 Success rates

	Superior breaks group (controls)	Inferior breaks group (patients)	Overall data from 279 RRD cases
Primary success rate	41/48 (85.4%)	39/48 (81.3%)	248/279 (88.9%)
Final success rate	46/48 (95.8%)	46/48 (95.8%)	272/279 (97.5%)

Primary success rates are similar in the superior and inferior breaks groups (p = 0.63).

The third column shows our overall performance for all primary RRDs at our unit (excluding PVR, giant tears, dialyses, and retinoschisis). The patients with inferior breaks represent a higher risk group when compared to our overall data.
