Background
We examined B-mode and en face images of swept-source optical coherence tomography (SS-OCT) from patients with central retinal artery occlusion (CRAO), and investigated associations between their characteristics and prognosis for visual acuity.
Methods
We retrospectively investigated 11 eyes in 11 patients with CRAO who underwent swept-source OCTA (PLEX Elite 9000®; Carl Zeiss, Dublin, California, USA) and SS-OCT (DRI OCT-1 Atlantis, Topcon, Tokyo, Japan) at the acute phase and 1 month after onset.
Results
Fern-like hyporeflective patterns aligned with the superficial arterioles were observed in acute-phase deep-layer en face images from 4 patients. Patients who exhibited these hyporeflective fern-like patterns were categorized as Group A, and all other patients as Group B. No significant difference in best-corrected visual acuity at initial examination was seen between the groups. At one month after onset, best-corrected visual acuity was significantly better in Group A, and retinal thinning also tended to be milder.
Conclusions
Our results indicate that a hyporeflective fern-like pattern in acute CRAO may suggest good prognosis.
