corneal transplantation is the most common and successful form of solid organ transplantation with a 2-year survival rate of over 90% in low risk cases. this high success rate may be due to the immune privileged status of the cornea, acaid (anterior chamber associated immune deviation) induction phenomena and secretion of inhibitory molecules by corneal cells such as il1-ra, il-1a and fas ligan...

the objectives of this study were to define the clinical risk factors, microbiological spectrum, and visual outcome of bacterial keratitis at shahid sadoughi hospital (yazd, iran). a crosssectional prospective study, identified 80 cases of microbial keratitis from march 1999 to march 2001. inclusion criteria were presence of corneal stromal infiltrate in slit lamp examination, and microbiologic...

The purpose of this study was to evaluate posterior corneal surface variation after femtosecond laser-assisted keratomileusis in patients with myopia and myopic astigmatism. Patients were evaluated by corneal tomography preoperatively and at 1, 6, and 12 months. We analyzed changes in the posterior corneal curvature, posterior corneal elevation, and anterior chamber depth. Moreover, we explored...

With the rapid development of computer science and technologies in recent years, there has been dramatic advance in anterior segment imaging. As we have mentioned in the call for papers for this special issue, manuscripts are covering the topics of anterior segment imaging techniques including anterior segment optical coherence tomography (OCT), specular microscopy, corneal topography, confocal...

Fluorophotometry was carried out in nine cases of unilateral non-traumatic rhegmatogenous retinal detachment successfully treated by a combination of local buckling and an encircling procedure with a silicone band. After topical instillation of fluorescein the change in its concentration in the anterior chamber was followed, from which the loss rate of the dye from the anterior chamber (k0) and...

PURPOSE To develop rapid image processing techniques for the objective analysis of corneal in vivo confocal micrographs. METHODS Perpendicular central corneal volume scans from healthy volunteers were obtained via laser in vivo confocal microscopy. The layer in each volume scan that contained the nerve plexus was detected by applying software operators to analyze image features on the basis o...

PURPOSE To overcome the anterior corneal mosaic (ACM) phenomenon in in vivo confocal laser scanning microscopy (CLSM) and to reconstruct undistorted images of the subbasal nerve plexus (SNP), facilitating morphometric analysis in the presence of ACM ridges. METHODS CLSM was performed in five healthy volunteers. An original image processing algorithm based on phase correlation was used to anal...

A growing cataract can be detected at the molecular level using the technique of dynamic light scattering (DLS). However, the success of this method in clinical use depends upon the precise control of the scattering volume inside a patient’s eye and especially during patient’s repeat visits. This is important because the scattering volume (cross-over region between the scattered light and incid...
