Presented at: Association for Research in Vision and Ophthalmology meeting; May 2011; Fort Lauderdale, Fla. Salvetti P, Rosen JM, Reichel E. [healio.com]
In this presentation, Dr. Harper discusses about various retinal conditions where laser can be used. Lecturer: Dr. [cybersight.org]
“Focal” laser is presently the treatment of choice for diabetic macular edema. "Focal" Laser Treatment to Treat Microaneurysms A small lens is placed on the surface of the eye. [retinaeyedoctor.com]
Mean best-corrected visual acuity increased, on average, by about 9 letters by 3 months, and no study reported a decrease in acuity below presentation. [journals.lww.com]
As a result, new vessels do not develop and any already present may go away. The results of scatter laser are usually apparent after a few weeks. The main risk of laser treatment is a burn to the fovea, which could permanently damage central vision. [retinadoctor.com.au]
Eyes
- Retinal Pigmentation
Recent experimental research with new laser devices using much shorter pulse duration has shown that photoreceptor damage can be greatly reduced and the retinal pigment epithelium selectively targeted, hence the term selective retinal pigment epithelium [clinicaltrials.gov]
No retinal complications were observed with the various forms of NRT used, but six patients in two studies with micropulse laser experienced pigmentary changes in the retinal pigment epithelium attributed to excessive laser settings. [journals.lww.com]
It is a very high-energy bright light that, when directed and focussed on to a retina, is absorbed by the retinal pigment epithelium (RPE). [retinadoctor.com.au]
Microfractures within this layer, while enabling migrating cells of various kinds to penetrate into the inner collagenous zone, did not prevent complete regeneration of the retinal pigment epithelium (RPE). [jamanetwork.com]
Laser treatment causes thermal damage, particularly at the level of the retinal pigment epithelium (RPE). [healio.com]
- Retinal Scar
Silicone oil may be used if the retina has been detached for a long time or retinal scarring is present. Laser or freezing treatment is used to seal the retinal tears. [visioneyeinstitute.com.au]
Trauma and Retinal Scar derekl: I was hit in the eye as a child 30 years ago, resulting in a torn retina and subsequent scar, leaving a large center blind spot. [my.clevelandclinic.org]
Since, the temperature rise is insufficient to cause ancillary damage to the surrounding retinal tissue it minimizes scarring to the extent that laser spots are generally undetectable on ophthalmic and angiographic examination. [12] The other development [ijo.in]

Laser Treatment What to Expect Modern retinal surgery has benefited enormously from the introduction of laser treatments. The vast majority of applications to retinal surgery involve the use of lasers, which produce visible light. [retinaldiagnostic.com]
A repeat treatment is necessary in some patients. Although this treatment shows some promise, it has not yet been proven to be effective in a clinical trial. [njretina.com]

Prognosis
Treatment and prognosis If a retinal tear is diagnosed promptly before it progresses to retinal detachment, the prognosis is extremely good. Retinal tears are typically treated with laser or a freezing procedure ( cryotherapy ). [asrs.org]
Until the early 20th century, the prognosis for rhegmatogenous retinal detachment was very poor, and no effective treatments were available. [en.wikipedia.org]
Without knowing more details about your vision, surgery, and nature of detachment, I can’t address your question regarding your visual prognosis. janophelia: I had a detached retina reattached recently. [my.clevelandclinic.org]
Etiology
CSCR remains an idiopathic disorder without a definitive etiology. Many cases of CSCR resolve after a period of observation without any treatment. [nationalretina.com]

The pathophysiology of CSC has, been thought to involve multiple etiologies and mechanisms that ultimately lead to widespread hyperdynamic and hyperpermeable choroidal circulation. [33], [34] The conventional laser treatment debrides the RPE at the site [ijo.in]

Prevention

Laser treatment can often prevent severe vision loss by making these new vessels disappear. [nylasergroup.com]
If, however, the retina has torn but has not yet detached, laser can be done to prevent the retina from detaching. [iowaretina.com]
