A low-cost optical pachymeter for the diagnosis of glaucoma and ocular hypertension

Glaucoma and ocular hypertension are major causes of vision loss worldwide. Recent clinical studies have highlighted the importance of central corneal thickness in diagnosing these disorders. However, current instrumental methods of measuring corneal thickness are not ideal for widespread clinical deployment. Here we compare the existing state of the art in corneal pachymetry with a novel, simple optical technique that will allow for the use of corneal pachymetry as a diagnostic tool in a non-research clinical setting.
