Laser Diagnostic Technologies

Laser Diagnostic Technologies (LDT) was a medical technology company specializing in the development and commercialization of advanced diagnostic tools for ophthalmology. The company is best known for its GDx Nerve Fiber Analyzer, which utilizes scanning laser polarimetry to measure the thickness of the retinal nerve fiber layer. This technology provided clinicians with a non-invasive method for the early detection and monitoring of glaucoma by identifying structural changes before vision loss occurs. LDT's innovations significantly advanced the field of ophthalmic imaging and established a new standard for glaucoma management. The company was acquired by Carl Zeiss Meditec in 2004, and its technology was integrated into the Zeiss diagnostic portfolio.
