Imaging features of optical coherence tomography angiography in paracentral acute middle maculopathy
Journal Title: Eye Science (Yanke Xuebao) - Year 2020, Vol 35, Issue 3
Abstract
[Objective:] To observe and summarize the imaging features of optical coherence tomography angiography (OCTA) in paracentral acute middle maculopathy (PAMM). [Methods:] A total of 25 patients (26 eyes) were diagnosed with PAMM in this retrospective study, including 15 male (16 eyes) and 10 female (10 eyes). All patients underwent the best corrected visual acuity (BCVA), fundus photography, spectral-domain optical coherence tomography (SD-OCT), fundus auto fluorescence (FAF), visual field examination, multifocal electroretinograms (M-ERG) and OCTA examinations. Ten patients underwent fundus fluorescein angiography (FFA) and indocyanine green angiography (ICGA) examination. [Results:] OCTA showed the vessel flow density in the superficial capillary plexuses (SCP) and deep capillary plexuses (DCP) were decreased significantly. By adjusting the stratification line to the intermediate capillary layer inner plexiform layer (IPL)-10 to IPL+30, En face image showed the fern-like hype-reflection distribution around the vein. B-scan showed the discontinuous hyper-reflection bands in the inner nuclear layer (INL) and outer plexiform layer (OPL). [Conclusion:] PAMM lesions are mainly located in the intermediate capillary plexuses (ICP), OCTA can show the form and structure of lesions clearly, which has the characteristic image in En face and B-scan model. Compared with the other traditional examinations, OCTA has the advantage of stratified observation of PAMM lesions.
