Objective To investigate the protective effect of nerve growth factor (NGF) on apoptosis of cultured human fetal retinal pigment epithelium (HFRPE) cells induced by indomethacin (IN) in vitro.Methods Subcultured HFRPE cells were treated with different concentrations of IN to establish apoptotic model. The protective effect of NGF on apoptosis of cultured HFRPE cells were assessed using an acridine orange (AO) staining method and transmission electron microscopy (TEM).Results HFRPE cells exposed by 200-600 μmol/L IN for 24 hours elicited typical apoptosis morphological changes, including condensed chromation, nuclear fragmentation and reduction of nuclear size and cell volume. There was a statistically difference in HFRPE cells with apoptosis between 200 μmol/L IN+500 μg/L NGF and 200 μmol/LIN groups ( q=3.9204，P=0.0320); there was a significant difference in HFRPE cells with apoptosis in 400 μmol/L IN+500 μg/L NGF and 400 μmol/ L IN as well (q=9.7915，P=0.0001). Conclusion NGF has an protective effect on IN-induced HFRPE cells apoptosis. (Chin J Ocul Fundus Dis，2003，19：38-41)
