Here, we describe a platform that allows noninvasive in vivo imaging of liver spheroids engrafted in the anterior chamber of the mouse eye. The workflow spans from generating spheroids from primary liver cells to transplantation into the mouse eye and in vivo imaging at cellular resolution by confocal microscopy.

The goal of the protocol is to show longitudinal intravital real-time tracking of thymocytes by laser scanning microscopy in thymic implants in the anterior chamber of the mouse eye. The transparency of the cornea and vascularization of the graft allows for continuously recording progenitor cell recruitment and mature T-cell egress.

The overall goal of this protocol is to measure greenhouse gas emissions from paddy fields using the static closed chamber technique. The measurement system needs specific adjustments due to the presence of both a permanent water layer in the field and of the plants within the chamber headspace.
FAQs
Continuous delivery of balanced irrigation solution compensates for fluid lost when surgical instruments enter or leave the eye. This helps preserve anterior chamber depth and supports intraocular pressure during manipulation. By limiting sudden changes in the fluid-filled space, the device provides a more stable environment for microsurgical work and reduces the likelihood of chamber collapse.
A controlled flow supplies fluid at a regulated rate rather than allowing the chamber to lose volume unpredictably. The resulting balance helps maintain visualization and chamber stability while instruments move through the operative field. This is especially relevant when repeated instrument exchanges could otherwise contribute to fluid loss, changing pressure, or reduced working space.
The cannula is introduced through a small corneal or limbal incision, placing its fluid-delivery pathway directly into the anterior chamber. This position allows irrigation to continue while other instruments enter through the surgical access site. Proper placement therefore supports chamber maintenance without eliminating the access needed for precise ophthalmic manipulation.
Maintaining chamber depth helps reduce collapse during procedures in which fluid may escape or instruments repeatedly enter and leave the eye. A stable chamber also helps protect intraocular structures from the consequences of a changing operative space. These effects support safer, more precise manipulation and can improve the surgeon’s view of the surgical field.
Use begins by positioning the cannula through a small corneal or limbal incision and connecting its irrigation pathway to a controlled supply of balanced solution. During surgery, the device continuously replaces fluid lost from the chamber. Its ongoing infusion maintains depth and supports intraocular pressure while the surgeon performs microsurgical maneuvers.
The device can support cataract extraction, glaucoma surgery, and corneal transplantation by preserving a stable anterior chamber during operative manipulation. These procedures differ in their surgical goals, but each may require instruments to enter the eye and may involve fluid loss. Continuous irrigation helps maintain visualization and working conditions across these applications.
Its main contribution is a controlled operative environment with improved visualization, preserved chamber depth, and support for intraocular pressure. These conditions help surgeons manipulate tissues and instruments more precisely while reducing chamber collapse. In medicine, the device is therefore relevant not only as an irrigation component but also as a means of supporting safer anterior-segment surgery.
