The posterior precortical vitreous pocket is a premacular liquefied lacuna that is physiologically present in adult eyes. The posterior wall of the pocket consists of a thin layer of the vitreous, and its anterior border is delineated by vitreous gel. This peculiar structure of the premacular vitreous cortex plays a key role in the development of various vitreomacular disorders. In diabetic retinopathy, fibrovascular tissue tends to develop along the outer margin of the pocket, resulting in a ring- or c-shaped structure. Tangential contraction of the posterior wall of the pocket or premacular cortex causes the formation of macular holes. The posterior wall of the pocket serves as a major structural component of idiopathic premacular fibrosis. The concept of the posterior precortical vitreous pocket provides a guideline to manage vitreoretinal disorders occurring in the macular area.
皮质后玻璃体腔是成人眼中生理存在的黄斑前液化腔隙。该腔隙的后壁由一层薄的玻璃体组成，其前缘由玻璃体凝胶界定。黄斑前玻璃体皮质的这种特殊结构在各种玻璃体黄斑疾病的发生发展中起关键作用。在糖尿病性视网膜病变中，纤维血管组织倾向于沿着腔隙的外缘生长，形成环形或C形结构。腔隙后壁或黄斑前皮质的切线收缩会导致黄斑裂孔的形成。腔隙后壁是特发性黄斑前纤维化的主要结构成分。皮质后玻璃体腔的概念为处理黄斑区发生的玻璃体视网膜疾病提供了指导。
