Prof. Mariya Moosajee

Professor Mariya Moosajee is an academic ophthalmologist specialising in genetic eye diseases that spans the front to the back of the eye. She undertakes research into the genes that cause eye diseases and develops novel therapies. Mariya has a research lab at University College London Institute of Ophthalmology and the Francis Crick Institute in London.

She also undertakes studies looking at high resolution clinical signs in the eyes of patients using imaging tests to map disease progression and identify outcome measures for clinical trials.

Specialisms

Professor Moosajee has an expertise in genetic eye disease.

Qualifications and training

Professor Moosajee graduated with First Class Honours in Biochemistry and Molecular Genetics in 2000, Medicine (MBBS) in 2003, and was awarded her PhD in Molecular Ophthalmology in 2009 all from Imperial College London. Her current clinical focus is providing a genomic service for children affected with all forms of non-syndromic and syndromic genetic eye disease at GOSH. She sees children and adults making it easy for teenagers to transition to adult services but also for the whole family to be considered together.

Research interests

Professor Moosajee undertakes detailed clinical studies using state-of-the-art imaging tools to further our understanding of the natural history of patients with genetic eye disease, this helps to identify outcome measures to apply to clinical trials to monitor responses to treatments. Professor Moosajee also leads her own research group at the UCL Institute of Ophthalmology and the Francis Crick Institute, and her specialist interest is understanding the genetic basis of inherited eye diseases that can affect children from birth or in early childhood. This permits the identification of potential therapeutic targets, for which she then develops novel treatment strategies for a wide range of genetic eye disorders.
