Correlations between oct‐angiography and maia microperimetry in patients who have suffered a rhegmatogenous retinal detachment

Purpose: Describe the existing correlations between the OCT‐Angiography (OCTA) and the MAIA microperimetry in patients who have suffered a rhegmatogenous retinal detachment (RRD).Methods: We conducted a cross‐sectional study comparing 65 eyes that suffered primary RRD that was successfully repaired by PPV and SF6 with a control group consisting of 136 eyes. All underwent a comprehensive ophthalmologic examination, including OCTA and MAIA microperimetry.Results: There were no differences between the groups in terms of age, sex, laterality of the studied eye, or IOP.The correlations between OCTA and MAIA in the RRD group were as follows: The SCP: the S sector showed a positive correlation with the C (r = 0.314) and central‐superior (CS) (r = 0.339) sectors of the MAIA. The inferior (I) sector reached a negative correlation with the inferior‐outer (IO) (r = ‐0.298) and inferior‐inner (II) (r = ‐0.376) sectors of the MAIA. The N sector reached a positive correlation with the BCEA 63 angle (r = 0.306) while this correlation was negative with the C sector (r = ‐0.293) of the OCTA. The DCP: the C sector of the OCTA correlated with the temporal‐inner (TI) sector (r = 0.297) of the MAIA. The area of the FAZ correlates with sector II (r = ‐0.298) of the MAIA. C sector reached correlation with BCEA 63 angle (r = ‐0.464) and 95 angle (r = ‐0.482), the area of the FAZ correlated with the BCEA 95 angle (r = 0.290) and the vertical diameter of the FAZ with both BCEA 63 angle (r = 0.345) and 95 angle (r = 0.341). The CC: the S sector presented a positive correlation with the C (r = 0.409) and CS sectors (r = 0.333) of the MAIA. The BCEA area 63% (r = 0.290) and 95% (r = 0.292) of the MAIA correlated with the OCTA's. The BCEA angle 63% (r = 0.325) and 95% (r = 301) of the MAIA correlated with the OCTA T sector. Conclusions: While OCTA vertical sectors achieve correlations with macular sensitivity in vertical sectors quantified by MAIA microperimetry, horizontal sectors correlate with fixation parameters.
