability in Physiological Traits Reveals Boron Toxicity Tolerance in Aegilops Species.

Boron (B) is an important micronutrient required for the normal growth and development of plants. However, its excess in the soil causes severe damage to plant tissues, which affects the final yield. Wheat, one of the main staple crops, has been reported to be largely affected by B toxicity stress in arid and semi-arid regions of the world.

Determination of the retinal toxicity of intravitreal colistin in rabbit eyes.

Purpose: To determine the possible adverse effects and safe dose range of intravitreal colistin, an antibiotic, after its intravitreal application.

Methods: Twenty eyes of 20 adult male and female New Zealand white rabbits were selected. Various concentrations of colistin were prepared.

Injectable Cryogels in Biomedicine.

Cryogels are interconnected macroporous materials that are synthesized from a monomer solution at sub-zero temperatures. Cryogels, which are used in various applications in many research areas, are frequently used in biomedicine applications due to their excellent properties, such as biocompatibility, physical resistance and sensitivity. Cryogels can also be prepared in powder, column, bead, sphere, membrane, monolithic, and injectable forms.

Posterior Polar Central Choroidal Dystrophy: A Case Report.

A 52-year-old male presented with a 25-year history of decreasing vision. Best corrected visual acuity was 0.3 in his right and 0.

Green laser induced foveal cyst sustained in a recreational laser light show.

We report the case of a 9-year-old boy complained of visual loss in his right eye after watching green laser light show being hit by a ray of a laser at shopping center before five days ago. The laser had a maximum power rating of 30 mW (US Food and Drug Administration class IIIB). Best-corrected visual acuity in his right eye was 0.

The assessment of macular electrophysiology and macular morphology in patients with vitiligo.

Purpose: We aimed to analyze the electrophysiologic function and morphology of macula in vitiligo patients.

Methods: Seventeen patients with vitiligo and 11 healthy subjects were studied. All participants underwent multifocal electroretinography (mfERG) and spectral domain optical coherence tomography (SD-OCT) evaluations.

Changes in Anterior Chamber Depth after Combined Phacovitrectomy.

Objectives: To evaluate changes in anterior chamber depth (ACD) and postoperative refractive outcomes after combined phacovitrectomy.

Materials And Methods: This study included 10 eyes of 10 patients that underwent combined phacovitrectomy (study group) and 14 eyes of 14 patients that underwent phacoemulsification surgery (control group) at İstanbul Medipol University Ophthalmology Department. Preoperative and 3-month postoperative best corrected visual acuity (BCVA), ACD, change in ACD and refractive outcomes were compared between the two groups.
