Since the publication of the above article, the authors have noticed that the first sentence within the Results section under the subheading ‘Fornix depth measurements’ is incorrect.

The sentence is shown below:

The mean vertical fornix depths measured from the upper nasal and temporal as well as the lower nasal and temporal fornices in the control eyes were 14.1±2.5, 14.1±2.5, 10.0±2.1, and 10.4±1.8 mm, respectively. The mean horizontal fornix depths in the control subjects measured 3.0±0.9 and 5.2±1.2 mm, respectively.

The authors would like to apologise for this mistake.
