Laser photocoagulation improves the transduction efficiency of lentivirus vectors injected intravitreally.
Article in International journal of ophthalmology, 2026. 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
aimTo evaluate the effect of laser photocoagulation on transfection efficiency of lentivirus (LV) vectors injected intravitreally.
methodsThe rat retina was photocoagulated prior to intravitreal injection of LV vectors encoding red fluorescent protein. Rats given intravitreal injection or photocoagulation alone served as controls. The transduction efficiency was analyzed by fundus angiography, histopathology, and immunofluorescence staining. Potential adverse effect of laser photocoagulation was evaluated in choroid flat mounts by observing the morphology of retinal pigment epithelium (RPE) that formed the outer blood-retina barrier.
resultsLaser photocoagulation enhanced the retinal area transduced by LV vectors in fundus images and increased the maximum transduction thickness in histopathological sections. Choroid flat mounts showed the RPE transduced by LV vectors maintained normal morphology.
conclusionLaser photocoagulation improves the transduction efficiency of LV vectors injected intravitreally, identifying this as a promising gene therapy strategy for inherited retinal dystrophies caused by gene mutations in RPE and photoreceptor cells.
