hey everyone this lesson is on medical terminology for the ophthalmologic system so the system involving the eyes so we're going to talk about different prefixes and suffixes in this lesson to describe the i in eye conditions so we're going to first talk about what the word optimal logic means so we actually break down the word into pieces so opthalm or opthalmo the prefix ophthalmo means i so it refers to the eye and the term allage comes from ology meaning study of and then the suffix ik means pertaining to so when we put this all together ophthalmologic means pertaining to the study of the eyes so that is what optimal logic means so we know that the prefix opthalm or ophthalmo means i so you can think of ophthalmologist but we can also see that the prefix opt also means i and you can think of words like optic or optometrist and then the suffix opia so you can see here there's all these parts here o-p-o-p-o-p so they all have something to do with the eye but opia if you've seen my previous lessons ia usually means condition so opia means condition of the eye and then some prefixes that are more specific for the ophthalmologic system that might not be necessarily the case with regards to other medical terms include the prefix my which means short-sighted or it refers to short-sighted so you might have seen this prefix before in other lessons my or my o usually means muscle but with regards to the ophthalmologic system we see that my usually refers to short-sightedness hyper so the prefix hyper hyper usually means above or high but with regards to the ophthalmologic system it really means far sighted and then the prefix presby presby refers to focusing of the lens so we're going to look at some of these medical terms and some practice problems later to see how these fit so with regards to hyper hyperopia is the condition of being farsighted presbyopia means or refers to a condition involving an issue with the lens so you can see conditions that we use the suffix opia with some of these prefixes so let's talk about the i in general so we're going to first talk about the prefix conjunctive which refers to the conjunctiva so the conjunctive is the layer surrounding the eye so we can think of words like conjunctivitis so inflammation of the conjunctiva the prefix sclera refers to the sclera so the sclera are the whites of the eyes and you can think of words like scleritis so an inflammation of the sclera another one is ire or ira so the iris is the colored muscle that controls the contraction allowing more or less light through the pupil so you can think of iritis as well so that's another term you could use an inflammation of the iris blepharite refers to the eyelid and as i will continue to use the same example blepharitis is an inflammation of the eyelid so this can be a common cause of reddened eyelids in older patients some other terms or other prefixes that can be used to describe the eye and eye related structures include lacrim so lacrim the prefix lacrima refers to tears and you can think of lacrimal doctor tear duct lacrimation means crying or there's tears so your production of tears and then we can see here here's another suffix that can be used to describe conditions but in this case it's a condition of the pupils or chorea so the suffix chorea so ia again means abnormal condition or a condition and in this case korea means condition of the pupils so let's take a look deeper into the eye with regards to medical terms to describe the eye so the first one is corn or cornea so corn the prefix refers to the cornea so the outer layer of the eye ache the prefix ache refers to the aqueous humor so the aqueous humor lies in this area here the anterior chamber the prefix fake means lens so it refers to the lens of the eye the next one is vitri or vitrio referring to the victory's humor so the vitreous humor is the fluid that is inside the main area of the eye and then the prefix retin or retinol refers to the retina the back layer of the eye that receives light and transmits that into a pattern that's recognized as vision by the brain so you can think of words like retinopathy so a disease of the retina so again corn refers to cornea so you can think of corneal abrasion that is a scraping or an abrasion of the cornea the prefix ache referring to aqueous humor and really or aqua you can think of words like water fake refers to the lens of the eye vich or vitrio refers to the victory's humor and then retin or retinol referring to the retina so you can think of again a word like retinal detachment as a condition so now that we've learned some medical terms to describe the anatomy of the eye and some eye conditions let's practice with those medical terms we just learned so the first practice problem we're going to look at is the term pseudophakia so try to break this word down and see what it means so the first part we're going to do is we're going to break it down into the prefix so the prefix pseudo you might have heard of this in commonly used language pseudo refers to something that is false it's not true so it's usually something that appears to be true or appears to be real but it's not and then the other part of this word is fake and we learned that fake or fakeo refers to the lens of the eye and then we know that the suffix ia refers to condition or an abnormal condition so when we actually put this all together pseudophakia is a condition of having a fake or false lens and you might be wondering what do i mean by that it's actually when someone has cataract surgery so the lens is actually removed and a artificial lens is actually put inside the eye and we call those patients pseudophakic so they have the lens inside their eye and when we look we see that they don't have their actual natural lens they have a artificial lens so that is pseudo fakie or that patient would be referred to as pseudophakic the next medical term we're going to practice with is the term blepharitis so again we break it down into the prefix so blepharo you remember what that means blephara means or refers to the eyelid and then itis the suffixitis means inflammation so when we actually put this together blepharitis is an inflammation of the eyelids and again i told you before that this is a common occurrence in older patients blepharitis and then the third medical term we're going to look at to break down to practice is the term vitrectomy or vitriectomy so vitrectomy if we break it down vit or vitra refers to the vitreous or vitreous humor and then the suffix ectomy refers to surgical removal or extraction so vitrectomy is the surgical extraction or surgical removal of the vitreous humor from the eye and some surgeries may do this for certain reasons so again pseudophakia so we look at this word again pseudo meaning false and then fake or fakie referring to a condition of the lens and again this is something we call patients who have had cataract surgery they're pseudophakic or they have pseudofacia blepharitis is blephara meaning eyelid and itis meaning inflammation so it's an inflammation of the eyelids and then which or vitrectomy vitra means vitreous humor and ectomy means surgical removal or extraction so vitrectomy is a surgical extraction or removal of the vitreous humor so there's a quick lesson on
