Vitrectomy for chronic peudophakic cytoid macular edema Original Reearch Article

PURPOE: We report the reult of par plana vitrectomy for chronic peudophakic cytoid macular edema unreponive to medical treatment. METHOD: Retropective analyi of 23 conecutive eye of 23 patient with chronic peudophakic cytoid macular edema wa performed. Eye with vitreou incarceration into the cataract wound or vitreou–cornea contact were excluded from the tudy. Preoperatively, all eye had cytoid macular edema confirmed on fluorecein angiography and were unreponive to medical treatment. Par plana vitrectomy wa performed uing tandard technique and vitreou adheion to the iri, intraocular len, or both were lyed if preent. REULT: The mean interval between cataract urgery and vitrectomy wa 32.3 ± 30.9 month (median, 20 month; range, 3 to 110 month). The vitreou wa adherent to the iri or intraocular len in 12 eye (52.2%) and wa preent in the anterior chamber with no evidence of adheion in even eye (30.4%). In four eye (17.4%) the vitreou wa poterior to the iri plane with no adheion to anterior egment tructure. The median preoperative bet-corrected viual acuity wa 20/200, and the median final potoperative bet-corrected viual acuity wa 20/60 (P < .0001) after a mean follow-up of 30.2 ± 31.2 month (median, 14 month; range, 2 to 109 month). Final bet-corrected viual acuity improved by a mean of 3.3 ± 2.6 nellen line, with a median percent change of 70% (mean, 57.3%; range, 0% to 99%). In all 23 eye the cytoid macular edema reolved potoperatively by biomicrocopic examination in a mean period of 3.3 month (median, 2 month; range, 1 to 12 month). CONCLUION: In peudophakic eye with chronic cytoid macular edema unreponive to medical treatment, vitrectomy reulted in reolution of the cytoid macular edema with improved viual acuity in ome cae. Clinical improvement may occur in eye with no apparent vitreou diturbance.
