Prophylactic effect of topical silica nanoparticles as a novel antineovascularization agent for inhibiting corneal neovascularization following chemical burn.
Article in Advanced biomedical research, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers.
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
backgroundAngiogenesis-related corneal blindness includes the spectrum of corneal diseases that are caused by pathological angiogenesis, leading to untoward visual impairment. The purpose of this study was to investigate the antineovascularization effect of topical silica nanoparticles (SiNPs) in inhibiting chemical-burn-induced corneal neovascularization. MATERIALS AND
methodsA total number of 20 corneas of 10 Wistar Albino rats were included in this study. Silver nitrate cauterization was pressed to the central cornea for 5 s to induce corneal neovascularization. They were randomly allocated to case and control groups (ten eyes in each group). SiNPs were synthesized by the reverse microemulsion method. SiNPs drop 1 mg/ml was started in ten eyes and artificial tear drop was started in the control group (ten eyes) immediately after chemical cauterization. Video-based photography was performed before and after treatment. Corneal image analysis was performed on each cornea using an image analysis software program. All rats were euthanized and the eyes were sent for histopathologic examinations14 days after chemical cauterization.
resultsScanning electron microscopy (SEM) images showed spherical-shaped particles. The mean size and polydispersity index of prepared SiNPs were 30.1 ± 5.6 nm and 0.254 ± 0.11, respectively. Fourteen days after chemical cauterization, the mean vascularized corneal area was 21% of total corneal area in the case group and 85% in the control group (P < 0.05). The control group revealed more extensive intrastromal vascularization compared with the case group in histopathologic examinations (P < 0.05).
conclusionsSiNPs is an effective modality for inhibiting corneal neovascularization following chemical burn in an experimental model. Further investigations are suggested for evaluation of its safety and efficacy in human eyes.
