Temporal artery biopsy in ophthalmology: a useful investigation
Sir,We read with interest the article by Lenton et al. entitled Does temporal artery biopsy influence the management of temporal arteritis?.1 An audit of temporal artery biopsies carried out over a 13-month period at the Princess Alexandra Eye Pavilion in Edinburgh revealed quite different results. Of the 35 biopsies carried out, 11 (31%) were positive, 23 (66%) were negative and one was inadequate. Of the patients with a negative result, two of the patients who had been started on high-dose corticosteroids prior to biopsy had treatment continued for >3 months, and none were started on steroids after the result became available.
The population involved in our study is quite different from that studied by Lenton et al. All our patients had both presented to and been assessed by an ophthalmologist, and a large proportion had either visual symptoms or temporal headache. However, we also compared our positive biopsy rate with all biopsies carried out by other specialists in Lothian over the same time period, and found a very similar (32%) positive biopsy rate.
In our experience, the biopsy result is generally acted upon and is considered a very useful component of the diagnostic process. Within the department, the decision to biopsy and/or commence corticosteroid treatment is usually made by the team that will be responsible for the patient's longer-term care. The biopsy can be done within 5 days of presentation, and follow-up arranged thereafter with the same team. This integrated approach allows for careful consideration of the indications and potential complications of biopsy, so that when it is considered necessary, the result is generally acted upon.
