What Are You Doing In Real Life II

[JU_88]

Sorry to hear about you eye Jim, best wishes with the operation sir!

[Jimbuna]

Thanks guys. I'll report back tomorrow evening after the operation and if I'm still able to see my keyboard

[Jimbuna]

Had the laser procedure carried out and now have to wait a few weeks before the next scan to see if the procedure has been beneficial.

Good excuse to try the Ray Ban knockoffs on for the first time

[Commander Wallace]

Happy you came through it well, Jim. Keep the reading, TV watching and Subsimming to a minimum. Although the Ray ban's are stylish as well, avoid the Sun and UV rays as well.



Keep us posted.

[Jimbuna]

Rgr that matey

[Catfish]

Get well soon, and as said before be careful with bright light. Looks cool

[Rockstar]

Are those the wife's sunglasses?

[Catfish]

^ and i thought it was Jim

(Let's find out if he can still read )

[Mr Quatro]

Now get a Royal Air Force cap for that exposed head of yours and take lots of eye meds the ones they give you are better than the ones at the drug store

[Rockstar]

Leave Jim alone he's healing. In the meantime lets bring in the dancing girls and debauchery while he's down.

Now why didn't I think of that ?

[Jimbuna]

Crazy buggas

[Sailor Steve]

The operation must have been a success. You still look the same.

Good luck with that. Or have you forgotten that Jim's the only thing keeping me under control?

SOUNDS LIKE DIABETIC MACULAR EDEMA??!!

 

Photocoagulation: thermal effect. Lesions are caused by an increase in tissue temperature, causing vaporization of liquids within and outside tissues and denaturalizing proteins, resulting in cellular death (apoptosis). Lasers of this kind are called photocoagulators, some of which are of argon (514.4 green and 488 blue-green nanometers) and krypton (647.1 red nanometers), which require a water refrigeration system. Currently, the most commonly used are double-diode (532 nanometers) and double-YAG (532 nanometers), which do not require cooling systems. 2) Disruption: electromechanical effect. These lasers use a burst of optical pulses of high power and short duration, achieving ionization of the tissue, forming plasma that expands at high temperature, which causes an acoustic shock wave that breaks the target tissue. Lasers of this type are called photodisruptors and Neodimio YAG (Yttrium-Aluminum-Garnet) operated with a longitudinal wave of 1064 nanometers is the one most commonly used. Its usefulness is in carrying out a capsulotomy after opacification following cataract surgery, and peripheral iridotomy to prevent risks of acute angle-closure glaucoma.
3) Photochemical, in which the lasers are used to alter the chemical composition of the target tissue, producing a molecular alteration of the cells subjected to a prior photosensitization. This type of treatment is called photodynamic therapy. In this type of laser, the treatment is carried out by photosensitization of the tissues, using photosensitizing agents like verteporfin (with a laser light absorption peak of 689 nm), which binds to the lipoproteins LDL-cholesterol. The activation is done by a non-thermal diode laser of 689 nm for 83 seconds, giving a dose of 50 jules/cm2 luminous light intensity of 600mW/cm3. Once activated, verteporfin radicals release oxygen, a process that alters the membranes of endothelial cells of the ocular blood vessels. This produces a platelet aggregation and forms a thrombus, resulting in an occlusion of the vessels. This technique is currently used in the treatment of exudative AMD (age related degeneration).
4) Photodecomposition. This is the result of the interaction of the laser with the tissues, which emits ultraviolet light at the target tissue. In this case, the laser photons are absorbed at the molecular level, resulting in fragmentation of the molecules. They emit ultraviolet radiation of 193 nanometers in pulses of 10 nanoseconds and the emitted radiation destroys molecular unions forming a volatile phenomenon called photodecomposition. The Excimer lasers (Argon - Fluoride) used in refractive surgery sculpt the corneal stroma using the photoablation.
Of the lasers described above, the treatment of DR and the DME appearing there is carried out with photocoagulator lasers. The first of their type used were argon and krypton, which were very cumbersome owing to the need for water cooling facilities. These have been replaced by the so-called solid lasers, which use diode or YAG, doubled to a produced radiation of 532 nanometers.
One type of laser also used in DME is the diode of 810 nanometers and acts in micropulses of 0.1 ms duration.
