Comparison of the study by Hayreh and Zimmerman3 and our study in terms of CRAO patients with a visual acuity of counting fingers or worse
| Study | Study design | No of patients | Mean age (years) | Treatment | BCVA on referral (logMAR) | Final VA (logMAR) | % of patients with BCVA improvement ≥0.3 logMAR |
| Hayreh and Zimmerman, 20053 | Prosp. Non-Comp. | 58 | 67.7 | Observation | ≤+1.7 | NA | 22 |
| Current study | Prosp. Non-Comp. | 17 | 70.1 | HBOT | +2.1 (mean) | +1.6 (mean) | 58.8 |
BCVA, best-corrected visual acuity; Comp, comparative; CRAO, central retinal artery occlusion; HBOT, hyperbaric oxygen therapy; logMAR, Logarithm of the Minimum Angle of Resolution; NA, not applicable; Prosp, prospective.
