Research interests: 

Genetic eye disease is a leading cause of blindness among infants, children and adults. Dr Mariya Moosajee is focused on:

  • Understanding the molecular basis of inherited eye disorders, in particular the genetics of retinal dystrophies and ocular maldevelopment such as microphthalmia, anophthalmia, ocular coloboma and anterior segment dysgenesis.
  • Establishing the genotype-phenotype relationship through clinical deep phenotyping studies to identify optimal therapeutic windows and outcome measures for clinical trials, patient risk stratification as significant rates of systemic disease association to ensure the appropriate multidisciplinary clinical pathways for best patient care.
  • Development of novel therapeutic approaches for genetic eye disease including nonsense suppression therapy (ataluren, PTC-derivatives, NB compounds and amlexanox) anti-cell death and antioxidant drugs, and gene therapy using non-viral gene delivery systems including scaffold matrix attachment region (S/MAR) vectors.
