Abstract
Purpose :
We studied time series trends for incidence rates of rhegmatogenous retinal detachment (RRD) repair, retinal break (RB) treatment, posterior vitreous detachment (PVD), and cataract surgery (CS) to investigate seasonal variation and differences among age, race, and sex using the IRIS Registry.
Methods :
RRD repair, RB treatment, and CS were based on CPT codes. PVD diagnosis was based on ICD-9/10 codes. Daily incidence rates were calculated during a 5 year period (2014-2018) and defined as the ratio of number of patients diagnosed with RRD, RB, PVD, and CS to the total number of patients followed on a given day. CS group was included as a comparison for seasonal variation given its elective nature. Rates were stratified by decade of life (DOL), sex, and race.
Results :
A total of 2,996,982 patients were diagnosed with incident PVD. Patients undergoing RRD repair (n=248,765), RB treatment (n=367,323) and CS (n=6,132,138) were included. The mean daily incidence for RRD, RB, PVD, and CS were 0.5, 0.7, 5.1, 12.2 per 100,000 patients, respectively (Figure 1). The highest incidence of RRD was in the 5th and 6th DOL. Men had higher incidence of RRD repair than women, whereas women had higher incidence of PVD. RRD incidence was higher in Whites compared to others. Time series showing seven day moving average point incidence for RRD repair, RB treatment and PVD by sex and age demographics is shown in Figure 2. Seasonal variation in RRD repair, RB treatment, PVD, and CS corresponded to national holidays with larger fluctuations in winter months.
Conclusions :
The higher incidence of RD repair and RB treatment in men compared to higher PVD incidence in women may suggest an inherent sex-related risk. The seasonal variation associated with holidays was less pronounced for RRD repair and RB treatment.
