Purpose:
To report the demographics and clinical characteristics of patients with a primary retinal detachment (RD).
Design:
Prospective cohort study by a registry design.
Participants:
Patients with RD treated at vitreoretinal sub-specialty institutions in Japan from February 2016 to March 2017.
Methods:
Descriptive statistics for the primary RD, and multivariable ordered logistic regression and multiple linear regression analyses were performed.
Results:
3178 eyes of 3178 cases were analyzed. The interval from onset to surgery was significantly shorter in patients in the 40-year age group than in other age groups except for the 50-year age group (P<0.05, Steel-Dwass test). The proportion of complex cases was significantly higher in the 10-year, 70-year, and 80+ year age groups than in the 40 and 50-year age groups (P<0.05, Steel-Dwass test). The size of RD was significantly associated with the male sex (odds ratio, 1.29; 95% confidence interval [CI], 1.07 to 1.56; P=0.0085) and the interval from onset to surgery (odds ratio, 1.03 95% CI, 1.01 to 1.04; P=0.0014). Low IOPs in eyes with RD were significantly associated with an older age (-0.24 mmHg/10 years, 95% CI, -0.32 to -0.16], P<0.0001) and larger RD area (-0.91 mmHg/quadrant, 95% CI, [-1.06 to -0.76], P <0.0001).
Conclusion:
Profile and clinical characteristics of patients with a primary RD were not exactly the same as previous reports. A preoperative low IOP was associated with several ocular factors while the area of RD was associated not only with ocular but with social factors as well.
