The Potential Role of Vitamin D in the Pterygium Pathophysiology-A Possible New Therapeutic Perspective and Narrative Review.
Review in Journal of clinical medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Vitamin D plays a vital role in human physiology, including a crucial role in regulating bone metabolism and various extra-skeletal effects. Calcitriol exerts anti-inflammatory effects on monocytes and macrophages by increasing IL-10 production and decreasing the production of proinflammatory IL-1β, IL-6, tumor necrosis factor-α (TNF-α), receptor activator of nuclear factor kappa-Β ligand (RANKL), and cyclo-oxygenase-2 (COX-2). In addition, calcitriol also exerts important effects on adaptive immunity by downregulating MHC-II class and co-stimulatory molecules on antigen-presenting cells, but it also directly affects T lymphocytes. In multiple studies, the influence of vitamin D on eye diseases, including corneal diseases, has been demonstrated. Adequate vitamin D supplementation in patients with dry eye significantly improves tear quality and consequently heals the epithelial cells of the ocular surface. Pterygium is a fibrovascular growth of conjunctival tissue that histologically consists of superficial conjunctival epithelium and an underlying fibrovascular layer. The prevalence of pterygium depends on the region. In zones closer to the equator-"pterygium zone", it is up to 22%, and outside of them it can be even less than 2%. While UV radiation is recognized as a primary risk factor, other factors, including vitamin D, may influence its development. This review aims to summarize the effects of vitamin D on the pathophysiological mechanism of pterygium and its possible therapeutic impact. Current research suggests that vitamin D is protective through its immunomodulatory and anti-inflammatory properties. Finally, there is still insufficient evidence of the therapeutic benefit of vitamin D in pterygium, and future large-scale randomized controlled studies are needed to elucidate the exact role of vitamin D in pterygium onset and recurrence as well as its potential therapeutic benefit.
