※ 引述《SkySlaughter (※天空屠殺者※)》之銘言:
: 裂孔性視網膜剝離(Rhegmatogenous retinal detachment, RRD):裂孔性視網膜剝離
: 發生在視網膜裂孔形成的基礎上。液化的玻璃體經裂孔進入視網膜感覺層與色素層(RPE)
: 之間,形成視網膜剝離。多見於老年人、高度近視和眼外傷後;無晶狀體眼和偽晶狀
: 體眼、一眼有視網膜剝離或有家族史,都是高危險群
: 希望有眼科原文書的幫忙申覆一下這一題
: 本題選項 (C)萎縮性視網膜裂孔亦可能造成視網膜剝離
: 因此建議更正答案為 (B) (C)
: 附議者請推一下 謝謝

Chapter 10. Retina
Diseases of the Peripheral Retina
Rhegmatogenous Retinal Detachment
The
most common of the three major types of retinal detachments is
rhegmatogenous retinal detachment. The characteristics of a rhegmatogenous
detachment are a full-thickness break (a "rhegma") in the sensory retina,
variable degrees of vitreous traction, and passage of liquefied vitreous
through the sensory retinal defect into the subretinal space. A spontaneous
rhegmatogenous retinal detachment is usually preceded or accompanied by a
posterior vitreous detachment. Myopia, aphakia,
lattice degeneration, and
ocular trauma are associated with this type of retinal detachment. Binocular
indirect ophthalmoscopy with scleral depression (Figures 2–16 and 2–18)
reveals elevation of the translucent detached sensory retina. A careful
search usually reveals one or more full-thickness sensory retinal breaks such
as a horseshoe tear,
round atrophic hole, or anterior circumferential tear
(retinal dialysis). The location of retinal breaks varies according to type;
horseshoe tears are most common in the superotemporal quadrant, atrophic
holes in the temporal quadrants, and retinal dialysis in the inferotemporal
quadrant. When multiple retinal breaks are present, the defects are usually
within 90 degrees of one another.
申覆理由:根據國考指定用書,RRD為最常見之retinal detachments類型,且臨床表現據
課文敘述,lattice degeneration和round atrophic hole均有,並未提及何者比率最高。
建議更改為B,C均給分。
