HRT

HRT stands for Heidelberg Retinal Tomograph … but this is hard to pronounce so we just call it “HRT”. This is an imaging test used primarily to photograph the optic disk in people with glaucoma.  The HRT uses a scanning laser to create a three-dimensional map of the optic nerve that can be used to track glaucomatous cupping and detect nerve damage from advancing glaucoma. The laser photograph is painless and safe. HRT can also stand for “hormone replacement therapy” or “hostage rescue team.”
