Stryewski et al developed the RD-OGI (retinal detachment after open globe injury) score to predict retinal detachment after an open globe injury. The authors are from the Massachusetts Eye and Ear Infirmary at Harvard Medical School.
Patient selection: open globe injury (OGI)
Outcome: retinal detachment (RD)
Parameters:
(1) visual acuity
(2) highest zone of injury
(3) vitreous hemorrhage

= SUM(points for all 3 parameters)
Interpretation:
• minimum score: 0
• maximum score: 7.5
• The higher the score the greater the risk of retinal detachment.
