The aim of this study was to assess the safety of antifungal Amphotericin B as a supplement in corneal storage media(Optisol-GS®) for human corneal endothelial cells.
Five pairs of human corneas from 5 donors were divided into two groups. In the control group(C group), one corneal button of the pair was stored in Optisol-GS® for 7 days. In the treatment group(A group), its counterpart was preserved in in Optisol-GS® mixed with 40ug/10mL Amphotericin B 7 days after preservation. We compared endothelial cell counts before and after preservation in each group. We evaluated the mean changes of endothelial cell counts via specular microscopy between the 2 groups before and after 7 days of preservation. In addition, we assessed endothelial cell viability using Live/Dead assay kit (Calcein AM and ethidium homodimer) under scanning confocal microscopy(Carl Zeiss ®, LSM 800 with Airyscan).
Before preservation, the endothelial cell count was not different between two groups (p>0.05). The endothelial cell count before and after preservation did not statistically differ in each group(C group p=0.916, A group p=0.557). Before and after 7 days of preservation, the mean endothelial cell counts did not differ between two groups (before preservation ; p=0.690, after preservation; p=0.833). After 7 days of preservation, corneal endothelial death rate between 2 groups was not statistically significant in live/dead assay(p=0.0601).
Antifungal fortified Optisol-GS may significantly improve incidence of endopthalmitis of fungal origin after penetrating keratoplasty. This study found preservation in Optisol-GS mixed with Amphotericin B (4ug/mL) did not induce statistically significant toxicity on the endothelial cells in human cadaver corneas, when compared with the control group.
