In vivo rabbit eyecup preparation for use in retinal research.
OBJECTIVE
To develop an in vivo rabbit eyecup preparation that preserves neuronal and vascular connections with normal posterior segment contour, permitting direct access to the retina and facilitating retinal microsurgical and neuroscience research.


METHODS
Cyanoacrylate glue was applied to the anterior sclera of six Dutch-belted rabbits before open-sky vitrectomy. The glue was used to harden the compliant scleral wall and to fix it to the surrounding periorbital tissues.


RESULTS
A normal contour of the posterior segment was retained in all cases. Vitrectomy under air was successfully accomplished and an extensive removal of the vitreous gel was achieved. Fluorescein angiography revealed normal vascular patency of the retinal vessels after vitrectomy.


CONCLUSIONS
The proposed modification of the rabbit eyecup retains the normal neurovascular connections and configuration of the retina, making it suitable for retinal microsurgical maneuvers or any procedures in which easy access to anatomically undisturbed retina is required.
