Outer Nuclear Layer as the Main Predictor to Anatomic Response to Half Dose Photodynamic Therapy in Chronic Central Serous Retinopathy

Table 3

Independent correlations between variables at baseline and anatomic response.

Independent variables at baseline	Correlation with anatomic response
Best-corrected visual acuity	rs (59) = −0.23,
Time from diagnosis	rs (57) = 0.05,
Central macular thickness	rs (59) = 0.15,
Outer nuclear layer	rs (59) = 0.416,
External limiting membrane	rs (59) = 0.261,
Ellipsoid zone	rs (59) = 0.278,
Interdigitation zone	rs (59) = 0.318,
Choroidal thickness	rs (59) = −0.098,
Subretinal fluid	rs (59) = 0.085,

Independent correlations between the anatomic response and the baseline retinal layers or baseline best-corrected visual acuity (BCVA). There is an independent correlation between baseline outer nuclear layer, external limiting membrane, ellipsoid zone, and interdigitation zone. rs = Spearman’s rho correlation;  =  value;  = statistically significant.
