[Pars plana vitrectomy in Terson's syndrome].

Pars plana vitrectomy (PPV) was the operation of choice in haemorrhage (Terson's syndrome) in 7 eyes of 5 patients aged 32 to 47 years. The interval between intracranial haemorrhage and PPV varied from 2 to 10 months. Patients after PPV were followed up for 12 to 84 months. The postoperative course was complicated by successfully operated retinal detachment in two eyes where PPV was not safeguarded by cerclage. The final visual acuity 0.7-1.0 was achieved in 6 of 7 eyes (87%); visual acuity of 0.1 in one eye was due to a lamellar defect of the macula. PPV is the treatment of choice in Terson's syndrome with bilateral haemorrhage into the vitreous body and in massive unilateral extravasation with inadequate spontaneous resorption. Cerclage in PPV in TS is according to the authors essential prevention of iatrogenic retinal detachment.
