Purpose: To clarify the fine structure of idiopathic macular hole using high OCT3 and the correlated factor with visual acuity. Methods:Thirteen eyes of twelve patients with idiopathic macular hole were examined using optical coherence tomography (OCT3). Ages were ranged form 37 to 78 years old (mean: 61). One eye had stage 2 hole, 8 had stage 3 and one had stage 4. Visual acuities were ranged from 0.03 to 0.7 (mean: 0.2). A cross sectional image through the fovea was obtained on the line of 5 mm. We analyzed the correlation between the visual acuity and tomographic feature of macular holes including diameter of macular hole, the diameter including fluid cuff and extent of cystoid edema. Results: The diameters of macular holes ranged from 40 to 680 um (mean: 350) and those with fluid cuff were from 700 to 1520 um (mean: 855). These diameters of macular holes had no correlation with visual acuity. OCT3 demonstrated small cysts in inner granular layer and large cysts in outer plexiform layer. The extent of large cysts around macular hole ranged from 1200 to 2120 um in diameter. It had negative correlation with visual acuity (R=-0.70, P<0.05). The extent of small cysts ranged from 1242 to 2800 um (mean: 2023), which had no correlation with their visual acuities. Conclusions: OCT3 revealed two types of cysts around macular hole, large one in outer plexiform layer and small one in inner granular layer. The extent of large cysts in outer plexiform layer had a negative correlation with their visual acuities.
