可能會造成RD的Peripheral Retinal Degeneratin
* lattice degeneration (正常人6~10%發生率)
* vitreoretinal tufts
* meridional folds (好發在superonasal)
* enclosed ora bays
* peirpheral excavations
不容易造成RD的Peripheral Retinal Degeneratin
* cobblestone (Paving-stone) degeneration(inferonasal)
* RPE hypertrophy
* RPE hyperplasia
* peripheral cystoid degeneration
Typical peripheral cystoid degeneration (TPCD)
=> 20歲後產生,裂在Outer Plexiform Layer (OPL),比RPCD「多」
(口訣: T-OP → Teaching CR正在手術室OP。主任誇:開得真好,有空多來上刀吧…)
Reticular peripheral cystoid degeneration (RPCD)
=> 裂在Nerve Fiber Layer (NFL),較「少」發生
(口訣: R-NF … Resident-在手術房只會滴水 → No Function…主任說:肉腳!沒事少上來吧)
* Typical degenerative retinoschesis: 1%, 好發在inferotemporal,裂在OPL
reticular degenerative retinoschisis: 1.6%,裂在NFL,易造成bullous RD
