Abstract Details


To compare the extension of peripheral visual field in patients before and after cataract surgery and to evaluate whether Goldman kinetic perimetry can be used as an objective measurement of negative dysphotopsia (ND).


University Eye Clinic, Maastricht University Medical Center, Maastricht, The Netherlands.


Goldman kinetic perimetry was performed with V-4 target. Inclusion criteria were best corrected visual acuity of more than 0.6 Snellen and no history of visual field loss. The extension of the visual field was assessed in four quadrants: superior temporal (STQ), inferior temporal (ITQ), superior nasal (SNQ) and inferior nasal (INQ). In the control group, ten patients were evaluated before and one month after cataract surgery. The postoperative data of the control group were compared to the measurements of nine pseudophakic patients with bothersome ND from the same age group.


The extension of visual field did not change after cataract surgery in the control group. Patients with ND had smaller visual fields than the pseudophakic patients from the control group. Mean difference was 6 degrees in the STQ (p = 0.2), 15 degrees in the ITQ (p < 0.05), 7 degrees in the INQ (p < 0.05) and 5 degrees in the SNQ (p = 0.07). In three patients, a shadow could be drawn in the STQ and the ITQ during perimetry and position of this shadow matched their subjective description of ND.


The extension of peripheral visual field did not change after uncomplicated cataract surgery. Patients with negative dysphotopsia had smaller peripheral visual fields compared to the control group of the same age. In addition, the position of a shadow could be drawn in some of these patients during perimetry. We propose that Goldman kinetic perimetry can be used for objective evaluation of negative dysphotopsia.
