ABSTRACT
Purpose: The research activity in pediatric glaucoma (PG) was qualitatively and quantitatively evaluated using a scientometric approach. Methods: The “Web of Science” database was accessed for primary bibliometric data regarding PG using search terms “pediatric glaucoma,” “paediatric glaucoma,” “congenital glaucoma,” and “childhood glaucoma.” The data was analyzed for total research productivity, citations, and scientific output in terms of journals, countries, institutions, and authors. The results were further characterized for coauthorship links and visualized by VOS viewer software. Also, the top 25 cited articles were reviewed with the above bibliometric characteristics. Results: One thousand two hundred and sixty?nine items were obtained from our search query from 1955 to 2022; these received 15,485 citations, originated from 78 countries. The top?3 contributing countries were the United States of America (n = 369), India (n = 134), and China (n = 127). LV Prasad Eye Institute (n = 58), Duke University (n = 44), and King Khalid Eye Specialist Hospital (n = 42) were the top?3 productive institutes. The top?3 prolific authors were Mandal AK (n = 53), Freedman, SF (n = 36), and Sarfarazi, M (n = 33). Journal wise, “Investigative Ophthalmology” (n = 187), “Journal of Glaucoma” (n = 92), and “Journal of AAPOS” (n = 68) were the journals in which the most articles were published. The top?25 cited documents received 3564 citations and were published between 1977 and 2016. The key areas of interest were basic sciences (genetics of childhood glaucoma) and surgical management. Conclusion: United States of America, LVPEI, Mandal AK, and “Investigative Ophthalmology” were the top rankers as far as the productivity and publications related to PG are concerned. Articles on molecular genetics in PG have received interest among the ophthalmology community.
ABSTRACT
Aim: The purpose of this study is to establish a normative database of subfoveal choroidal thickness (CT) in healthy young Indians using spectral domain optical coherence tomography (SD OCT). Evaluation and comparison of CT of central serous chorioretinopathy (CSC) and fellow eyes were also performed. Materials and Methods: This was a prospective, cross‑sectional, and observational study. It included 112 normal eyes of 112 healthy volunteers who had no evidence of ocular or systemic disease, 84 CSC eyes with acute, treatment‑naïve CSC, and 69 fellow eyes with no evidence of neurosensory detachment or pigment epithelium detachment on SD OCT. Complete history, examination, and SD OCT were performed in all eyes. Results: The mean age of 81 patients (84 eyes) with CSC was 35.04 ± 8.86 years, 69 fellow eyes was 34.61 ± 8.71 years, and 112 healthy volunteers (112 eyes) was 33.16 ± 9.4 years (P < 0.05). The mean subfoveal CT of CSC eyes was 429 ± 74.18 μ, fellow eyes was 360 ± 57.99 μ, and normal eyes was 301.80 ± 46.59 μ (P < 0.001). Conclusion: CT varies not only with age, axial length, and refractive error but also with races. Therefore, it is important to establish a normative database in a particular population before carrying out further research in diseased states. CT in CSC eyes is significantly thicker than fellow eyes, and CT of fellow eyes is significantly thicker than normal eyes. This reinforces the fact that choroidal permeability is increased in both eyes of patients with CSC.
