Effect of Nonoverlapping Visual Field Defects on Vision-related Quality of Life in Glaucoma.

Purpose: Glaucoma patients may be considered to have normal vision as long as each point of visual space is perceived by at least 1 eye, that is, with an intact binocular visual field (VF). We aimed to investigate the effect of nonoverlapping VF defects on vision-related quality of life (VR-QoL) in glaucoma.

Design: Cross-sectional study.

Clinical Outcomes of Modified versus Traditional Technique for the Surgery of Hydatid Cyst of the Liver: A Case Control Study.

BACKGROUND is a parasitic infection most commonly involving the liver. Iran is a hyperendemic area for this disease according to WHO. Despite improvements in medical and interventional radiological techniques, surgery remains the gold standard of treatment; however evidence on different surgical modalities were explained.

Corneal Epithelial Thickness Mapping After Photorefractive Keratectomy for Myopia.

Purpose: To evaluate the longitudinal changes in epithelial thickness after photorefractive keratectomy (PRK) and correlate these with refractive changes.

Methods: This prospective study included 52 eyes of 52 candidates for myopic PRK. Along with standard ophthalmic examinations, corneal epithelial thickness mapping by anterior segment optical coherence tomography was performed.

Predictors of Successful Outcome following Intrastromal Corneal Ring Segments Implantation.

: To assess the preoperative visual, refractive, corneal topo/tomographic, aberrometric and biomechanical parameters as predictive factors of a successful outcome 6 months following intrastromal corneal ring segments implantation. : Sixty-eight keratoconus eyes implanted with Keraring using femtosecond laser technology were assessed. The preoperative assessed parameters included uncorrected and corrected distance visual acuity (UDVA & CDVA), refraction, placido-disk based topography using TMS-4, Scheimplfug tomography using Pentacam HR, corneal biomechanical assessments using Ocular Response Analyzer (ORA) and the wavefront analysis using i-Trace aberrometer.
