Preferred Treatment Patterns of Retinopathy of Prematurity: An International Survey

Abstract

This paper assesses the preferred treatment patterns for retinopathy of prematurity (ROP) and examine trends in anti-vascular endothelial growth factor (VEGF) use for ROP. Methods: A retrospective survey consisting of 14 questions was distributed to paediatric ophthalmology interest groups internationally. Main outcome measures included treatment patterns, proportion of anti-VEGF use in different stages of ROP; and comparison of first-line treatments as well as repeat anti-VEGF treatments. Results: Fifty-four ophthalmologists from 11 different countries responded to the survey. The number of respondents per question, except one, ranged between 50–54. Per annum, there was an average number of 394 infants screened by each respondent. Anti-VEGF was the preferred treatment method for aggressive (A)-ROP (64.1%), Type 1 ROP in zone 1 (71.7%), and Type 1 ROP in posterior zone 2 (56.6%). The majority used laser as the first-line treatment of Type 1 ROP in anterior zone 2 (73.6%) and Type 1 ROP in zone 3 (79.2%). Laser was the preferred treatment modality utilised in infants requiring repeat treatment following anti-VEGF injection. The preferred anti-VEGF agent was bevacizumab administered at a dose of 0.625 mg. Conclusions: Anti-VEGF as first-line therapy has been increasing. Anti-VEGF appears to be the first-line treatment of choice for A-ROP, Type 1 ROP in zone 1 and posterior zone 2 and laser for Type 1 ROP in anterior zone 2 and zone 3.
