Thirty-three patients with central vein occlusion were evaluated for the effects of scatter xenon arc panretinal photocoagulation. Thirty-four eyes (2 eyes of 1 patient) were randomly divided into a treatment (15 eyes) and a nontreatment group (19 eyes). The average follow-up per eye has been 29 months. The visual prognosis was not significantly better in either group. There was no difference in the development of fundus neovascularisation between groups. None of the patients in the treated group developed rubeosis or neovascular glaucoma. Two patients in the nontreatment group initially had rubeosis and 3 developed it after entry. All 5 involved eyes developed neovascular glaucoma. A significantly greater amount of central retinal capillary drop-out was present in the untreated eyes that developed rubeosis than those untreated eyes which did not. The eyes in the treated group had a similar range of capillary drop-out area, but none of these eyes developed rubeosis or neovascular glaucoma. Panretinal photocoagulation prevented the development of rubeosis and neovascular glaucoma in susceptible eyes.
对33例中心静脉阻塞患者进行了散射氙弧全视网膜光凝治疗效果评估。34只眼（1例患者的2只眼）被随机分为治疗组（15只眼）和非治疗组（19只眼）。每只眼的平均随访时间为29个月。两组的视力预后均无明显改善。两组之间眼底新生血管形成情况无差异。治疗组患者均未发生虹膜红变或新生血管性青光眼。非治疗组有2例患者最初出现虹膜红变，3例在入组后出现。所有5只受累眼均发生了新生血管性青光眼。发生虹膜红变的未治疗眼比未发生虹膜红变的未治疗眼存在明显更多的视网膜中央毛细血管闭塞。治疗组的眼毛细血管闭塞面积范围相似，但这些眼中均未发生虹膜红变或新生血管性青光眼。全视网膜光凝可预防易感眼发生虹膜红变和新生血管性青光眼。
