【Abstract】 Objective To observe the characteristics of fundus fluorescein angiography (FFA) and optical coherence tomography (OCT) in juvenile retinoschisis. Methods The photochromes of the ocular fudus of 7 cases (14 eyes) who were diagnosed as juvenile retinoschisis were taken, among whom, 5 (10 eyes) were examined by FFA, and 6 (12 eyes) by OCT. Results In 8 eyes with cystiform stellate maculopathy under ophtalmoscope, the result of FFA showed granular fluorescence in different density and shape without exact connection of the configuration between these granules and the cystlike maculopathy. In 2 eyes with pigment disorder in the macula under ophthalmoscope, blocky fluorescence was found in FFA. In 3 eyes with peripheral schisis, FFA discovered distorted and dilated retinal capillaries with different extent, and flecks of non-perfusion area. OCT images revealed thickening of the macular neuroepithelium with laminal seperation, and cystic low-reflect areas in the inner layer. Conclusions In juvenile retinoschisis, pigment proliferation and degeneration in the macular area could be found. Granular fluorescence and cystic low-reflect areas could be seen in FFA and OCT, respectively.更多还原
