Cysts of the Pars Plana Ciliaris

Giant pars plana cysts and a diagnostic approach to peripheral retinal elevation with the assistance of multimodal imaging

“…Pars plana cysts are typically secondary to degeneration and are associated with cystoid degeneration and retinoschisis 5 11 13. Rarer causes of pars plana cysts include infection, trauma/globe rupture or multiple myeloma 4. On funduscopy, giant pars plana cysts may mimic a retinal break or a rhegmatogenous retinal detachment which was reported in a similar case by Braceros et al 14.…”

“…Formation of pars plana cysts commonly result from the separation of the non-pigmented ciliary epithelium and pigmented epithelium or less frequently from the coalescence of vacuoles within the non-pigmented epithelium with adjacent cells 11. Histology slides have observed traction from vitreous strands and zonular fibres extending to pars plana cysts 4 11. This traction is the most likely mechanism for the formation of pars plana cysts and retinal breaks/detachments,11 and their predominance to be located temporally corresponds with the widest portion and strongest attachment of the vitreous base.…”

“…While it is generally accepted that pars plana cysts are not directly related to rhegmatogenous retinal detachment, retinal holes have been observed in several large pars plana cysts 11 12. Research by Grignolo et al observed interactions between pars plana cysts and a pre-existing retinal detachment in cases of massive vitreous retraction 4. During these cases, all partitions between the cysts disappeared, followed by the pigment epithelium detaching from the ora serrata which subsequently created a direct communication between the cystic cavity and an existing retinal detachment.…”
