The Caliber of Optociliary Shunt Vessels Is Associated with Macular Blood Flow and Visual Acuity in Central Retinal Vein Occlusion
PURPOSE: To define the role of optociliary shunt vessels (OSVs) in eyes with central retinal vein occlusion (CRVO) using OCT angiography (OCTA) with macular parameters. DESIGN: Retrospective, observational, consecutive case series. PARTICIPANTS: Forty-one eyes in 38 consecutive patients with CRVO we...

description | PURPOSE: To define the role of optociliary shunt vessels (OSVs) in eyes with central retinal vein occlusion (CRVO) using OCT angiography (OCTA) with macular parameters. DESIGN: Retrospective, observational, consecutive case series. PARTICIPANTS: Forty-one eyes in 38 consecutive patients with CRVO were analyzed in this study. METHODS: Optic disc and macula were imaged by swept-source OCTA (3 × 3 mm) as well as by high-quality fundus photography. MAIN OUTCOME MEASURES: We compared macular vessel density (VD) and visual acuity between eyes in which OSVs developed and those in which they did not. Furthermore, we measured the diameter of the OSVs and analyzed the correlation with macular VD and visual acuity. RESULTS: Optociliary shunt vessels were found in 25 eyes (61%). Central retinal vein occlusion with OSVs did not show any statistical difference compared with CRVO without OSVs in either macular VD of the total retina (0.31 ± 0.07 and 0.26 ± 0.09, respectively; P = 0.0937) or final best-corrected visual acuity (BCVA) (0.30 ± 0.43 logarithm of the minimum angle of resolution [logMAR] and 0.59 ± 0.54 logMAR, respectively; P = 0.0705). The mean OSV diameter was 71 ± 30 μm in CRVO with OSV. The diameter of the OSVs was correlated positively with superficial VD (r = 0.443; P = 0.027), deep VD (r = 0.494; P = 0.012), and total VD (r = 0.491; P = 0.013). Furthermore, the OSV diameter was also negatively correlated with BCVA (logMAR) at the final visit (r = –0.531; P = 0.006). CONCLUSIONS: The results demonstrated that the diameter of the OSVs was associated with macular VD and visual acuity in patients with CRVO. The development of large OSVs on the optic disc may be a good indicator of the maintenance of blood flow in the macula. |
