Purpose: To discriminate between compressive optic neuropathy with glaucoma-like cupping (GL-CON) and glaucomatous optic neuropathy (GON) by comparing the peripapillary retinal nerve fiber layer (pRNFL) thickness and retinal microvasculature using optical coherence tomography (OCT) and optical coherence tomography angiography (OCTA).
Methods: In this retrospective cross-sectional study, OCT scans were performed on 28 eyes of GL-CON, 34 eyes of GON, and 41control eyes to determine the pRNFL thickness, ganglion cell complex thickness, and cup/disc ratio. OCTA scans were conducted for 12 eyes of GL-CON, 15 eyes of GON, and 15 control eyes to measure the vessel density of the peripapillary and macular areas.
Aims: This study aimed to investigate the associations among retinal vessel density (RVD), neuroimaging features and cognitive impairment in patients with sporadic cerebral small vessel disease (CSVD).
Methods: This was a prospective observational study. A total of forty-nine patients with CSVD were recruited.
Pituitary adenomas are known to cause optic chiasmal compression leading to visual field (VF) defects. Herein, we analysed the factors influencing early VF recovery following transsphenoidal surgery and explored the significance of retinal vessel density parameters in predicting prognoses. We collected data of 50 patients with pituitary adenoma and an abnormal VF prior to surgery.

- The study focuses on the relationship between retinal nerve fiber layer (RNFL) thickness, measured via optical coherence tomography (OCT), and clinical symptoms in Alzheimer's disease (AD) patients.
- Out of 96 patients, 54.4% showed reduced RNFL thickness, which was significantly correlated with poorer performance in cognitive functions like memory, language, and attention.
- Lower RNFL thickness also indicated a decline in activities of daily living, suggesting that RNFL thickness could serve as a potential indicator of cognitive decline in AD patients, warranting further research.
BACKGROUND The aim of this study was to compare the differences in macular ganglion cell complex (GCC) and peripapillary retinal nerve fiber layer (pRNFL) in child and adult patients with primary craniopharyngioma by Fourier-domain optical coherence tomography (FD-OCT) and to evaluate their significance in the diagnosis of primary craniopharyngioma. MATERIAL AND METHODS Ninety-six participants were divided into 3 groups: 32 in the child craniopharyngioma group (CCG) and 32 in the adult craniopharyngioma group (ACG) who were treated in Beijing Tiantan Hospital between November 2013 and October 2014, and 32 in the normal group (NG). All subjects were scanned by FD-OCT to map GCC and pRNFL thicknesses.

Methods: Retrospective case series study. The clinical data of 34 eyes from 17 patients with children craniopharyngioma treated at the affiliated Beijing Tiantan Hospital, Capital Medical University from September 2011 to May 2012 were collected.
Objectives: To analyze the differences and correlation between the ganglion cell complex (GCC), peripapillary retinal nerve fiber layer (pRNFL) and mean deviation (MD), mean sensitivity (MS) of saddle area tumor patients, and to evaluate the feasibility of using OCT to diagnose the visual pathway damage of saddle area tumor patients.
Methods: It was a case-control study. One hundred and eighty-eight normal persons and 279 saddle area tumor patients treated in Beijing Tiantan hospital, from November 2010 to June 2011, were recruited; the saddle area tumor patients were diagnosed by surgical sample pathological analysis.
Purpose: To examine frequency and associated factors of glaucoma-like appearance of the optic nerve head in patients with intrasellar, suprasellar or parasellar tumours.
Methods: This retrospective clinical observational study included patients who were consecutively treated for intrasellar tumours (n = 143), suprasellar tumours (n = 321), parasellar tumours (n = 36) or retrosellar tumour (n = 1), and all of whom had undergone fundus photography and full-threshold visual field examination. The tumour spectrum included 336 pituitary gland tumours, 32 meningiomas, 89 craniopharyngiomas, 9 chiasmal gliomas and 35 other types of tumours or lesions.
