Introduction: To evaluate the sensitivity and specificity of optical coherence tomography angiography (OCTA) in comparison to fluorescein angiography (FA) in discerning between macular hemorrhages due to myopic macular neovascularization (m-MNV) and idiopathic macular hemorrhage (IMH) in patients with high myopia (HM). Methods: In this retrospective study, 14 eyes of 14 patients (mean age 60 ± 16 years) affected by macular hemorrhage due to HM were included. All patients underwent OCTA and FA at the time of macular hemorrhage (i.e., baseline) and were followed for a 3-month follow-up. Results: By means of FA, 8 out of 14 eyes with macular hemorrhage (57%) were diagnosed as type 2 m-MNV, whereas 6 eyes (43%) were diagnosed as IMH. Interestingly, OCTA displayed the presence of a neovascular network in all cases previously diagnosed as m-MNV using FA, and also excluded the presence of anomalous flow in all IMH eyes. This accounted for the high sensitivity and specificity of OCTA for m-MNV detection in HM cases with macular hemorrhage. After 3-month follow-up, BCVA improved from 0.39 ± 0.15 to 0.21 ± 0.14 logMAR (p = 0.006) in patients with m-MNV treated by a mean of 2.3 ± 0.9 intravitreal anti-VEGF injections. Conversely, BCVA improved without treatment (from 0.55 ± 0.48 to 0.17 ± 0.08 logMAR, p = 0.112) in patients with IMH. Conclusions: OCTA is able to differentiate with excellent reliability between the presence of m-MNV in patients with HM presenting with a new macular hemorrhage and an IMH. This could be of paramount relevance in the clinical setting for the diagnosis and treatment of patients with HM.

Abstract

Introduction: To evaluate the sensitivity and specificity of optical coherence tomography angiography (OCTA) in comparison to fluorescein angiography (FA) in discerning between macular hemorrhages due to myopic macular neovascularization (m-MNV) and idiopathic macular hemorrhage (IMH) in patients with high myopia (HM). Methods: In this retrospective study, 14 eyes of 14 patients (mean age 60 ± 16 years) affected by macular hemorrhage due to HM were included. All patients underwent OCTA and FA at the time of macular hemorrhage (i.e., baseline) and were followed for a 3-month follow-up. Results: By means of FA, 8 out of 14 eyes with macular hemorrhage (57%) were diagnosed as type 2 m-MNV, whereas 6 eyes (43%) were diagnosed as IMH. Interestingly, OCTA displayed the presence of a neovascular network in all cases previously diagnosed as m-MNV using FA, and also excluded the presence of anomalous flow in all IMH eyes. This accounted for the high sensitivity and specificity of OCTA for m-MNV detection in HM cases with macular hemorrhage. After 3-month follow-up, BCVA improved from 0.39 ± 0.15 to 0.21 ± 0.14 logMAR (p = 0.006) in patients with m-MNV treated by a mean of 2.3 ± 0.9 intravitreal anti-VEGF injections. Conversely, BCVA improved without treatment (from 0.55 ± 0.48 to 0.17 ± 0.08 logMAR, p = 0.112) in patients with IMH. Conclusions: OCTA is able to differentiate with excellent reliability between the presence of m-MNV in patients with HM presenting with a new macular hemorrhage and an IMH. This could be of paramount relevance in the clinical setting for the diagnosis and treatment of patients with HM.
