Objective To evaluate different methods in determ ining the postoperative changes of anatomical structures in macular diseases． Methods Thirty-one eyes of 31 cases of macular diseases, were studied among them there were 15 eyes with idiopathic macular hole (IMH),and the others included 8 eyes with macular epiretinal membranes(ERMs), 4 eyes with age relate d macular degeneration(AMD) and 4 eyes with idiopathic submacular neovasculariza tions(SRNV)． All cases were examined with retinoscope or retinogra phy, fundus fluorescein angiography (FFA) and optical coherence tomography (OCT ) pre-and postoperatively． Results Funduscopy showed that all of the 15 IMHs were closed after operation, but OCT showed th at among them 2 affected eyes still had partial retinal detachment at the macular hole edge in one quadrant and the sensory layer in macular area became thinner in 1 affected eye． FFA revealed damage of retinal pigment epithelium (RPE) in 5 cases． As for the ERMs and SRNV, funduscopy could n ot identify wether they were completely removed or not after operation． FFA ind icated that SRNV and SRNV were completely removed and the damage of RPE．OCT discovere d that the ERMs and SRNV were completely removed and the sensory layer became th inner in 3 eyes． Conclusion The combination of funduscopy , FFA and OCT can get the whole view of macular diseases and their postopera tive anatomical evaluation． (Chin J Ocul Fundus Dis, 2001,17:33-36)
