Study Arms:
- Ranibizumab 0.5 mg (Type: EXPERIMENTAL): Ranibizumab 0.5 mg was administered monthly by intravitreal injection in the study eye for 3 months. After the third injection, treatment was suspended if either one of the following criteria was met:~Improvement in best corrected visual acuity (BCVA) could not be attributed to treatment at the last 2 visits, in the opinion of the investigator, or BCVA \> 84 letters (approximate Snellen equivalent of 20/20) was observed at the last 2 last visits.~Patients also received sham laser treatment on Day 1 and subsequently at intervals of at least 3 months, if deemed necessary by the evaluating physician.~Active/sham laser treatment was always administered before (sham) intravitreal injections. The minimum interval between the 2 treatments was 30 minutes.~In the extension study at the investigator's discretion, patients received open-label ranibizumab 0.5 mg intravitreal injections once a month until stable vision was reached (a maximum of 24 injections) and could receive laser therapy.
- Ranibizumab 0.5 mg + laser (Type: EXPERIMENTAL): Ranibizumab 0.5 mg was administered monthly by intravitreal injection in the study eye for 3 months. After the third injection, treatment was suspended if either one of the following criteria was met:~Improvement in best corrected visual acuity (BCVA) could not be attributed to treatment at the last 2 visits, in the opinion of the investigator, or BCVA \> 84 letters (approximate Snellen equivalent of 20/20) was observed at the last 2 last visits.~Patients also received active laser treatment on Day 1 and subsequently at intervals of at least 3 months, if deemed necessary by the evaluating physician.~Active/sham laser treatment was always administered before (sham) intravitreal injections. The minimum interval between the 2 treatments was 30 minutes.~In the extension study at the investigator's discretion, patients received open-label ranibizumab 0.5 mg intravitreal injections once a month until stable vision was reached (a maximum of 24 injections) and could receive laser therapy.
- Laser (Type: ACTIVE_COMPARATOR): Laser photocoagulation treatment was administered on Day 1 and at intervals of at least 3 months, if deemed necessary by the physician. Patients also received monthly sham intravitreal injection in the study eye for 3 consecutive months. After the third injection, treatment was suspended if either one of the following criteria was met:~Improvement in best corrected visual acuity (BCVA) could not be attributed to treatment at the last 2 visits, in the opinion of the investigator, or BCVA \> 84 letters (approximate Snellen equivalent of 20/20) was observed at the last 2 last visits.~Active/sham laser treatment was always administered before (sham) intravitreal injections. The minimum interval between the 2 treatments was 30 minutes.~In the extension study at the investigator's discretion, patients received open-label ranibizumab 0.5 mg intravitreal injections once a month until stable vision was reached (a maximum of 24 injections) and could receive laser therapy.
