- Amblyopia [ LAZY EYE ] is one of the most common causes of vision loss in childhood. Conventionally, amblyopia has been considered as a unilateral visual diminution and hence, most definitions fail to describe the visual acuity in defining bilateral amblyopia.
Amblyopia is defined as a decrease of visual acuity in one eye when caused by abnormal binocular interaction or occurring in one or both eyes as a result of pattern vision deprivation during visual immaturity, for which no cause can be detected during the physical examination of the eye(s) and which in appropriate cases is reversible by therapeutic measures.
Amblyopia can be c;lassified as strabismic amblyopia, refractive amblyopia ( anisometropic amblyopia, isoametropic amblyopia, meridional amblyopia), vision deprivation amblyopia, organic amblyopia, and idiopathic and reverse amblyopia. the video explains each type in detail .
why amblypoia is more common in esodeviation than in exodeviation and the critical period of development is also explained in the video.

Thank you for this video, I was diagnosed with amblyopia at the age of 7 years 10 months and had severe vision loss in my left eye by then. It was improved by wearing a patch over my right eye for several hours a day and with glasses. I'm now 64 yo.
thank you for sharing 😊😊
Did you wear the patch as an adult?
No need for patching past 17/18 it won’t make a diff. Recent research that has come out has shown that the same amount of vision recovery can be achieved with 1 hour of patching a day ….. sorry you had to do several😂😂😂
I didnt understand how can fovea compare with nasal retina and lose ..isnt fovea the brightest spot with more amts of cones? So foveal omage of esotropic eye should be more bright than that formed on temporal retina@@InsightOphthalmology
Informative video👍
GREAT MAM .....YOU TEACH IT WELL
nice explanation. thank you very much
I was diagnosed at 2 years old, after my mother saw me walk into things and fall down stairs. Wore the patch for a few years, then my vision improved. My amblyopia returned in my 20’s. I now feel like I’m 2 yo again, walking into things, and falling down stairs, and for some reason my brain doesn’t get the information from my eye, I have a hard time finding things, because my brain doesn’t get the information.
Hi dear!
My younger sis also has it.
What's ur diopters of both eye?
@@AK-zw3yz I haven’t had my eyes checked for 5 years because of Covid, and money. I am supposed to go every year. The last time my eyes were checked I have 4 diopter almost 5 diopter vision, but it’s worse now, so I need a new prescription. My Amblyopic eye is worse, also have astigmatism and myopia.
Thx for this clear explanation...mam
Ma'am can you please tell me, why you say temporal hemifield (nasal retina) is stronger than the nasal hemifield (temporal retina)
My vision in my lazy eye was not blurred. Maybe a little out of focus and had gray, motled dots. However, I could not read with that eye. Letters looked scrambled and small. I had cataract surgery, and know I can read large font. Everything looked crisp, until I had a reaction to ketolorac eye drops and my cornea swelled. Objects still look good after using Muro drops.
Thank you
thank you
Such beautiful explanations ❤️❤️
Thank you 😊
Excellent thank you.
You are welcome!
didn't understand the role of VEP in Morfological retinal damage. as I know vep gives visual cortex abnormalities information. how I know the Morfological retinal damage?
VEPs are used primarily to measure the functional integrity of the visual pathways from retina via the optic nerves to the visual cortex of the brain.
waiting for morden treatment of Amblyopia vedio.
My sister right eye -1.5 and left one is -6. Is it amblyopia?
CAN YOU EXPLAIN MORE ABOUT MERIDIONAL AMBLYOPIA...??
Is every person with VA less than 6/9 is having amblyopia in that eye ??
Fabulous video. Patient does not improve vision with pin hole then it is said amblyopia?
No, if the patient doesnot improve with pinhole.. It means that the cause of decreased vision is not refractive... However there could be other causes causing the decreased vision...
It is amblyopia if we do not find any obvious ophthalmic disease attributing to vision loss
My question is about anisometropic amblyopia. We know the difference between 2.5D or more is defined anisometropic amblyopia. If a patient having one eye -2 and another -5 . If he can read upto 6/6 line then that is also anisometropic amblyopia? Plz explain
No then it's only anisometropia, not amblyopia
Mam which amblyopia is likely to get treated in teenagers ??
Mam one doubt..u said in the start that amblyopia is loss of vision with out any physical cause in the eye..but then u also told that there are causes like cataract n all which cause this ..?
Amblyopia is basically a diagnosis of exclusion. If there is any cause of poor visual acuity, one needs to correct that cause and after the correction, if vision is still poor then one can consider Amblyopia. Cataract is a cause of poor vision and uncorrected poor vision during developmental years due to any cause is causally related to Amblyopia.
So as long as cataract is present , we cannot call it Amblyopia ( although cataract can cause Amblyopia)
After removal of cataract, if the patient's vision doesn't improve, we can label it as vision deprivation amblyopia
Ohh okkk now I understood thankyou
Mam in 4:11 u said visual acuity Is decreased and not improving..So here u r talking of uncorrected visual acuity or BCVN.-best corrected vision
Plzz reply
BCVA
