Analyses Of Correlative Factors Of Development Of Choroidal Neovascularization In Pathologic Myopia And Investigation On Its Image Of Optical Coherence Tomography

ObjectiveTo investigate on the image futures of OCT of CNV in pathologic myopia, and to analyze that if the ocular axial length and dilopter had any correlation of development of CNV.MethodsThirty - four patients (sixty eyes) were diagnosed as myopia from November 2004 to June 2006 at FUSHUN OPHTHALMIC HOSPITAL . All patients were examined under A scan,B scan, diopter ,FFA and OCT. CNV was detected by OCT and FFA . Record the pathologic change on the macula. The condition of 50 eyes with ocular axial length≥26 mm diopter ≥6.00D(test group) was compared with other 10 eyes with axial <26 mm diopter <6. 00D( control group). The results were analyzed by correlative test and x~2 test.ResultThere were thirty - nine eyes in test group were detected CNV, and only 1 eye in control group. There were statistically significant differences between two groups in AL,D and development of CNV (P < 0. 05). In test group 36 eyes were detected CNV by FFA, 39 eyes were detected CNV by OCT. There were statistically significant to compare the detection rate on CNV between OCT and FFA (x~2<0.01).
