Ghost cell glaucoma
Glaucoma
Key Points
- •Ghost cell glaucoma occurs 1–3 weeks after vitreous hemorrhage when degenerated RBCs (rigid, spherical, khaki-coloured) pass through a disrupted hyaloid face into the AC and block the TM
- •The hallmark finding is khaki/tan-coloured cells in the anterior chamber - NOT red like fresh hyphema; they may form a khaki pseudo-hypopyon
- •It is an open-angle mechanism - ghost cells physically obstruct the TM because they are rigid and non-deformable (unlike flexible fresh RBCs)
- •Pars plana vitrectomy is the definitive treatment - removes the source of ghost cells (vitreous hemorrhage) and clears the AC
- •In sickle cell patients, avoid acetazolamide (promotes sickling) and consider early surgical intervention
