Statistical Errors in Ophthalmic Research

Biomedical statistics is essential part of any scientific study; a review of the current scientific literature indicates that statistical analysis is an area that frequently needs improvement. To address this, we put forward some of the most common errors in statistical analysis of ophthalmic data. In ophthalmic data generally when statistical tests are performed, the correlation generally present between observations made for the right and left eyes of a subject, is ignored or is not taken account for. The error leads in a consequence of over statement of the precision of the study that is resulting incorrect P values indicating a greater measure of statistical significance than the data warrant.
