Differences in fundus images between methods.

	ODS		SRD		MT
	Negative	Positive	Negative	Positive	Negative	Positive
FP	43	19	40	22	53	9
FFA	52	10	33	29	48	14
OCT	57	5	31	31	37	25

There are differences in the proportions of ODS-positive patients according to each of the three fundus imaging methods. The proportion of ODS-positive patients was the highest when FP was used (30.6%) and the lowest when OCT was used (8.1%), and this difference was statistically significant (). There was no significant difference in the proportion of SRD-positive patients when the three fundus imaging methods were used to determine SRD (). The proportion of MT-positive patients was the lowest when FP was used (14.5%) and the highest when OCT was used (40.3%), and this difference was statistically significant (). FP fundus photography; FFA fundus fluorescein angiography; OCT optical coherence tomography; ODS optic disc swelling; SRD serous retinal detachment; MT mixed type. The chi-square test was used for comparison of variables. An intergroup difference is present when .
