Summary: This study reports the results of a clinical trial on patients with acute non-arteritic optic neuropathy (NA-AION) treated with an intravitreal injection of allogeneic bone marrow-derived mesenchymal stem cells (BM-MSCs). The study found that the intravitreal application of allogeneic BM-MSCs appeared to be well tolerated and resulted in visual improvement in some patients.

Summary: NAION is a major cause of permanent visual impairment in individuals over 50 years old, with no established treatment plan. MSC-exosome shows potential as a therapeutic approach by promoting angiogenesis and neuro-regeneration. Questions regarding dosing, injection frequency, and treatment duration need to be addressed before clinical testing.

Summary: Current management of glaucomatous optic neuropathy is limited to intraocular pressure control. Neuroglobin (Ngb) is an endogenous neuroprotectant expressed in neurons and astrocytes. This study found that intravitreal Ngb treatment reduced thinning of the peripapillary minimum rim width, retinal nerve fiber layer thickness, and optic nerve head cupping in a primate model of glaucoma.

Summary: Traumatic optic neuropathy (TON) causes loss of retinal ganglion cells (RGCs) and their axonal fibers, leading to visual insufficiency. This study investigated the potential neuroprotective effects of Huperzine A (HupA) extracted from a Chinese herb and its ability to enhance neuronal regeneration after optic nerve crush (ONC). The study found that intravitreal injection of HupA promoted RGC survival and axonal regeneration after ONC, through the mTOR pathway, and these effects were blocked by rapamycin. Therefore, HupA shows promise for the clinical treatment of traumatic optic neuropathy.

Summary: This study aimed to investigate the safety and effectiveness of intravitreal aflibercept in patients with acute nonarteritic anterior ischemic optic neuropathy (NAION). The results showed that intravitreal aflibercept significantly improved visual acuity and resolved disc edema in patients with acute NAION, suggesting it may be an alternative treatment. However, further large-scale investigations are needed to evaluate the long-term therapeutic benefit and safety.

Summary: The aim of this study was to investigate the frequency and intensity of leukoaraiosis (LA) in symptomatic patients compared to asymptomatic subjects, and its association with soluble tumor necrosis factor-like weak inducer of apoptosis (sTWEAK). The results showed a higher prevalence and intensity of LA in symptomatic patients, and a significant correlation between LA degree and sTWEAK levels.

Summary: The study aimed to evaluate the molecules related to oxidative stress, inflammation, angiogenesis, and apoptosis in patients with proliferative diabetic retinopathy (PDR) and diabetic macular edema (DME). By investigating their correlation in the plasma and vitreous body, as well as examining ophthalmological examination data, the study found that oxidative stress and inflammation were increased in the plasma and vitreous samples from patients with PDR/DME, while antioxidant capacity was decreased. The study suggests that exploring the relationship between these potential biomarkers in the plasma and vitreous may help detect early molecular changes in PDR/DME and monitor therapeutic outcomes.

Summary: The objective of this study was to compare the impact of glucose-lowering drugs on peripheral nerve and kidney function in prediabetes. The results showed that the use of metformin alone, linagliptin alone, or the combination of both reduced the risk of small fiber peripheral neuropathy and slowed down the decrease in estimated glomerular filtration rate compared to the placebo. These findings suggest that treatment with metformin and linagliptin, either alone or in combination, can effectively protect prediabetes patients from developing peripheral nerve diseases and maintain kidney function.

Summary: This study aimed to investigate whether the quantification of microaneurysms (MAs), hemorrhages (Hmas), and hard exudates (HEs) in the central retinal field could predict the severity of diabetic retinopathy (DR). The results showed that the number of MAs, Hmas, and HEs increased as the severity of DR progressed. These findings suggest that analyzing retinal lesions in the central field can provide valuable information on the severity level of DR and serve as a clinical tool for assessing DR grading in routine eyecare.

Summary: The study evaluated the agreement of pRNFL and FT measurements among different SD-OCT instruments in MS patients and healthy controls. MS eyes with a history of ON showed thinner pRNFL and FT, while healthy subjects and MS eyes without ON had similar thickness. Devices like PRIMUS and CIRRUS OCT showed better agreement compared to 3D OCT.
