Fundus photography is now an established tool for showing early changes in the retinal nerve fibre layer (RNFL). RNFL defects may precede glaucomatous visual field defects by up to five years and any improvement in photography should aid RNFL defect analysis. We have found that the use of an unsharp mask has helped to visualise the RNFL and by using readily available darkroom materials the process of unsharp mask preparation has been simplified.
眼底摄影现已成为显示视网膜神经纤维层(RNFL)早期变化的既定工具。RNFL缺损可能比青光眼性视野缺损早出现长达五年,摄影技术的任何改进都应有助于RNFL缺损分析。我们发现,使用锐化蒙版有助于观察RNFL,并且通过使用现成的暗房材料,锐化蒙版的制备过程已得到简化。
