“…cases of "incomplete", "subtotal" and "total" CRAO combined) was 39 out of 178 eyes (or 22%) (Schmidt et al, 2002). Similarly, in the series presented by Ahn et al (2015), 34 out of 134 eyes (or 25%) with non-arteritic CRAO were categorised as "incomplete" CRAO, and this was the only category to show significant visual recovery after LIF (Ahn et al, 2015). This was also the experience of Schmidt and Schumacher (1998) but, as earlier indicated, substantial visual improvement is equally characteristic of eyes with "partial" CRAO and no therapeutic intervention .…”

“…However, what was described as "slight macular oedema" had an appearance indistinguishable from Grade 2 hypoperfusion maculopathy. Likewise, the exemplar fundoscopic and OCT pictures from the series presented by Ahn et al (2015) indicate that "incomplete" CRAO is associated with hypoperfusion maculopathy (either Grade 1 or Grade 2).…”

“…Of note, prolonged preparedness for prompt visual recovery after CRA recanalisation is indicated by the rapid functional improvement that is experienced by some patients during LIF procedures (i.e. within a few minutes of fibrinolytic injection) (Schmidt and Schumacher, 1998;Schumacher et al, 2010;Ahn et al, 2015). However, significant visual recovery isn't compatible with anoxic depolarisation of several hours' duration, even taking possible ischaemic preconditioning into account.…”

“…In many of the remaining 50% of eyes, an island or islands of peripheral visual field are preserved, especially on the temporal side (Hayreh and Zimmerman, 2005;Hayreh, 2011). Once vision is reduced to hand motion or less prior to retinal reperfusion, however, functional improvement after CRA recanalisation is extremely unusual (Augsberger and Magargal, 1980;Brown and Magargal, 1982;Ahn et al, 2015).…”

Objectives: This study was designed to examine effects of fundus fluorescein angiography (FFA) and indocyanine green angiography (ICGA) procedures on retinal and choroidal anatomy using optical coherence topography (OCT). Methods: Sixty eyes of 60 patients were included in this study. Patients who underwent FFA (14 females and 16 males) formed Group 1, and patients who underwent ICGA (17 females, 13 males) formed Group 2. After full ophthalmological examination, macular and choroidal thickness (CT) were measured via OCT. Approximately 15 to 20 minutes after dye was injected for angiography procedure, OCT scan was performed again. Statistical analyses were performed to compare measurements taken before and after procedure. Results: Mean age was 58.9±10.7 years (range: 42-82 years) in FFA group and 54.9±16.1 (range: 27-77 years) in ICGA group. Mean macular thickness was 339±78 μm before FFA and 339±72 after FFA (p=0.792). Mean macular thickness was 340±80 μm before ICGA and 341±73 μm after ICGA (p=0.571). Mean subfoveal CT was 275±36 μm before FFA and 271±31 μm after FFA (p=0.389). Mean subfoveal CT was 338±36 μm before ICGA and 366±38 μm after ICGA (p=0.022). There was significant increase in CT after ICGA procedure. Conclusion: CT may not change with FFA procedure, but may increase with ICGA procedure.

Background To evaluate the ability of optical coherence tomography angiography (OCTA) to quantitatively assess the effectiveness of intra‐arterial thrombolysis (IAT) surgery for the treatment of retinal artery occlusion (RAO). Methods This was a prospective observational study. Patients diagnosed with RAO who received IAT were enrolled. All participants underwent comprehensive ophthalmologic examinations and OCTA scans. The best‐corrected visual acuity (BCVA), vascular densities (VDs) of the superficial capillary plexus (SCP), deep capillary plexus (DCP), radial peripapillary capillaries, and central retinal thickness (CRT) were recorded. The above parameters were compared between RAO eyes and the fellow healthy eyes before and after IAT. Correlations between the BCVA and OCTA parameters in RAO eyes were calculated. Results Thirty‐four eyes from 34 consecutive RAO patients with a mean age of 51.0 ± 12.9 years were enrolled. There was a considerable decrease of VDs in the SCP, DCP, and radial peripapillary capillaries in all RAO eyes (all p < 0.001). Compared with contralateral normal eyes, CRT was significantly increased in RAO eyes (p < 0.001). The SCP and DCP VDs were significantly improved after IAT surgery (p = 0.010 and 0.014, respectively). BCVA in logMAR unit was negatively correlated with the DCP VD (r = −0.664, p = 0.010) and positively correlated with CRT (r = 0.597, p = 0.024) after surgery, but not significantly correlated with VDs or CRT before surgery. Conclusion Macular and peripapillary VDs of the retina detected by OCTA were greatly decreased in RAO eyes and improved after IAT treatment. OCTA is capable of quantifying VDs in separate retinal layers non‐invasively, conveniently, efficiently, and precisely.
