Anterior vitreoretinal proliferations are frequent sequelae of retinal detachment repair and severe trauma. Cellular proliferations can form membranes extending anteriorly from the peripheral retina. These membranes have the capability to contract and may lead to detachment of both the peripheral retina and, in more advanced stages, the ciliary body. Because the vitreous base and vitreous remnants are leading structures for cellular proliferation, complete removal of the anterior vitreous base in particular is important in cases of severe trauma or complicated retinal detachment. In 11 cases of anterior proliferative vitreoretinopathy examined histopathologically, we found overlying membranes and cellular infiltration of the vitreous in close correlation with the amounts of vitreous remnants present. Visualization of the peripheral retina and pars plana can rarely be accomplished in the presence of the crystalline lens or pseudophakia. Therefore, the removal of the anterior vitreous is often incomplete. To achieve complete dissection of the anterior vitreous, we remove even a clear lens during the first surgical intervention in selected cases.
玻璃体视网膜前部增殖是视网膜脱离修复和严重创伤常见的后遗症。细胞增殖可形成从周边视网膜向前延伸的膜。这些膜具有收缩能力，可能导致周边视网膜脱离，在更晚期还会导致睫状体脱离。由于玻璃体基底部和玻璃体残余物是细胞增殖的主要结构，因此在严重创伤或复杂性视网膜脱离病例中，尤其重要的是彻底切除前部玻璃体基底部。在11例接受组织病理学检查的前部增殖性玻璃体视网膜病变病例中，我们发现覆盖的膜和玻璃体的细胞浸润与存在的玻璃体残余物数量密切相关。在存在晶状体或人工晶状体的情况下，很少能实现周边视网膜和平坦部的可视化。因此，前部玻璃体的切除往往不彻底。为了实现前部玻璃体的完全剥离，我们在某些选定病例的首次手术干预中甚至会摘除透明晶状体。
