Detecting early changes in choroidal vascularity and thickness using optical coherence tomography in patients with corneal crosslinking for keratoconus.

Aim: To investigate changes in choroidal thickness and vascularity in keratoconus patients treated with corneal crosslinking.

Methods: This study evaluated 28 eyes of 22 patients with keratoconus who underwent corneal crosslinking. The choroidal thicknesses were evaluated on enhanced depth imaging optical coherence tomography at the preoperative and postoperative 3d, 1, and 3mo.

Antibacterial effects of nanoparticles, composite quantum dots and silk proteins attached to dental titanium alloy.

Purpose: To present the antibacterial effect of new generation boron-doped carbon quantum dots (B-CQD) and compare the antibacterial effect of silk sericin (SS), hydrolyzed silk peptide (HSP) and SS/HSP coated silver nanoparticle (AgNP) and B-CQDs on titanium alloy (Ti) surfaces.

Methods: SS and HSP were formed on the surface of the Ti alloy (Ti-SS/HSP). Different concentrations of citric acid and boric acid, B-CQDs and AgNP were attached to Ti-SS/HSP surfaces.

Pars plana vitrectomy combined with pan-retinal photocoagulation, Ahmed glaucoma valve implantation, and/or phacoemulsification for complicated neovascular glaucoma treatment.

Purpose: To present long-term results of pars plana vitrectomy combined with pan-retinal endolaser photocoagulation, Ahmed glaucoma valve implantation, and/or phacoemulsification in patients with complicated neovascular glaucoma.

Methods: The study comprised 15 eyes from 15 patients with neovascular glaucoma as a complication of diabetic retinopathy and owing to ischemic central retinal vein occlusion. There was a vitreous hemorrhage n all of the patients.

Assessment of ganglion cell complex, macular thickness, and optic disc parameters in keratoconus patients.

Purpose: Keratoconus (KC) is bilateral noninflammatory corneal disorder characterized by progressive corneal thinning, protrusion, and scarring. The purpose of this study was to evaluate ganglion cell complex(GCC), macula thickness(MT) and optic head disc parameters in keratoconus patients.

Methods: A hospital based prospective clinical case series was performed in Inonu University School of Medicine.

Corneal tattooing for esthetic purposes in patients with corneal opacities.

Purpose: This study evaluated corneal tattooing for esthetic purposes in patients with corneal opacification.

Methods: Eight eyes of eight patients were included in the study (four males and four females). Corneal tattooing was achieved by stromal puncture in five patients, femtosecond laser-assisted corneal tattooing in two patients, and femtosecond laser-assisted corneal tattooing and stromal needling (combined procedure) in one patient.
