This difference remained significant when considering subgroups with unifocal or multifocal GA lesions , because eyes with ORT in both subgroups had a slower enlargement amount of GA than eyes without ORT ( @ vs. @ -LSB- P = @ -RSB- , in eyes with multifocal GA lesions ; and @ vs. @ -LSB- P = @ -RSB- , in eyes with unifocal GA lesions ) .
