PURPOSE: We present rates of acute primary angle-closure glaucoma (APACG), peripheral iridotomy (PI) and cataract surgery in Scotland between 1998 and 2012. METHODS: The number of patients in Scotland with APACG in each of the years between 1998 and 2012 was obtained from Information Service Division (ISD) Scotland. Data was also obtained for patients who had undergone laser PI and cataract surgery. The annual rates of APACG, PI and cataract surgery were calculated using Scotland's population data during each of these years. RESULTS: Between 1998 and 2012 the rate of APACG in National Health Service patients decreased by 46.4% (from 46.7 to 25.0 per million, p < 0.005). The rate of PI increased overall by 116.3% (from 38.0 to 82.2 per million), but demonstrated a decrease of 48.2% (38.0 to 19.7 per million, p = 0.002) between 1998 and 2008, and an increase of 317.3% (19.7 to 82.2 per million, p = 0.005) between 2008 and 2012. Over the same 15-year period, cataract surgery increased by 73.4% (from 354.2 to 615.2 per 100,000, p < 0.005). In this timeframe, mid-year Scottish population estimates increased by 4.6%. CONCLUSION: Our results demonstrate a significant reduction in the rate of APACG in the Scottish population between 1998 and 2012, along with a rising rate of PI and cataract surgery. The trend of decreasing APACG may be due to the increasing rate of cataract surgery in the same time period. This parallels patterns seen in other European countries. We discuss these findings together with other related epidemiological factors.
