Traumatic retinopathy presenting as acute macular neuroretinopathy

Aim: Traumatic retinopathy presenting as acute macular
neuroretinopathy (AMNR) is an uncommon disease causing paracentral
scotomas after indirect trauma. Methods: We report on five patients
(six eyes) with AMNR with a temporary reduction of visual acuity
and persistent paracentral scotomas after indirect trauma. The
findings were documented using multimodal imaging and the follow-up
was up to 32months. Results: Initially, fundoscopy was unremarkable
in all patients while visual acuity (Snellen equivalents) varied
between 0.03 and 1.0, and a paracentral scotoma was present in all
patients. During follow-up, visual acuity recovered to 1.0 in all
patients while the paracentral scotomas persisted. Spectral-domain
optical coherence tomography revealed a disruption of the
inner/outer segment junction within the macular lesion and changes
in the outer nuclear layer, which slowly recovered partly during
the follow-up. Conclusions: These findings suggest that indirect
trauma can cause changes in the outer retina resembling those seen
in AMNR, resulting in persisting paracentral scotomas.
