About

To identify the underlying causes of macular haemorrhages in patients with high myopia
In the eyes found to have macular haemorrhages secondary to choroidal neovascularisation, we hope to identify the risk factors for the development of choroidal neovascularisation in high myopia
To study the functional outcome of these eyes as assessed by visual acuity
To study the morphological outcome of these eyes by clinical assessment (and fundal photography) and fluorescein angiography

Full description

Primary Aims

To identify the underlying aetiologies of macular haemorrhages in myopic eyes
To study the functional and morphological outcome of these eyes with macular haemorrhages 6 months later Secondary Aims
To study the subgroup of eyes with myopic choroidal neovascularisation (CNV), in particular the risk factors for CNV in myopes
To study the subgroup of eyes with macular haemorrhages in the absence of CNV

Plan of investigation:

Patient with myopia (>-6.00DS) presents with loss of central vision
Examination reveals a macular haemorrhage
Investigations
- Refraction
- Axial length*
- Fundus fluorescein angiography
- Indocyanine green angiography*
Determine if a myopic CNV is present or absent
Management of patient: Treatment vs No treatment
- Treatment being
  1. Conventional laser
  2. PDT
Review at 6 months
- BCVA
- Clinical appearance (fundal photo)
- FFA
Review at 12 months
- BCVA
- Clinical appearance
