The effect of three different mydriatic eye drops on retinal vessel diameters.

Purpose: To investigate the effects of topically applied 1% tropicamide, 2.5% phenylephrine and 1% cyclopentolate on retinal vessel calliper (VC) using optical coherence tomography (OCT).

Methods: Patients who came to the ophthalmology clinic for routine examination and whose OCT films were taken before dilatation and after 30 min of last dilatation drop were included in the study.

Macular Pigment Optical Density in First Degree Relatives of Age-Related Macular Degeneration Patients.

Purpose: To measure the macular pigment optical density in first-degree relatives of patients with age-related macular degeneration and compare it with a healthy control group.

Methods: One hundred and twenty-eight healthy subjects who were first-degree relatives of age-related macular degeneration patients were included in the study (Group 1). As the control group, 74 healthy subjects were included in the study (Group 2).

The effects of hyperbaric oxygen therapy on retinal layers in healthy eyes.

Purpose: The aim of our study is to investigate the effects of hyperbaric oxygen (HBO2) therapy on retinal layers in healthy eyes.

Method: Thirty patients who were taken to outpatient HBO2 for any indication were included in the study. All patients underwent 10 sessions of HBO2; 20 healthy patients were taken as the control group.

Evaluation of neonatal hearing screening results of newborns with premature retinopathy.

Objectives: To reveal the risk situations of ROP patients in terms of hearing loss by examining the newborn hearing screening test results.

Methods: Hearing screening test results of ROP patients and newborns with similar congenital risk factors(control group) treated in our hospital were retrospectively screened. Both groups were compared in terms of newborn hearing screening test results.

Reliability of YouTube Videos in Vitreoretinal Surgery.

Background And Objective: To investigate the reliability and quality of vitreoretinal surgery videos posted on YouTube.

Patients And Methods: A search was made using the keywords "vitrectomy," "retinal surgery," and "vitreoretinal surgery" on YouTube. Total view counts, numbers of comments, likes and dislikes, publishing dates, and source of videos were recorded.

Optic Disc, Macula, and Retinal Nerve Fiber Layer Measurements Obtained by OCT in Thyroid-Associated Ophthalmopathy.

Aim. To compare the measurements of retinal nerve fiber layer (RNFL), macula and optic disc parameters obtained by optical coherence tomography (OCT), and intraocular pressure (IOP) between the patients with thyroid-associated ophthalmopathy (TAO) and healthy controls. Methods.

Ab-interno scleral suture loop fixation with cow-hitch knot in posterior chamber intraocular lens decentration.

Aim Of Study: To describe a simplified ab-interno cow-hitch suture fixation technique for repositioning decentered posterior chamber intraocular lens (PC IOL).

Materials And Methods: Two cases are presented with the surgical correction of decentered and subluxated IOL. Ab-interno scleral suture fixation technique with hitch-cow knot in the eye was performed with a ciliary sulcus guide instrument and 1 year follow-up was completed.
