Introduction. Ischemic maculopathy is the main cause of irreversible vision loss due to retinal vein occlusion (RVO). Fluorescent angiography (FA), being “golden standard” in evaluating retinal capillary plexus does not allow to visualize separately intraretinal capillary networks. Optical coherence tomography angiography (OCT-angiography) gives the possibility to visualize 4 capillary plexi and allows carrying out a quantitative analysis of microcirculation quantitatively estimating capillary network density and non-perfusion areas. Aim: to investigate microcirculation changes using OCT-angiography data and to compare them to opthalmoplethysmography indices in patients with RVO. Material and methods: The study included 12 patients with retinal vein occlusion. In all patients, routine ophthalmic examination was carried out, and additionally ocular blood flow was estimated using FA, OCT-angiography and ophthalmoplethysmography. Results: Ischemia in the macular area was detected in 4 patients (25%) according to FA results, and in 8 (67%) according to OCT-angiography data. In comparison with the unaffected eye, significant decrease in density of both superficial and deep capillary plexi, decrease in ‘flow area’ and enlargement of foveal avascular zone were observed. Significant close direct correlation was established between capillary density in the superficial capillary plexus (r > 0.8) and the deep one (r > 0.7), choroidal thickness, and opthalmoplethysmography indices (r > 0.6). Conclusion: When compared to FA, OCT-angiography is a more sensitive method to detect macular capillary perfusion. In case of retinal veins occlusion the combination of the above mentioned methods with ophthalmoplethysmography allows to perform comprehensive evaluation of the regional hemodynamics.

Abstract Background To compare changes in retinal microvasculature of young and elderly patients with retinal vein occlusion (RVO) after anti-VEGF treatment. Methods RVO patients who underwent anti-VEGF treatment were retrospectively reviewed and categorized into two groups based on age. The OCT angiography images were obtained during each visit. Best corrected visual acuity (BCVA), vessel density (VD) and foveal avascular zone (FAZ) were measured and compared between the two groups. Vision improvements and retinal microvasculature changes were also correlated. Results Twenty patients with 20 eyes were enrolled in the younger group and 46 patients with 46 eyes were enrolled in the older group. Younger patients demonstrated better BCVA, higher VD and smaller FAZ than older patients at 12 months after the first anti-VEGF treatment. The improvement of VD was observed only in the younger group. A positive correlation between vision improvement and VD increase was noted. Conclusions Young patients with RVO can achieve rapid rehabilitation of deep retinal vasculature which lead to a better visual outcome.

Abstract Purpose: To evaluate the correlation between changes of the macular capillary network and macular edema (ME) recurrence in branch retinal vein occlusion (BRVO) using swept-source optical coherence tomography (SS-OCT) angiography. Methods: We reviewed the data of 43 patients with treatment-näive ME associated with BRVO. Patients who received intravitreal bevacuzumab injection were divided into two groups based on ME recurrence after 6 months after edema resolution. The perifoveal capillary morphology and the macular capillary vessel density (VD) were retrospectively analyzed with en face SS-OCT angiography image after ME resolution. Results: In the ME recurrence group (n=22), a broken the perifoveal capillary ring in the superficial capillary plexus (SCP) and deep capillary plexus (DCP) was more common than the no ME recurrence group (p = 0.047 and p = 0.002). The destruction of the perifoveal capillary ring of the DCP (30.0° vs 87.3°, p = 0.001) was more severe than that of the SCP (17.3° vs 69.5°, p = 0.006) in the ME recurrence group compared with the no ME recurrence group. The hemi-VD disparity between the affected areas and the unaffected areas in the SCP and DCP showed significant differences (p = 0.031 and p = 0.017), while macular VD showed no differences between the groups. Conclusions: The destroyed perifoveal capillary ring and the hemi-VD disparity were related to the recurrence of ME in BRVO. Therefore, these factors can be helpful in predicting ME recurrence.
