[Late Retinal Complications in Former Preterm Infants with Regressed ROP].

BACKGROUND

The purpose of this study is to evaluate late retinal complications in former preterm infants with regressed stages of acute retinopathy of prematurity (ROP).

PATIENTS AND

METHODS

Between 1995 and 2002 a consecutive series of 15 patients (16 eyes) with loss in visual acuity were examined. Gestational age was < 32 weeks, birth weight < 1500 g. The reason for visual disturbances was: RD (n = 14), vitreous haemorrhage (n = 3) and posterior vitreous detachment (n = 1).

RESULTS

Two eyes recovered spontaneously. Surgery was performed in 14/16 eyes, with a pars plana vitrectomy (n = 14), or buckling procedure (n = 2). Four eyes with a severe form of regressed ROP needed multiple procedures for reattachment At last follow-up in 13/14 (93.0 %) eyes the retina was completely attached. Visual acuity ranged from light projection to 20/25.

CONCLUSIONS

Former premature patients with vitreoretinal changes due to regressed ROP may develop vitreous traction and subsequent late-onset retinal detachment. Surgery with primary vitrectomy technique in eyes with retinal detachment can remove the vitreoretinal adhesions and is an effective treatment technique. In eyes without retinal detachment the natural course can be awaited.
