Determination of Length of Interdigitation Zone by Optical Coherence Tomography and Retinal Sensitivity by Microperimetry and Their Relationship to Progression of Retinitis Pigmentosa

Table 1

Values of the parameters at the baseline and final examination.

	Baseline	Final	p value
Retinal sensitivity, dB	12.7 ± 4.65	10.1 ± 4.56	< 0.0001
ELM, μm	4966 ± 1977	4682 ± 1879	< 0.0001
EZ, μm	4171 ± 1924	3725 ± 1781	< 0.0001
IZ, μm	1576 ± 1111	1033 ± 976	< 0.0001

Data are the means ± SD. Paired t-test. ELM, external limiting membrane; EZ, ellipsoid zone; IZ, interdigitation zone.
