We read the article by Fung et al.
1
The authors have proposed that this entity should be called a “focal scleral nodule.”
Fung et al have previously also suggested that the lesion has a component of scleral
collagen based on the hyperautofluorescence of the lesion.
2
We would like to reiterate comments from a recent article we authored earlier this
year entitled, “Solitary idiopathic choroiditis’ or a tumor of scleral origin: A case
report based hypothesis.”
3
In this article, we suggested that this pathology is more likely to be a nodular
mass of scleral origin based on the OCT, intense hyperreflectivity on infra-red imaging,
and magnetic resonance imaging of the lesion. In our article, we were reluctant to
call this entity a sequelae of posterior scleritis as suggested by Fung et al.
2
We would like the authors to comment on this based on the current large series that
they have published. We congratulate the authors on collating such a large series
of cases (63 cases) of this rare entity.

- In BriefWe thank Chawla and Kumar for their interest in our work, and congratulate the authors for their recent case report in which they used multimodal imaging including swept-source OCT to identify the scleral location of what was then known as solitary idiopathic choroiditis.1 We first described these lesions as emanating from the sclera rather than the choroid in our 2013 series of 10 cases imaged with enhanced-depth imaging OCT.2 It is only more recently, however, that we have accumulated a sufficient number of further cases (n = 63) over an extended period of time (up to 25 years) to feel confident in renaming this entity “focal scleral nodule” (FSN).
