    Journal: Zhonghua Yan Ke Za Zhi; 2004 Sep; 40(9):597-600. PubMed ID: 15500763.
    Abstract:
    OBJECTIVE: To study the characteristics of optical coherence tomography (OCT) pictures in pathologic myopia. METHODS: 100 cases (195 eyes) of pathologic myopia were examined with OCT. The Age ranges of all the cases was 16-76 years and refraction error was -6.00 - -36.00 diopters. RESULTS: OCT image was normal in 7 eyes (4.3%), the reflectivity band of RPE and chorio-capillaries were uneven and thinning in 147 eyes (90.2%). Full-thickness macular hole was found in 21 eyes (10.8%), of which 10 (5.1%) eyes were associated with retinal detachment; local shallow retinal detachment was found in 24 eyes (12.3%), of which 7 eyes (3.6%) were associated with retinal schisis, 19 eyes (9.7%) with macular choroidal neovascularization (CNV). retinal swelling was often associated with the following diseases: Fuchs spot 9 eyes (4.6%), thick macular hemorrhage 3 eyes, epiretinal macular membrane 18 eyes (9.2%); macular sensory retina thinning in 5 eyes (2.6%). CONCLUSION: Compared with fundus examination including slit lamp with pan-retinoscope, OCT showed unique preference for observation of the changes of retinal pigment epithelium (RPE), chorio-capillary layer, diagnosis macular hole and epiretinal macular membrane, discovery of small sensory retinal detachment, schisis and thinning of sensory retina layer etc. OCT can not either discover a piece of thin macular hemorrhage or differentiation between thick macular hemorrhage and pigment spot.
