Abstrakt: Clinical Relevance: Primary retinectomy in eyes not previously vitrectomized has been previously rarely performed in a minority of cases, unlike non-primary retinectomies in vitrectomized eyes.
Background: This paper aims to determine anatomical and functional outcomes of primary retinectomy, and to assess structural macular changes among successful cases.
Methods: In this retrospective multicentre cohort-study, 35 primary retinectomies in eyes undergoing initial vitrectomy for rhegmatogenous retinal detachment complicated by proliferative vitreoretinopathy C or D between 2014 and 2021 were included. The mean follow-up duration was 48 ± 59.24 months among successes and 46.54 ± 20.99 months among unsuccesses (p = 0.483).
Results: The anatomical success rate was 48.5% after one retinectomy and 60% after two retinectomies. Mean postoperative best corrected visual acuity (BCVA) was 1.85 ± 0.62 logMAR (6/425 Snellen equivalent). The difference from mean preoperative BCVA was not significant (p = 0.312). Final BCVA ≥ 6/60 was achieved in 17% of cases, and no cases gained ≥6/24. Final mean postoperative BCVA of successes was 1.69 ± 0.60 logMAR (6/294 Snellen equivalent) compared with 2.10 ± 0.57 logMAR (6/756 Snellen equivalent) of unsuccessful cases (p = 0.101). Post-operative macular optical coherence tomography was obtained from 95% of successes. Normal macular profile was found in 10% of cases, and the other cases demonstrated exudative maculopathy (60%), tractional maculopathy (20%) and macular atrophy (10%). Final BCVA was significantly higher in eyes with normal macular status compared to eyes with exudative maculopathy (p = 0.045) and macular atrophy (p = 0.025).
Conclusion: Primary retinectomy may be used for rhegmatogenous retinal detachment complicated with advanced proliferative vitreoretinopathy. Anatomical and functional outcome were inferior than non-primary retinectomies for grade C proliferative vitreoretinopathy. Functional outcome was influenced by macular status. Positive prognostic factors include final anatomical success and normal final macular anatomy.
