To estimate the population-based incidence rates of blindness registration and their trends over time in Western Australia.
A retrospective review was performed on all cases of bilateral blindness registered with the Association for the Blind of Western Australia between 1984 and 2002. The causes and mean age at blindness registration were ascertained and incidence rates of blindness due to various causes were calculated.
A total of 3852 blind certificates were examined. From 1984 to 1994, the annual incidence of registered bilateral blindness decreased significantly at an average rate of 9.4% per year (p < 0.0001), but then rose at a mean rate of 4.1% per year (p < 0.0001). ARMD blindness similarly fell by 8.9% per year (p < 0.0001), but then rose after 1994 by 4.5% per year (p < 0.0001). The incidence due to glaucoma decreased at an average rate of 10.3% per year (p < 0.0001) until 1994 and then rose at 7.4% per year at borderline significance (p = 0.025).
There has been a nonlinear decrease in the incidence of registered blindness, in particular glaucoma-related blindness, in Western Australia. Rates of total registered blindness and that due to ARMD fell from 1984 to 1994, but have risen since.
评估西澳大利亚州基于人群的失明登记发病率及其随时间的变化趋势。
对1984年至2002年间在西澳大利亚州盲人协会登记的所有双侧失明病例进行回顾性研究。确定失明登记的原因和平均年龄，并计算各种原因导致的失明发病率。
共检查了3852份失明证明。1984年至1994年，登记的双侧失明年发病率以每年9.4%的平均速率显著下降（p<0.0001），但随后以每年4.1%的平均速率上升（p<0.0001）。年龄相关性黄斑变性（ARMD）导致的失明同样以每年8.9%的速率下降（p<0.0001），但1994年后以每年4.5%的速率上升（p<0.0001）。青光眼导致的失明发病率在1994年前以每年10.3%的平均速率下降（p<0.0001），之后以每年7.4%的速率上升，具有临界显著性（p = 0.025）。
西澳大利亚州登记的失明发病率，特别是与青光眼相关的失明发病率呈非线性下降。1984年至1994年，登记的失明总数和因ARMD导致的失明发病率下降，但此后有所上升。
