PURPOSE To report the clinical, confocal scan, and histopathologic features of nocardia keratitis in a patient who developed bilateral infection following photorefractive keratectomy (PRK). CASE REPORT A 23-year-old woman underwent bilateral PRK for low myopia. On postoperative day 3, dense central stromal infiltrates were noticed in both eyes. Empirical antibiotic therapy was initiated which...

An optical model of an ultrathin scanning fiber endoscope was constructed using a non-sequential ray tracing program and used to study the relationship between fiber deflection and collection efficiency from tissue. The problem of low collection efficiency of confocal detection through the scanned single-mode optical fiber was compared to non-confocal cladding detection. Collection efficiency i...

Confocal microscopy has several advantages over wide-field microscopy, such as out-of-focus light suppression, 3D sectioning, and compatibility with specialized detectors. While wide-field microscopy is a faster approach, multiplexed confocal schemes can be used to make confocal microscopy more suitable for high-throughput applications, such as high-content screening (HCS) commonly used in drug...

Fast T-scanning (transverse scanning, en-face) was used to build B-scan or C-scan optical coherence tomography (OCT) images of the retina. Several unique signature patterns of en-face (coronal) are reviewed in conjunction with associated confocal images of the fundus and B-scan OCT images. Benefits in combining T-scan OCT with confocal imaging to generate pairs of OCT and confocal images simila...

purpose: to evaluate corneal endothelial cells of donors who died from aluminum phosphide intoxication. methods: endothelial cell count and quality of eight corneas from four donors with aluminum phosphide intoxication were evaluated by slit lamp biomicroscopy and specular microscopy at the eye bank of i.r. iran. confocal scan examination was carried out only in one of the recipients. results: ...

purpose: to characterize keratic precipitate (kp) morphology in different forms of uveitis. methods: one hundred and twenty nine eyes of 93 patients with different forms of uveitis underwent confocal scan and the morphology of kps were determined. differences in kp morphologies among different uveitic groups were evaluated.  results: age ranged from 14 to 67 years (mean: 32.5±11.2) and 58 cases...
