The comparison of glaucoma prevalence in the Republic of Bashkortostan

PURPOSE: The purpose of the research is to study glaucoma prevalence in the Republic of Bashkortostan (RB) over the 20-year period (1999-2018 years).

METHODS: This research was conducted using the data from statistic annual reports of ophthalmologists from various cities and regions of RB, the Ufa Eye Research Institute with assistance from the Head Office of Medical and Social Examination Service in RB.

RESULTS: In 2018 there were 33 727 people with glaucoma in RB (81.5% with primary open-angle glaucoma — POAG). 73.8% of them were over the age of 60 and 83.3% patients had mild or moderate glaucoma. During periodic health examination there were 1.2% patients with suspected glaucoma and 0.6% with an established diagnosis. During the period from 1999 to 2018 there was a 112.8% increase in patients registered in dispensaries, a 77.4% increase in prevalence and morbidity from POAG, while there was a decreasing trend in the number of blind people and people primary identified as disabled associated with glaucoma.

CONCLUSION: The 20-year period analysis (1999-2018) showed that there was more than a two-fold increase in the number of officially registered patients with glaucoma in the Republic of Bashkortostan: from 15 852 to 33 727. But despite the progressive growth of glaucoma incidence, particularly primary open-angle glaucoma (from 9.3 to 16.5 per 10 000 people over the age of 40) there was a 30% reduction in blindness prevalence over the last 9 years (since 2010) — from 17.3 to 13.0 and a 37% reduction in absolute number of people with glaucoma-related disability — from 346 to 218. It was a complex result of high level of check-ups and periodic health examinations in Republic followed by an increasing number of identifications of patients with early glaucoma, active and wide use of topical medicines and a persistently high surgical activity.
