It is generally assumed that successful filtering surgery, by maintaining intraocular pressure at a low level, will protect a glaucoma patient's remaining visual field. We present three patients with chronic open angle glaucoma and typical visual field changes. In each case, filtering surgery was performed because of progressive loss of visual filed and inadequate pressure control. Despite excellent pressure levels after operation, field loss continued in the operated eye. Certain genetic and systemic factors may contribute to further loss of visual field in the presence of normal intraocular pressures. We stress the importance of careful and continuous examination of the visual fields in all glaucoma patients regardless of the response of pressure to treatment.
一般认为，成功的滤过手术通过将眼压维持在较低水平，将保护青光眼患者剩余的视野。我们介绍了三名患有慢性开角型青光眼及典型视野改变的患者。在每例患者中，由于视野逐渐丧失且眼压控制不佳而进行了滤过手术。尽管术后眼压水平良好，但手术眼的视野仍持续丧失。某些遗传和全身因素可能在眼压正常的情况下导致视野进一步丧失。我们强调，无论眼压对治疗的反应如何，对所有青光眼患者进行仔细和持续的视野检查都很重要。
