The subretinal implantation of retinal pigmented epithelium (RPE) is one of the most promising approaches for the treatment of degenerative retinal diseases. However, the performance of preclinical studies on large-eye animal models remains challenging. This report presents guidelines for the subretinal transplantation of RPE on a cell carrier into minipigs.

Many vision-threatening ocular diseases are associated with dysfunctional retinal microvessels. Therefore, the measurement of retinal arteriole responses is important to investigate the underlying pathophysiological mechanisms. This article describes a detailed protocol for mouse retinal arteriole isolation and preparation to assess the effects of vasoactive substances on vascular diameter.
FAQs
Balanced salt solution helps maintain intraocular pressure while the vitrector cuts and aspirates vitreous. This fluidic support works alongside the surgical ports and illumination system, allowing the surgeon to remove material without losing control of the intraocular environment. For bioengineers, the pressure-maintenance requirement motivates precise fluidics and instrument integration within compact ophthalmic systems.
Each instrument addresses a different task. The vitrector removes vitreous through simultaneous cutting and aspiration, illumination provides visualization inside the eye, and forceps enable tissue manipulation. Their coordinated use gives the surgeon access, visibility, and mechanical control during microsurgery. This combination also illustrates why bioengineering must address cutting, fluid flow, optical access, and tissue handling together.
Ports placed through the pars plana provide access for the vitrector, fluid delivery, illumination, and tissue-manipulation tools. Their small scale reflects the microsurgical nature of the procedure and creates engineering demands for miniaturized instruments that can operate within a confined ocular space. Port-based access therefore links surgical technique with device size, positioning, and procedural precision.
The procedure uses small pars plana ports to introduce the surgical instruments, establishes visualization with illumination, and removes vitreous through cutting and aspiration. Balanced salt solution maintains intraocular pressure during this process, while forceps can manipulate tissues when needed. This workflow combines access, visualization, fluid control, and tissue removal rather than treating them as separate operations.
Pars Plana Vitrectomy supports treatment of retinal detachment, vitreous hemorrhage, epiretinal membranes, and complications of diabetic eye disease. These conditions differ in their effects on the retina or vitreous, but they share a need for controlled access to the posterior segment. The procedure's value comes from combining removal of obstructive material with direct tissue visualization and manipulation.
The procedure provides a practical framework for developing smaller surgical instruments, improved intraocular visualization, controlled fluidics, and biomaterials intended to support postoperative healing. These engineering areas address different stages of care, from precise intraoperative manipulation to recovery after tissue intervention. Studying the procedure therefore connects device design with microsurgical safety, visual access, pressure control, and healing-related goals.
