Bottom Line: All patients were followed for a minimum of 36 months.In the control group, visual acuity improved from 1.15+/-0.43 to 0.43+/-0.44 and to 0.43+/-0.39 at 12 and 36 months, respectively (p=0.015 at 12 months, at p=0.003 at 36 months).Considering the favorable natural course of BVO and the unproven effect of reperfusion on macular edema, surgical efficacy of arteriovenous adventitial sheathotomy requires further evaluation.

ABSTRACT

Purpose: To evaluate long-term visual outcome of arteriovenous adventitial sheathotomy in BRVO-induced macular edema.

Methods: The visual outcomes of 8 patients following vitrectomy with arteriovenous adventitial sheathotomy for BVO-induced macular edema (surgery group) were retrospectively evaluated. The three-year post-operative visual acuity of the surgery group was compared with that of the conservatively managed controls.

Results: All patients were followed for a minimum of 36 months. Mean BCVA (logMAR) in the surgery group changed from 1.10+/-0.34 to 1.19+/-0.70 and to 0.80+/-0.36 at 12 and 36 months, respectively (p=0.959 at 12 months, p=0.018 at 36 months). In the control group, visual acuity improved from 1.15+/-0.43 to 0.43+/-0.44 and to 0.43+/-0.39 at 12 and 36 months, respectively (p=0.015 at 12 months, at p=0.003 at 36 months). A strong trend toward better visual acuity at 12 months and final examination was observed for controls. (surgery vs. control group, p=0.052 at 12 months, p=0.066 at 36 months).

Conclusions: Considering the favorable natural course of BVO and the unproven effect of reperfusion on macular edema, surgical efficacy of arteriovenous adventitial sheathotomy requires further evaluation.

Figure 1: Change in visual acuity since the initial visit.*p-value: Comparison between two groups, p=0.052 at 12 months, p=0.066 at 36 months.

Mentions: In the control group, visual acuity improved from 1.15±0.43 to 0.43±0.44 and to 0.43±0.39 at 12 and 36 months, respectively (vs. initial vision, p=0.015 at 12 months, p=0.003 at 36 months). Comparison of the surgery and control groups was performed using the mean BCVA at initial, 12 month, and final examination, and visual acuity of 20/40 or better (Table 2). Both groups were statistically similar with respect to initial visual acuity (p=0.814). However, a strong trend toward better visual acuity with the control group at 12 month and final examination was observed (surgery vs. control group, p=0.052 at 12 months, p=0.066 at 36 months) (Fig. 1). Changes in visual acuity between the initial and 36 month examination was also greater in the control group, but was not statistically significant. (surgery vs. control group, 0.30±0.28 vs. 0.72±0.47, p=0.053). At final examination, 62.5% of controls had 20/40 or better, compared with 12.5% in the surgery group (p=0.018).
