Imaging examinations reveal anatomical changes in patients treated by nonvitrectomizing vitreous surgery. A 68-year-old female patient. (1a) Fundus photography shows macular pucker with posterior vitreous detachment. (1b) Preoperative optical coherence tomography (OCT) reveals epiretinal membrane (ERM) with a central retinal thickness value of 624 μm and the tortured retina with DRIL at 4 points, grade 2. (1c) OCT at 3 months after surgery demonstrates a decrease of central retinal thickness to 393 μm and reorganized retinal layers (0 points, grade 0). The vision is improved from preoperative Snellen 0.15 to Snellen 0.3. A 60-year-old female patient. The paramacular ERM on fundus photography (2a) and rough retinal surface with DRIL at 4 points, grade 2 on OCT (2b) are presented. The rough surface becomes smooth postoperatively with distinct retinal layers and DRIL at 1 point, grade 1 (2c). The vision is improved from preoperative Snellen 0.15 to Snellen 0.4. A 68-year-old male patient. (3a) Fundus photography shows the opaque ERM and high reflection in the posterior pole. (3b) The preoperative tight adhesion, elevated foveal pit, and disorganized inner layers are demonstrated on the OCT image with DRIL at 1 point, grade 1. (3c) Postoperatively, the foveal pit is present, and retinal layers are well-defined with DRIL at 0 points, grade 0. The vision is improved from preoperative Snellen 0.4 to Snellen 1.0
