Arm Intervention/treatment
Experimental: Arm A
Participants will receive 4 low-dose RO7200220 intravitreal (IVT) injections every 4 weeks (Q4W) to Week 12, followed by as-needed (PRN) dosing from Week 20 to Week 48.
 Drug: RO7200220
Participants will receive RO7200220 IVT injection
Experimental: Arm B
Participants will receive 4 high-dose RO7200220 IVT injections Q4W to Week 12, followed by PRN dosing from Week 20 to Week 48.
 Drug: RO7200220
Participants will receive RO7200220 IVT injection
Sham Comparator: Arm C
Participants will receive 4 sham injections Q4W to Week 12, followed by PRN sham dosing from Week 20 to Week 48.
 Other: Sham
Participants will receive a sham procedure that mimics an IVT injection.
