Prognostic factors in fluid-gas exchange after primary idiopathic macular hole surgery.
Article in International ophthalmology, 2022. 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
purposeThis retrospective study aimed to evaluate the prognostic factors associated with the success of fluid-gas exchange in patients who had undergone failed primary idiopathic macular hole (IMH) surgery.
methodsIn total, 19 eyes of 19 patients with failed IMH surgery who then underwent fluid-gas exchange were included. Of those, 18 eyes had macular hole (MH) closure (successful, 15 eyes; unsuccessful, 3 eyes). Demographics, pre-operative characteristics, and pre-procedural characteristics were assessed. The patients were divided into successful (U or V-type closure) and unsuccessful groups (W-type or unclosed), following fluid-gas exchange. One eye was unclosed after fluid-gas exchange; therefore, this patient underwent additional vitrectomy for MH closure (unsuccessful).
resultsThe outcomes of the fluid-gas exchange were categorized as unclosed or as U-type, V-type, or W-type closure. None of the patients experienced complications after the procedure. The successful group showed a significantly lower pre-operative and pre-procedural minimum diameter, base diameter, and macular hole volume, and higher pre-operative and pre-procedural macular hole index, hole form factor, and tractional hole index values. Moreover, a better visual prognosis was observed in the successful group.
conclusionThese findings suggest that indices predicting favorable results of primary surgery for IMH are useful for predicting the success of fluid-gas exchange in patients with failed primary MH surgery.
