T. Ikeda et al., Vitrectomy for rhegmatogenous or tractional retinal detachment with familial exudative vitreoretinopathy, OPHTHALMOL, 106(6), 1999, pp. 1081-1085
Objective: To examine the anatomic features and surgical indications of fam
iliar exudative vitreoretinopathy (FEVR) complicated with rhegmatogenous or
tractional retinal detachment,
Design: Retrospective noncomparative case series, Participants: Twenty-eigh
t eyes of 25 patients who had either clinically suspected or fully diagnose
d FEVR, Of these, 25 had rhegmatogenous retinal detachment, 2 had tractiona
l retinal detachment, and 1 had tractional retinal detachment plus vitreous
hemorrhage, Interventions: The authors carefully observed the vitreoretina
l interface during surgery, studied the clinical and anatomic features of F
EVR, and then evaluated the surgical results.
Results: The vitreoretinal adhesions were so strong in the peripheral avasc
ular area that iatrogenic retinal breaks easily occurred in 22 of 28 eyes.
In all cases, the bimanual technique with vitreous scissors and forceps was
required to dissect the posterior vitreous membrane from the retinal surfa
ce. The retina was reattached in 24 of 28 cases (85.7%), and visual acuity
improved in 20 eyes (71,4%).
Conclusion: Dissection of the vitreous in the peripheral avascular area is
very difficult in FEVR, and those patients for whom this procedure was not
successfully performed may have a poorer prognosis.
