Imaging examinations reveal anatomical changes in patients treated by pars plana vitrectomy. A 65-year-old female patient. (4a) Fundus photography shows ERM with twisted vessels. (4b) Preoperative OCT reveals the elevated and disorganized retina and intra-layer schisis with DRIL at 4 points, grade 2. (4c) OCT at 3 months after surgery demonstrates the retinal structure was reformed with DRIL at 2 points, grade 1. The vision is improved from preoperative Snellen 0.3 to Snellen 0.4. A 70-year-old female patient. (5a) Fundus photography shows ERM presenting as a translucent membrane on the macular surface. (5b) Preoperative OCT reveals the nerve fiber layer is stretched and the inner layers are disorganized with DRIL at 3 points, grade 2. (5c) OCT at 3 months after surgery demonstrates the traction is relieved and the retinal layers are distinct with DRIL at 0 points, grade 0. The vision is improved from preoperative Snellen 0.4 to Snellen 0.8. A 72-year-old male patient. (6a) Fundus photography shows ERM presenting as a white strip with DRIL at 4 points, grade 2 (6b). (6c) OCT at 3 months after surgery demonstrates DRIL at 0 points, grade 0. The vision is improved form preoperative Snellen 0.5 to Snellen 1.0.
