Red reflex test is mandatory in NZ and many other countries X Congenital cataracts 2,3 X Retinoblastoma 4,5 X 4/5 screeners have not had any formal training for red reflex screening. 3 X Sensitivity of 4% for posterior disease 6 American Academy of Pediatrics, Policy Statement, 2008

6 Universal Newborn Eye Screening China 10 (Li et al 2013) 3573 infants 24.4% abnormalities India 11 (Vinekar et al 2015) 1021 infants 4.7% abnormalities

7 Aim: To identify the prevalence of ocular abnormalities, including retinal haemorrhages, in a New Zealand newborn population.

8 NZ-UNES Method Prospective observational study n = 350 Exclusion criteria 30 weeks gestational age 1250g birth weight Images captured include Anterior eye with red reflex Posterior pole and peripheral retina

9 NZ-UNES Method Ophthalmology review of all images Detected abnormalities: Retinal haemorrhages were re imaged at 6 weeks 12 Other detected abnormalities were appropriately referred

10 NZ-UNES Results N = 346 Median age at screening 2 days Indian 9% Māori 7% Pacific Peoples 6% Ethnicity NZ European 50% Chinese 12% 51.5% 48.5% Other 16%

11 NZ-UNES Results Delivery Modality N = 346 Median age at screening 2 days Ventouse 9% Forceps 4% Normal vaginal delivery 39% Emergency C section 26% 51.5% 48.5% Elective C section 26%

12 Ocular Abnormalities Incidence 57/346 (16.5%) Haemorrhage 53/346 (15.3%) Other abnormalities 5/346 (1.4%) Congenital cataract Optic nerve hypoplasia Choroidal haemangioma CHRPE

13 Haemorrhages Presentation Bilateral n = 35 Unilateral n = 16 Optic nerve 49.0% Macular 30.4% Extensive 67.6% Retinal haemorrhages were associated with delivery modality p<0.0005

14 Retinal Haemorrhages Forty-two infants attended follow up Mean follow up time was 51 ± 15 days Of the cohort two infants did not have complete resolution

15 Discussion Ocular abnormality rates varied between NZ, China and India Abnormality rate Excluding haemorrhages Haemorrhages China Li et al (n = 3573) 24.4% 2.8% 21.6% India Vinekar et al (n = 1021) 4.7% 2.3% 2.4% NZ-UNES (n = 346) 16.5% 1.4% 15.3% USA Callaway et al (n = 202) 20.3% Retinal haemorrhages were associated with delivery modality Birth-related retinal haemorrhages, in particular macular haemorrhages, have unknown long-term outcomes 15

16 Newborn screening in NZ 0.1% 16.5% 0.2% Ocular abnormalities were identified at a significantly higher rate than other established screenings in New Zealand (16.5%) Cost estimate of $2 million per year for New Zealand

17 UNES Conclusions Our data shows that wide-field digital imaging of the anterior and posterior eye is an effective tool for universal newborn eye screening UNES detected significant ocular abnormalities including retinal haemorrhage, congenital cataract and optic nerve hypoplasia Further research into the long-term affect of birthrelated retinal haemorrhages is required
