Long-term visual outcomes of vitrectomy for cystoid macular edema due to nonischemic central retinal vein occlusion.

Purpose: To report the long-term surgical outcome of vitrectomy for cystoid macular edema due to nonischemic central retinal vein occlusion (CRVO).

Methods: A retrospective chart review of 25 consecutive eyes (25 patients) with cystoid macular edema due to nonischemic CRVO treated with vitrectomy was performed. All patients underwent a pars plana vitrectomy with the creation of a posterior vitreous detachment if still attached.

[The influence of hard exudates on the results of vitrectomy for macular edema due to diabetic retinopathy].

Purpose: To demonstrate surgical results of diabetic macular edema from the distribution of hard exudates.

Methods: We reviewed 485 eyes of 325 patients followed up more than 1 year who underwent vitreous surgery for diabetic macular edema. Four groups were identified from the distribution of hard exudates in the macular region: no hard exudate type, 179 eyes; hard exudate type, 211 eyes; macular deposit type, 73 eyes; and waxy type, 22 eyes.

[Subretinal washout for subtle subfoveal hard exudates in diabetic macular edema].

Purpose: To evaluate the efficacy of subretinal washout for subtle subfoveal hard exudates in diabetic macular edema.

Methods: This study was done retrospectively on a series of patients with diffuse diabetic macular edema accompanied with subtle subfoveal hard exudates and operated on by one surgeon(NO). Patients ranged in age from 30 to 76 years(mean, 59 years).
