Abstract
Purpose
To study the usefulness of multicolor imaging (MC) photographs in addition to near infrared reflectance (NIR) and spectral domain optical coherence tomography (SD-OCT) in the detection and follow up of acute macular neuroretinopathy (AMN).
Patients and methods
Six patients with a complaint of paracentral scotomas in at least one eye due to AMN were included. They underwent full ophthalmic examination and multimodal imaging including color fundus photographs, (SD-OCT), NIR, and MC at baseline and follow up.
Results
Four females and two males, aged 19–64 years, and eight eyes affected by AMN, were included. Acute phase SD-OCT in all patients confirmed the diagnosis of type 2 AMN with partial recovery of the outer retina in the convalescent phase. NIR and MC elicited in all cases hypo-reflective AMN lesions pointing toward the fovea. MC exhibited a higher contrast between the affected and the physiologic retina that slowly attenuated during the follow up showing a decrease in the hypo-reflectance of the lesions.
Conclusion
MC imaging was more detailed than fundus color photographs and as detailed as NIR in the detection of AMN. When available, MC imaging should complement SD-OCT and NIR in the diagnosis and follow up of this rare inflammatory condition that may be underdiagnosed.
