Comparison of serum thiol-disulphide homeostasis and total antioxidant-oxidant levels between exudative age-related macular degeneration patients and healthy subjects.

Purpose: The purpose of the study was to calculate serum total oxidant status (TOS), total antioxidant status (TAS), and dynamic thiol-disulphide (T-D) homeostasis in patients with age-related macular degeneration (AMD), and compare the results with healthy individuals.

Methods: Thirty-three exudative AMD patients and 33 healthy controls were included in this case-control study. Participants' serum TAS and TOS levels were measured.

Intraocular pressure in infants and its association with hormonal changes with vaginal birth versus cesarean section.

To investigate cord arterial blood sample and the relationship between birth stress and intraocular pressure in infants at 5 min after delivery. The IOP measurements were taken using Tonopen-Avia tonometer to 158 newborns (158 eyes) at 5th min after birth, in a university hospital. Cord blood was collected within 3 min after delivery.

Comparison of retinal nerve fiber layer and macular thickness measurements with Stratus OCT and OPKO/OTI OCT devices in healthy subjects.

Aim: To compare retinal nerve fiber layer (RNFL) and macular thickness measurements obtained with the Stratus optical coherence tomography (OCT) and OPKO/OTI OCT devices.

Methods: Included in the study were 59 eyes of 30 participants. All measurements for each eye were done on the same day with both devices.

Effects of polyquaternium- and benzalkonium-chloride-preserved travoprost on ocular surfaces: an impression cytology study.

Purpose: To compare the toxicity effect of polyquaternium (PQ) and benzalkonium chloride (BAK) preservation of travoprost on the ocular surface.

Methods: This prospective study included 44 eyes of 44 patients with newly diagnosed glaucoma. Twenty-two patients used PQ-preserved travoprost (PQ group) and 22 patients used BAK-preserved travoprost (BAK group).

Peripapillary retinal nerve fiber layer changes in asymptomatic essential thrombocythemia patients.

Purpose: To investigate peripapillary retinal nerve fiber layer (RNFL) changes using optical coherence tomography (OCT) in patients with asymptomatic essential thrombocythemia (ET).

Materials And Methods: A consecutive case-control series of 30 patients with asymptomatic ET and age-similar, gender, refractive error, race-matched controls underwent a comprehensive eye examination and OCT of the peripapillary RNFL. Subjects with glaucoma, diabetes mellitus, hemoglobinopaties or other ocular diseases and those who underwent any retinal treatment were excluded.

The evaluation of physiological and biochemical parameters and the autonomic nervous systems of children with breath-holding spells.

Aim: The aim of this study was to investigate the physiological and biochemical parameters of children who are experiencing breath-holding spells (BHS) and to compare the function of their autonomic nervous systems with those of healthy children.

Patients And Methods: A total of 30 children (age range, 6 months-5 years) admitted for BHS were included in the study. The control group consisted of 30 age-matched and gender-matched healthy children.

Repeated bevacizumab injections versus mitomycin C in rotational conjunctival flap for prevention of pterygium recurrence.

Aims: To evaluate the efficacy of repeated bevacizumab injection in rotational conjunctival flap surgery versus rotational conjunctival flap with adjunctive mitomycin C (MMC) or rotational conjunctival flap alone.

Materials And Methods: Ninety eyes of 90 patients who underwent primary pterygium surgery with rotational flap were evaluated. Patients were randomly assigned to undergo conjunctival rotational flap alone (Group A) or conjunctival rotational flap with either 0.
