Patients diagnosed with FK were enrolled from three cities in China
between April 2015 and June 2022. The diagnosis was confirmed either by
corneal cultures or corneal biopsy. Patients who were over 65 years old,
had systemic diseases such as diabetes, autoimmune diseases,
thyroid-related diseases, or were pregnant, were excluded. Patients with
bacterial, amebic, or other infections confirmed by culture were also
excluded. A total of 355 patients were included, comprising 212 from
Zhongshan Ophthalmic Center in Guangdong Province, 83 from Xi'an
First Hospital in Shanxi Province, and 60 from Guangxi Zhuang Autonomous
Region People's Hospital in Guangxi Zhuang Autonomous Region. There
were 5 licensed ophthalmologists using standard processing to grade the
image quality. A total of 8697 images were graded as good quality and were
further divided into three datasets: a classification dataset (N=7086,
including 4255 in the training set, 1413 in the validation set, and 1418
in the test set), a segmentation dataset (N=56, including 46 in the
training set and 10 in the test set), and an external validation set
(N=1555, including 1455 to validate the classification model and 100 to
validate the segmentation model).
