Papilloedema can be the first sign of life-threatening disease. Its importance was highlighted in 2016 when optometrist, Honey Rose, was convicted of gross negligence manslaughter for not identifying papilloedema in a child who later died [1]. As the detection of papilloedema relies entirely on fundal examination and/or imaging that were relatively contraindicated among non-eyecare clinicians during the COVID-19 pandemic, we were concerned about the impact of the pandemic on hospital attendances of patients with papilloedema.
With National Health Research Authority ethical approval (IRAS: 306282), we extracted anonymised data on new patients attending the Accident & Emergency (A&E) and neuro-ophthalmology services at Bristol Eye Hospital (BEH) from Trust electronic patient records. Our analysis only included adults with suspected papilloedema because of headaches and/or indistinct optic disc margins and excluded patients with other causes of optic disc swelling (e.g., ischaemic optic neuropathy, optic neuritis, giant cell arteritis). Children were excluded because they are normally directed elsewhere within the Trust. Referrals were further classified as “true” or “false”-positives depending on whether papilloedema was confirmed by subsequent investigation.
As expected, fewer patients with suspected papilloedema attended BEH during the first lockdown (23 March to 14 June 2020) than before or afterwards. However, the impact was greatest on the large proportion of false-positive referrals before (78.1%; 118/151), during (64.3%; 36/56), and after lockdown (79.7%; 141/177). Surprisingly, 60.1% (179/295) of false-positives actually had normal optic discs: 55.9% (100/179) of these had headaches but normal eye examinations, 7.3% (13/179) had non-specific visual symptoms; and 36.9% (66/179) were asymptomatic. True-positive cases were diagnosed with idiopathic intracranial hypertension (49%; 44/89), space-occupying lesions (10%; 9/89) and other aetiologies (41%; 39/89) but there was no evidence that any true-positive cases were missed (Fig. 1).
We were interested to know whether the large proportion of false-positive referrals for suspected papilloedema dated back to the widespread media coverage of the Honey Rose case in July 2016, when others had reported increased demand on their NHS services [2]. Indeed, false-positive referrals had jumped from 33.3% in 2015 to 60.9% in 2016 while pressure on the neuro-ophthalmology service had increased by 500–600% (Fig. 2).
With the introduction of optometrist-led community services for minor eye conditions (MECS) and COVID-19 urgent eyecare (CUES), and the decline in ophthalmology teaching at undergraduate level [3], optometrists have become de facto gatekeepers to NHS secondary eyecare services. Yet, concerns about missing sight- or life-threatening diagnoses, like papilloedema, has meant referral thresholds have decreased since Honey Rose. Further, the introduction of OCT to many optician practices [4] has increased referrals of patients who don’t need medical treatment, not decreased them [5]. Although patients with suspected papilloedema are proportionately few (~1% A&E and 8–12% neuro-ophthalmology attendances), substantial healthcare costs are accrued by unnecessary hospital appointments, investigations, time off work, longer waiting times, and by increasing personnel/clinic capacity to meet higher service demands. Given the huge backlog in appointments and operations caused by COVID-19, the time is ripe to rethink how primary and secondary eyecare services could work better together to serve the patients who need them most.
