摘要

Purpose: To evaluate the efficacy of intravitreal gas (perfluoropropane, C3F8)-assisted displacement of submacular hemorrhage (SMH) secondary to recent or old blunt trauma.Methods: An interventional case series of three patients who presented with SMH after blunt trauma, ranging from 2 days to 2 weeks back. All three patients were treated with an intravitreal injection of 0.3 cc of 100% C3F8 with anterior chamber paracentesis. Strict prone position was advised for 2 weeks with a minimum of 6 to 8 hours per day. Documentation was done with serial recording of corrected distance visual acuity, fundus photographs, and spectral domain optical coherence tomography both before and after intervention.Results: The follow-up period ranged from 2 weeks to 3 months. All patients showed a significant displacement of SMH with recovery of the normal foveal contour; foveal thinning was noted in 2 cases. Best spectacle-corrected visual acuity improved from counting finger at 1 m to 20/30 in Case 1 and counting finger 3 m to 20/40 in Case 2. In Case 3, the visual acuity remained unchanged from the preoperative 20/60 which could be attributed to the presence of a choroidal rupture in the foveal area that became evident after the displacement of SMH.Conclusion: Pneumatic displacement is an effective technique in the management of SMH due to recent or old blunt trauma.
