Association of presbyopic correction with changes in visual fields

The purpose of this study was to investigate the effect of presbyopic corre ction on changes in visual fields caused by an alteration in outflow of aqu eous humour. Visual fields were compared before and after introduction of p resbyopic correction in participants of the Melbourne Visual Impairment Pro ject. Height and slope of the 'Hill of Vision' were assessed by calculating median thresholds in the four sets of three eccentric points. Analysis of 101 eyes in the study group and 101 eyes in the control group shows higher decrease of the 'Hill of Vision' height in the group of participants who st arted wearing presbyopic correction, than in the group without presbyopic c orrection (P = 0.02). Intraocular pressure measured irrespectively of parti cipant's accommodative activity was not significantly different between the two groups at both time points. These data suggest that the use of presbyo pic correction is associated with changes in the visual field.
