In this study, the PhNR of the RETeval was compared following glaucoma filtration surgery in patients with and without choroidal detachment after surgery. A functional improvement of the ganglion cell function (PhNR measurement) was observed after surgery. The presence of choroidal detachment appears to arrest the improvement of the ganglion cell function and less improvement was seen after surgery when choroidal detachment was present.
In this study the ERG PhNR measurement result did improve less after Glaucoma filtration surgery when choroidal detachments were present as compared to the improvement after filtration surgery with no choroidal detachments.
