  • Investigation of the association between the macular volume and thick ness by optical coherence tomography, with refraction state and axial length in children

    Purpose To investigate the association between the macular volume and thickness, as assessed by optical coherence tomography (OCT), with refraction state and axial length (AL) in children. Methods A total of 100 normal children whose right eyes were randomly selected were divided into five groups due to their refraction, comprising hyperopia, emmetropia, low myopia, moderate myopia, high myopia. The AL of the eyes was measured by IOL mas ter measuring machine. Then the macular volume and thickness were measured by OCT. Results Children with high myopia have smaller macular volume and thinner parafoveal retinal thickness (especially out-ring macular). The minimum thickness and average thickness of the fovea were not significantly different among the five groups. The macular volume ,total average macular thickness and quadrant-specific macular thickness(except the nasal inner quadrants) were positively associated with refraction and negatively associated with AL, while t here were no correlation between minimum foveal thickness, the average foveal th ickness and refraction or AL. Conclusions In Chinese children, increasing axial length was associated with reduced macular volume and thickness (except the foveal region and the nasal inner quadrant). (Chin J Ocul Fundus Dis,2008,24:114-117)

  • Optical coherence tomography features of central exudative chorioretinopathy

    Objective lt;brgt;To investigate the morphological features of choroidal neovascularization (CNV) in central exudative chorioretinopathy (CEC) using optical coherence tomography(OCT). lt;brgt; lt;brgt;Methods lt;brgt;OCT and fundus fluorescein angiography (FFA) were performed in 41 cases (43 eyes) of CEC,and the course of CEC disease was from 1 week to 10 months. Twenty-seven of 43 eyes were also examined by indocyanine green angiography (ICGA). lt;brgt; lt;brgt;Results lt;brgt;OCT images revealed 5 kinds of morphological features of CEC: well-defined CNV(41.86 %),poorly-defined CNV(30.23 %),hemorrhagic pigment epithelium detachment (PED)(16.28 %), CNV companied with serous (6.98 %) or hemorrhagic neurosensory retina detachment (4.65 %). CNV mainly showed well-defined and poorly-defined CNV (72.09 %).In those eyes that could clear define the CNV boundary,there were 12 eyes on FFA examination and 20 eyes on ICGA examination which defined the boundary from retinal horizontal plane, while there were 23 eyes on OCT examination which defined the boundary from retinal vertical section. Classic CNV on FFA consistently presented with well-defined boundaries on OCT, whereas non-classic CNV had a variable cross-sectional appearance. lt;brgt; lt;brgt;Conclusions lt;brgt;The OCT morphological features of CNV in CEC is mainly well-defined CNV and poorly-defined CNV; OCT examination can precisely observe the retinal and choriocapillaries pathological anatomy of CEC from retinal vertical section, in making the CEC diagnosis as an important complementary examination of FFA and ICGA which observe the focus from retinal horizontal plane. lt;brgt; lt;brgt;(Chin J Ocul Fundus Dis, 2002, 18: 121-124)
