Blue-yellow perimetry in patients with ocular hypertone

The authors report the data of the blue-yellow (B-Y) perimetry compared with the Standard perimetry in normal subjects with endocular hypertension or with initial glaucoma. With the aim of evaluating the relationship with chromatic sense deficits, precociously found in glaucoma, the F-M 100 Hue test and Lanthony D 15 Desaturé test were done. Checks were made of refraction, visual acuity, pupil diameter and assumption of medications. Sensitivity reduction in eyes with initial glaucoma is highly significant with the B-Y perimetry. Pupil diameter reduction is quite uninfluential while the chromatic sense shows some quantitative and qualitative deficits.
