Correction to the paper, “Peripheral areas of nonperfusion in treated central retinal vein occlusion as imaged by wide-field fluorescein angiography”

Dear Dr. Brucker,

While checking over old data I discovered an error in the paper, Spaide RF. Peripheral areas of nonperfusion in treated central retinal vein occlusion as imaged by wide-field fluorescein angiography. Retina. 2011 May;31(5):829-37. The square millimeters of non-perfusion were calculated correctly, but there was an error in converting these measurements to disc areas. To calculate the area of the retina, the real area of the optic disk had to be calculated. Unfortunately when converting the areas of non-perfusion to disk areas the real value for the disk area was used instead of the Macular Photocoagulation Study standard of using a circular diameter of 1500 microns. Thus the area measurements in Macular Photocoagulation Study disk areas when stated in manuscript were understated by a factor of 1.44. This conversion was made for only one set of measurements, which otherwise were stated in square millimeters. The statement, “the peripheral area of nonperfusion ranged from 16 disk areas to 242 disk areas” should have been, “the peripheral area of nonperfusion ranged from 23 disk areas to 348 disk areas”.

Sincerely

Richard F. Spaide
