Mucin secretive conjunctival goblet cells (CGCs) in the eye are important for tear film stability and ocular surface health. Because CGC dysfunction is associated with various ocular surface diseases, non-invasive CGC examination will be of great help in the diagnosis and treatment. In this study, we developed a high-speed moxifloxacin-based extended depth-of-field microscopy for real-time CGC examination. The performance was demonstrated by high-speed CGC imaging of both mouse and rabbit models, in vivo. The imaging was insensitive to breathing motion, and the image resolution was sufficient to resolve individual CGCs in rabbit models.
Surgical resection is the primary treatment for malignant brain tumors. This procedure has a dilemma—aggressive surgical resection tends to extend patient survival; however, it also increases the risk of neurological deficiencies. Current medical imaging methods are not sensitive and their interpretation largely depend on surgeon’s impression. High-speed cellular imaging method by using clinically applicable moxifloxacin was demonstrated for fast and sensitive tumor-detection. The detailed cytoarchitecture of brain tumor mouse model and malignant human brain tumors was revealed. This study showed the potential and feasibility of moxifloxacin-based confocal microscopy as a surgery-guiding method for tumor removal.
