Predicting visual recovery in pituitary adenoma patients post-endoscopic endonasal transsphenoidal surgery: Harnessing delta-radiomics of the optic chiasm from MRI. Eur Radiol 2023; 33:7482-7493. [PMID: 37488296 PMCID: PMC10598191 DOI: 10.1007/s00330-023-09963-9] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/26/2022] [Revised: 05/18/2023] [Accepted: 05/23/2023] [Indexed: 07/26/2023]
Abstract
OBJECTIVES To investigate whether morphological changes after surgery and delta-radiomics of the optic chiasm obtained from routine MRI could help predict postoperative visual recovery of pituitary adenoma patients. METHODS A total of 130 pituitary adenoma patients were retrospectively enrolled and divided into the recovery group (n = 87) and non-recovery group (n = 43) according to visual outcome 1 year after endoscopic endonasal transsphenoidal surgery. Morphological parameters of the optic chiasm were measured preoperatively and postoperatively, including chiasmal thickness, deformed angle, and suprasellar extension. Delta-radiomics of the optic chiasm were calculated based on features extracted from preoperative and postoperative coronal T2-weighted images, followed by machine learning modeling using least absolute shrinkage and selection operator wrapped with support vector machine through fivefold cross-validation in the development set. The delta-radiomic model was independently evaluated in the test set, and compared with the combined model that incorporated delta-radiomics, significant clinical and morphological parameters. RESULTS Postoperative morphological changes of the optic chiasm could not significantly be used as predictors for the visual outcome. In contrast, the delta-radiomics model represented good performances in predicting visual recovery, with an AUC of 0.821 in the development set and 0.811 in the independent test set. Moreover, the combined model that incorporated age and delta-radiomics features of the optic chiasm achieved the highest AUC of 0.841 and 0.840 in the development set and independent test set, respectively. CONCLUSIONS Our proposed machine learning models based on delta-radiomics of the optic chiasm can be used to predict postoperative visual recovery of pituitary adenoma patients. CLINICAL RELEVANCE STATEMENT Our delta-radiomics-based models from MRI enable accurate visual recovery predictions in pituitary adenoma patients who underwent endoscopic endonasal transsphenoidal surgery, facilitating better clinical decision-making and ultimately improving patient outcomes. KEY POINTS • Prediction of the postoperative visual outcome for pituitary adenoma patients is important but challenging. • Delta-radiomics of the optic chiasm after surgical decompression represented better prognostic performances compared with its morphological changes. • The proposed machine learning models can serve as novel approaches to predict visual recovery for pituitary adenoma patients in clinical practice.

Abstract
OBJECTIVE Quantitative data on visual outcomes after trans-sphenoidal surgery is lacking in the literature. This study aims to address this by quantitatively assessing visual field outcomes after endoscopic trans-sphenoidal pituitary adenectomy using the capabilities of modern semi-automated kinetic perimetry. METHODS Visual field area (deg2) calculated on perimetry performed before and after surgery was statistically analysed. Functional improvement was assessed against UK driving standards. RESULTS Sixty-four patients (128 eyes) were analysed (May 2016-Nov 2019). I4e and I3e isopter area significantly increased after surgery (p < 0.0001). Of eyes with pre-operative deficits: 80.7% improved and 7.9% worsened; the median amount of improvement was 60% (IQR 6-246%). Median increase in I4e isopter was 2213deg2 (IQR 595-4271deg2) and in I3e isopter 1034 deg2 (IQR 180-2001 deg2). Thirteen out of fifteen (87%) patients with III4e data regained driving eligibility after surgery. Age and extent of resection (EOR) did not correlate with visual improvement. Better pre-operative visual field area correlated with a better post-operative area (p < 0.0001). However, the rate of improvement in the visual field area increased with poorer pre-operative vision (p < 0.0001). CONCLUSIONS A median visual field improvement of 60% may be expected in over 80% of patients. Functionally, a significant proportion of patients can expect to regain driving eligibility. EOR did not impact on visual recovery. When the primary goal of surgery is alleviating visual impairment, optic apparatus decompression without the aim for gross total resection appears a valid strategy. Patients with the worst pre-operative visual field often experience the greatest improvement, and therefore, poor pre-operative vision alone should not preclude surgical intervention.

