GDI: glaucoma drainage implant, NVD: optic disc neovascularization, NVG: neovascular glaucoma, PRP: pan-retinal photocoagulation, RP: retinal photocoagulation, ※ 1: Values in ( ) indicate IOP before the occurrence of neovascular glaucoma (NVG). Values in (,) indicate IOP of R & L eyes before the occurrence of NVG. ※ 2: Existence of ocular hypertension (OH) or primary open angle glaucoma (POAG) before occurrence of neovascular glaucoma. ※ 3: Neovascularization elsewhere (NVE) and optic disc neovascularization (NVD) before and after accomplishment of pan-retinal photocoagulation Number of NVE: 0=0, I=1-3, II=4> ※ 4: Period between the first RP or PRP and diagnosis of NVG ※ 5: Period between the diagnosis of neovascular glaucoma and achievement of PRP. ※ 6: +- indicates with or without topical anti-glaucoma medication. ※ 7: Glaucoma drainage surgery was performed for the left eye of Patient 9 within six months after the achievement of PRP
Table 2: Group I: Eyes which received retinal photocoagulation before the occurrence of neovascular glaucoma Twelve eyes of 9 patients. Grey line indicates the eyes that failed to achieve IOP control (21 or <21 mmHg) after achieving PRP
