![]() The progressive loss of elasticity eventually results in separation of the vitreous from the retina (Figure 2a). In the course of time the collagen fibrils harden, sometimes leading to perception of the mobile dots and threads known as muscae volitantes or “floaters” ( e1). Physiological degeneration of this vitreous scaffold has been demonstrated as early as the first few years of life ( e3, e4). The vitreous is made up almost entirely (98%) of water and is stabilized by collagen fibrils that extend into the superficial (internal) layers of the retina ( 1, e2). The most common cause of rhegmatogenous retinal detachment is degeneration of the vitreous body. Much less frequent again is exudative retinal detachment where the underlying cause is a barrier dysfunction, for example in the case of intraocular tumors or exudative vascular diseases.In the far less common tractional form, the retina is pulled away from the substrate by cord-like scars, e.g., fibrosing proliferation membranes in diabetic retinopathy.The most frequent is the rhegmatogenous form of detachment, in which a retinal tear allows liquefied vitreous humor to penetrate under the retina (Figure 1).Three forms of retinal detachment are distinguished: The separation of the two layers takes place within the fissure formed by the invagination of the optic cup ( e1). Retinal detachment is the term used to describe detachment of the neurosensory retina from the underlying membrane, the retinal pigment epithelium. In all such cases, an ophthalmologist must be consulted at once. The earlier the patient is seen by an ophthalmologist, the greater the chance that the macula is still attached, so that visual acuity can be preserved.Ĭonclusion: Rhegmatogenous retinal detachment is among the main emergency indications in ophthalmology. Vitrectomy is followed by lens opacification in more than 70% of cases. Anatomical success rates are in the range of 85% to 90%. The treatment consists of scleral buckle, removal of the vitreous body (vitrectomy), or a combination of the two. Rhegmatogenous retinal detachment is an emergency, and all patients should be seen by an ophthalmologist on the same day that symptoms arise. Persons in the sixth and seventh decades of life are most commonly affected. Epidemiologic studies have identified myopia and prior cataract surgery as the main risk factors. Results: Rhegmatogenous retinal detachment typically presents with the perception of light flashes, floaters, or a “dark curtain.” In most cases, the retinal tear is a consequence of degeneration of the vitreous body. Method: Selective review of the literature. Without treatment, blindness in the affected eye may result. It just may not the issues here.Īnd pardon me if I said something wrong or rude English is not my main tongue.Background: Rhegmatogenous retinal detachment is the most common retinological emergency threatening vision, with an incidence of 1 in 10 000 persons per year, corresponding to about 8000 new cases in Germany annually. None have work so far.Īnyway, thanks for your assist. Still with the new hard-drive, I tried to install Windows 8.1, with the driver download from the Official HP Driver & Software Download. No issues were found, at least with the audio & video through DisplayPort. Too make sure It wasn't just what live USB would do, I do an installation (on the new hard-drive, not the one with Windows 10) of each distros to the notebook. ![]() No config needed as the only thing to do is plug the adapter to the notebook and all are done. 3 different Linux distro (Ubuntu, Linux Mint, Elementary OS). I have tried change the hard-drive then perform h*ckintosh to get MacOS, A bit pain in the *ss first, then, with a few config, it work just fine. Well, I mean, i use the whole setup (Folio 9470m - adapter - HDMI cable - TV) with another OS (still with this very laptop) and there is full video and audio through DisplayPort adapter, so maybe it's not cable fault?
