※ 引述《SkySlaughter (※天空屠杀者※)》之铭言:
: 裂孔性视网膜剥离(Rhegmatogenous retinal detachment, RRD):裂孔性视网膜剥离
: 发生在视网膜裂孔形成的基础上。液化的玻璃体经裂孔进入视网膜感觉层与色素层(RPE)
: 之间,形成视网膜剥离。多见於老年人、高度近视和眼外伤後;无晶状体眼和伪晶状
: 体眼、一眼有视网膜剥离或有家族史,都是高危险群
: 希望有眼科原文书的帮忙申覆一下这一题
: 本题选项 (C)萎缩性视网膜裂孔亦可能造成视网膜剥离
: 因此建议更正答案为 (B) (C)
: 附议者请推一下 谢谢

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:根据国考指定用书,RRD为最常见之retinal detachments类型,且临床表现据
课文叙述,lattice degeneration和round atrophic hole均有,并未提及何者比率最高。
建议更改为B,C均给分。
