1- Experienced operator required for quantitative data acquisition.
2-Signal strength may impact nerve fiber layer thickness measurement..
3-RNFL detection algorithm may fed.
4-Ability to detect change needs validation.
5-Often requires papillary dilation to achieve optimal image quality.

For cooperative patients the test can be completed in a few minutes.

As per doctors advise.
