  • Look Inside

We evaluated the pseudohole of the macula in 19 eyes using an optical coherence tomography (OCT). Par-ticular attention was paid to the relation between the foveal configuration and visual disturbances including metamor-phopsia and visual acuity. We could identify four types of pseudohole based on horizontal and vertical sections. Nine eyes (type 1) showed a cylinder shape in both sections. Four eyes (type 2) showed a cylinder shape in one section and an inward shelf at the superior margin. Three eyes (type 3) showed a triangular shape in one side and an inward shelf in another. Three eyes (type 4) showed a triangular shape in both sections. Metamorphopsia was present in one eye (11%) in type 1, in none in type 2, in 2 eyes in type 3 (67%), and in 3 eyes (100%) in type 4. There was no difference in visual acuity among the four types. Vitrectomy was performed in 7 eyes with metamorphopsia and/or im-paired visual acuity. After surgery, metamorphopsia decreased in 3 of 4 eyes (75%). Visual acuity improved by 2 lines or more in 3 of 7 eyes (43%).
