AIMS To report the appearances of cornea guttata and Fuchs' endothelial dystrophy from white light confocal microscopy. METHODS Seven eyes of four consecutive patients with cornea guttata were prospectively examined. Of the seven eyes, three also had corneal oedema (Fuchs' dystrophy). In vivo white light tandem scanning confocal microscopy was performed in all eyes. Results were compared with...

Confocal microscopy, which is a major advance upon normal light microscopy, has been used in a number of scientific fields. By confocal microscopy techniques, cells and tissues can be visualized deeply, and three-dimensional images created. Compared with conventional microscopes, confocal microscope improves the resolution of images by eliminating out-of-focus light. Moreover, confocal microsco...

PURPOSE To report a case of insect corneal foreign body with in vivo confocal microscopy performed. METHODS Clinical presentation, clinical pictures, and treatment are discussed. Confocal microscopy of the injured cornea was performed in areas showing foreign bodies with and without infiltrations seen under the slit-lamp. CONCLUSION Confocal microscopy is useful in detection of subtle infla...

OBJECTIVES We explore the clinical potential of reflectance and fluorescence confocal microscopy to image the morphologic and biochemical changes associated with precancer, in order to aid in the detection and diagnosis of cervical dysplasia. METHODS Cervical epithelial tissue samples imaged ex vivo or in vivo were obtained from M. D. Anderson Cancer Center and Lyndon B. Johnson Hospital in H...

Visual inspection may fail to accurately evaluate field cancerisation (subclinical actinic keratoses [AKs]). We aimed to describe field cancerisation by confocal reflectance microscopy and changes induced by the application of 3% diclofenac sodium gel in 2.5% hyaluronic acid. Fourteen male patients, > 50 years old, with AKs on the bald scalp were included. Clinical examination, confocal microsc...

A new microscopy technique is introduced, image scanning microscopy (ISM), which combines conventional confocal-laser scanning microscopy with fast wide-field CCD detection. The technique allows for doubling the lateral optical resolution in fluorescence imaging. The physical principle behind ISM is similar to structured illumination microscopy, by combining the resolving power of confocal-lase...

We show the applicability of 4Pi-confocal microscopy to three-dimensional imaging of the microtubule network in a fixed mouse fibroblast cell. Comparison with two-photon confocal resolution reveals a fourfold better axial resolution in the 4Pi-confocal case. By combining 4Pi-confocal microscopy with Richardson-Lucy image restoration a further resolution increase is achieved. Featuring a three-d...

BACKGROUND Spitz nevus is a benign melanocytic lesion sometimes mistakenly diagnosed clinically as melanoma. OBJECTIVE Our aim was to evaluate in vivo reflectance-mode confocal scanning laser microscopy (CSLM) aspects of globular Spitz nevi and to correlate them with those of surface microscopy and histopathology. METHODS A total of 6 Spitz nevi, with globular aspects on epiluminescence obs...

PURPOSES To describe corneal changes seen on in vivo confocal microscopy in patients with total limbal stem cell deficiency and to correlate them with cytological findings. METHODS A prospective case series including 13 eyes (8 patients) with total limbal deficiency was carried out. Stem cell deficiency was diagnosed clinically and by corneal impression cytology. Confocal images of the centra...

BACKGROUND Risks associated with pediatric reconstructive heart surgery include injury of the sinoatrial node (SAN) and atrioventricular node (AVN), requiring cardiac rhythm management using implantable pacemakers. These injuries are the result of difficulties in identifying nodal tissues intraoperatively. Here we describe an approach based on confocal microscopy and extracellular fluorophores ...
