- Impending hole (top left picture) designated as either stage 1a or stage 1b:
- Yellow foveal spot
- Yellow ring surrounding fovea
- Small full thickness hole. Fovea has lost its depression on OCT as the vitreous is pulling up the fovea. This is vitreomacular traction.
- Full thickness hole with the vitreous still attached, possibly creating an operculum/flap visible on OCT. Positive Watzke-Allen sign.
- Full thickness hole with PVD
