Abstract

Objective

We aimed to compare the detectability of optic disc drusen (ODD), using various non-invasive imaging techniques, including the novel retro-mode imaging (RMI), as well as to analyze the morphological characteristics of ODD on RMI.

Methods

This study involved 7 patients with bilateral ODD, totaling 14 eyes. Multimodal imaging techniques, including multicolor fundus photography (MC), near-infrared reflectance (NIR), green and blue light fundus autofluorescence (G-FAF and B-FAF, respectively), and RMI were used to examine the eyes. FAF was used as the primary method of identifying ODD, and each method's detection rate was compared by two observers. Quantitative measurements of ODD included the number of ODD visualized by the RMI technique, the perimeter (P) and area (A) of ODD were identified.

Results

The average age of the patients included was 49.28 ± 23.16 years, with 5 of the 7 being men. RMI was able to detect ODD in all cases, with a sensitivity of 100%, compared to MC (sensitivity 60.71%), NIR (sensitivity 60.71%), B-FAF (sensitivity 100%), G-FAF (sensitivity 100%). RMI was the only imaging technique capable of assessing ODD morphology and quantifying ODD.

Conclusions

RMI is a promising imaging modality for diagnosing superficial ODD, providing valuable information on the distribution, location, and size of ODD. We suggest the incorporation of RMI as a complementary tool for diagnosing and monitoring ODD in combination with other multimodal imaging methods.

用于诊断视盘色素沉着的 Retromode 成像:一个病例系列
方法 本研究涉及 7 例双侧视盘色素沉着(ODD)患者,共 14 只眼睛。研究采用了多模态成像技术,包括多色眼底照相(MC)、近红外反射(NIR)、绿光和蓝光眼底自动荧光(分别为 G-FAF 和 B-FAF)以及 RMI。FAF 是识别 ODD 的主要方法,每种方法的检出率由两名观察者进行比较。ODD 的定量测量包括 RMI 技术观察到的 ODD 数量、ODD 的周长(P)和面积(A)。与 MC(灵敏度为 60.71%)、NIR(灵敏度为 60.71%)、B-FAF(灵敏度为 100%)和 G-FAF(灵敏度为 100%)相比,RMI 能够检测出所有病例的 ODD,灵敏度为 100%。结论RMI 是一种很有前途的诊断浅表 ODD 的成像模式,可提供有关 ODD 分布、位置和大小的有价值信息。我们建议结合其他多模态成像方法,将 RMI 作为诊断和监测 ODD 的辅助工具。
