Coincidental ocular findings during retinopathy of prematurity telescreening of 9105 neonates.

PURPOSE: To describe the magnitude and spectrum of abnormal ocular findings other than retinopathy of prematurity (ROP) detected during an ROP telescreening programme.

METHODS

Retrospective review of the records of all premature babies screened for ROP from August 2015 to December 2019.

RESULTS

A total 9105 babies were screened during the study period with total 17,075 imaging sessions. Non-ROP ocular abnormalities were seen in 566 eyes of 383 babies (4.2%) including 207 male (54%) and 176 female babies (46%). Posterior segment abnormalities were seen in 88.2% babies (338/383) with haemorrhage being the most common (77%, 295/383). Anterior segment pathologies were seen in 12% babies (46/383) with congenital cataract being the most common pathology requiring surgical intervention. Other findings included globe abnormalities in 0.8% babies (3/383), adnexal disorders in 0.5% babies (2/383) and squint in 0.3% babies (1/383). Rare life-threatening conditions such as retinoblastoma and lipaemia retinalis were also detected. Eighty-seven babies (22.7%) were diagnosed with referral-warranted non-ROP pathologies, with an overall prevalence of 1% (87/9105). Prompt surgical intervention was advised for 7.3% babies (28/383), 3.4% babies (13/383) were treated medically and 4.2% babies (16/383) needed visual rehabilitation for non-amenable pathologies.

CONCLUSION

This is the largest study describing the magnitude and spectrum of neonatal ocular pathologies other than ROP in a cohort of premature babies. Digital imaging has a significant impact on early detection and timely intervention for various vision as well as life-threatening non-ROP pathologies, which would have been missed or delayed otherwise.
