The Heidelberg Retinal Tomography is a diagnostic procedure used in ophthalmology. The Heidelberg Retina Tomograph (HRT) is an ophthalmological confocal point scanning laser ophthalmoscope [ 1 ] for examining the cornea and certain areas of the retina using different diagnostic modules (HRT retina, HRT cornea, HRT glaucoma).
Scanning laser ophthalmoscopy developed as a method to view a distinct layer of the living eye at the microscopic level. The use of confocal methods to diminish extra light by focusing detected light through a small pinhole made possible the imaging of individual layers of the retina with greater distinction than ever before.

Medical optical imaging is the use of light as an investigational imaging technique for medical applications, pioneered by American Physical Chemist Britton Chance.Examples include optical microscopy, spectroscopy, endoscopy, scanning laser ophthalmoscopy, laser Doppler imaging, optical coherence tomography, and transdermal optical imaging.
In 1886 he came from Paris to Heidelberg to study under Prof. Dr. Otto Becker. It was in Heidelberg that he learned to use the newly invented ophthalmoscope (invented by the Heidelberg University Professor of Physiology from 1858 to 1871 Hermann von Helmholtz) to later operate on his own mother's eye.

Heidelberg retinal tomography (HRT), scanning laser polarimetry and optical coherence tomography are computerised techniques for imaging various structures of the eyes, including the optic disc. They quantify the nerve fiber layer of the disc and surrounding retina and statistically correlate the findings with a database of previously screened ...
The PASCAL (PAtterned SCAnning Laser) method of photocoagulation was initially developed at Stanford University.OptiMedica founders worked together at Coherent, and based on their experience in the ophthalmic laser industry, recognized the need for improved safety, precision, comfort and speed of photocoagulation procedures for eye diseases.
Ophthalmoscopy, also called funduscopy, is a test that allows a health professional to see inside the fundus of the eye and other structures using an ophthalmoscope (or funduscope). It is done as part of an eye examination and may be done as part of a routine physical examination .
