Abstract

Purpose : The socioeconomic distribution of retinopathy of prematurity (ROP) has evolved, where middle-income nations are currently experiencing epidemics. We hypothesize that ROP research from middle-income nations has also increased. We therefore conducted a bibliometric analysis to evaluate the publication trends of ROP literature.

Methods : A search for indexed English abstracts using search terms of "retinopathy of prematurity" or "retrolental fibroplasia" was performed in PubMed from 1976 to 2015, and divided into 4 decades. Original research articles involving human subjects were included. Countries were grouped into high-, middle-, and low-income groups using World Bank criteria based on the population being studied, and impact factors (IF) were gathered from 2014 Thomson Reuters Journal Citation Reports.

Results : A total of 5,425 publications were identified, of which 2,045 met inclusion criteria. The ratios of publications per decade were: 1976-1985 (5.4%), 1986-1995 (15.8%), 1996-2005 (25%), 2006-2015 (53.7%). The ratios of publications per income group were: high- (82.2%), middle- (17.7%), low- (0.1%). Respective mean (SD) IFs by income group were: 2.79 (±4.87), 1.23 (±1.17), 0.42 (±0.45). Top producing countries were USA (37%), UK (6.7%), India (4.6%), Japan (3.9%), and Turkey (3.5%). Most common journals were Arch Ophthalmol (6.5%), J AAPOS (5.5%), Ophthalmology (5.5%), Br J Ophthalmol (5.3%), and J Pediatr Ophthalmol Strabismus (5%). Study types were: cohort (41%), case series (23%), case control (9%), case report (8.4%), clinical trial (7.4%), cross-sectional (4.3%), brief report (2.9%), and meta-analysis/systematic review (2.8%). Telemedicine/image analysis papers comprised of 4.7%. There was a correlation between time and number of publications (Pearson r = 0.93, p < 0.01), and a difference between the number between high- and middle-income groups (p < 0.01). Middle-incoming nations were increasingly producing more papers (p < 0.01), but in lower IF journals overall (p < 0.01) (Table 1).

Conclusions : Investigators from middle-income nations are increasingly contributing to ROP literature, but overall, may not be recognized in high-impact journals compared to literature from high-income nations.
