| Outcomes of treatments evaluated in this study | Cryo-therapy (n = 15) | Plaque (n = 4) | Chemotherapy (n = 11) | LSRT (n = 40) | WERT (n = 31) | Xenon+cryotherapy (n = 1) | CTT (n = 1) | Plaque+cryotherapy (n = 1) | Chemotherapy+WERT (n = 3) |
|---|---|---|---|---|---|---|---|---|---|
| LSRT = lens sparing radiotherapy, WERT = whole eye radiotherapy, Plaque = plaque brachytherapy, Xenon+cryotherapy = combined indirect xenon arc photocoagulation and cryotherapy, CTT = chemothermotherapy. | |||||||||
