(1) Serous detachment of the retina |
| Small yellow-white lesion (neovascular membrane) surrounded by retinal detachment and/or a small amount of haemorrhage. In some instances, these lesions are surrounded by variable numbers of hard exudates. |
(2) Large detachment of the retinal pigment epithelium |
| Large detachment of the retinal pigment epithelium associated with choroidal neovascular membrane. |
2 Typical lesion |
(1) Subretinal haemorrhage |
| Dome-shaped haemorrhagic detachment of the sensory retina and retinal pigment epithelium in and around the macula. Vitreous haemorrhage occasionally occurs when the amount of subretinal haemorrhage is large. |
(2) Disciform lesion |
| This lesion is the typical disciform lesion of the disease. Large yellowish-white disciform lesions in the macular area are associated by the haemorrhage, retinal detachment, and hard exudates. Extensive detachment of the retinal pigment epithelium is also occasionally observed. |
3 Scar stage |
| There are variations in this stage from simple atrophic lesions to formation of white or grey thickened scars. |
