Anxiety disorder is a common emotional disorder.Ophthalmic diseases, which can cause ocular pain, discomfort, and irreversible visual impairment, not only lead to a deterioration in patients' quality of life but also give rise to mental health issues, including anxiety and depression.Numerous studies have indicated that a substantial number of patients with eye diseases frequently exhibit anxiety symptoms, and the prevalence rate is notably higher compared to that of the general population.This relationship is bidirectional.On the one hand, factors associated with eye diseases, such as vision loss, changes in appearance, economic burden, and reduced quality of life, can trigger or exacerbate anxiety.On the other hand, anxiety can accelerate the onset and progression of certain eye diseases, such as dry eye, pseudo-myopia and glaucoma by influencing neurotransmitter function, the autonomic nervous system, and the hypothalamus-pituitary-adrenal axis.The alleviation of eye conditions necessitates not only active treatment of the disease itself, but also maintaining a healthy psychological state.This review reviews the reciprocal relationship between various eye diseases, including dry eye, glaucoma, diabetic retinopathy, and age-related macular degeneration, and anxiety to more clearly elucidate their mutual influence, provide guidance for integrated psychological treatment in the clinical management of eye diseases and raise ophthalmologists' awareness of the significance of mental health in disease treatment.

Objective To compare ferroptosis characteristics and motor dysfunction across different mouse models of Parkinson's disease(PD).Methods Animal models of PD were divided into five groups:the control group,sham-operated group,6-hydroxydopamine(6-OHDA)group,1-methyl-4-phenyl-1,2,3,6-tetrahydropyri-dine(MPTP)group,and lipopolysaccharide(LPS)group.Differences in ferroptosis-related features and motor dysfunction across these groups were evaluated through behavioral observation,histopathological examination,protein analysis,and assessment of lipid peroxidation and oxidative stress levels.Results In all three model groups,the number of TH-positive neurons in the substantia nigra on the lesioned side was significantly reduced,accompanied by evident neuronal degeneration and a marked decrease in Nissl bodies.Behavioral assessments revealed that the 6-OHDA group displayed the most severe motor deficits.In the substantia nigra,FTH1 protein expression was significantly downregulated in the 6-OHDA,LPS,and MPTP groups(P<0.01,P<0.05,P<0.01),respectively,while GPX4 expression was also reduced(P<0.001,P<0.001,P<0.01).Malondialdehyde(MDA)levels were significantly elevated in both the 6-OHDA and MPTP groups(P<0.05,P<0.05).Glutathione(GSH)assays demonstrated markedly reduced levels in the 6-OHDA,MPTP,and LPS groups(P<0.01,P<0.001,P<0.001).Reactive oxygen species(ROS)detection revealed a significant increase in the MPTP and LPS groups(P<0.05,P<0.05).Conclusion The 6-OHDA model is well suited for studying PD-related behaviors and the underlying mechanisms of motor symptoms,the MPTP model is particularly effective for investigating the ferroptosis pathway,and the LPS model serves as a valuable complement for research on neuroinflammation mechanisms.
