Objective: To investigate the potential regional homogeneity (ReHo) brain activity changes in patients with corneal ulcer (CU) and their possible relationship with clinical symptoms.
Materials And Methods: Forty patients with CU (26 men and 14 women), and 40 healthy controls (HCs) (26 men and 14 women) closely matched in age, sex, and weight underwent resting-state functional MRI scans, respectively. The ReHo method was applied to evaluate synchronous neural activity changes. Receiver operating characteristic curve (ROC curve) was used to show high test-retest stability and high degree of sensitivity and specificity. We utilized the correlation analysis to calculate the relationship between the average ReHo signal values in different brain areas and the clinical symptoms in CU patients.
Results: Compared with the HCs, CU patients had significantly increased ReHo values in right cerebellum posterior lobe, left cerebellum posterior lobe, left inferior temporal gyrus, right lingual gyrus, left middle frontal gyrus, left angular gyrus, left cingulate gyrus, right angular gyrus and bilateral superior frontal gyrus, and decreased ReHo values in right anterior cingulate and left precentral gyrus. ROC curve analysis of each brain regions showed the accuracy of AUC was perfect except the right cerebellum posterior lobe. Nevertheless, there was no clear evidence of prominent relevance between the average ReHo values in brain areas and the clinical symptoms.
Conclusion: Corneal ulcer caused dysfunctional adaption in different brain areas, which including relatively increased values and decreased values. This finding may help us take a further step in exploring the underlying pathologic mechanisms of CU.

Objectives: To investigate the pathogenicity of feline herpesvirus-1 (FHV-1) to the cornea, FHV-1 strains isolated from feline eyes with dendritic ulcers were subjected to genomic analysis to determine whether FHV-1 vaccine strains are involved in the formation of dendritic ulcers.
Methods: All open reading frame (ORF) sequences of the three F2 strains (Virbac, Intervet and Merial) and the FHV-1 clinical isolates from cats registered in GenBank were compared to detect nucleotide variants unique to the F2 strains, with those nucleotides then being used for simple genotyping of the F2 strains. In all isolates from feline eyes with dendritic ulcers, the regions including nucleotide variants of the F2 strain were amplified with PCR and sequenced.

Article Synopsis
- A 68-year-old male experienced irritation in both eyes, including symptoms like photophobia and tearing, after starting dupilumab for severe atopic dermatitis.
- He had a specific corneal ulcer in the right eye and a pannus in the left eye, but tests ruled out infections.
- Treatment with eye drops led to significant improvement, and follow-up revealed healing of the corneal lesions and improved vision.
