Geographic Representation of Authorship in Ophthalmic Research from Low- and Middle-Income Countries

ABSTRACT

Purpose

Low- and middle-income countries (LMICs) are underrepresented in ophthalmic research, despite carrying the highest burden of visual impairment. To assess the representation of local authors in global ophthalmic research, this cross-sectional, bibliometric analysis measured the proportion of LMIC-affiliated authorship in LMIC-based ophthalmic research.

Methods

We sampled original, primary research conducted in LMICs and published in 1 of 7 high-impact ophthalmic journals between 2017 and 2021. For each article, we extracted the number and name of country study site(s), country affiliation(s) of first and last author, proportion of LMIC-affiliated authors, funding sources, and study design.

Results

Of the 1,333 studies exclusively conducted in LMICs, 89.4% of first authors and 80.6% of last authors were exclusively LMIC-affiliated. Representation of LMIC-affiliated first authors were lower in studies based in low-income countries (25.0%) or in sub-Saharan Africa (26.5%), published in journals with higher impact factors (68.0% in Ophthalmology), funded by high-income countries (HICs) (41.4%), or conducted in both LMICs and HICs (27.1%). The United States, United Kingdom, and Australia had the 3^rd, 6^th, and 8^th largest shares of last authors. There were only 12 single-country studies conducted in low-income countries, namely Ethiopia, the Gambia, Guinea, Liberia, the Niger, and Sierra Leone. Of these countries, only three held first authorship and one held last authorship.

Conclusions

Although LMIC-based ophthalmic research has demonstrated higher local authorship representation compared to other fields, underrepresentation can be exacerbated by country income level, journal “prestige,” and degree of HIC involvement. These discrepancies highlight the need for more equitable data ownership in global ophthalmic research.
