This manuscript describes a method for submacular transplantation of retinal pigment epithelial cells in the NHP eye and strategies to prevent intraoperative complications associated with macular manipulation. Immunology and Infection Bead Based Multiplex Assay for Analysis of Tear Cytokine Profiles Praveen Kumar Balne1,2, Veonice Bijin AU3, Louis Tong2, Arkasubhra Ghosh4, Mukesh Agrawal5, John Connolly3, Rupesh Agrawal1 1National Healthcare Group Eye Institute, Tan Tock Seng Hospital, 2Singapore Eye Research Institute (SERI), 3Institute of Molecular and Cell Biology, A*STAR, 4GROW Research Laboratory, Narayana Nethralaya Foundation, 5Vimta Labs Limited Analysis of tear film cytokines helps in studying various ocular diseases. Bead based multiplex assays are simple and sensitive and enable the testing of multiple targets in samples with small volumes. Here we describe a protocol for tear film cytokine profiling a using bead based multiplex assay. Immunology and Infection A Non-invasive Way to Isolate and Phenotype Cells from the Conjunctiva Tanima Bose1, Aihua Hou2, Ryan Lee2, Louis Tong2,3,4,5, K. George Chandy1 1Lee Kong Chian School of Medicine, Nanyang Technological University, 2Singapore Eye Research Institute, 3Singapore National Eye Center, 4Duke-NUS Medical School, 5Yong Loo Lin School of Medicine The exposed normal ocular surface consists of cornea and conjunctiva. Epithelial cells, goblet cells and immune cells are present in the conjunctiva. Here, a non-invasive, technique of impression cytology is described using an impression cytology device and flow cytometry to analyze immune cells in the conjunctiva. Immunology and Infection A Chronic Autoimmune Dry Eye Rat Model with Increase in Effector Memory T Cells in Eyeball Tissue Aihua Hou1,2, Tanima Bose3, K. George Chandy3, Louis Tong1,2,4,5 1Singapore Eye Research Insitute, A Member of SingHealth, 2DUKE-National University of Singapore Medical School, 3Lee Kong Chian School of Medicine, Nanyang Technological University, 4Singapore National Eye Center, 5Yong Loo Lin School of Medicine, National University of Singapore This report describes a method to induce chronic experimental autoimmune dry eye in Lewis rats through immunization with an emulsion of rat lacrimal gland extract, ovalbumin, and complete Freund's adjuvant, followed by the injection of lacrimal gland extract and ovalbumin into the forniceal subconjunctiva and lacrimal glands six weeks later.
