Abstract: : Purpose: OCT–Ophthalmoscope provides planer images of the fundus (C–scan), as well as the cross sectional images (B–scan). In eyes with idiopathic macular hole, OCT–Ophthalmoscope demonstrates cystoid changes surrounding a macular hole that shows petal like formations. We little know about the formation of the cystoid changes and the influence to visual function of the eyes with macular hole. We study B–scan and C–scan findings of cystoid changes of macular hole and the relation between the extension of the cystoid changes and visual acuity.Methods: We prospectively examined 25 eyes with idiopathic macular hole using OCT–Ophthalmoscope. The best corrected visual acuity was compared with the size of the petal like changes of the macular hole measured on the C–scan images. To compare the size of the changes, the size of the area was converted to disc area. Results: The cystoid changes in the outer retina appeared in eyes with stage 1 and 2 macular hole. In stage 3 and 4, OCT–Ophthalmoscope demostrated cystoid changes in both inner and outer retina. C–scan reveals that some of the inner cystoid spaces located outside the outer cystoid spaces. These inner cystoid spaces showed the double layer of cystoid spaces. The diameter of the cystoid changes became longest in the eyes with Stage 3 macular hole. Visual acuity shows the weak correlation to the total size of cystoid changes. Conclusions: The cystoid changes in the outer retina may cause the inner cystoid lesion, because the cystoid changes in the inner retina appear with the progression of the macular hole stage.
