Figure 1 Clinical findings in patient 1. A: The cornea exhibited edema with local epithelial defect; B: The left eye was aphakic, and a prominent retinal detachment was visible through the pupil; C: A fundus examination revealed retinal detachment with choroidal detachment; D: Postoperatively, the retinal and choroidal detachment was completely reduced.

A: An examination showed a deep anterior chamber with blood and cells, iridocoloboma, aphakia, capsule remnants, and a massive vitreous hemorrhage; B: A color ultrasound showed choroidal detachment; C: The day after PPV, a globular elevation of the choroidal detachment was clearly visible in the temporal quadrant; D: At 1 year later, the fundus was flat without any signs of choroidal detachment.

Figure 3 Clinical findings in patient 3. A, B: An ultrasound showed choroidal detachment; C: A fundus examination revealed prominent choroidal detachment in four quadrants; D: Complete drainage of the suprachoroidal hemorrhage and flat retina was observed after vitrectomy was finished.

Figure 4 Clinical findings in patient 4. A: An ultrasound showed massive suprachoroidal hemorrhage with choroidal detachment; B: The choroidal detachment was completely reduced after surgery.
