One study6 was observer masked and patients randomly selected from community optometrist referrals but only one consultant ophthalmologist and one trainee general ophthalmologist participated in the study. The other study8 was observer masked but it was not clear whether the patients were recruited in a randomised or consecutive fashion. Only one general ophthalmologist (research fellow) and one senior optometrist participated in the study and confidence intervals for the kappa statistic were not reported.
