The introduction of spectral domain optical coherence tomography (SD-OCT) has enhanced Vitreoretinal Interface (VRI) imaging considerably and facilitated the diagnosis, followup, prognosis determination, and management of VRI-associated pathologies. HR-OCT became a common practical tool seen in almost every ophthalmology practice. Knowledge of SD-OCT image(More)
PURPOSE To provide a comprehensive study of the biological role and therapeutic potential of six endogenous epidermal growth factor receptor (EGFR) ligands in corneal epithelial homeostasis. METHODS Kinetic analysis and dose response curves were performed by using in vitro and in vivo wound-healing assays. Biochemical assays were used to determine(More)
PURPOSE To investigate the possible toxic effect of oxygen on lenses in an organ culture. METHODS Bovine lenses were exposed to four different combinations of ambient pressure and oxygen concentration in an organ culture throughout a 7-day period. Lens transparency, histology, enzymatic activities, and photomicrographs were compared in study and control(More)
PURPOSE To demonstrate the production of hemoglobin by human retinal pigment epithelium (RPE). METHODS Proteomic analysis using 10 donor eyes identified hemoglobin as a major constituent of soluble human RPE proteome. Western blot analysis, RT-PCR, and immunocytochemistry were used to confirm the RESULTS The presence of erythrocyte-specific proteins(More)
PURPOSE To mathematically analyze and to clinically describe specific anatomic foveal configurations predisposing to the formation of macular holes in comparison with normal foveal anatomy. METHODS In a retrospective observational case-control series, a total of 3882 optical coherence tomography (OCT) foveal thickness maps were analyzed; 96 foveal maps(More)
PURPOSE To report on endophthalmitis occurrence and associated risk factors following the intravitreal injection of anti-VEGF agents based on a review of published literature. MATERIALS AND METHODS A Medline search was performed using the terms "bevacizumab" and "ranibizumab". A total of 534 English-language articles of varying design and published from(More)
PURPOSE To mathematically analyze anatomical changes that occur in the normal fovea during aging. METHODS A total of 2912 spectral-domain optical coherence tomography (SD-OCT) normal foveal scans were analyzed. Subjects were healthy individuals, aged 13 to 97 years, with visual acuity ≥20/40 and without evidence of foveal pathology. Using automated(More)
BACKGROUND The purpose of this study was to compare postoperative intraocular pressures and percentage of vitreous cavity gas fill one day following 25-gauge pars plana vitrectomy with 20% versus 25% sulfur hexafluoride (SF6) gas fill. METHODS This was a retrospective review of 187 consecutive cases of 25-gauge pars plana vitrectomy with complete(More)
