Aims
Diabetic Retinopathy (DR) can deteriorate during pregnancy. Current guidelines recommend at least one eye-check during pregnancy, ideally one each trimester. Here we report adherence of pregnant women with pre-existing diabetes to recommended eye-screening guidelines in a prospective cohort study.
Methods
Pregnant women with type 1 (T1DM) or type 2 diabetes (T2DM) were prospectively recruited from two tertiary maternity hospitals in Melbourne. Barriers to attending eye-screening were assessed using the Compliance with Annual Diabetic Eye Exams Survey (which primarily comprises 5-point Likert scale items).
Results
Of the 163 patients approached, 136 (83.4%) participated. Mean age was 33.8 years (range 19-47). Sixty women (44%) had T1DM (median duration 16.5 years), while 56% had T2DM (median duration 3 years). Retinal assessment was performed at least once during pregnancy in 108 women (79.4%) and 15 (11%) received assessment once in each trimester. DR was present in 34 (31.5%) women. Women who failed to attend eye-screening responded differently to women who attended. Ninety-two percent of women who were not screened each trimester felt confident controlling their blood glucose compared to 60% of women who were screened (Kendall’s tau test, p=0.002); 31% of non-attendees agreed that yearly eye exams were not a top priority compared to 7% of attendees (p=0.015). Of women who failed to attend any eye-screening during their pregnancy, 32% believe that there is treatment for diabetic eye diseases versus 58% of screening attendees (p=0.011). Overall, respondents ranked obstetrics and endocrinology appointments their highest priority during pregnancy, whilst ophthalmology review was considered a much lower priority (median rank 5th out of 7 health appointments).
Conclusions
Despite the risk of DR during pregnancy, only 15 of 136 pregnant women with diabetes adhered to recommended screening guidelines, and women ranked eye health as a low priority. More proactive efforts to educate about the importance and treatability of DR and to integrate care are needed to prevent vision loss in this growing demographic.
