Confocal scanning laser ophthalmoscopy through the Heidelberg Retina Tomograph (HRT) provides a rapid, safe, noncontact, and non-invasive imaging of the optic disc in three-dimensions through its precise detailed information about the optic disc. The HRT has been utilized as an adjunct to the clinical exam to aid in the diagnosis and management of glaucoma. Glaucoma is an optic neuropathy with characteristic visual field loss. It’s a chronic disease that must be longitudinally assessed and treated based on the appearance of the optic nerve and an evaluation of its function.
Prior to the advent of confocal scanning laser ophthalmoscopy, the detection of progressive glaucomatous change in the optic disc was primarily done through clinical examination and optic disc photos. But this method not only had high inter- and intra-observer variability, but poor reproducibility as well. Background…
