The Far Nasal Part of the Visual Field - Part I.

Aims: The aim of the study was to determine the limits of the far nasal part of the visual field.
Material and Methods: Visual field examination was performed in 15 healthy subjects (30 eyes), specifically nine women aged 20-43 years and six men aged 22-35 years. All eyes were found to have physiological ocular findings and visual acuity of 1.0 with correction less than or equal to 3 diopters. The visual field was examined with a Medmont M700 instrument by shifting the fixation point 40 degrees temporally and simultaneously turning the head nasally, with a spatial accommodation program. A total of 89 examination points were included using flicker stimuli.
Results: The far nasal limit of the visual field reached 100° in 13.3% of eyes, 105° in 20% of eyes and up to 110° in 66.7% of eyes.
Conclusion: The limit of the far nasal part of the field of vision reached 100-110 degrees (when nose shielding was eliminated).
