title: Recovery of photoreceptor inner and outer segment layer thickness after reattachment of rhegmatogenous retinal detachment.
abstract: OBJECTIVE
  To evaluate the recovery of retinal function and the thicknesses of the photoreceptor inner (IS) and outer segment (OS) layers after a reattachment of a rhegmatogenous retinal detachment (RRD).
  
  
  METHODS
  49 eyes of 49 patients (mean age, 57.4±10.3 years) with successfully reattached RRD were retrospectively studied. Spectral-domain optical coherence tomography was used to obtain images of the foveal area, and the thicknesses of the IS and OS were measured before and 1, 3, 6 and 12 months after surgery. The thicknesses of the corresponding structures of the healthy fellow eye served as control.
  
  
  RESULTS
  The thickness of the IS layer was 20.4±5.0 μm and that of the OS layer was 34.4±9.7 at 1 month after surgery, which was significantly thinner than the IS (28.9±2.9) and OS (55.4±5.2) layers of the fellow eyes. The thicknesses gradually increased and were not significantly different from that in the fellow eye at 12 months (IS, 28.4±4.4 µm and OS, 50.7±6.6 µm). The IS and OS thicknesses at 1 month after surgery in eyes that had a decimal visual acuity of 1.0 at 6 months were significantly thicker than those in eyes that had a visual acuity of <1.0.
  
  
  CONCLUSIONS
  The increase in the thicknesses of the IS and OS layers of the photoreceptors during the recovery phase of eyes with RRD indicates that the recovery process was slow and gradual. Quantitative analysis of the IS and OS thicknesses may be useful to follow the disease process.
