Active uveitis remained in 43.4% of juvenile idiopathic arthritis (JIA) patients up to 40 years after a diagnosis, based on data from 30 individuals.
Uveitis occurs in approximately 10%-20% of patients with JIA, but data on the long-term activity and prevalence are limited, although previous studies suggest that uveitis can persist into adulthood, wrote Dr. Angelika Skarin of Skåne University in Lund, Sweden, and colleagues.
In a study published in Pediatric Rheumatology, the researchers reviewed ophthalmic records from 30 JIA patients at a mean of 40.7 years after uveitis onset. They compared these records to data collected from the same patient population at a mean of 7.2 and 24.0 years after onset. In the previous follow-up studies, 49% of the patients had active uveitis at 24 years, and the prevalence of cataracts and glaucoma increased between the 7-year and 24-year assessments.
In the current study, 43.4% of the population had active uveitis at the 40-year follow-up, which corresponded to 23.6% of the original study cohort. The mean age of the participants overall was 46.9 years, the mean duration of joint disease was 42.99 years, and the mean time from onset of uveitis was 40.7 years.
In addition, 66.6% of the patients in the current study had cataracts or had undergone cataract surgery in one or both eyes, and 40.0% had glaucoma.
By the time of the current study, of the original cohort of 55 individuals, 11 were deceased; rheumatic disease was declared the main cause in four patients and a contributing factor in three others.
Potential drivers of the earliest cases of glaucoma and ocular hypertension (G/OH) include increased intraocular pressure as a result of topical corticosteroid treatment, the researchers noted in their discussion. However, G/OH occurring later than the 7-year follow-up was “more likely to be the type observed in many patients with long-standing chronic uveitis, where a gradual increase in intraocular pressure is assumed to be caused by impaired aqueous outflow,” they said.
Only 4 of the 30 patients did not have regular ophthalmology visits, which suggests a study population with ocular symptoms or concerns about their eyesight, the researchers wrote. “The fact that 13% of our original cohort were reported to have severe visual impairment or worse in both eyes at any of the three follow-ups is noteworthy,” compared to reports of visual impairment of less than 0.5% in a German study in the general population for similar ages.
The findings were limited by several factors, including the retrospective design, small study population, and lack of data on 25 of the original 55-member study cohort, which may reduce the reliability of the current study, the researchers noted. However, the results reflect data from previous studies and support the need for JIA patients to continue regular ophthalmic checkups throughout life, they concluded.
The study was supported by Stiftelsen för Synskadade i f.d. Malmöhus län, Sweden, Skånes Universitetssjukhus Stiftelser och Donationer, Ögonfonden, and the Swedish Society of Medicine. The researchers had no financial conflicts to disclose.
