  • Look Inside

We reviewed clinical courses of 20 eyes of diabetic macular edema treated by vitrectomy. The follow-up periods ranged from 6 to 55 months, average 20.8 months. Eyes were judged as necessitating vitrectomy when no posterior vitreous detachment was present, the posterior hyaloid membrane appeared thick and when vitreous traction was highly suspected. At the final examination, the visual acuity improved by 2 lines or more in 12 eyes (60%), remained unchanged in 6 (30%) and deteriorated by 2 lines or more in 2 (10%) . The improvement in visual acuity was significant (p < 0.01) . The averaged visual acuity continued to improve till 2 years after surgery. Deterioration in visual acuity was due to accumulation of hard exudates in the macula in one eye and to retinal detachment and neovascular glaucoma in another. The findings show the efficacy of vitrectomy for diabetic macular edema over longer periods. Due precaution is necessary in deciding surgery because of possible severe complications after surgery.
