Background: Since it has been shown that photocoagulation is indicated in patients with diabetic macular edema, quantitative and objective assessment of retinal thickness is of clinical importance.
Methods: A laser slit beam was projected on the retina and scanned across a 2 x 2 mm retinal area in 200 msec. Nine type 1 and 2 diabetic patients without funduscopically and photographically visible diabetic retinopathy and 10 healthy controls were scanned with the RTA. The intraindividual and interindividual variabilities of the RTA were determined.
Results: The intraindividual and interindividual variability was 5 microm and 15 microm, respectively. The mean value of the mean foveal thickness (MFT) and perifoveal retinal thickness (PFT) in the 10 healthy controls was 152 +/- 15 microm and 175 +/- 14 microm, respectively, and 181 +/- 26 microm and 191 +/- 27 microm, respectively, in the group of nine diabetics without signs of diabetic retinopathy. The MFT in the group of diabetic patients was significantly (P < 0.001) larger than in the control groups.
Conclusion: Retinal thickness in diabetic patients without diabetic retinopathy was increased in all measurements in comparison with the findings in healthy subjects. Retinal thickness measurements with the RTA could possibly detect early signs of diabetic retinopathy before funduscopic and photographic signs are visible and may be helpful in guiding treatment.

Purpose: Changes associated with Alzheimer's disease (AD) may have measurable effects on the retina, which may facilitate early detection due to the eye's accessibility. Retinal pathology and the regulation of serine racemase (SR) were investigated in the retinas of APP(SW)/PS1(∆E9) mice.
Methods: SR in the retinas and the content of D-serine in the aqueous humor were analyzed.

Background: Previous investigations on optical coherence tomography (OCT) in multiple sclerosis (MS) focused on generalizable macular and peri-papillary regions without considering the anatomic variations of the retinal layer thickness.
Objective: This study aimed to assess the utility of parafoveal retinal layer thickness measured by OCT, underscoring its relationships with clinical outcomes in MS.
Methods: In this cross-sectional study, 214 people with MS (pwMS) and 57 age- and sex-matched healthy controls (HCs) were enrolled.

Background: Idiopathic intracranial hypertension (IIH) is increasingly prevalent, yet longitudinal outcome data are scarce. This study aimed to characterise demographic and longitudinal clinical changes in a cohort of patients with IIH.
Methods: Retrospective cohort analysis on adult patients diagnosed with IIH (Friedman criteria) enrolled in the neuro-ophthalmology database (NODE) across two tertiary centres.

Purpose: To evaluate the posterior scleral stiffness of different regions in high myopic eyes and to explore its associations with macular choroidal and peripapillary retinal nerve fiber layer (pRNFL) thickness and vasculature.
Methods: Thirty subjects with high myopic eyes and 30 subjects with low myopic eyes were included in this study. The elastic modulus of the macular and peripapillary sclera at the temporal, nasal, superior and inferior regions were determined via shear wave elastography (SWE).

Department of Medical and Surgical Sciences, University of Foggia, 71122, Foggia, Italy.
Background: Multiple sclerosis (MS) involves a complex interplay between immune-mediated inflammation and neurodegeneration. Recent advances in biomarker research have provided new insights into the molecular underpinnings of MS, including ferritin, neurogranin, Triggering Receptor Expressed on Myeloid cells 2 (TREM2), and neurofilaments light chain.
Objectives: This pilot study aims to investigate the levels of these biomarkers in the cerebrospinal fluid (CSF) of MS patients and explore their associations with clinical, cognitive, and optical coherence tomography (OCT) parameters.
