Introduction
The aetiology and pathogenesis is poorly understood
- Attributed to Jain and Johnson's pathogenesis theory
- Believes to be due to the incomplete closure of the choroidal fissure
- The poor development of the sclera and lamina cribrosa causes herniation of ocular tissue and appearance
- The retinal detachment is attributed to the CSF from the subarachnoid space causing rhegmatogenous exudation
- Possibly due to mutations in PAX6 (master control gene of the eye)
Dead Giveaways
Giveaways are mainly in the funuds autofluorescence images as well as the OCT
FAF:
The spoke like radiating vessels evidently seen
OCT:
Retinal detachment seen under the star 
This shows the deep pit from the funnel shaved optic disc excavation
diagnostic features
Visual prognosis is typically poor, and can be co-existing with high RE, amblyopia and strabismus.
30% of the time associated with retinal detachment
If the macular is involved, it is called Macular Capture
For specific terminology, it is known as the Morning Glory Disc if there is no systemic conditions
It is known as Morning Glory Syndrome with systemic signs
These can include midfacial malformations or transphenoidal encephalocele
