How quickly does visual acuity recover after Macular Hole surgery?

What is it about?

We examined the rate of acuity recovery in a group of macular hole patients. We followed these participants for at least 6 months and measured changes in their vision using different acuity measures. The results indicted that most of the recovery occurs within the first 3-6 months.

Why is it important?

This information can be used to counsel patients that have to decide whether to undergo this treatment, and can give them a better understanding of the recovery process and the expectations they can have in terms of their recovery process.

Perspectives

This study was the central part of my Master's thesis in experimental psychology and was inspired by a macular hole patient who demonstrated an interesting pattern of recovery and acuity improvement, even over a period of 2 years. I am still speculating whether part of her recovery was more about cortical adjustment and functional compensation mechanisms.
