both globes show asymmetric posterior bulging with irregular thinning of the sclera

From the case:
Posterior staphyloma
{"current_user":null,"step_through_annotations":true,"access":{"can_edit":false,"can_download":true,"can_toggle_annotations":true,"can_feature":false,"can_examine_pipeline_reports":false,"can_pin":false},"extraPropsURL":"/studies/87608/annotated_viewer_json?iframe=true\u0026lang=us"}
Key images demonstrating bilateral asymmetric globe bulge and scleral thinning.
Case Discussion
The main differential would be coloboma, but as the scleral thinning is predominantly temporal to the optic disc the findings rather represent posterior staphyloma.
