Thanks

Thanks Glad to hear your opinion.

Ask the pt to open the other eye and look straight ahead.

@@adelabdelshafik thanx alot prof ,may allah bless you

You are right. Another important sign : the central part of iris around the pupil is more anterior than that part near to Ciliary body, indicating concave iris insertion to the CB

@@adelabdelshafik Thank you for your guidance!

Welcome

@@adelabdelshafik My one doubt is if Goldmn mirror is used for Trabeculoplasty then where to target laser beam because image is inverted

@@piyachoudhari.1111 When mirror is at 12 o clock you are seeing 6 oclock of the angle. you apply laser to the mirror so it will reach 6 oclock area. laser is applied to the TM as seen in the mirror. Gradually you rotate the goniolens and keep apply laser to the mirror to reach the oposite part of the angle

Thanks, Glade to hear your opinion.

I agree with boold on iris and angle recession.

@@adelabdelshafik Thank You for your guidance! Your videos are really nice and helpful ! I wish I had teachers like you in my college ! What's your superspecialty? Are you a glaucoma specialist ? Honestly I always found Glaucoma diagnosis and starting the treatment little challenging especially in early cases I really used to get confused in some cases whether to start the treatment or not in some patients and I had to take me the opinion of senior consultants and hence I decided to revise all the system once again later it's optics and squint these three systems I find little challenging to understand and grasp especially the optical principles behind certain concepts in squint and Optics ! Thank you for your replies ! So kind of you !

@@piyachoudhari.1111 My superficiality is glaucoma and cornea.

@@adelabdelshafik Thank you for the information !

@@piyachoudhari.1111welcome

Your are right.

thanks

OK

no way to be sure of diagnosis depending on one investigation only. consult your doctor. He needs history, examination, and OCT and field of vision to reach a diagnosis.

@@adelabdelshafik thank you so much sir, recently I have visited an eye hospital for eye checkup regarding the floaters. I am a myopic patient having -2.00 right and -1.75 left. I was told after oct test that you have early glaucoma, I was shocked to hear that since I am just 23 and never had any family history of glaucoma. they given m'e eye pressure medicine too. I am not using it currently I want it to be confirmed by another doc too. That's why I asked you that if you could see my prescription interpret my oct. It would be helpful sir.

@@Learner-lq3vu no way to be sure of a diagnosis using OCT only. 25-33% of normal persons or those with small myopia if less than 4 D may show changes similar to those of glaucoma. so if you want to be sure you can consult another dr whole will have all data needed.

@@adelabdelshafik so doc there might be a chance that even if i have myopia of -2.00 and -1.75. There might be a chance that my eye oct result can show as glaucoma despite being normal?

@@Learner-lq3vuYes

we you please check that one : 001 Optics course (New) : Principles of refraction - Snell's law ua-cam.com/video/9mO0geothHw/v-deo.html

May you watch these videos : the English version you asked for. 1. ua-cam.com/video/9mO0geothHw/v-deo.html and 2.studio.ua-cam.com/users/videov1M0jGp2HSM/edit

I am out of Egypt now , when I return will record new video in English.

😊 thank you Sir

My website is closed for couple of years now. Sorry that some of my videos still showing that abundant website.

You can try google search " buy cross cylinder" and find a source accessible to you.

شكرا ربنا يكرمك

thanks

Yes. You are right.

The point to keep in mind is changes in OCT may occur in 1/3-1/4 of normal persons. So to diagnose glaucoma you need to have multiple different areas starting from family history, suggestive symptoms, abnormal angle configuration, suspicious disc, suspicious field changes, lower systemic BV, high myopia...... etc the more the abnormal factors the more the diagnosis is correct. so as you said, if not sure just keep pt under observation.

@@adelabdelshafik Thankyou...

Both are useful. Common practice is to start with trab. and if needed needling of bleb(several times) and if needed another trab or Glaucoma valve. Glaucoma valves are not typically applied as primary procedure except when trab is not suitable as in cases when risk of fibrosis is high. e.g. neovascular glaucoma. Both trab and Ahmed valve have possible complications and need to follow up closely and interfere whenever needed. Both are liable to failure bec of fibrosis. Ahmed valve fibrosis is late compared to trab.

welcome

the cortex part of the crystalline lens is a minscus shape lens with power of -3D for anterior half and -3D for the post half. The nucleus of the crystalline lens is a biconvex lens with power of +24D. so the total power of the crystalline lens is (24-3-3=18 D).

regarding your second question : think of -3 D as -3 degrees temperature. when the temperature is colder it will be -4 degrees , same for the minus power of the cortex is increased ,it will be more e.g. -4D.

thanks for your opinion

Yes you are right. Actually it was +5.00 then adding -2 = +3.00. I do not know how it was missed up. Thanks for your remark.

I will check my presentation, and upload in near future.

Thanks
