Purpose: To demonstrate that fluorophore assisted retinal break detection is possible using an in vivo model of rhegmatogenous retinal detachment(RRD) Methods: Intubated hybrid pigs underwent 3-port pars plana vitectomy with creation of a RRD by subretinal injection of dilute viscoelastic. Cy3 anti-GFAP was injected into the vitreous cavity at the time of initial surgery, or as follow-up operations, and then rinsed from the eye. Excitation illumination was provided by a 532nm diode pumped laser transmitted to the eye via a standard endoscopic fibre-optic cable. Barrier filters were fitted to the operating microscope. Results: Consistent with our previous ex vivo studies, Cy3 anti-GFAP selectively labelled exposed glial cells at the margin of retinal breaks. Retinal breaks that were not evident using standard white-light endo-illumination were clearly visible when viewed through barrier filters, and illuminated with laser-light. There was negligible background staining, and confocal imaging of excised retinal breaks indicated a signal-to-noise ratio in excess of 250. Conclusion: This study confirms that Cy3 anti-GFAP can be used peroperatively to enhance the detection of retinal breaks.
