At the end of follow-up, it was observed a higher frequency of inner nuclear layer cysts in patients with higher glycated haemoglobin ( p\u2009=\u20090.028). <\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p> This study showed the value and importance of OCT parameters, such as absence of INLc, as a prognostic therapeutic response. A normalization of the macular anatomy with ranibizumab is more likely to happen in early complete responders. The association between INLc and higher glycated haemoglobin levels showed the importance of systemic metabolic control in systemic diabetic manifestations.
