Retinal detachment in left eye.
Retinal detachment is a detachment of the retina proper from the underlying pigmented choroid, and occurs in a number of settings:
- tractional: inflammatory or post traumatic fibrous bands in the vitreous ; also seen in sickle cell disease.
- exudative: fluid accumulating in the subretinal space secondary to hypertension, central retinal venous occlusion, vasculitis, papilledema or tumour.
- post operative: vitreous fluid accumulates in the subretinal space via a hole in the retina (rhegmatogenous RD)
- rhegmatogenous RD: (from rhegma meaning a fissure or fracture) can also be seen in ocular trauma
