Abstract

Purpose. To assess factors predicting final visual outcome after displacement of subretinal hemorrhage (SRH) by intravitreally injected tissue plasminogen activator (TPA) and gas in patients suffering from age-related macular degeneration (ARMD).

Methods. We evaluated retrospectively the records of 67 patients (32 men, 35 women, mean age 77.2 years) suffering from SRH caused by ARMD who underwent TPA and gas injection between April 1996 and October 2000. Visual acuity (VA; preoperative, 1 week and 3 months postoperative) was analyzed with respect to duration and dimension of bleeding (diameter and thickness) and patient’s age.

Results. Mean preoperative VA was 0.063, compared with 0.1 at 3 months after injection. Twenty-nine of 47 patients (76%) had an increase in VA 1 week after treatment but 14 of these eyes worsened slightly during follow-up. Visual outcome 3 months after therapy was negatively correlated to thickness (P<0.05) and diameter (P<0.001) of the SRH. In a statistical model of a multiple regression analysis, postoperative VA and the shift of VA could be predicted by preoperative VA and diameter of SRH. Patient’s age, duration and thickness of SRH had no prognostic value for postoperative visual outcome.

Conclusion. After SRH caused by ARMD, the best visual outcome after TPA + gas injection can be expected in patients with preoperative VA of less than 0.1 caused by a small SRH. In the presence of large SRH (diameter >5 mm) an increase in VA after therapy is unlikely.
