Modified posterior drainage of post-operative suprachoroidal hemorrhage

Abstract

Purpose: To study the anatomical and functional outcomes of trans-conjunctival 23G or 25G cannula-guided modified posterior passive drainage of post-operative suprachoroidal hemorrhage (SCH). Methods: A retrospective study was done on 15 eyes in the last nine years. Vitrectomy with perfluorocarbon liquid injection to push SCH from inside along with 23G or 25G cannula-guided passive drainage of SCH was performed by making multiple sutureless posterior sclerotomies at 10–15 mm behind the limbus. Postoperatively, best corrected visual acuity (BCVA), intraocular pressure (IOP), and posterior segment findings were compared from pre-operative findings. Results: Mean age at presentation was 64.93 ± 7.62 years. Complete resolution of SCH with attached retina was achieved in 60% (9/15) of cases. Mean pre-operative BCVA of Log MAR 2.82 ± 0.21 improved to mean post-operative BCVA Log MAR 1.04 ± 0.53 (P < 0.001). Mean pre-operative IOP of 27.87 ± 8.67 mmHg improved significantly to post-operative IOP of 10.2 ± 5.16 mmHg (P < 0.001). Silicone oil removal was possible in 11/15 (73.33%) cases. Conclusion: Posterior passive drainage of post-operative SCH by multiple sclerotomies using 23G or 25G cannulas can salvage these eyes with both anatomical and functional recovery.
