Comparison of glaucoma progression rate in glaucoma patients at different stages using guided progression analysis with optical coherence tomography.

Background: The aim of the present study was to compare the rates of change in Ganglion Cell- Inner Plexiform Layer (GCIPL) and Retinal Nerve Fiber Layer (RNFL) thickness, as measured by Optical Coherence Tomography (OCT) Guided Progression Analysis (GPA) program in control group, Primary Open Angle Glaucoma (POAG) and Pseudoexfoliation Glaucoma (PXG) eyes.

Methods: 60 POAG and 60 PXG patients and 30 control group patients were included in the study. Patients diagnosed with glaucoma were divided into two groups as mild (Mean deviation (MD) > -6.

Late corneal ectasia after penetrating and deep anterior lamellar keratoplasty for keratoconus.

Aim: To investigate tomographic features of late corneal ectasia after keratoplasty for keratoconus and compare penetrating keratoplasty (PK) and deep anterior lamellar keratoplasty (DALK) in terms of incidence, time of onset and risk factors of corneal ectasia.

Methods: Sixty eyes with PK and 30 eyes with DALK operated between 1999 and 2021 were analyzed. Final Pentacam scans were evaluated together with vision and previous topographies.

Comparison of autologous serum and platelet-rich plasma in the treatment of severe dry eye and persistent epithelial defects.

Purpose: To compare the efficacy of topical autologous serum and platelet-rich plasma (PRP) in patients with severe dry eye and persistent epithelial defects.

Methods: Sixty-seven eyes of 42 patients including 12 Sjogren, 11 meibomian gland dysfunction, 8 post penetrating keratoplasty, 5 acne rosacea, 5 chemical burn and 3 neurotophic keratopathy were analyzed. Best corrected visual acuity, Schirmer, Ocular Surface Disease Index (OSDI), tear break-up time, Oxford staining scores were measured before the treatment and 1 month.

Long-term outcomes of transcanalicular laser dacryocystorhinostomy versus endonasal dacryocystorhinostomy and a review of the literature.

Objective: The aim of this study was to compare the efficacy of endonasal dacryocystorhinostomy (EDCR) compared with transcanalicular laser DCR (TL-DCR).

Materials And Methods: This retrospective study and systematic review included patients that underwent DCR for nasolacrimal duct obstruction at our tertiary academic care hospital between January 2013 and December 2017. TL-DCR and EDCR were performed on 42 (group 1) and 45 (group 2) patients, respectively.

Long-Term Endothelial Cell Viability After Deep Anterior Lamellar Versus Penetrating Keratoplasty for Keratoconus.

Objectives: We compared long-term endothelial cell survival after penetrating versus after deep anterior lamellar keratoplasty for keratoconus.

Materials And Methods: We retrospectively compared 64 eyes of 55 patients who had penetrating keratoplasty and 40 eyes of 37 patients who had deep anterior lamellar keratoplasty for keratoconus (October 2003-February 2021). Best-corrected visual acuity, Goldmann applanation tonometry, fundus examination with 90D lens, and specular microscopy with CEM-530 (Nidek) were performed preoperatively and every 6 months postoperatively.
