研究证明,氩激光光凝可减轻老年性黄斑变性和中心凹外的视网膜下新生血管膜所致的视力障碍,因此,必须及早发现老年人中能治疗的视网膜下新生血管膜。视力减退和其他症状常有助于判断视网膜下新生血管膜发生与否。有新生血管膜者,视力急剧下降(以日计算),而无新生血管膜和干性老年性黄斑变性者,则缓慢进行(以月计算)。视力≤0.05者,可能有视网膜下新生血管膜的发生,若此膜发生干中心凹以外,即属于可能实施氩激光治疗者,其中心视力减退不著。由于视网膜下
Studies have shown that argon laser photocoagulation can reduce the age-related macular degeneration and subfoveal subretinal neovascular membrane caused by visual impairment, therefore, we must early detection of the elderly can be treated with subretinal neovascular membrane. Vision loss and other symptoms often help determine the occurrence of subretinal neovascular membrane. Those with neovascular membranes experienced a sharp decline in visual acuity (calculated in days), while those without neovascular membranes and dry age-related macular degeneration were slowly (in months). Visual acuity ≤ 0.05, retinal neovascular membrane may occur, if the film occurs outside the fovea, which may belong to the possible implementation of argon laser treatment, the central vision loss refuses. Due to subretinal
