Ocular GCA Symptoms Prompt Intervention Faster than Others, Study Finds

Giant cell arteritis (GCA) is an inflammatory condition affecting the arteries. If left untreated, it can lead to sudden, painless and permanent vision loss.

A retrospective multicenter cohort study in American Journal of Ophthalmology found that ocular symptoms led to the shortest diagnostic delay in biopsy-proven giant cell arteritis (GCA) compared to other symptoms, such as headaches. Researchers also focused on how the presenting symptoms and initial provider specialty affected time to treatment.The authors obtained data from a national veteran health database. They started with 24,857 patients who were diagnosed with GCA or who had undergone temporal artery biopsy procedures between 2001 and 2022. After filtering patients by exclusion criteria, they confirmed 300 cases of GCA for final analysis. The investigators defined a true positive biopsy according to American College of Rheumatology criteria, which the authors described in the paper as having “a clearly stated diagnosis,” “classic histopathological findings” or “healed arteritis, indicated by a mononuclear infiltrate with insufficient classic findings but determined to be GCA by rheumatologic clinical correlation.”The participants were predominantly male (94.3%) and white (89.9%), with 8.3% identified as Black and 4% not identified as any specific race. Subjects’ mean age was 75.3. The study captured presenting symptoms, initial provider specialty and patients’ exact diagnostic timelines from symptom onset to the first clinical visit and from that visit to corticosteroid initiation.The researchers reported that patients waited an average of 22 days “from symptom onset to their first clinical visit” and 11 days from the first visit to treatment initiation. Individuals first evaluated by emergency department or eyecare providers received treatment significantly sooner than those seen by primary care providers, and presenting symptoms shaped the timeliness of treatment. Patients with ocular symptoms, including transient vision loss and visual disturbances, underwent treatment more promptly at a mean of 8.3 days from symptom onset compared to those with headache (12.9 days) or systemic complaints (20.2 days). Classic symptoms, such as scalp tenderness and temporal pain, were also noted to lead to “the shortest delays following examination.”The authors noted that “visual symptoms prompt more rapid diagnosis and treatment, whereas nonspecific symptoms result in significant delays, particularly in primary care settings.” These results highlight a need for improved provider education and systematic approaches to recognize and manage GCA in its varied presentations, as early diagnosis remains critical to prevent irreversible vision loss and other complications.Click here for the journal source.
