Safety of accelerated corneal collagen cross-linking in keratoconus patients on the basis of macular segmentation.

Purpose: To investigate the safety of accelerated corneal collagen cross-linking (A-CXL) in patients with keratoconus on the basis of thickness analysis measurements of retinal layers and retinal morphology.

Study Design: This was a retrospective and comparative study.

Methods: The study included 64 eyes of 32 patients with keratoconus disease.

The Relationship Between Keratoconus Stage and the Thickness of the Retinal Layers.

Objectives: To examine the relationship between keratoconus (KC) stage and the thickness of the retinal layers.

Materials And Methods: Retinal layer thicknesses were compared between 85 eyes of 85 KC patients and 40 eyes of 40 controls similar in age, sex, and axial length. KC patients were staged as stage 1, 2, or 3 according to the Amsler-Krumeich staging system, and segmentation of the retinal layers was performed with spectral domain optical coherence tomography automatic segmentation program.

The short term effect of trehalose and different doses of sodium hyaluronate on anterior corneal aberrations in dry eye patients.

Aim: To evaluate the short-term effect of 0.15% sodium hyaluronate (SH), 0.20% SH, and Trehalose + 0.

The effect of posterior vitreous detachment on aflibercept response in diabetic macular oedema.

Purpose: To investigate the effect of posterior vitreous detachment (PVD) on aflibercept response in treatment-naïve diabetic macular oedema (DME).

Design: A retrospective cohort study.

Methods: One hundred and fifty eyes of 150 treatment-naïve patients with DME were enrolled.

Anterior chamber characteristics assessed by rotating Scheimpflug imaging in patients with retinitis pigmentosa.

Purpose: The aim of this study was to evaluate anterior segment parameters and corneal aberrations in patients with retinitis pigmentosa using Scheimpflug imaging and to compare the findings with those for healthy controls.

Methods: This single-center, case-control study included patients diagnosed with retinitis pigmentosa who were followed up at the Department of Ophthalmology of Kayseri Training and Research Hospital between February and June 2018. Age- and sex-matched healthy individuals with no known ophthalmologic disease formed the control group.
