she was a known case of myopic choroidal neovascular membrane ( cnvm ) , which was treated with a photodynamic therapy and avastin anti - vascular endothelial growth factor intravitreal injection in both eyes 2 years ago . her best corrected visual acuity was 20/100 , n6 in both the eyes ( refractive error : 15.00 ds and 13.00 ds for right and left eye respectively ) . on examination following mp evaluation , she underwent mp-1 biofeedback training for 10 sessions each 10 min , on alternate days , for both eyes . a written informed consent was taken , and an approval from the institutional review board was obtained . distance visual acuity , near visual acuity , fixation , and mp tests were assessed again at the end of the biofeedback training ( i.e. , after 20 days ) and at the follow - up , a year later . mp was repeated using the follow - up function , which automatically retested the patient in exactly the same locations . the mp and fixation test were performed using mp-1 microperimeter ( nidek technologies ; podua , italy ) in central 20 area . the stimulus attenuation ranged from 0 to 20 db with goldmann size iii stimulus , the size of the target was kept 5 according to her visual acuity . each eye was assessed separately for fixation behavior , location and stability of the prl , scotoma size and density and central light sensitivity . to assess the fixation stability , movements of the fundus were tracked during the examination while the patient gazed at the fixation target [ fig . 1 ] . the autotracking system calculated the horizontal and vertical shifts relative to a reference frame and mapped the patient 's eye movements during the examination . mp audio biofeedback training was performed by asking the patient to move her eyes according to an audio feedback , which advised whether the patient was getting closer to the desired final fixation position . microperimetry-1 image of color topography and stability of fixation at baseline , end of the biofeedback training and at 1-year follow - up . fixation characteristics were taken as described by fuji et al . ; the standard of central fixation was defined to approximate a 2 diameter ( equals , 600  ) circle centered on the fovea . the scotoma density was defined based on the threshold values : normal function - threshold values of 10 db ; relative scotoma - threshold values of 10 db and an absolute scotoma was present if no threshold could be seen . best corrected visual acuity was 20/100 in both eyes before and after training and the same was maintained till the follow - up after a year . the mean retinal sensitivities before , after and at 1-year after training in the right eye were 2.9 db , 2.9 db and 3.7 db and in the left eye were 3.5 db , 3.7 db and 1.8 db . the fixation point in the 2 gravitation circle , following biofeedback training improved from 40% to 50% in the right eye and from 43% to 67% in the left eye . the prl , which was superior to the scotoma prior to and following the training , was maintained at the follow - up visit . the average eye speed , which was 0.19/s before bfd training , changed to 0.26/s following bfd training in the right eye and remained at 0.25/s at the follow - up visit . the average eye speed reduced from 0.36/s to 0.25/s in the left eye following bfd training and remained at 0.27/s at the follow - up visit [ figs . 2 and 3 ] . ( a ) fixation behavior in center 2 area 40% before training with average eye speed of 0.19/s . ( b ) fixation behavior in center 2 area 50% after biofeedback training with average eye speed of 0.26/s . ( c ) fixation behavior in center 2 area 65% at 1-year of follow - up training with average eye speed of 0.25/s left eye : fixation distribution : graph of fixation points versus radius in degree . ( a ) fixation behavior in center 2 area 43% before training with average eye speed of 0.38/s . ( b ) fixation behavior in center 2 area 50% after biofeedback training with average eye speed of 0.25/s . ( c ) fixation behavior in center 2 area 75% at 1-year follow - up with average eye speed of 0.27/s the fixation location was predominantly eccentric in the right eye before training ; it was poor central following bfd training and was maintained at 1-year follow - up . the fixation location was poor central in the left eye before training ; it was poor central following bfd training and was predominantly central at 1-year follow - up . this is the first report from india , which estimates the benefits of low vision rehabilitation using mp-1 bfd in macular pathology . this case showed good response after the bfd training , which was maintained at 1-year follow - up . our results showed that new prl ( trl ) increased fixation stability as well as retinal sensitivity . no significant changes in the visual acuity , mean retinal sensitivity and speed of eye movement were seen . nilsson et al . found an improvement in reading speed following eccentric viewing training demonstrated with scanning laser ophthalmoscopy microperimeter ( 9.0  5.868.3  19.4 with p < 0.001 ) . frennesson et al . used computer and video display based system for training eccentric viewing in macular degeneration with an absolute central scotoma , which showed a significant increase in reading speed . the bfd effect can be related to the brain 's ability to perceive an efficient prl for visual tasks . the audio feedback can help the brain to fix the trl by increasing the attentional modulation . sound perception increases the conscious attention of the patient , thereby facilitating the lock - in of the visual target and increasing the permanence time of the target itself on the retina . this mechanism probably facilitates stimuli transmission not only between intraretinal neurons , but also between the retina and brain where the highest degree of stimuli processing takes place , thereby supporting a  remapping phenomenon .  in summary , this case demonstrated successful biofeedback training in macular pathology . further studies are needed to evaluate the usefulness of this technique in bilateral macular diseases .
