Long-term results of lens-sparing vitrectomy for stages 4B and 5 retinopathy of prematurity Choi J; Kim JH; Kim SJ; Yu YSKorean J Ophthalmol 2011[Oct]; 25 (5): 305-10PURPOSE: To assess long-term anatomic and visual outcomes and associated complications of lens-sparing vitrectomy (LSV) for treatment of tractional retinal detachments (TRDs) associated with stages 4B and 5 retinopathy of prematurity (ROP). METHODS: We performed a retrospective review of medical records and data analyses of consecutive patients who presented with stages 4B and 5 ROP and underwent LSV from 1999 to 2007. Retinal reattachment status, visual acuity and postoperative complications were evaluated. RESULTS: Twenty-one eyes of 20 patients, including 13 eyes with stage 4B ROP and 8 eyes with stage 5 ROP, were examined. The mean follow-up period was 5.6 years. In 9 (43%) out of 21 eyes, retinas were eventually reattached. The anatomic success rates were 62% in stage 4B and 13% in stage 5 ROP. In eyes with reattached retinas, visual acuity better than form vision was shown in 7 eyes (78%), whereas no light perception was present in 10 eyes (83%) among eyes with TRD on final examination. Postoperative intraocular hemorrhage occurred in nine eyes (43%). Long-term complications of cataract, corneal opacity, glaucoma and strabismus developed in 4 (19%), 6 (29%), 7 (33%) and 8 (38%) eyes, respectively, and were more common in eyes with TRD. CONCLUSIONS: After following-up for a mean of 5.6 years, the anatomical success rate of LSV was encouraging for the correction of TRD associated with stage 4B ROP but not for stage 5 ROP. Retinal reattachment is important for obtaining better visual outcomes and preventing the development of late complications.|*Infant, Very Low Birth Weight[MESH]|Female[MESH]|Follow-Up Studies[MESH]|Humans[MESH]|Infant, Newborn[MESH]|Lens, Crystalline/*surgery[MESH]|Male[MESH]|Retinopathy of Prematurity/diagnosis/physiopathology/*surgery[MESH]|Retrospective Studies[MESH]|Severity of Illness Index[MESH]|Time Factors[MESH]|Treatment Outcome[MESH]|Visual Acuity[MESH]|Vitrectomy/*methods[MESH] |
