Abstract
The aim of this study was to conduct a Rapid Assessment of Avoidable Blindness in Narail and Jamalpur districts to estimate the prevalence and causes of blindness in people aged 50 years or older
Narail
- The all-age prevalence of blindness for Narail is estimated to be 0.34%.
- The all-age magnitude of blindness for Narail is estimated to be 2,551 people out of a population of 0.765 million.
- Avoidable causes of blindness (operated and un-operated cataract, refractive error and corneal scar) accounted for 80% of blindness, 92% of severe visual impairment and 93.5% of visual impairment.
- Cataract (73.8%) and sequelae related to cataract extraction (4.6%) accounted for 78.4% of all causes of bilateral blindness.
- Posterior segment disease (including glaucoma, diabetic retinopathy and age-related macular degeneration) is responsible for 20% of bilateral blindness.
- 67.6% of people with bilateral cataract VA<3/60 had had surgery and 44.9% at VA<6/18.
Jamalpur
- The all-age prevalence of blindness for Jamalpur is estimated to be 0.35%.
- The all-age magnitude of blindness for Jamalpur is estimated to be 8,189 people out of a population of 2.31 million.
- Avoidable causes of blindness (operated and unoperated cataract, refractive error and corneal scar) accounted for 73.7% of blindness, 86.8% of severe visual impairment and 96.2% of visual impairment.
- Cataract (52.6%) and sequelae related to cataract extraction (5.3%) accounted for 57.9% of all causes of bilateral blindness.
- Posterior segment disease (including glaucoma, diabetic retinopathy and age-related macular degeneration) is responsible for 26.3% of bilateral blindness.
- 77.9% of people with bilateral cataract VA<3/60 had had surgery and 61.2% at VA<6/18.
