Comparative analysis of pre-operative findings and post-operative outcomes in primary and secondary macular holes at a tertiary eye hospital in South India.
Article in International journal of retina and vitreous, 2024. 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
purposeThis study aimed to compare demographics, clinical characteristics, and post-surgical outcomes between idiopathic and secondary full-thickness macular holes (MHs).
methodsA retrospective analysis of 348 eyes from 339 patients treated between June 2017 and December 2023 was conducted. The study included both idiopathic and secondary MHs, excluding cases where surgery was not performed or lacked sufficient follow-up. Demographic data, visual acuity (VA), ocular characteristics, and optical coherence tomography measurements were analyzed.
resultsIdiopathic MHs were identified in 308 eyes (89%), and secondary MHs in 40 eyes (11%). Idiopathic MH patients were older (mean age: 68.26 vs. 60.13 years; p = 0.001) and more commonly female (63% vs. 40%; p = 0.005). Post-surgical closure was achieved in 86% of all MHs, with a median VA improvement of 15 ETDRS letters (3 Snellen lines). However, secondary MHs had a lower closure rate (67% vs. 89%, p = 0.001) and less VA improvement (2 lines vs. 3 lines, p = 0.001) compared to idiopathic MHs. Significant differences in maximal basal diameter and diameter hole index were noted between the groups.
conclusionsSecondary MHs, accounting for 11% of surgical cases, show poorer anatomical and visual outcomes than idiopathic MHs. Despite lower success rates, early surgical intervention in secondary MHs is recommended to enhance outcomes. Differentiating between idiopathic and secondary MHs is crucial for optimal management.
