Effect of retrobulbar prostaglandin analog injection on orbital fat in rats.
Article in International ophthalmology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
purposePeriorbital fat atrophy is a known side effect of topical prostaglandin analogs (PA). This side effect may have implications in the treatment of diseases like thyroid orbitopathy. In this in vivo study we aimed to evaluate the effects of retrobulbar injection of three different PAs on orbital fat.
methodsEighteen adult male Wistar-albino rats were divided into three groups of six animals. 0.1 ml of 0.03% bimatoprost, 0.005% latanoprost, or 0.005% travoprost was injected into the right orbits and saline was injected into the left orbits, as controls. Both orbits were exenterated after 3 weeks. Histological cross-sections were analyzed using ImageJ image analysis software. Intraconal adipocyte density was calculated.
resultsThere was no significant difference in the adipocyte density between the PA injected orbits and the control side in each of the three groups. When calculations from all three groups were analyzed together, again the difference in the adipocyte density between the PA injected orbits and the control side was not significant.
conclusionNo significant fat atrophy was noted in this rat model three weeks after retrobulbar injection of PAs. To evaluate retrobulbar injection of PA as a potential therapy for orbital diseases with fat proliferation, in vivo studies in different animal models, higher concentrations of PA, or longer follow-up duration are required.
