Article Abstract
The incident light reflected from the cornea is rich in information about the human surroundings, and these reflected rays are imaged by the camera, which can be used for research on human consciousness and gaze analysis, and produce certain help in the fields of psychology, human computer interaction and disease diagnosis. However, limited by the low corneal reflection ability, when a high-definition camera captures corneal reflecting rays, a large amount of color and texture interference from the iris can seriously contaminate the corneal reflection images, resulting in low usability and ubiquity of corneal reflection images. In this paper, we propose a corneal reflection image extraction method with multiple eye images as input. We align the iris regions of multiple eye images with the help of iris localization method, and by comparing multiple iris regions, we obtain the complementary iris regions, so that the iris interference in the corneal reflection region can be stripped completely. A large number of experiments have demonstrated that our work can effectively mitigate iris interference and effectively improve the quality of corneal reflection images.

Objective: To evaluate the therapeutic efficacy and inflammatory modulatory effects of combined 0.01% atropine eye drops and orthokeratology (OK) lenses in controlling myopia progression among adolescent patients.
Methods: This retrospective study analyzed clinical data from 90 adolescent patients (90 eyes) with myopia treated from April 2021 to June 2023.

To investigate corneal deposits in a patient undergoing long-term chlorpromazine therapy using confocal microscopy with the HRT II Rostock Corneal Module. We reported a 45-year-old woman with a 7-year history of chlorpromazine therapy presented with bilateral photophobia and a 4-year history of gradual-onset blurred vision. Slit-lamp examination revealed yellowish deposits in the corneal endothelium and Descemet's membrane.

Keratoconus is a bilateral non-inflammatory ectatic disease of the cornea, with an asymmetrical evolution, that occurs in young people during puberty, progressing during the second and third decades and stabilizing around the age of 40. It is characterised by an insidious and progressive thinning of the cornea, myopia and astigmatism, which lead to a decrease in visual acuity. Slit-lamp examination findings in the early stages of keratoconus may appear normal.

Purpose: Limbal stem cell deficiency (LSCD), a sight-threatening condition, is caused by dysfunction of the limbal stem cells (LSCs) which maintain the corneal epithelium. An effective treatment of LSCD is the transplantation of ex-vivo cultured LSCs from the patient's healthy other eye (in unilateral cases) or a donor eye (in bilateral cases) to the affected eye. Here we identify and quantify diagnostic and monitoring criteria for the recovery of the corneal epithelium post-LSC transplant using cellular images.

Background: Corneal dystrophies are inherited disorders that can lead to significant visual impairment and often require surgical intervention in advanced stages. Fuchs endothelial corneal dystrophy (FECD) is the most frequently diagnosed type in Western countries and remains a leading global indication for corneal transplantation. In contrast, non-Fuchs dystrophies represent a diverse group of less common entities, each with distinct clinical features, surgical considerations, and regional variations in incidence and management.
