title: Magnitude and determinants of diabetic retinopathy among persons with diabetes registered at employee health department of a tertiary Eye Hospital of central Saudi Arabia.
abstract: BACKGROUND
  To estimate the magnitude and determinants of diabetic retinopathy (DR) among persons with diabetes registered at the employee health department of King Khaled Eye Specialist Hospital (KKESH).
  
  
  METHODS
  A retrospective review of medical records was conducted in 2013-14 at KKESH. The case record review extracted demographic, profile of diabetes, diabetic complications, and different blood indices to determine the status of potential risk factors. Ocular profile, especially DR was also noted.
  
  
  RESULTS
  Our cohort had 94 staff with diabetes. Eye examination was carried out in 51 (54.8%) of them. The rate of DR was 52% (95% confidence interval (CI) 28-66). Sight-threatening diabetic retinopathy (STDR) (proliferative DR and/or diabetic macular edema) was present in 40% of those examined. Good glycemic control was noted in 42% of participants. Duration of diabetes was associated with DR (P = 0.04). Good glycemic control was negatively associated to DR (odds ratio = 0.2 [95% CI 0.04-0.6]). The coverage of eye screening was 55% only. Laser treatment was given to 80% of STDR cases. The lens opacity and glaucoma rate was 15% and 8.3%, respectively.
  
  
  CONCLUSIONS
  Low coverage for eye screening and laser treatment to diabetics among the staff of an eye hospital is a matter of concern. The underlying causes of low coverage of screening, digital fundus photography as a screening tool and management should be addressed.
