Ophthalmology referrals from optometry: a comparative study (the R.O.C.S study).

VA and IOP measurements by optometrists are reliable, although IOP measurements were included less frequently in optometrist referrals. Optometrist referrals correctly localized eye pathology in 60.0% of cases. Two cases of retinal tear and 2 cases of retinal detachment, for which a precise reason for referral is ideal, were referred for other reasons.
