Patients were divided into two groups: 892 eyes without diabetes and 204 eyes with diabetes. Best\u2010corrected visual acuity (BCVA), central retinal thickness (CRT) and presence of intraretinal fluid (IRF), subretinal fluid (SRF), subretinal hyperreflective material (SHRM) and atrophy were assessed at baseline, post\u2010loading phase and at 12\u2010month follow\u2010up.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>At baseline, no significant differences were observed between groups. Post\u2010loading phase, both groups showed significant improvements in BCVA and reductions in CRT. However, SRF persistence was notably more frequent in the diabetic group (64.2% vs. 27.2%, <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001). At 12\u2009months, SRF was present in 53.7% of the diabetic group compared to 34.9% of the non\u2010diabetic group (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001).
