Purpose: To determine the normative database of macular and retinal nerve fiber layer (RNFL) thickness parameters in healthy Turkish children by OCT.

Methods: 318 eyes of 318 children (138 boys, 183 girls) aged between 3 and 17 years were evaluated. The children were scanned by Cirrus HD-OCT (Carl Zeiss Meditec) to measure the macula, RNFL, and optic nerve head parameters.

Article Synopsis
  • The study evaluated the consistency and agreement in anterior segment measurements using two different devices: the Galilei dual Scheimpflug analyzer and the Nidek AL Scan on both keratoconic and normal eyes.
  • Measurements included central corneal thickness, anterior chamber depth, keratometry readings, and white-to-white distance, with excellent repeatability found for both devices in all parameters for normal eyes.
  • While both devices are interchangeable for most measurements in normal eyes, significant differences were noted in keratoconic eyes regarding central corneal thickness and keratometry measurements, indicating they should not be used interchangeably for these specific parameters.

Purpose: To investigate the association between central choroidal thickness (CT), axial length (AL), age, gender, and refractive error in a healthy pediatric population using optical coherence tomography (OCT).

Methods: This institutional study involved 137 healthy children (57 boys, 80 girls) aged between 4 and 18 years. Each child underwent a dilated eye examination, cycloplegic refraction, and AL measurement using a Nidek AL-Scan optical biometer.

Purpose: To evaluate the safety and efficacy of intravitreal dexamethasone implant (Ozurdex) in patients with chronic diabetic macular edema (DME) resistant to prior intravitreal bevacizumab (IVB) treatment.

Materials And Methods: Thirty eyes of 30 patients were administered intravitreal Ozurdex and examined at baseline and 1, 3, and 6 months postinjection in this prospective study. Main outcomes were the best corrected visual acuity (BCVA, logMAR), central foveal thickness (CFT), mean cube volume (MCV), and intraocular pressure (IOP).

Purpose: To evaluate the changes of anterior segment parameters following the topical instillation of cyclopentolate hydrochloride 1% with the Galilei dual-Scheimpflug analyzer (GSA) (Ziemer Ophthalmology Co., Port, Switzerland) in healthy children.

Methods: Fifty children (29 boys, 21 girls) were evaluated before and 60 minutes after instillation of three drops of 1% cyclopentolate hydrochloride using the GSA.

Article Synopsis
  • The study aimed to analyze choroidal thickness (CT) in eyes with hyperopic anisometropic amblyopia compared to fellow non-amblyopic and age-matched normal eyes using SD-OCT.
  • A total of 106 participants, including 53 with amblyopia and 53 controls, underwent eye examinations to measure axial length and choroidal thickness in the subfoveal area.
  • Results showed that the subfoveal CT in amblyopic eyes was significantly thicker than both fellow and control eyes, indicating that choroidal thickness is affected in hyperopic anisometropic amblyopia.

Purpose: To identify the distribution, variation, and determinants of ganglion cell-inner plexiform layer (GC-IPL) thickness in healthy Turkish children measured by high-definition optical coherence tomography (HD-OCT).

Patients And Methods: This institutional study involved 296 eyes from 296 healthy children aged between 3 and 17 years. Each child underwent a dilated eye examination, cycloplegic refraction, and axial length measurement using Nidek AL-Scan optical biometer.

Background: To evaluate the potential efficacy and safety of inner limiting membrane (ILM) staining with brilliant blue G (BBG) under air infusion.

Methods: 63 patients, treated by one surgeon with macular hole or idiopathic epiretinal membrane were evaluated prospectively. BBG was applied under air infusion in 38 patients (group 1), and injected into the vitreous cavity in 25 (group 2).

Uveitis, glaucoma, and cystoid macular edema frequently develop in patients with juvenile idiopathic arthritis. The authors describe a case of cystoid macular edema associated with juvenile idiopathic arthritis that had not responded to intravitreal triamcinolone acetonide and bevacizumab but improved significantly following intravitreal injection with a dexamethasone 0.7 mg implant.
