[Vitreous surgery for subretinal neovascular membrane and hemorrhage].

OBJECTIVE

To study the indications, techniques and therapeutic effects of vitreous surgery for subretinal neovascular membranes.

METHODS

6 cases of subretinal neovascularization and subretinal hemorrhage were treated by vitreoretinal surgery. The surgical techniques consisted of three port pars plana vitrectomy, intraocular laser, retinotomy, subretinal neovascular membrane resection or hemorrhage removal, air-fluid exchange, etc. The pre and post-operative examinations included fundus fluorescein angiography (FFA), Humphry visual field to evaluate the therapeutic effects of the surgery.

RESULTS

The postoperative follow-up ranged from 4 to 7 months. The visual acuities of 4 cases improved, 0.3 or over in 2 cases and unchanged in 2 cases.

CONCLUSION

Subretinal operation may be a safe and effective method to treat subretinal neovascularization if the indication was well mastered.
