For decades, precise observation and documentation of the optic nerve head has been essential for the diagnosis and management of glaucoma. In previous generations, physicians depended on ophthalmoscopic observations, colored drawings, and clinical notes to determine whether the nerve had been damaged by glaucoma.
Fundus photography provided a great leap forward in optic nerve head documentation and this was soon followed by stereophotography, which allowed nerve head contours to be visualized. Although photography allowed doctors to discard their colored drawing pencils, photography still does not provide enough precise information to detect subtle nerve head changes associated with disease progression.
The development of laser imaging techniques has allowed another advance to be made in the ability of eye care specialists to image and quantify optic nerve head contours. The Heidelberg Retinal Tomograph II (HRT II) uses confocal scanning laser ophthalmoscopy (CSLO) to produce pseudo-three-dimensional images of the nerve head. It also produces a set of precise numerical measurements that can be used to document nerve head status and changes.(18, 22, 23, 25, 27, 28, 31, 32, 35, 37, 40, 41)
This course focuses on the role of the HRT II in the diagnosis and management of glaucoma. It includes a description of HRT II technology along with clinical applications and case reports demonstrating its use.
