Optical coherence tomographic images of preoperative and postoperative retinas. A-C: Shows a patient from the SB group. The patient was a 34 year old female, with Poor visual acuity (VA) and metamorphopsia for 15 days before operation. A. The best-corrected visual acuity (BCVA) among the preoperative retinas was 2.0. B. Typical residual retinal detachment can be seen 1 week after sclera bucking; the BCVA was 1.3. C, Typical residual retinal detachment can be seen 2 months after sclera bucking; the BCVA was 1.0. D-E: Shows a patient from the PPV group. The patient was a 42 years old female, with Poor visual acuity (VA) and metamorphopsia for 21 days before operation. D. Optical coherence tomographic images of a preoperative retina; the BCVA was 1.3. E. One month after primary vitrectomy operation, macular reattachment was successful in this patient, and no subretinal fluid was present; the BCVA was 0.3.
