Predictive models for limbal stem cell deficiency. Newcastle University. Started March 2025.

The problem

Limbal stem cell deficiency (LSCD) is a condition in which the cornea’s regenerative stem-cell population is lost or dysfunctional, leading to conjunctivalisation, neovascularisation, and persistent epithelial defects. Clinical trajectories are heterogeneous, and existing grading systems — while useful — leave substantial uncertainty about which patients will progress, respond to conservative management, or require surgical intervention.

The research question

Can a predictive framework, trained on in-vivo confocal microscopy (IVCM) imaging and clinical metadata, improve the characterisation of disease trajectory at the individual-patient level?

Method

Current work focuses on cohort construction, feature engineering from IVCM, and evaluation of supervised and representation-learning approaches under small-sample constraints and rigorous data-governance protocols. The research is conducted within a UK clinical-research framework with cross-functional collaboration between ML engineering and clinical ophthalmology.

Status

First-year candidate (as of April 2026). Expected completion 2028/29.

Frequently asked questions

What is limbal stem cell deficiency (LSCD)?

A corneal surface disease caused by loss or dysfunction of the limbal stem cells that maintain the corneal epithelium, producing symptoms ranging from photophobia to vision loss.

What dataset does this research use?

IVCM imaging and associated clinical metadata from a UK clinical-research collaboration.
