LINARES GUERRA, Marilyn et al. Visual rehabilitation by means of MPI microperimeter in patients with macular hole and low vision. Rev Cubana Oftalmol [online]. 2011, vol.24, n.2, pp. 329-330. ISSN 0864-2176.

Objective: To evaluate the benefits of visual stimulation by using the MP1 microperimeter in patients with low vision due to macular hole, who were seen at low vision service of “Ramón Pando Ferrer" Cuban Institute of Ophthalmology during 2010. Methods: An experimental, case series type study was carried out. The following variables were studied before and after the rehabilitation: best near spectacle-corrected visual acuity with Zeiss chart and best distance spectacle-corrected visual acuity with Feinbloom chart, fixation stability and retinal sensitivity by means of the MP1 microperimeter and reading speed. Ten 10-minute sessions of stimulation weekly using the MP1 microperimeter biofeedback module were given. Statistical analysis was performed with paired Student’s t-test. P values less than 0,05 were considered statistically significant. Results: Distance and near visual acuity improved from 0,18 to 0,23, and from 0,21 at 0,51; retinal sensitivity increased from 2,69 to 7,86 dB, fixation stability was unstable (80.77 %), relatively unstable (15.38 %) and stable (3,85 %) before stimulation and after the sessions: not unstable, relatively unstable (30,77 %) and stable (69,23 %). The reading speed improved from 35 to 104 words per minute. Conclusion: Visual stimulation by using the MP1 microperimeter improved the visual performance of patients with macular hole and low vision.
