Claim 12:
13. The apparatus according to claim 5, wherein:
the receiver module is configured to receive a sequence of B-scans, which has been generated by the OCT imaging device repeatedly scanning the scanned region of the retina over the time period, as the OCT image data;
the apparatus further comprises a B-scan processing module configured o segment each B-scan in the sequence of B-scans into a plurality of B-scan layers so that each B-scan layer comprises respective sections of the A-scans forming the B-scan, and concatenate corresponding B-scan layers from the segmented B-scans to generate sequences of concatenated B-scan layers;
the correlation calculator module is configured to calculate, for each of at least one sequence of concatenated B-scan layers of the sequences of concatenated B-scan layers, a respective rolling window correlation between the sequence of concatenated B-scan layers and the sequence of stimulus indicators by calculating, for each stimulus indicator in the sequence of stimulus indicators, a correlation between
stimulus indicators in the window comprising the stimulus indicator and the predetermined number of adjacent stimulus indicators, and
B-scan layers of the B-scan layers that are based on B-scans which have been generated by the OCT imaging device while the retina was being stimulated in accordance with the stimulus indicators in the window; and
the response generator module is configured to generate the indication of the response of the retina to the light stimulus by generating, for each of the at least one sequence of concatenated B-scan layers, an indication of a response of a layer of the retina corresponding to the sequence of concatenated B-scan layers to the light stimulus, by combining the calculated correlations.
