The IMPC analysis pipeline does not take into account whether an abnormality is fully penetrant or not and the same weight is given for an abnormal observations in one or both eyes. In cases where it is not possible to confirm if an abnormality is present or not, the data is not included in the statistical analysis. The following logic is applied in determining whether to include the data in analysis:\r\n<ul>\r\n<li>If at least one of the eyes shows an abnormality in a particular parameter, the data for that specimen will be included in the statistical analysis even if the other eye is marked as \"no data\".</li>\r\n<li>If the eyes are marked as \"no data\", or one eye is normal and the other eye is \"no data\" for a particular parameter the data for that specimen will not be included in the statistical analysis.</li>\r\n</ul>\r\n</li>\r\n</ul>\r\n<br />\r\n<p><strong>Data QC</strong></p>\r\n<p>Image QC is typically performed during data collection to ensure high quality images are captured whilst eyes are dilated etc.</p>"}