Abstract
PURPOSE Brain tumors are the leading cause of death from childhood cancer. Although overall survival has improved due to earlier detection, better therapies, and improved surveillance, visual dysfunction and impaired vision-related quality-of-life (VR-QOL) are often unrecognized in children. This project investigated VR-QOL in pediatric brain tumor patients. METHODS We evaluated visual impairment and quality-of-life (QOL) in a quality improvement project at one tertiary care center. Patients ≤ 18, greater than 6 months from diagnosis of brain tumor, excluding intrinsic anterior visual pathway tumors, underwent standardized neuro-ophthalmologic examination. Health-related QOL (HR-QOL) (PedsQL Brain Tumor Module) and VR-QOL questionnaires [CVFQ (Children's Visual Function Questionnaire) in children < 8, and EYE-Q in children 8-18] were obtained from patients and parents. RESULTS Among 77 patients, craniopharyngiomas (n = 16, 21%) and astrocytomas (n = 15, 20%) were the most common tumors. Among 44/77 (57%) visually impaired children, 7 (16%) were legally blind. Eye-Q median score was 3.40 (interquartile range 3.00-3.75), worse than average scores for normal children. Eye-Q score decreased 0.12 with every 0.1 increase in logMAR visual acuity (p < 0.001). Patients who were legally blind had a significantly lower Eye-Q score than those who were not [0.70 vs. 3.44 (p < 0.001)]. Cognitive HR-QOL scores decreased 1.3 for every 0.1 increase in logMAR visual acuity (p = 0.02). CONCLUSIONS Pediatric brain tumor patients' vision, HR-QOL, and VR-QOL were often severely affected even when tumors were considered cured. Visual acuity and legal blindness correlated with VR-QOL. Systematic neuro-ophthalmologic examinations in pediatric primary brain tumor patients are necessary to facilitate early preventative and corrective ophthalmologic interventions.

Abstract
Measuring visual functions such as light and contrast sensitivity, visual acuity, reading speed, and crowding across retinal locations provides visual-field maps (VFMs) that are extremely valuable for detecting and managing eye diseases. Although mapping light sensitivity is a standard glaucoma test, the measurement is often noisy (Keltner et al., 2000). Mapping other visual functions is even more challenging. To improve the precision of light-sensitivity mapping and enable other VFM assessments, we developed a novel hybrid Bayesian adaptive testing framework, the qVFM method. The method combines a global module for preliminary assessment of the VFM's shape and a local module for assessing individual visual-field locations. This study validates the qVFM method in measuring light sensitivity across the visual field. In both simulation and psychophysics studies, we sampled 100 visual-field locations (60° × 60°) and compared the performance of qVFM with the qYN procedure (Lesmes et al., 2015) that measured light sensitivity at each location independently. In the simulations, a simulated observer was tested monocularly for 1,000 runs with 1,200 trials/run, to compare the accuracy and precision of the two methods. In the experiments, data were collected from 12 eyes (six left, six right) of six human subjects. Subjects were cued to report the presence or absence of a target stimulus, with the luminance and location of the target adaptively selected in each trial. Both simulations and a psychological experiment showed that the qVFM method can provide accurate, precise, and efficient mapping of light sensitivity. This method can be extended to map other visual functions, with potential clinical signals for monitoring vision loss, evaluating therapeutic interventions, and developing effective rehabilitation for low vision.

Abstract
PURPOSE The impact of visual acuity (VA) on Health-Related Quality of Life (HRQoL) and the cross-sectional and longitudinal differences in HRQoL during the 11-year follow-up were investigated. The aim was to examine the impact declining vision has on HRQoL and to provide comparable data to facilitate the allocation of health-care resources. METHODS We utilized nationwide health examination surveys carried out by the National Institute for Health and Welfare in 2000 and 2011, providing a representative sampling of the Finnish adult population aged 30 and older. VA was assessed through Snellen E test, and HRQoL scores were evaluated using EQ-5D and 15D questionnaires. Multiple imputations with Markov chain Monte Carlo method was used to utilize the data more effectively. Regression analyses were conducted to assess the impact of declining VA on HRQoL, adjusted for incident comorbidities. RESULTS Lower VA status was associated with significantly lower HRQoL at both time points, most clearly observable below the VA level of 0.5. Declining VA resulted in statistically significant decline in HRQoL during the follow-up, greater with distance than near VA. 15D impairment associated with decline in the distance VA was also clinically meaningful and greater than that associated with any of the examined comorbidities. CONCLUSIONS HRQoL was significantly and meaningfully impaired even before the threshold of severe vision loss or blindness was reached. The results encourage the improvement of available treatment options aiming to postpone the onset of visual impairment or declining VA, to maintain better quality of life among the population.

