The Image Futures of Optical Coherence Tomography of the Pathological Changes in Degenerative Myopia

SHI Le LI Lei JIANG Chunhui,et al.Department of Ophthalmology,EENT Hospital,Fudan University,Shanghai 200031  
Objective:To observe the pathological changes of degenerative myopia by optical coherence tomography (OCT). Methods: The OCT data of 100 patients (172 eyes)with degenerative myopia were retrospectively analyzed . The scan models of OCT included macular thickness map,fast macular thickness and line. Scans were undertaken at the regions of macular, optic papilla,posterior pole of retina , temporal larger retinal vessels,temporal crescent and pigment distribution abnormality. Results: Four categories were divided according to different parts where pathologic changes developed. At vitreoretinal interface, we found posterior vitreous hyaloid inserting to the retinal surface in 89 eyes (51.7%) ,full-thickness macular hole in 15 eyes (8. 7%), lamellar macular hole in 2 eyes(1.2%),epiretinal memberane (ERM) in 11 eyes(6. 4%). In retina layer,posterior shallow retinal detachment were found in 13 eyes (7. 6%),of which 5 eyes(2. 9%) associated with outer retinal schisis and 2 eyes(1.2%) associated with inner retinal schisis. In RPE and choroidal layer , we found RPE atrophy in 140 eyes(81.4%), Fuchs spots in 10 eyes(5.7%), temporal crescent in 165 eyes (95.9%) ,choroidal atrophy in 117 eyes(68. 0%)and macular choroidal neovascularization in 25 eyes(14. 5%). In sclera layer, posterior staphylomas were observed in 146 eyes (84. 9%). Conclusion :OCT can display the pathological changes of retinal tissues of degenerative myopia in vivo.
