Abstract

The purpose of our study was to describe features of choroidal naevi as seen on swept source optical coherence tomography angiography (OCTA) and also on en face images derived from structural data from OCTA. A prospective observational cohort study was carried out. Patients attending a specialised choroidal naevomelanocytic with known naevi were imaged with swept source OCTA. Seventy-one eyes of 70 patients were imaged. Forty-three patients and 44 eyes were included. Mean age was 57.7 years (SD 14.9), range 29-81 years. Male to female ratio was 20:23. On OCTA after manual segmentation, naevi could be seen in 47.6% of cases, whereas in the en face images, naevi could be clearly visualised in 79.5% of cases. In OCTA, the superficial and deep capillary plexuses appeared undisturbed as did the outer retinal layer appeared in all cases of flat naevi. In choroidal naevi with mild elevation, the outer retinal layer appeared more susceptible to projection artefacts from overlying retinal vasculature. The choriocapillaris layer showed a fading of the normal homogenous vascular mosaic corresponding to the area of the naevus. In the en face images, even the faintest and thinnest naevi could be visualised in striking detail, and naevi greater than 120 μm thickness appeared darker (p = 0.0034). OCTA presents characteristic changes in the choriocapillaris layers in cases of choroidal naevi. The association of naevus substance appearing darker with increasing thickness may offer a novel prognostic clue. En face structural OCT may allow accurate, detailed measurement of lateral dimensions which could be of value in the monitoring of suspicious naevi.

Attention Score in Context

This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 22 June 2018.
All research outputs
#8,224,163
of 13,118,813 outputs
Outputs from Graefe's Archive of Clinical & Experimental Ophthalmology
#748
of 1,316 outputs
Outputs of similar age
#160,515
of 270,986 outputs
Outputs of similar age from Graefe's Archive of Clinical & Experimental Ophthalmology
#7
of 25 outputs
Altmetric has tracked 13,118,813 research outputs across all sources so far. This one is in the 23rd percentile – i.e., 23% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,316 research outputs from this source. They receive a mean Attention Score of 2.8. This one is in the 36th percentile – i.e., 36% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 270,986 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 31st percentile – i.e., 31% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 25 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 64% of its contemporaries.
