Abstract:
AIM:To evaluate the macular microstructural changes in patients with rhegmatogenous retinal detachment(RRD)after silicone oil tamponade by spectral-domain optical coherence tomography(SD-OCT).METHODS:From November 2019 to July 2021, 27 patients with 27 eyes in RRD who underwent vitrectomy combined with silicone oil tamponade in Cangzhou Aier Eye Hospital were enrolled in this study as the observation group, other 30 healthy volunteers with 30 eyes were included in the control group. The best corrected visual acuity(BCVA)of patients before and after operation were observed, and quantified evaluation of the postoperative macular microstructural changes were performed by SD-OCT.RESULTS: The BCVA(LogMAR)of the observation group at 1wk and 3mo after operation(0.61±0.23, 0.69±0.34)were improved compared with those before operation(1.43±0.77)(all P<0.01). The cube volume and average cube thickness in the macular area at 3mo after operation in the observation group were lower than those at 1wk and 1mo after operation in the control group(all P<0.05). There were no differences in the average ganglion cell-inner plexiform layer(GCIPL)thickness, minimum GCIPL thickness, average macular retinal nerve fiber layer(mRNFL)thickness and minimum mRNFL thickness at 1wk, 1 and 3mo after operation in the observation group, but all decreased compared with the control group(all P<0.01). There were 9 eyes with subretinal fluid(SRF)in the observation group during postoperative follow-up, SRF had a tendency to be gradually absorbed, but 1 eye had a secondary macular hole; 3 eyes had ellipsoid zone disruption, which had a tendency to be gradually repaired; 2 eyes had submacular perfluorocarbon liquid; 2 eyes had macular edema.CONCLUSION: SD-OCT can show the microstructure and morphological changes very well in macular area in patients with RRD after silicone oil tamponade, and has important clinical value for the preoperative and postoperative follow-up evaluation of RRD.
