Novel therapeutic strategies to restore vision in ocular hypotony (STRETCH): results from a prospective pilot series.
Article in The British 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
BACKGROUND/
aimsTo report visual and anatomical outcomes following intravitreal hydroxypropylmethylcellulose (HPMC) for the treatment of chronic structural hypotony.
methodsThis study is a prospective interventional case series. Eight patients with chronic structural hypotony for more than 3 months, defined by an intraocular pressure (IOP) of <6.5 mm Hg. All patients had evidence of visual potential, clear cornea and a clear visual axis.Patients received multiple intravitreal HPMC injections (70 µL-1400 µL), administered every 2-4 weeks until either pre-morbid axial length was achieved, an IOP of 10-15 mm Hg was sustained for 4 weeks without signs of hypotony, or axial length of the contralateral eye was reached. They were followed up for 12 months after the first intravitreal injection.
resultsBest corrected visual acuity (BCVA) logarithm of the minimum angle of resolution (LogMAR) improved in 87.5% of eyes, with one eye remaining stable. The initial BCVA range was 0.3-1.7 LogMAR, and the final range was 0.1-1.6 LogMAR. IOP increased in 87.5% of eyes, from an initial range of 1-5 mm Hg to 3-23 mm Hg. Axial length increased in 75% of eyes, with a median increase of 1 mm (range 0.6-2.9 mm).Two adverse events occurred: uveitis flare-ups leading to loss of HPMC clarity in two eyes, managed with topical and intravitreal steroids, and two cases of temporary vision loss post-injection, resolved after paracentesis.
conclusionThis is the first case series to use a structured protocol for intravitreal HPMC in chronic hypotony management. The treatment improved vision and restored ocular anatomy, showing promise for managing structural hypotony in eyes with visual potential.
