Half-dose photodynamic therapy versus 577 nm subthreshold pulse laser therapy in treatment-naive patients with central serous chorioretinopathy

Table 2 Final analysis: HD-PDT versus SPL after one/two treatment cycles

	HD-PDT (n = 49)	SLL (n = 46)	P-Value
Total observation time (weeks, median(IQR))	17.3 (9.9–24.2)	17.7 (9.0-25.5)	0.908*
Patients with second treatment (n,%)	22 (44.9)	20 (43.5)	0.889†
Change in BCVA (logMAR, median (IQR))	0.10 (0.0-0.2)	0.10 (0.0-0.2)	0.344*
Completely dry (n,%)	30 (61.2)	28 (60.9)	0.972†

Legends: * Mann-Whitney U Test, † Pearson’s chi² test. BCVA: Best corrected visual acuity, 95%CI: Confidence interval, IQR: Interquartile range, logMAR: Logarithm of the minimum angle of resolution, HD-PDT: Half-Dose photodynamic therapy, SD: Standard deviation, SPL: Subthreshold pulse laser
