abstract = {Purpose: To assess binocular visual performance by means of binocular summation
on visual function after inducing monocular forward scattering, and to study
the influence of interocular differences on ocular parameters.
Methods: Seven young healthy subjects were recruited. Four Bangerter foils and
five fog filters were used to induce monocular forward scattering. To analyse the
impact of the scatter, visual acuity, contrast sensitivity, visual discrimination capacity
and distance stereoacuity were measured binocularly with the filter placed over
the dominant eye. Additionally, interocular differences were calculated for four
ocular parameters: the Objective Scatter Index (OSI), Strehl ratio (SR), modulation
transfer function cut-off
(MTF cut off) and straylight (log[s]). Binocular summation
was determined for these visual functions.
Results: A statistically significant deterioration in visual acuity, contrast sensitivity
and stereoacuity was seen for all of the filter conditions with respect to the natural
state (baseline), with the largest change being recorded for the Bangerter foils.
Similarly, the interocular difference for the three retinal image quality parameters
(OSI, SR and MTF cut-off)
and log(s) increased significantly for the Bangerter foil
condition, but not for the fog filters (except log(s)). Binocular summation declined
gradually with the Bangerter foils, but not for the fog filters. Statistically significant
correlations were found, that is, the greater the interocular differences, the
lower the binocular summation of the visual functions and the greater the distance
stereoacuity.
Conclusion: Increased forward scattering in the dominant eye resulted in interocular
differences, which reduced the overall binocular visual performance, including
the binocular summation of several visual functions and distance stereoacuity. The
results suggest that marked interocular differences in ocular parameters should be
avoided in cases of ocular pathology, amblyopia and emmetropisation procedures
(such as refractive surgery) or a monovision correction for presbyopia.},
