ABSTRACT
Introduction:
Posterior segment diseases are the most common causes of blindness and visual impairment in devel-oped countries among people aged 50 years and older in Hungary.Objective:
The purpose of this study was to estimate the prevalence of visual impairment and blindness caused by posterior segment diseases in the population aged 50 years and older in Hungary.Method:
105 census enumeration units were randomly selected with a probability proportional to size by the Hungar-ian Central Statistical Office. The standardised Rapid Assessment of Avoidable Blindness (RAAB) method was used. Participants underwent eye examination with a direct ophthalmoscope. Participants underwent visual acuity testing with a Snellen tumbling E-chart with or without a pinhole. Dilated fundus examination was performed in diabetic participants using an indirect binocular ophthalmoscope.Results:
In total, 3523 (95.9%) out of 3675 eligible people were examined, of whom the prevalence of bilateral blind-ness and severe visual impairment was 0.7% and 0.2%, respectively. The most common causes of visual impairment caused by posterior segment diseases were age-related macular degeneration (1.419%), glaucoma (0.397%), diabetic retinopathy (0.341%) and rhegmatogenous retinal detachment (0.198%). The most common causes of blindness caused by posterior segment diseases were age-related macular degeneration (37.5%), glaucoma (16.7%), diabetic retinopathy (8.3%), high myopia (8.3%), rhegmatogenous retinal detachment (8.3%) and retinitis pigmentosa (8.3%).Conclusion:
Prevalence of severe visual impairment and blindness caused by posterior segment diseases was lower compared to results of RAAB surveys in other countries. The frequency order of different posterior segment diseases was in line with developed countries. Availability of eye care should be improved and financing should be modernized due to the continuously increasing number of patients with age-related macular degeneration, glaucoma, diabetes and pathologic myopia.Palabras clave
