Visual Recovery after Primary Retinal Detachment Surgery: Biofeedback Rehabilitative Strategy

Table 1

Retinal sensitivity and bivariate contour ellipse area (BCEA) obtained in the two groups.

	Baseline	After BF
Retinal sensitivity, dB
Group A	9.84 ± 2.03	15.42 ± 3.76
Group B	9.71 ± 2.21	10.2 ± 3.36
value	0.83	<0.001
LogBCEA, deg^2
Group A	0.48 ± 0.17	0.04 ± 0.03
Group B	0.49 ± 0.2	0.40 ± 0.31
value	0.87	<0.001

BF: biofeedback; dB: decibel; logBCEA: logarithmic transformation of bivariate contour ellipse area; all data are expressed as mean ± standard deviation; value is calculated between groups by unpaired -test.
