Certification of Visual Impairment due to Diabetic Eye Disease in Northern Ireland From 2014 to 2019

Purpose: To determine the number of people being certified as either severely sight impaired or sight impaired due to diabetic eye disease (DED) in Northern Ireland (NI). Methods: Sight impairment data have been collected for the 6-year period of 2014–2019, these data included age, gender, certification status, visual acuity, and type of eye disease. All data were entered into an Excel database and analyzed using Stata to ascertain the number of total certifications and diabetic eye disease certifications per year. Results: The number of total certifications in NI increased year on year as has the number of diabetic eye disease certifications. The number of diabetic eye disease certifications rose from 12.6 per million in 2014 to 17.4 per million in 2019, with a peak of 27 per million in 2018. There were more males than females registered due to diabetic eye disease. Diabetic eye disease's proportional representation of total certifications of visual impairment remained relatively stable during the 6-year period. Conclusions: In the 6-year period, the overall number of certifications has increased from 2014 to 2019, as have the number of certifications due to DED. This may be attributed to the improvement of certification and diabetic eye care pathways. People with diabetes who are certified are more likely to be younger and male. More research with medical data needs to be conducted in the future.
