RESUMO
BACKGROUND: Community-based optometry services are increasingly used as a primary resource for patients with acute eye problems. The Eye Health Examination Wales (EHEW) is an example of one such established scheme. The aim of the project was to show how the aforementioned pathway has affected the presentation of ocular conditions to a general emergency department and the eye casualty department at the same hospital. METHODS: Clinical data were collected prospectively over a one-month period. The records of 100 consecutive patients with ocular pathology presenting to a general emergency department were analysed. Numbers were also obtained for the number of patients seen under the EHEW scheme by community optometrists for the same period. The notes of patients referred to ophthalmology or back out to the community optometry scheme were followed to monitor for re-attendance in either setting. RESULTS: Eighty-five per cent of patients were walk-in cases. The most common diagnosis made in the emergency department was 'no abnormality found' in 37 per cent. Eighty per cent of all conditions were discharged from the emergency department. Fifteen per cent of all cases, mainly foreign body-related, were followed up in the emergency eye clinic and 10 per cent were sent to EHEW for follow-up. No cases re-presented to a hospital service at a later date. CONCLUSION: At least 37 per cent of emergency department cases could have been potentially avoided had the patient presented to the EHEW scheme. The pathway for patients to be sent from the emergency department to an EHEW optometrist does not appear to delay presentation to an ophthalmologist thereafter. Further promotion of the EHEW service is needed to change patient behaviours and reduce avoidable attendance to overstretched emergency departments.

We write to report a rare case of unilateral cancer-associated retinopathy previously undocumented in the literature. Cancer-associated retinopathy is an uncommon paraneoplastic syndrome. It is characterised by retinal antigen autoantibodies causing rod and cone dysfunction and abnormal electroretinography findings with consequent progressive visual loss.Our patient, known to have a primary cervical intraepithelial neoplasia, presented with unilateral blurred vision as well as a disturbance in colour and night vision. Electroretinography findings of reduced a and b waves in the right eye, together with a fundoscopic appearance of a mottled retinal pigment epithelium, attenuated blood vessels and optic disc pallor were consistent with unilateral cancer-associated retinopathy. Posterior subtenon injections of triamcinolone were administered to control active disease. With periocular steroid injections, at 4 years, our patient's visual acuity remained relatively stable and her condition persisted strictly unilaterally. Cancer-associated retinopathy may be the first presenting sign of an underlying malignancy or may indicate its recurrence. Moreover, in patients with a diagnosed gynaecological malignancy, visual symptoms could reflect cancer-associated retinopathy. In our patient visual symptoms came secondary to the diagnosis of cancer.
