Each of the many ways to measure impact has their strengths and weaknesses.5 Here, Expertscape and Google Scholar were selected. Expertscape computes the following (among others) to obtain a score:6
- Expertscape is a proprietary ranking that searches the PubMed database to find all the medical journal articles published about the topic (e.g. glaucoma) in the past ten years.
- It then assigns a score to each article, based on the article’s year of publication (recent is better), the article’s type (guidelines and reviews, for example, count more than letters to the editor), and the journal in which the article appeared (some journals are better than others). It also It assigns a score to each author of the article (first author scores higher than second author).
Google Scholar was searched on Glaucoma for each of the top 20 Expertscape authors to retrieve an “Only Glaucoma” h-index (no date restrictions were used). The “Only Glaucoma” h-impact does not necessarily correlate with the Expertscape rankings. “Only Glaucoma” h-impact scores will be ranked in a future list. There are limitations to this, some of which are:
- Spelling and commonality of names. All known initials of users were used to perform the query.
- Limitations and criticism of Google Scholar can be found at https://en.wikipedia.org/wiki/Google_Scholar.
In future issues other indices (including h-impact), parameters will be explored, e.g. time ranges, other indices, subspecialties, regions, citation metrics and many more. So, stay tuned for more ranking lists.

- Searches conducted by Simon Bakker for IGR between June 5 – 13, 2023 using Harzing, A.W. (2007) Publish or Perish: https://harzing.com/resources/publish-or-perish
- Solid bars represent Expertscape proprietary relative rank of impact.
- The score does not reflect the total h-factor. Only publications on glaucoma are used.
