Partial orbital lobe dacryoadenectomy for refractory epiphora.
Article in Indian 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
purposeTo evaluate the efficacy of partial orbital lobe dacryoadenectomy (POLD) in patients with refractory epiphora.
designProspective interventional study.
settingTertiary eye care institute. STUDY POPULATION: Consecutive patients with refractory epiphora due to proximal lacrimal outflow system obstruction, multiple failed dacryocystorhinostomy, and postdacryocystectomy. All patients underwent preoperative assessment with Munk score, Schirmer-I Score, tear breakup time, corneal fluorescein staining, anterior segment OCT (AS-OCT), and CT scans of the orbit.
interventionPartial removal of the lacrimal gland orbital lobe under local anesthesia.
main outcome measureReduction in epiphora. Objective and subjective evaluation was repeated at postoperative 1-week, 1-month, and 3-month visits.
resultsOut of 17 patients enrolled, one had congenital punctal agenesis, three had acquired punctal effacement, and 13 had proximal bicanalicular obstruction. The mean age was 48.8 ± 18.6 years. All patients underwent POLD, with removal of 50-60% of the orbital lobe of the lacrimal gland. The mean follow-up duration was 5.7 months. At 3-month follow-up visit, the average reduction in Munk score was 60%, the average reduction in Schirmer-I value was 35.2%, and the average reduction in tear film height on AS-OCT was 35.9% (all statistically significant, P < 0.05), from the initial visit. None of the patients developed signs and symptoms of dry eye disease.
conclusionPOLD is an effective and safe procedure for patients with refractory epiphora in the short term. Further studies are needed to establish efficacy in the long term.
