Precocious diagnosis of glaucoma: comparison between nerve fibre analyzer and blue/yellow perimetry

The authors briefly review the tests available for precocious diagnosis of glaucomatous neuropticopathy. They present a casefile of 54 ocular hyperten sive eyes examined by NFA and blue-on-yellow perimetry to verify the equiva lence of these two different tests in the precocious diagnosis of glaucoma. The results point up a perfect correspondence in 50% of the cases. They co nclude by stressing the necessity of having a screening available for the p recocious diagnosis of glaucoma with the use of more tests that have standa rdized and reliable parameters.
