* The eligibility criteria for the trial required patients to have a best corrected visual acuity of between 20/40 (70 letters) and 20/320 (25 letters). † Data from the three treatment arms were pooled. ‡ Half the patients in this visual acuity group were assigned to the 60 letter state in the Model and half were assigned to the 45 letter state. |
