简要介绍:

Retinal vein occlusion (RVO) is a common cause of visual loss in the UnitedKingdom.It is an obstruction of the retinal venous system by thrombus formation and mayinvolve the central, hemi-central or branch retinal vein.1-3 Thrombus formation may be the primary cause but other possible causes are external compression or disease of the vein wall e.g. vasculitis. Retinal vein occlusions are the second commonest cause of reduced vision due to retinal vascular disease 4, 5 with BRVO occurring 2-3 times as common as CRVO.6, 7 In the Australian population study the incidence was 0.7% at 49-60yrs and 4.6% at 80yrs.7 It is currently estimated from pooled data from 15 population studies from that there are about 520 new cases per million population of RVO.8 These include 442 and 80 per million of BRVO and CRVO respectively.It typically occurs in middle aged and elderly patients (i.e. over age of 50 years) with equal sex distribution in both branch retinal vein occlusion (BRVO) and central retinal vein occlusion (CRVO). CRVO is classically characterised by disc oedema, increased dilatation and tortuosity of all retinal veins, widespread deep and superficial haemorrhages, cotton wool spots, retinal oedema and capillary nonperfusion. In less severe forms the disc oedema may be absent. BRVO has similar features except that they are confined to a portion of the fundus. In view of the significant ophthalmological and medical consequences of retinal vein occlusion,these guidelines promote a good standard of practice and the achievement of bestvisual and medical outcome.
