Purpose To examine the neuronal structural integrity of cornea and retina as markers for neuronal degeneration in nonproliferative diabetic retinopathy (NPDR). Methods Participants were recruited from the broader Brisbane community, Queensland, Australia. Two hundred forty-one participants (187 with diabetes and 54 nondiabetic controls) were examined. Diabetic retinopathy (DR) was graded acco...

purpose: to determine the sensitivity and specificity of posterior corneal elevation in discriminating keratoconus and subclinical keratoconus from normal corneas by galilei and orbscan ii diagnosed on the basis of topography. methods: three groups (keratoconus, subclinical keratoconus and normal) were evaluated with galilei and orbscan ii and results were compared to those obtained by gold sta...

purpose: to evaluate the efficacy of riboflavin administration and ultraviolet a (uva) cross-linking on advanced symptomatic bullous keratopathy (bk). methods: 10 patients with symptomatic pseudophakic bullous keratopathy (pbk) were included. slit-lamp examination, visual acuity, foreign body sensation (fbs) and corneal thickness as measured by pentacam, were performed before corneal cross-link...

purpose: to evaluate the ability to predict visual outcome after penetrating keratoplasty (pkp) in patients with pseudophakic or aphakic corneal edema (pce or ace). methods: medical records of 34 patients (34 eyes) who underwent pkp for pce or ace during 1994-2004 in ahvaz were retrospectively analyzed for variables in the history and ocular examination before pkp and visual outcome after pkp. ...

purpose : to compare central corneal thickness (cct), corneal endothelial cell density, and lens capsule thickness in normotensive patients with and without pseudoexfoliation syndrome (pxs) methods : this was a prospective, comparative, descriptive study. normotensive candidates for cataract surgery with (study group) and without (control group) pxs were enrolled in the study. cct and corneal e...

purpose : to evaluate the correlation of central corneal thickness (cct) with refractive error and keratometry in a group of patients eligible for laser keratorefractive surgery, which may serve as a bias in studies on intraocular pressure (iop) measurement methods : in a cross sectional observational study, the right eyes of 340 patients who underwent laser keratorefractive surgery during the ...

results the mean udva (logmar) improved significantly from 1.13 ± 0.21 preoperatively to 0.24 ± 0.13 postoperatively (p < 0.001), and the mean cdva (logmar) improved significantly from 0.39 ± 0.12 to 0.19 ± 0.09 (p < 0.001). the mean cylinder of manifest refraction decreased significantly by 4.00 diopter (d) (p < 0.001). the mean spherical equivalent error (se) decreased significantly from −6.0...

AIMS/BACKGROUND Interrupted corneal sutures are used routinely by many cataract and corneal surgeons. A slim compact knot facilitates burial and allows atraumatic suture removal, with decreased risk of wound dehiscence. The size and morphology of knots tied in different configurations were investigated. METHODS 10-0 nylon suture material was used to tie knots on porcine corneal cataract secti...

BACKGROUND Cataract extraction is the most common intraocular surgery taught to residents. AIM This study aims to review the complications of trainee-performed extracapsular cataract extraction (ECCE) so as to identify the steps in which the trainee can benefit from closer supervision and practice. SUBJECTS AND METHODS This was a descriptive retrospective study of complications in the initi...

PURPOSE Colostrum has been proposed to treat severe dryness and problematic eye lesions showing a beneficial effect. The aim of the study was to investigate the effect of 2-fucosyl-lactose, a natural sugar present in the human colostrum, in an experimental dry eye. METHODS Dry eye was induced in adult male New Zealand albino rabbits by topical administration of 1% atropine. Tear volume (Schir...
