Cholestasis is a clinical condition commonly encountered by both surgeons and gastroenterologists. Creation of a reversible cholestatic rat model can be challenging in view of the smaller size and unique hepatopancreatobiliary anatomy in rats. This video article demonstrates the creation of a reversible cholestatic model.

Source: Jose Roberto Moreto and Xiaofeng Liu, Department of Aerospace Engineering, San Diego State University, San Diego, CA Wind tunnel tests are useful in the design of vehicles and structures that are subjected to airflow during their use. Wind tunnel data are generated by applying a controlled air flow to a model of the object being studied. The test model usually has a similar geometry but is a smaller scale compared to the full-sized object. To ensure accurate and useful data is collected...

We demonstrate the effect of scleral crosslinking with riboflavin and UVA on an axial elongation rabbit eye. Axial elongation was induced in 13 day-old New Zealand rabbits (male and female) by suturing their right eye eyelids (tarsorrhaphy).
FAQs
The overlying scleral tissue can function as a valve after the eye is entered. This arrangement helps limit direct communication through the incision and can reduce wound leakage. By supporting a more secure entry, the tunnel may allow the surgeon to use no sutures or only minimal suturing, depending on the surgical requirements.
Beginning with a partial-thickness incision preserves tissue over the entry pathway before the surgeon reaches the eye. That layered construction helps protect the access site and reduces disruption to the cornea compared with placing the primary entry directly through corneal tissue. The design therefore supports wound stability while maintaining access to intraocular structures.
A protected scleral entry can support healing by reducing the extent of corneal disruption during surgery. Preserving corneal tissue and shape is clinically relevant because the approach is intended to maintain the eye’s structure after the procedure. These features may contribute to more stable postoperative wound behavior and improved outcomes in appropriate ophthalmic operations.
The surgeon first forms an incision that does not pass through the full scleral thickness. This incision is then extended within the sclera to create a tunnel, after which the pathway is opened into the anterior chamber or another intended intraocular location. The sequence creates a protected route before direct entry into the eye.
Scleral tunnel creation may be incorporated into cataract extraction, intraocular lens implantation, and glaucoma surgery. In each setting, the tunnel provides an access route while addressing the need for a secure ocular entry. Its value is greatest when the operation requires access to the anterior chamber or other intraocular structures with limited corneal disruption.
The technique is designed to promote a secure, self-sealing or minimally sutured wound. Its potential benefits include reduced leakage, support for postoperative healing, preservation of corneal shape, and improved postoperative outcomes. These effects arise from the protected tissue pathway and are relevant when surgeons need reliable intraocular access without unnecessarily disrupting the cornea.
