Vitreous surgery simulator.

OBJECTIVE To reduce the surgical risks to patients and expose surgeons to surgical experience and complications, we have developed a practical system of vitreous surgery using virtual-reality technology. METHODS The system is composed of high-resolution color stereo binoculars, haptic devices, foot switches, and a high-speed graphics computer. To simulate vitreous surgery, we created several ...

Surgical results and visual outcomes of vitreous surgery for advanced stages of retinopathy of prematurity.

PURPOSE We evaluated the effectiveness of vitreous surgery for advanced stages of retinopathy of prematurity (ROP) with traction retinal detachment. METHODS Vitreous surgery was performed in 34 children (51 eyes) with total traction retinal detachment associated with stage 5 ROP between January 1989 and December 1991 at the Fukuoka University Hospital. The first phase of the procedure was com...

The percentage of vitreous prolapse varies with different ophthalmic surgeons.
