CLOSE protocol

From OCT morphology to surgical decision-making.

The site introduces the CLOSE logic: minimum linear diameter, edge configuration, technique selection and anatomical follow-up.

01

Classify

Record MLD, base diameter, edge behavior and associated OCT features in a consistent format.

02

Treat

Connect morphology to technique families such as ILM peeling, flap strategies, ARG and hAM.

03

Follow

Track 30, 90, 180 and 360-day outcomes with OCT upload support and completion status.

Access

Public site, private app

Interested physicians register here. Approved participants receive the separate Registry app link by email.

Review

Masked OCT assessment

The Registry app keeps masked review and clinical workflows behind restricted access, separate from this public website.

Governance

Privacy-aware by design

The public site stores access requests in a separate database. The Registry app uses its own protected clinical database.
