1 · What the graph read from it

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.

2 · The registry

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

backgroundFibrin membrane-induced pupillary block (FMPB) and subsequent glaucoma are rare complications in humans after intraocular surgery, typically managed with neodymium-doped yttrium aluminium garnet (Nd:YAG) laser iridotomy. While this condition is infrequently reported in dogs, it can occur after cataract surgery, with existing treatments being more invasive and less established than in humans.

objectiveTo evaluate the feasibility and clinical outcomes of Nd:YAG laser membranotomy as a treatment for FMPB in dogs.

methodsTwo dogs presenting with post-cataract surgery complications, including FMPB and iris bombé, underwent Nd:YAG laser membranotomy. Treatment included preoperative anti-inflammatory and anti-glaucoma therapy, followed by laser procedures targeting fibrin membranes.

resultsBoth cases showed immediate relief of pupillary block and reduction of intraocular pressure (IOP). Despite complications including transient uveitis and corneal oedema, Nd:YAG laser treatment effectively resolved FMPB and maintained IOP stability. Vision was preserved in one case, while gradual vision loss occurred in the other due to pre-existing and procedure-related complications.

conclusionNd:YAG laser membranotomy may offer a minimally invasive option for managing FMPB in some dogs. It may also be a promising alternative to more invasive procedures when appropriate postoperative care is ensured.
