A/Prof. Simunovic is actively engaged in research into emerging treatments for retinal disease, visual function and experimental vitreoretinal surgery. If you are seeing A/Prof Simunovic as a patient and are interested in participating in a research project, please discuss this with him at your appointment. If you are a prospective research trainee (pre- or -post-doctoral) interested in working on one of these projects, please see his University of Sydney webpage (

Current Projects

Optogenetics for retinal degeneration

This is a pre-clinical trial aimed at vision restoration in a model of inherited retinal degeneration and is supported by the Sydney Medical School Foundation.

Structure, Function, Gene Therapy and Surgery in Retinal Dystrophies

Hereditary diseases of the retina affect up to 1 in 3,000 individuals and are now the commonest cause of blindness registration in persons of working age. This project is aimed at:

  • Assessing the effects of hereditary retinal diseases on vision and retinal structure in patients with known genotypes.
  • Modelling different modes of surgical delivery of therapeutic substances into the sub-retinal space. ( identifier ACTRN12619001121156).
  • Assessing expression of viral vectors in human retinal explants.

This project is supported by the Foundation Fighting Blindness, USA (


This is a phase III clinical trial of a ciliary neurotrophic factor implant for patients with macular telangiectasia II (MacTel II; identifier NCT03316300). The Sydney arm is being conducted by the Macula Research Group at the Save Sight Institute (

ONL 1204

This is a Phase I trail of ON 1204 in macula-off rhegmatogenous retinal detachment ( Identifier: NCT03780972). ONL 1204 is a first-in-class inhibitor of Fragment Apoptosis Stimulator receptor (Fas)-mediated cell death and has demonstrated protection of multiple retinal cell types in numerous preclinical models of acute ocular injury.
