Post-vitrectomy Macular Edema: Shedding Light on Incidence and Risk Factors.
Review in Ophthalmology and therapy, 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
Post-surgical macular edema is a common cause of delayed visual recovery. Although its occurrence after cataract surgery is well known, the specifics on post-vitrectomy macular edema (PVME) are less readily available in the recent literature. This narrative review identifies a wide-ranging incidence due to heterogeneous surgical indications, study designs, and lack of diagnostic standards in the current literature. PVME requiring pharmacological treatment ranges from 2.0 to 27.3%. Higher rates of macular edema are encountered after vitrectomy for retinal detachment, retained lens fragments, and epiretinal membranes. The intraretinal cystic changes after epiretinal membrane removal, however, often represent remnants of tractional disease, rather than true macular edema. This review elaborates on several patient-related and surgical risk factors, mostly in retinal detachment surgery. Predisposing factors are redetachment, proliferative vitreoretinopathy, silicone oil tamponades, extensive retinopexy, and macular involvement in cases with a retinal detachment. Patients who undergo procedures for macular holes, vitreous floaters, and secondary lens implantation appear less susceptible to developing PVME. Furthermore, higher rates of PVME are seen after crystalline lens removal, both in combined phacoemulsification-vitrectomy and when cataract surgery is performed after the vitrectomy. Additional research should lead to improved risk assessment and a reduced burden of this clinical issue.
