Abstract

Background/Aims
Spondyloarthritis represents a chronic inflammatory condition primarily targeting the joints of the spine. Uveitis stands as the most common initial extra-articular manifestation of axial spondyloarthritis (SpA), occurring in up to a third of patients. There is a diagnostic delay in axial SpA, with studies showing that the time from symptom onset to diagnosis is 5-7 years. The delay of diagnosis can be attributed to the non-specific presentation of chronic back pain as well as late ophthalmology referrals to rheumatology. A previous audit in our department showed that 25% of uveitis patients who were clinically indicated to have been referred to rheumatology were not. One main objective was to implement the use of the MSK Rheumatology Inflammatory Back Pain Questionnaire as a referral tool, to find out whether the relevant history and questions were asked to all uveitis patients, to mitigate diagnostic delays and enable early management.

Methods
Patients presenting to the uveitis clinic at NGH were reviewed prospectively from May 2023-July 2023. Medi-viewer/Symphony were used to see patient details, whether the patients were already under rheumatology, any previous episodes and family history. The MSK Rheumatology Inflammatory Back Pain questionnaire was completed by all attending patients. It included 12 questions; a score ⩾4 signified a need for referral.

Results
A total of 40 patients (M:F ratio 2:3, mean age 52) presented to the uveitis clinic and were reviewed. All patients with uveitis were investigated with the relevant blood tests to rule out any inflammatory conditions. 16 patients were HLA B27 positive. All patients were asked to complete MSK Rheumatology Inflammatory Back Pain questionnaires to rule out inflammatory disease. 60% had back pain history before the age of 45, 21 were of inflammatory type of pain, 15 had disturbed second half of sleep. 25% of patients had other positive inflammatory markers. 40% of patients had a strong family history of HLA-B27. 67% scored ⩾4 on our questionnaire. 23% were already under rheumatology care, 20% were referred to rheumatology and 23 were not referred, of which 13/23 scored ⩽4. The remaining 10 were not referred due to awaiting blood results, further follow up, or lack of systemic features resulting in discharge.

Conclusion
Uveitis ranks among the most frequent occurrences in the field of ophthalmology, with a significant proportion being associated with HLA-B27. A considerable 40% of uveitis patients have undiagnosed spondyloarthritis due to inadequate referrals. A comprehensive questionnaire and utilising pain scoring can serve as effective tools for directing patients toward proper evaluation for inflammatory diseases. Our study shows that only appropriate cases were referred and had relevant investigations before referral, underscoring the importance of a partnership between ophthalmology and rheumatology to optimise the management of inflammatory spondyloarthritis.
