Eligibility criteria
Key Inclusion Criteria:
* Participant must have at least one study eye with a positive diagnosis of MacTel Type 2
* Participant must have an Inner Segment - Outer Segment Junction Line (IS/OS) Photo Receptor (PR) break in the study eye(s) and en face EZ (area of IS/OS loss) as measured by spectral-domain optical coherence tomography (SDOCT) between 0.16 mm\^2 and 2.00 mm\^2

Key Exclusion Criteria:
* Participant received intravitreal steroid therapy for non-neovascular MacTel within the last 3 months
* Participant has ever received intravitreal anti-vascular endothelial growth factor (VEGF) therapy in the study eye or has, within the past 3 months, received intravitreal anti-VEGF in the fellow eye
* Participant has evidence of ocular disease other than MacTel that, in the judgment of the examining physician, may confound the diagnosis, procedures or outcome of the study
