<p>MP-1 microperimeter (NIDEK Technologies) is equipped with a visual rehabilitation tool used until now to rehabilitate patients with low visual acuity.

<p>Ten consecutive patients (7 females, 3 males; median age of 42.3 ± 11.63 years) with homonymous visual field defect resulting from lesions of the central visual pathways and foveal sparing were enrolled for visual rehabilitation with MP-1 microperimeter (NIDEK Technologies).

Background:
MP-1 microperimeter (NIDEK Technologies) is equipped with a visual rehabilitation tool used until now to rehabilitate patients with low visual acuity. Because the patterned stimulation might activate surviving neurons in areas of residual vision, in our work we want to verify the possibility to rehabilitate patients with visual field defects and foveal sparing, to obtain vision restoration and visual field enlargement.


Methods:
Ten consecutive patients (7 females, 3 males; median age of 42.3 ± 11.63 years) with homonymous visual field defect resulting from lesions of the central visual pathways and foveal sparing were enrolled for visual rehabilitation with MP-1 microperimeter (NIDEK Technologies). Subjects underwent an ophthalmic evaluation at baseline, after rehabilitative pathway performed by flickering pattern and at 3 months of follow-up. Outcomes measured included visual field exams and microperimetries.


Results:
Compared with the baseline time point, all patients showed a statistically significant reduction of the scotoma points and visual field Mean Deviation and a statistically significant increasing of the mean retinal sensitivity. All results showed a major statistical significance after 3 months since the end of the visual stimulation.


Conclusions:
The MP1 pattern stimulation is a valid method to perform a behavioral training and rehabilitate patients with visual field defects following lesions of the central visual pathways.
