Cataract blindness in Hungary.

AIM: To estimate the prevalence of blindness and visual impairment resulting from cataract in the population aged ≥50y in Hungary, and to assess the cataract surgical services. METHODS: A rapid assessment of avoidable blindness (RAAB) was conducted. A total of 3523 eligible people were randomly selected and examined. Each participant underwent surgery for cataract was interviewed with regard to the year, place, and costs of the surgery. Participants with obvious cataract were asked why they had not yet undergone surgery (barriers to surgery). RESULTS: An estimated 12 514 people were bilaterally blind; the visual acuity (VA) in 19 293 people was <6/60, and the VA in 73 962 people was <6/18 in the better eye due to cataract. An estimated 77 933 eyes are blind; 98 067 eyes had a VA of <6/60, and an estimated 277 493 eyes had a VA of <6/18 due to cataract. Almost all cataract surgeries were conducted in government hospitals. The age- and sex-adjusted cataract surgical coverage with VA<3/60 in eyes was 90.0%. The rate of good visual outcome after surgery was 79.5%. Ocular comorbidity was the main cause of poor outcome (78.1%), followed by late complications (such as posterior capsule opacification) (17.2%), inadequate optical correction (3.1%), and surgical complications (1.6%). The main barrier to surgery in people with bilateral cataract and VA of <6/60 was 'need not felt'. CONCLUSION: The prevalence of visual impairment resulting from cataract is slightly higher than expected. The quality of the cataract surgical service seems adequate in Hungary. However, the number of cataract operations per year should continue to increase due to the increasing patient demands and the aging population.

Diabetes and diabetic retinopathy in people aged 50†years and older in Hungary.

BACKGROUND/AIMS: The purpose of this study was to estimate the prevalence of diabetes mellitus (DM) and diabetic retinopathy (DR) in the population aged 50 years and older in Hungary, and to assess the coverage of diabetic eye care services. METHODS: In total, 105 clusters of 35 people aged 50 years or older were randomly selected. The standardised rapid assessment of avoidable blindness (RAAB) with the diabetic retinopathy module (DRM) was used. Participants were classified as having DM if they were known to have DM or if their random blood glucose level was ≥200 mg/dL. Dilated fundus examination and Scottish DR grading were performed. RESULTS: In total, 3523 (95.9%) out of 3675 eligible subjects were examined. And 705 (20.0%) out of 3523 had known (661) or newly diagnosed DM (44). Twenty per cent of participants with known DM had a blood glucose level ≥200 mg/dL, and 27.4% had never had an ophthalmological examination for DR. Prevalence of DR and/or maculopathy was 20.7% and prevalence of sight-threatening DR (STDR) was 4.3% in one or both eyes among participants with DM. CONCLUSIONS: Prevalence of DM was in line with findings of other RAAB+DRM surveys and slightly lower than the unpublished earlier age-matched Hungarian estimate. Prevalence of DR was slightly lower than expected. The prevalence of STDR was low in people aged 50 years and older in Hungary compared with the results of other RAAB with DRM surveys. DR screening coverage was low. To prevent severe complications of DM and possible concomitant visual loss, the coverage of ophthalmic examinations in patients with DM should be increased.
