University of Malta PhD Research Highlights Diabetic Retinopathy at European Ophthalmology Congress

Why the European Society of Ophthalmology Congress Matters for Ophthalmic Research

The European Society of Ophthalmology (SEOM) Congress is one of the leading international forums for the latest advances in eye care. Held every year in a different European city, the congress draws clinicians, scientists, and industry experts from across the continent. For researchers, the event provides a platform to showcase cutting‑edge studies, engage with peers, and spark collaborations that can elevate a project from laboratory discovery to clinical application.

In June 2025, the SEOM Congress in Lisbon presented a full slate of oral presentations, poster sessions, and keynote lectures that highlighted breakthroughs in retinal imaging, gene therapies, and biomarker discovery. University of Malta researchers were prominently featured, underscoring Malta’s growing reputation as a hub for biomedical innovation.

Dr Muhaiyo Bartolo’s Oral Presentation: A Spotlight on Diabetic Retinopathy

Specialist resident Dr Muhaiyo Bartolo, who practices at Mater Dei Hospital and pursues a PhD in Applied Biomedical Science, delivered an oral talk entitled “Differentially Expressed Genes of Human Lens Epithelial Cells in Different Stages of Diabetic Retinopathy.” The session focused on deciphering molecular changes in the eye’s anterior segment that correlate with the progression of diabetic retinopathy (DR).

Key Findings from the Study

• RNA sequencing of lens epithelial cells isolated from cataract surgery specimens revealed distinct gene expression profiles across the stages of DR.
• Genes associated with inflammation, angiogenesis, and apoptosis showed significant up‑regulation in advanced retinopathy.
• Preliminary data suggest potential biomarkers that could predict disease severity earlier than traditional imaging methods.
• The research also identified novel therapeutic targets that may interrupt pathological pathways before irreversible vision loss occurs.

Methodological Highlights

Dr Bartolo’s approach blended next‑generation sequencing with rigorous bioinformatic analysis. By obtaining samples directly from patients undergoing cataract surgery, the study ensured that the tissue was clinically relevant. Collaborative efforts with the Medical University of Bialystok, Poland, added a metabolomic dimension, examining aqueous humour composition to complement the genomic data.

University of Malta’s Role in Supporting Early‑Career Researchers

Dr Bartolo’s work exemplifies how the University of Malta nurtures research at the intersection of clinical practice and basic science. Faculty mentors—Prof. Rosienne Farrugia, Prof. Jean Paul Ebejer, and Mr. Franco Mercieca—provide multidisciplinary oversight, ensuring that research questions stay grounded in patient care while adopting state‑of‑the‑art methodologies.

The TESS Scholarship program has partially funded Dr Bartolo’s PhD, illustrating the university’s commitment to providing financial support for high‑impact projects. Additional resources include access to the university’s advanced sequencing core, bioinformatics workshops, and a network of international collaborators spanning Europe and beyond.

How to Translate Lab Findings into Clinical Practice

For researchers aiming to move from bench to bedside, the following steps are pivotal:

1. Validate biomarkers in a larger, independent cohort. Prospective studies confirm reproducibility across diverse populations.
2. Engage with regulatory bodies early. Understanding the path for diagnostic assays or therapeutic devices saves time and resources.
3. Partner with industry. Private companies can accelerate the development of companion diagnostics or drug candidates.
Communicate findings to clinicians. Clear, actionable data helps physicians integrate new insights into routine care.

What Researchers and Students Can Learn from This Example

• Interdisciplinary collaboration is essential; combining genomics, metabolomics, and clinical observation enhances relevance.

• Early participation in major conferences builds visibility and opens doors for funding and joint projects.

• Funding mechanisms such as scholarships and institutional grants can sustain long‑term studies that may not attract immediate industry interest.
