  • Optical coherence tomography of idiopathic macular epiretinal membranes

    Objective To study the characteristics of optic al coherence tomography (OCT) in idiopathic macular epiretinal membranes (IMEM) and the relationship between the thickness of fovea and the vision of affected eyes. Methods Total of 67 cases (73 eyes) with clinica l diagnosis of IMEM by direct, indirect ophthalmoscopy, three mirror contact len s, fundus color photography or fundus fluorescein angiography(FFA)were examined with OCT. Results Epiretinal membranes(ERMs) with macular edema were found in 32 eyes, proliferative ERMs in 20 eyes, ERMs with macular pseudoholes in 14 eyes and ERMs with laminar macular holes in 7 eyes. Based on OCT, the ERMs were clearly and partially seperated from the retina (27 eyes, 38.36%), the retinal thickness of the fovea was the thickest in proliferative ERMs and the thinnest in ERMs with laminar macular holes. The statistical an alysis showed there was a negative correlation between the thickness of fovea an d visual acuity (r=-0.454, P= 0.000 ). Conclusion There were four types of image of OCT in IMEM: ERMs with macularedema, proliferative ERMs, ERMs with macular pseudohole and ERMs with laminar macular hole;and the thicker the fovea under the OCT, the poorer th e visual acnity in the affected eyes with ERMs. (Chin J Ocul Fundus Dis, 2001,17:115-118)

  • The characteristics of congenital retinoschisis with optical coherence tomography

    Objective To investigate the characteristics of congenital retinoschisis of optical coherence tomography(OCT) and its clinical application. Methods Eight cases(15 eyes) which were diagnosed as or suspected to retinoschisis in clinic were examined by OCT,direct ophthalmoscopy and color fundus photograph.Three cases(6 eyes) were examined by electroretinogram(ERG) and fundus fluorescein angiography(FFA). Results The typical characteristic OCT images of congenital retinoschisis were cystic maculopathy with tilted and vertical connective filaments,typical split in innner retinal layers in posterior retina and thickening of neurosensory retina with the split of outer retinal layers in membranous remnants. Conclusions OCT can display the characteristics of congenital retinoschisis.It is potentially useful as a new technique for the diagnosis of congenital retinoschisis.
