In 2023, the share of corresponding/leading authors in optometry publications in Brazil was notably higher than forecasted in subsequent years, indicating a sharp decline projected to 2028. Year-on-year variations between 2024 and 2025, and onwards show a consistent decrease, leading to a significant five-year Compound Annual Growth Rate (CAGR) decline. The trend reveals diminishing representation of Brazilian authors in a leading role, necessitating strategic focus on enhancing local research capabilities and collaborations.

Future trends to watch:

Development of support programs for local researchers to mitigate the forecasted decline.
Potential increase in international collaborations impacting authorship roles.
Enhanced training and resources for Brazilian researchers to maintain competitive publication presence.
