Retinal biomarkers for visual prognosis in pituitary surgery: a narrative review.
Review in Pituitary, 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
backgroundPituitary macroadenomas frequently cause visual impairment through compression of the optic chiasm, and endoscopic transsphenoidal surgery remains the standard of care for achieving decompression. Despite favorable surgical outcomes in many patients, visual recovery following chiasmal decompression is heterogeneous and difficult to predict using conventional visual field testing alone. Over the past two decades, optical coherence tomography (OCT) has emerged as a noninvasive retinal imaging modality capable of quantifying structural changes in the retinal nerve fiber layer (RNFL) and macular ganglion cell complex (GCC) with micrometer-level resolution. A growing body of evidence suggests that preoperative RNFL thinning and GCC loss reflect irreversible axonal degeneration from chronic chiasmal compression and that these measurements carry prognostic value for postoperative visual outcomes.
objectiveTo examine the current evidence linking preoperative retinal OCT parameters to visual recovery following transsphenoidal surgery for pituitary macroadenomas.
methodsThis narrative review evaluates published studies investigating the association between preoperative OCT-derived retinal structural measurements and postoperative visual outcomes in patients undergoing transsphenoidal surgery for pituitary macroadenomas.
resultsThe available evidence suggests that preoperative RNFL and GCC measurements may serve as useful biomarkers of irreversible optic pathway injury and predictors of postoperative visual recovery.
conclusionsWe discuss the pathophysiological rationale, summarize key clinical studies, consider the limitations of existing evidence, and outline the clinical implications for a multidisciplinary approach that integrates neurosurgical and ophthalmic expertise in preoperative assessment.
