Retinal nerve fibre layer (RNFL) photography is an established and integral tool in the management of ocular hypertensives and glaucoma suspects, and in assessing the management of glaucoma in an ophthalmic practice. When RNFL negatives are viewed for analysis, high-contrast negatives yield the most information. When positive prints are subsequently requested, the RNFL negatives are difficult to print. The use of an unsharp mask facilitates the transfer of all the high-contrast negative density range to the print. The use of an unsharp mask has been simplified so that it is quick and efficient and can be adapted for high-contrast negatives other than RNFL images.
视网膜神经纤维层(RNFL)摄影是管理眼压过高者和青光眼疑似患者以及评估眼科实践中青光眼治疗情况的一种既定且不可或缺的工具。在查看RNFL底片进行分析时,高对比度底片能提供最多信息。当随后需要冲洗正片时,RNFL底片很难冲洗出来。使用模糊蒙板有助于将所有高对比度负片密度范围转印到照片上。模糊蒙板的使用已得到简化,因此快速高效,并且可适用于除RNFL图像之外的高对比度负片。
