Visual field impairment affects more than 100 million people globally. However, due to the lack of the access to appropriate ophthalmic healthcare in undeveloped regions as a result of associated costs and expertise this number may be an underestimate. Improved access to affordable diagnostic software designed for visual field examination could slow the progression of diseases, such as glaucoma, allowing for early diagnosis and intervention. We have developed Specvis, a free and open-source application written in Java programming language that can run on any personal computer to meet this requirement (http://www.specvis.pl/). Specvis was tested on glaucomatous, retinitis pigmentosa and stroke patients and the results were compared to results using the Medmont M700 Automated Static Perimeter. The application was also tested for inter-test intrapersonal variability. The results from both validation studies indicated low inter-test intrapersonal variability, and suitable reliability for a fast and simple assessment of visual field impairment. Specvis easily identifies visual field areas of zero sensitivity and allows for evaluation of its levels throughout the visual field. Thus, Specvis is a new, reliable application that can be successfully used for visual field examination and can fill the gap between confrontation and perimetry tests. The main advantages of Specvis over existing methods are its availability (free), affordability (runs on any personal computer), and reliability (comparable to high-cost solutions).
全球有超过1亿人受到视野障碍的影响。然而，由于欠发达地区相关成本和专业知识的限制，缺乏获得适当眼科医疗保健的途径，这个数字可能被低估了。改善获得价格合理的用于视野检查的诊断软件的机会，可以减缓诸如青光眼等疾病的进展，实现早期诊断和干预。我们开发了Specvis，这是一个用Java编程语言编写的免费开源应用程序，它可以在任何个人电脑上运行以满足这一需求（http://www.specvis.pl/）。Specvis在青光眼、视网膜色素变性和中风患者身上进行了测试，并将结果与使用Medmont M700自动静态视野计的结果进行了比较。该应用程序还进行了测试内个体差异的测试。两项验证研究的结果均表明测试内个体差异较低，并且对于快速简单地评估视野障碍具有合适的可靠性。Specvis能够轻松识别零敏感度的视野区域，并允许评估整个视野中的敏感度水平。因此，Specvis是一种新型、可靠的应用程序，可成功用于视野检查，能够填补面对面检查和视野计检查之间的空白。Specvis相对于现有方法的主要优点是其可用性（免费）、可承受性（可在任何个人电脑上运行）和可靠性（与高成本解决方案相当）。
