RESUMEN
The ocular manifestations of leukemia include leukemic infiltration in optic nerve, retina, choroid, iris, ciliary body and anterior chamber, as well as retinal vascular change and hemorrhage due to systemic hemodynamic abnormalities.Occasionaly, subhyaloid hemorrhage involving the macula may cause acute loss of central visual acuity. We observed dense bilateral macular subhyaloid hemorrhage in 19-year-old man who had been diagnosed to have acute myeloid leukemia.Trans pars plana vitrectomy was performed in his both eyes, resulting in improvement of vision.

Medical record of 66 eyes which had undergone pars plana vitrectomy for the treatment of proliferative diabetic retinopathy were reviewed to study their clinical features, incidences and types of complications, visual outcome, and visual prognostic factors. The final visual outcome showed the improvement in 50[76%] eyes, no change in 13[20%]eyes, and the worsening in 3[4%] eyes. Preoperative prognostic factors favoring final visual acuity included the followings:1]insulin dependent diabetes mellitus which developed before 30 years of age, 2]absence of iris neovascularization, 3]absence of tractional macular detachment. Postoperative complications included vitreous hemorrhage in 34[52%]eyes, cataract in 12[19%]eyes, increased intraocular pressure in 6[10%]eyes, rhegmatogenous retinal detachment in 4[6%]eyes, choroidal effusion in 3[5%]eyes, corneal epithelial defect in 2[3%]eyes, neovascular glaucoma in 1[2%] eye. Postoperative complications associated with poor visual outcome were rhegmatogenous retinal detachment and neovascular glaucoma.Intraoperative complication of iatrogenic retinal tear did not seem to deteriorate the final visual acuity.
