In the name of Allah
to know the principle of goniolens we
must know some important information.....
- There is an angle called critical angle which need rays come frommedia of high refractive index to media of low refractive index at this angle no refraction occur.
- When rays come from the angle between cornea and iris outward to air as it has total internal reflectionas there is critical angle so don't released to air .
- Total internal reflection as rays fall with angle is more than critical angle. - corneal R.I = 1.38 - Air R.I = 1.00 - Goniolens eliminates the total internal reflection by replacing the cornea-air interface by a new geniolens-airinterface that has higher R.I (n=1.50) than that of the cornea and the tear.
-uses :- used for viewing the anterior chamber angle of the eye for evaluation, management and classification of normal and abnormal angle structures which is important in glaucoma management and evaluation.
It is movable muco-cutaneous fold covering anterior surface of eye globe.
Upper eye lid is more movable than lower eye lid as it have levator palpebrae superioris muscle and Muller's muscle .
The upper eyelid skin crease (superior palpebral furrow) is approximately 8-11 mm superior to the eyelid margin and is formed by the attachment of the superficial insertion of levator aponeurotic fibers (8-9 mm in men and 9-11 mm in women).
-The palpebral fissure is that empty space between the upper and lower eyelid margins when the eyelids are open (that is, the space between the eyelids that allows you to see your eyeball and your eyeball to see the world).
From those around I hear a cry
A muffled sob, a hopeless sigh,
I hear their footsteps leaving slow,
And then I know my soul must Fly!
A chilly wind begins to blow,
Within my soul, from Head to toe
And then, Last Breath escapes my lips,
It’s time to leave. And I must Go!
So, it is True (But It’s too late)
They said: Each soul has its Given Date,
When it must leave its body’s core,
And meet with its Eternal Fate>
On mark the words that I do say,
Who knows? Tomorrow could be your day,
At last, it comes to Heaven or Hell
Decide which now, Do NOT delay!
Come on my brothers lets pray
Decide which now do not delay….
Oh God! Oh God! I cannot see!
My eyes are blind! Am I still me?!!
Or has my soul been led astray,
And forced to pay a Priceless fee?!
Alas to Dust we all return,
Some shall rejoice, while others burn,
If only I knew that before
The line grew short, and came my Turn!
And now, as beneath the sod
They lay me (with my record flawed),
They cry, not knowing I cry worse,
For, they go home, I face my God!
Oh mark the words that I do say,
Who knows? Tomorrow could be your day,
At last, it comes to Heaven or Hell
Decide which now, Do NOT delay!
Come on my brothers lets pray
Decide which now do not delay….
Today, upon a bus,
I saw a girl with golden hair.
and wished I was as fair.
When suddenly she rose to leave,
I saw her hobble down the aisle.
She had one leg and wore a crutch.
But as she passed, she smile.
Oh God, forgive me when I whine.
I have 2 legs, the world is mine.
With feet to take me where I'd go.
With eyes to see the sunset's glow.
With ears to hear what I'd know.
Oh God, forgive me when I whine.
I've been blessed indeed, the world is mine
I stopped to buy to buy some candy.
The lad who sold it had such charm.
I talked with him, he seemed so glad.
If I were late, it'd do no harm.
And as I left, he said to me,
"I thank you, you've been so kind.
You see," he said, "I'm blind."
Oh God, forgive me when I whine.
I have 2 eyes, the world is mine.
With feet to take me where I'd go.
With eyes to see the sunset's glow.
With ears to hear what I'd know.
Oh God, forgive me when I whine.
I've been blessed indeed, the world is mine
I saw a child with eyes of blue.
He stood and watched the others play.
He did not know what to do.
I stopped a moment and then I said,
"Why don't you join the others, dear?"
He looked ahead without a word.
And then I knew, he couldn't hear.
Oh God, forgive me when I whine.
I have 2 ears, the world is mine.
With feet to take me where I'd go.
With eyes to see the sunset's glow.
With ears to hear what I'd know.
Oh God, forgive me when I whine.
I've been blessed indeed, the world is mine.
Proteins are made of strings of amino acids that form chains known as peptides. Proteins differ by the types and order of amino acids they contain. Even though there are only 20 amino acids, they create almost endless variations in chains as long as 500 links.
site of synthesis:-
Proteins form inside animals (including humans) and plants through processes that synthesize peptides. For humans, we cannot synthesize certain "essential protein," and so we must ingest them through food. These essential proteins are made of phenylalanine, threonine, methionine, tryptophan, leucine, isoleucine, lysine, and valine amino acids.
Functions pf proteins:- Our bodies need dietary protein to accomplish many basic functions, such as:- 1- building bones. 2- moving muscles. 3- repairing tissue. 4- a catalyst in metabolism. 5- They're involved in the nervous system function. 6- bringing energy to cells.
Dietary protein, an essential nutrient, comes from meat, dairy, and certain grains and beans.
Food from plants, like corn, have incomplete protein, which means they do not contain all the necessary amino acids. Only food from animals, such as cheese and fish, provide complete protein, and don't need to be combined with other protein sources.
Examples of complete protein foods are :-
milk, cheese, yogurt, butter, poultry, pork, or any meat. Incomplete proteins include oats, wheat, pasta, lentils, nuts, rice, soy, pears, and seeds. Eating a combination of complementary protein sources, such as grains mixed with legumes, results in a diet of essential protein. This is how vegetarians and vegans maintain health without eating meat or dairy.
Dietary requirements:- vary from 40-70 gm of protein per day.
Disturbances:- 1- Too much protein might deplete calcium, 2- while too little causes a form of malnutrition called kwashiorkor. Insufficient protein weakens the heart and other muscles, eventually leading to death. 3- Incidentally, proteins are responsible for most food allergies.
