— Visual fields. This method of visual field assessment relies on comparing the patient's visual field with your own and, therefore, for it to work: you need to position yourself, the patient and the target correctly (see details below) you need to have normal visual fields and a normal-sized blindspot; Visual field assessment. 1. Sit directly ...

— To answer your question, my Fieldmaster seems to be a nice gun for the money. In the field, I've been a Benelli M2 fan for some time, but have felt they are overpriced for what they are. I only have 8-10 shots through the Fieldmaster now, but took it out of the box and took it down, lubricated it and hunted the next day with no problems.

— Why is the visual field test important? The visual field test is important in the diagnosis of retinal conditions, and identification of retinal nerve damage. Any nerve damage is usually permanent, so early detection is crucial. If retinal nerve damage (a scotoma) is detected, its size and shape will facilitate staging of an ocular disease.
