Recent studies have suggested that diffuse field loss and localized visual field loss in glaucomatous patients may have different pathophysiologic mechanisms. Testing that hypothesis requires that some patients present with purely localized field loss and other patients with purely diffuse loss. This article describes four highly selected patients with elevated intraocular pressures, bilateral damage to the optic nerve head, one eye with a classic glaucomatous visual field defect and in the other eye, in the absence of opacities in the media, a diffuse loss of the visual field. Although purely localized loss is very common, the report illustrates purely diffuse loss in the absence of other causes.
最近的研究表明，青光眼患者的弥漫性视野缺损和局限性视野缺损可能有不同的病理生理机制。要验证这一假设，需要一些患者仅表现为局限性视野缺损，而其他患者仅表现为弥漫性视野缺损。本文描述了四名经过严格挑选的患者，他们眼压升高，视神经乳头双侧受损，一只眼睛有典型的青光眼视野缺损，而另一只眼睛在介质无混浊的情况下出现弥漫性视野缺损。虽然单纯局限性缺损很常见，但该报告说明了在没有其他病因情况下的单纯弥漫性缺损。
