Modified posterior drainage of post-operative suprachoroidal hemorrhage

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.
