One-Year Results of Photodynamic Therapy Combined with Intravitreal Ranibizumab for Exudative Age-Related Macular Degeneration

Scatter plots showing correlations between visual acuity and grades of the inner and outer segments of the photoreceptors (IS/OS). Visual acuity was expressed as the logarithm of minimal angle of resolution (logMAR). (a) Scatter plot at baseline. There was a significant negative correlation between visual acuity at baseline and IS/OS grade at baseline (Speaman correlation coefficient [𝑟_𝑠]=−0.429;𝑃<0.01). (b) Scatter plot at 12 months. There was a significant negative correlation between visual acuity at 12 months and IS/OS grade at 12months (𝑟_𝑠=−0.687;𝑃<0.01).
