Nonvitrectomizing vitreous surgery: A strategy to prevent postoperative nuclear sclerosis☆
Section snippets
Materials and methods
From December 1995 through June 1997, 21 patients with idiopathic EMP underwent unilateral nonvitrectomizing vitreous surgery at our institution. Eyes chosen for surgery had epiretinal membranes within the temporal arcades and symptoms of visual loss or metamorphopsia. Patients who had undergone previous intraocular surgery or had a history of other ocular disorders in the EMP eye and patients with asymmetric lens opacities in the two eyes were excluded from the study. Eyes that had more than a
Results
We performed nonvitrectomizing vitreous surgery in 21 eyes of 21 patients with EMP. There were 5 men and 16 women, ranging in age from 51 to 77 years (mean, 62.0 years). We randomly assigned 11 eyes to group 1 (membrane left floating in the vitreous cavity), and 10 eyes to group 2 (membrane removed from the eye). The follow-up period ranged from 6 to 24 months (mean, 9.7 months). Nineteen of the 21 eyes had final visual acuity equal to or better than preoperative levels (Fig 1).
There were no
Discussion
Nonvitrectomizing vitreous surgery under ordinary set-up was first described by Charles15 in 1987. He described membrane peeling and excision without removal of the vitreous in patients with EMP and small membranes but recommended core vitrectomy when membranes were larger and denser. Charles later abandoned nonvitrectomizing surgery because of initial postoperative floaters and vitreous opacities (personal communication, 1997).
Some hypotheses have been proposed regarding the possible causes of
