| Brodovsky SC et al, 2000, Australia | 121 patients with 177 alkali burnt eyes over 11 years. | Retrospective clinical comparison | Time to re-epithelialisation | Delay in grade 2 burns. Trend for longer in 1, shorter in 3 and no difference in 4 | Uncontrolled. Very few conservatively treated patients |
| Standard alkali protocol (antibiotics, intensive topical corticosteroids, ascorbate, citrate and antibiotics) v conservative protocal (antibiotics, short course of corticosteroids) | | Final visual acuity | Better in grade 3 burns. No difference in 1, 2, and 4 | Conclude that ascorbate and citrate are the effective agent for grade 3 burns without considering the effect of intensive corticosteroid alone |
