Abstract

Glaucoma is one of the leading causes of non-reversible blindness worldwide, and almost 6 million people are estimated to be impaired visually in advanced stage of glaucoma. Recently, several studies on glaucoma has been focused towards new therapeutic approaches based on mechanisms independent from IOP control. Effects of new therapeutic agents, visual psychophysical training, or complementary medications targeting optic pathways today seem to be a relevant and effervescent field of research. The goal of the study is to evaluate in glaucoma patients if a rehabilitative strategy with a biofeedback training with microperimetry may be useful after surgery in recovery visual performance even when visual field defects are present in IOP is well controlled environment. Were enrolled 24 patients (28 eyes) with Primary Open Angle Glaucoma (POAG) (mean 63 range: 49–75 years) from our Glaucoma Center after filtering surgery. All patients after one months from surgical intervention underwent to a complete ophthalmologic examination: IOP measurement, gonioscopy, visual field and SD-OCT at baseline of RNFL thickness. In some cases, were included in the study both eyes because in POAG frequently clinical conditions are different in each eye, and secondarily new fixation target retinal location (TRL) was chosen based on single eye retinal sensitivity. Best corrected visual acuity was significantly increased after the training from 0.61 to 0.479 (p = 0.00058) with no change in refractive error. After the biofeedback patients presented increased value in Mean retinal sensitivity from 14.91 to 15.96 (p = 0.0078).Fixation stabilitywas improved either according to Fuji classification (increased from 75.1 to 81.3% p = 0.0073) or BCEA value, reduced from 8.7 to 6.0 square degrees (p = 0.013) we noted a marked increase in this parameter with better performances and satisfaction by the patient. RFNL thickness: no change was noted (p = 0.505) in this value as an indicator of disease’s stability. Our data indicate that MP-3 Biofeedback may be a good strategy to reduce the impairment of the Glaucoma Patient.
