对于部分伴有视网膜高度脱离的患者，因其视网膜脱离高度邻近晶状体，直接行

For some patients with high retinal detachment, because their retinal detachment is highly adjacent to the lens, direct vitreous injection may cause high risk of lens damage and retinal tears. Therefore, first we will drain the patient's subretinal fluid, and at the same time Vitreous injection of anti-VEGF drugs further promotes the absorption of subretinal fluid, creating conditions for retinal freezing and laser.

For some patients with a high degree of retinal separation, because the retina is separated from the high proximity of the crystal, direct line glass injection may cause damage to the crystal and cause the risk of retinal fissures, therefore, first of all, we will carry out the patient's under-retina fluid drainage, while the glass cavity injection anti-VEGF drug further promote the absorption of retinal fluid, for retinal freezing and laser conditions.

For some patients with high retinal detachment, the risk of lens damage and retinal hole may be caused by direct vitreous injection because the retinal detachment is highly adjacent to the lens. Therefore, we will first conduct subretinal fluid drainage for patients, and intravitreal injection of anti VEGF drugs will further promote the absorption of subretinal fluid Laser creates conditions.<br>