Abstract
PURPOSE Patients with pituitary adenomas often present with visual deficits. While the aim of endoscopic endonasal transsphenoidal surgery (EETS) is to improve these deficits, permanent worsening is a possible outcome. The aim of this meta-analysis was to evaluate the effect of EETS for pituitary adenomas on visual outcomes. METHODS A meta-analysis was conducted according to the PRISMA guidelines. Pooled prevalence was calculated for complete recovery, improvement, and deterioration of visual field deficits, visual acuity and unspecified visual function in fixed- and random-effect models, including assessment of heterogeneity (I2) and publication bias (Begg's test). RESULTS Out of 2636 articles, 35 case series were included in the meta-analysis. Results are described for fixed-effect models. For patients with impaired visual acuity, only one study reported complete recovery (27.2%). Pooled prevalence for improvement was 67.5% (95% CI = 59.1-75.0%), but with considerable heterogeneity (I2: 86.0%), and 4.50% (95% CI = 1.80-10.8%) for patients experiencing deterioration. For patients with visual field deficits, the prevalence was 40.4% (95% CI = 34.8-46.3%) for complete recovery, 80.8% (95% CI = 77.7-83.6%) for improvement, and 2.3% (95% CI = 1.1-4.7%) for deterioration. For the unspecified visual outcomes, pooled prevalence of complete recovery was 32.9% (95% CI: 28.5-37.7%), but with considerable heterogeneity (I2 = 84.2%). The prevalence was 80.9% (95% CI = 77.9-83.6) for improvement and 2.00% (95% CI = 1.10-3.40%) for deterioration. Random-effect models yielded similar results. Publication bias was non-significant for all the outcomes. CONCLUSION While visual deficits improved after EETS in the majority of patients, complete recovery was only achieved in less than half of the patients and some patients even suffered from visual deterioration.

Abstract
Children with optic pathway gliomas (OPGs) frequently experience vision loss from their tumors. Most pediatric OPG research has focused on radiographic and visual outcomes, yet the impact of vision loss on quality of life (QOL) in children with OPGs has not been studied. The present study prospectively recruited children ≤ 10 years of age with sporadic or neurofibromatosis type 1 (NF1)-related OPGs. Vision specific QOL was assessed by parent proxy using the Children's Visual Function Questionnaire (CVFQ), and scores were analyzed according to magnitude of visual acuity (VA) loss and presence of visual field (VF) loss. Thirty-six subjects completed the study (53 % female) with median age of 4.6 years. Children with mild, moderate and severe vision loss have lower CVFQ subscale scores, indicating a lower vision specific QOL, compared to those with normal vision. Lower Competence scores were noted in participants with more profound vision loss (p < 0.05), reflecting a decreased ability to complete activities of daily living (e.g., feeding, grooming). Children with two visually impaired eyes were rated as having greater difficulty with social interactions and pleasurable activities (Personality subscale, p = 0.039) compared to those with only one impaired eye. In summary, our findings demonstrate that children with vision loss secondary to their OPG have a decreased vision specific QOL compared to those with normal vision. Measuring vision specific QOL may be considered a meaningful secondary outcome measure for pediatric OPG clinical trials.

Abstract
Visual field assessment is important in the evaluation of lesions involving the visual pathways and should be performed at baseline and periodically in the follow-up. Standard automated perimetry has been shown to be adequate in neuro-ophthalmic practise and is now the technique of choice for a majority of practitioners. Goldman kinetic visual fields are useful for patients with severe visual and neurologic deficits and patients with peripheral visual field defects. Visual fields are useful in monitoring progression or recurrence of disease and guide treatment for conditions such as idiopathic intracranial hypertension (IIH), optic neuropathy from multiple sclerosis, pituitary adenomas, and other sellar lesions. They are used as screening tools for toxic optic neuropathy from medications such as ethambutol and vigabatrin. Visual field defects can adversely affect activities of daily living such as personal hygiene, reading, and driving and should be taken into consideration when planning rehabilitation strategies. Visual field testing must be performed in all patients with lesions of the visual pathway.

Abstract
PURPOSE OF REVIEW Quality of life (QoL) is impaired in patients with pituitary tumors, even after biochemical cure. However, it is not usually assessed in daily practice. The aim of this study is to highlight recent findings on QoL in the different types of pituitary adenomas and hypopituitarism. RECENT FINDINGS Patients with acromegaly or Cushing's syndrome have the greatest impairment of QoL, and concomitant hypopituitarism worsens it further. The use of disease-generated QoL questionnaires allows dimensions specifically affected in that disease to be addressed and these dimensions are more sensitive to change after successful therapy; in some cases, improvement in patients' sense of well-being has been shown despite no hormonal change, indicating that evaluation of QoL is not such a soft end-point as thought by some. SUMMARY Systematic evaluation of QoL in patients with pituitary diseases provides information not always contemplated by hormonal and routine clinical evaluation; this allows detection of not often contemplated health problems, which may then be approached and treated, improving the care provided to these patients.
