What is it about?

Traditionally, the outcome of macular hole surgery is evaluated by changes in visual acuity whereby patients read black letters on a white eye-chart. This study compared several ways of measuring vision in patients that had undergone macular hole surgery, and explored ways in which to quantify visual distortions that are sometimes a part of the recovery period.

Why is it important?

Measuring vision with black letters on a white background is not really representative of visual tasks and experiences in every-day life. Therefore, we continue to explore other ways of measuring visual ability that are clinically meaningful and that are informative for both the patient and their eye-care provider.


This study was the first in a series of six studies in our lab that examined visual recovery after macular hole surgery. I found it specifically enlightening in my efforts in bringing together basic psychophysics and visual clinical science, as the perspectives and priorities are not always similar or compatible; however, slowly, we succeed in bringing basic and clinical science closer together and to let both earn from each other.
