The visual prognosis in eyes with and without macular pathology, after treatment of the primary, peripheral retinal vascular malformation (PRVM) was studied. Seventeen patients (16 eyes) underwent treatment of the PRVM with laser/cryopexy. In 13/17 eyes (76.4%) associated macular pathology included, macular oedema and/or hard exudates (5 eyes), epiretinal membrane (2 eyes), exudative retinal detachment (3 eyes), vascular malformation in macula (2 eyes) and macular hole (1 eye). Initial visual acuity ranged from counting fingers 20/200. After treatment of the primary lesion, the visual acuity improved in five eyes, decreased in one eye and remained stable in 7 eyes. Of the four eyes without macular involvement, the vision improved after treatment in two eyes and remained stable in two eyes. We conclude that a variety of macular lesions can reduce central vision in eyes with PRVM. After treatment of only the primary lesion, the macular lesions also show changes. Visual acuity can improve or remain stable after treatment of the primary lesion. Rarely, the vision can decrease.
我们研究了原发性周边视网膜血管畸形（PRVM）治疗后，存在和不存在黄斑病变的眼睛的视觉预后。17例患者（16只眼）接受了PRVM的激光/冷冻治疗。13/17只眼（76.4%）伴有黄斑病变，包括黄斑水肿和/或硬性渗出（5只眼）、视网膜前膜（2只眼）、渗出性视网膜脱离（3只眼）、黄斑区血管畸形（2只眼）和黄斑裂孔（1只眼）。初始视力范围从眼前指数到20/200。原发性病变治疗后，5只眼视力提高，1只眼视力下降，7只眼视力保持稳定。在4只未累及黄斑的眼中，治疗后2只眼视力提高，2只眼视力保持稳定。我们得出结论，多种黄斑病变可降低PRVM患者的中心视力。仅治疗原发性病变后，黄斑病变也会出现变化。原发性病变治疗后视力可提高或保持稳定。视力很少会下降。
