    Abstract:
    PURPOSE: To investigate the effectiveness of displacement of submacular hemorrhage (SMH) caused by polypoidal choroidal vasculopathy (PCV) by assessing retinal sensitivity using microperimetry. METHODS: We retrospectively reviewed the medical records of 11 consecutive PCV patients with SMH. All patients underwent vitrectomy, subretinal injection of tissue plasminogen activator, and fluid-air exchange, followed by antivascular endothelial growth factor therapy using a pro re nata regimen. The retinal sensitivity was measured by use of microperimetry before and after surgery. RESULTS: The mean (SD) age of the patients was 74.1 ± 9.4 years. The mean SMH diameter was 6.8 ± 5.2 disc diameters. The best-corrected visual acuity (BCVA), mean retinal sensitivity, and mean number of measure points with a sensitivity ≥10 dB before the surgery were 0.94 ± 0.49, 4.2 ± 4.5 dB, and 15.6 ± 15.1 points, respectively. These had significantly improved 6 months after surgery (0.39 ± 0.37, 15.6 ± 7.3 dB, and 50.9 ± 22.2 points, respectively; P < 0.05 for all outcome measures). The mean number of measure points with an absolute scotoma before surgery had decreased significantly 6 months after surgery (from 40.5 ± 15.0 to 9.4 ± 16.0 points; P < 0.001). CONCLUSIONS: Displacement of SMH effectively improves retinal sensitivity as well as BCVA.
