Recent trends of ocular complications in patients with atopic dermatitis

To elucidate the recent trends in prevalence and characteristics of ocular complications of atopic dermatitis (AD).

Cross-sectional observational study.

Among AD patients who visited our department between 2012 and 2015, 70 patients (140 eyes; recent AD group) who gave informed consent to participate in the study were analyzed. Following a medical interview, ophthalmological examinations were conducted for ocular complications related to AD. The data were compared to those of 280 AD patients (560 eyes) analyzed in a similar study conducted at our department in 1991-1993 (previous AD group).

Blepharitis was found in 58 eyes (41%) in the recent AD group, and the frequency was significantly lower compared to the previous AD group (294 eyes, 53%) (p < 0.05). Tears in retina or pars plana ciliaris occurred in 22 eyes (4%) in the previous AD group, compared with none in the recent AD group (p < 0.01). Retinal detachment was observed in 12 eyes (2%) in the previous AD group, and none in the recent AD group (p < 0.01). Atopic keratoconjunctivitis (AKC) increased significantly in the recent AD group compared to the previous AD group (74.3% vs. 39.5%) (p < 0.001). Patients with a habit of slapping around the eye decreased significantly from 32.5% in the previous AD group to 12.1% in the recent AD group (p < 0.001).

Ocular complications in AD patients show a trend of decrease in recent years, which presumably is attributed to educational activities to increase patient awareness and advances in therapeutic strategy.
