Focal choroidal excavation and choroidal neovascular membrane following sildenafil intake.
Article in Digital journal of ophthalmology : DJO, 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
Sildenafil citrate is widely abused as a recreational drug. The ocular side effects of this drug are often overlooked, because they tend to be mild and transient. Commonly reported side effects include light sensitivity and dyschromatopsia resulting in impairment of blue-green discrimination. We present a rare occurrence of a focal choroidal excavation (FCE) in a healthy 34-year-old Asian Indian man after sildenafil intake. Sudden diminution of vision was noted a day after taking 50 mg/day sildenafil for 3 consecutive days. An FCE was seen on the optical coherence tomography in the left eye, with visual acuity of 20/30. Choroidal and outer retinal layers were disturbed superior to the fovea. Color vision disturbance was also noted. A choroidal neovascular membrane developed after 8 months, which was treated with ranibizumab injection. Final visual acuity was 20/80, due to macular scarring in the left eye. Sildenafil has been shown to cause choroidal thickening. We hypothesize that the sudden turgescence of the choroid might have led to the FCE.
