What Does Laser Interferometry Diagnose?

Laser interferometry is a cutting-edge, non-invasive diagnostic tool that uses precise laser-based technology to evaluate various eye conditions. Its accuracy and reliability have made it a cornerstone of modern ophthalmology. Before delving into the specific conditions it can diagnose, it’s helpful to understand two key terms used to evaluate diagnostic tools: positive predictive value (PPV) and negative predictive value (NPV). PPV refers to the likelihood that a positive test result accurately identifies a disease, while NPV indicates the likelihood that a negative result correctly rules out a disease. For example, a diagnostic tool with a PPV of 95% means that 95 out of 100 positive results are accurate, while an NPV of 98% means 98 out of 100 negative results are correct. Laser interferometry excels in both measures, making it a trusted method for diagnosing a wide range of eye conditions. Below, we explore how laser interferometry is used to diagnose common ocular diseases.
