متن کاملPrevention of visual field defects after macular hole surgery.
BACKGROUND/AIM The pathogenesis of visual field loss associated with macular hole surgery is uncertain but a number of explanations have been proposed, the most convincing of which is the effect of peeling of the posterior hyaloid, causing either direct damage to the nerve fibre layer or to its blood supply at the optic nerve head. The purpose of this preliminary prospective study was to determ...

We thank Jiang and colleagues for their comments on our recent article comparing central and peripheral visual field (VF) loss in glaucoma. Their comments raise an excellent point—that sensitivity at greater levels of eccentricity to fixation are more variable both within and across individuals—a point also made in our original discussion. If we wanted to compare the percentage of test location...
