Outcome of referrals by optometrists to general practitioners: an 18 month study in one practice.

All general ophthalmic services forms (GOS18) received by one practice over an 18 month period were analysed and the patient outcome after two years noted from the practice records. Sixty one forms were collected. Fifty patients (82%) were referred by the general practitioners to the local eye hospital. Among the 45 patients that have so far been seen by an ophthalmologist, 22 (49%) were diagnosed as having cataracts, eight (18%) macular degeneration and two (4%) glaucoma. Thirteen patients (29%) were found to have normal eyes. Nine of the 61 patients (15%) were not referred to an ophthalmologist and two patients (3%) were already under review at the eye hospital. It is concluded that some referrals to ophthalmologists might be avoided if general practitioners received improved training in ophthalmology, However, general practitioners remain an effective filter in the referral system between optometrists and ophthalmologists.
