POSTERIOR UVEITIS | retinitis v/s choroiditis

POSTERIOR UVEITIS | retinitis v/s choroiditis
the video discusses in detail about retinitis and its differential diagnosis. It also discusses how to differentiate retinitis lesion from choroiditis.
The inflammation of retina and choroid is called posterior uveitis Posterior Uveitis can manifest as retinitis, choroiditis, vasculitis, neuroretinitis, retinochoroiditis, chorioretinitis.
retinitis can be focal or diffuse retinitis. The causes of focal retinitis include toxoplasma, toxocariasis, onchocerciasis and masquerade syndromes.
Multifocal retinitis is caused by syphilis, sarcoid, viral retinitis ( ARN, PORN and CMV retinitis, DUSN .
Retinitis can be differentiated from choroiditis based on the morphology. Retinitis lesions are bright yellow in color obscuring the vessels passing through them. Choroiditis lesions are dull yellow or orange in color and elevated in nature with vessels passing on top pf the lesions visble clearly. This happens as the choroidal lesions are deeper in location .

Hello, maam. Awesome lecture. I am your longterm viewer. Bookish terms which we couldnt visualise, u explained brilliantly.
Maam, can you please explain the difference between perivascular sheathing of vessels and sclerosed vessels and how to distinguish them clinically.
Thank u maam

[@InsightOphthalmology]

Sclerosis of vessel is thickening of vessel wall secondary to atherosclerosis or chronic hypertension, leads to narrowing of vessel lumen and ischemia. Seen in hypertension and associated with AV nicking and other signs and identified as silver and copper wiring. It's more demarcated
Perivascular sheathing is exudation around the blood vessels. It is vasculitis. Can be around vein or artery and will show other signs of inflammation. Seen in MS, EALES disease or sarcoid ( candle wax drippings).
So here the whitish things are actually infilterates around the vessel and these are fuzzy, not as demarcated and regular in sclerosis ; which is thickening of vessel wall itself.
Thank you for supporting SK ❤

Good Day Ma'am. U're a wonderful teacher. Thank u so much for dis class, I appreciate. Please Ma'am am I to understand dat Retinal necrosis is another name for Retinitis lesions? Also, Ma'am can u please enlighten us on retinal vasculitis?

[@InsightOphthalmology]

Thank you for your comment!
No retinitis and necrosis are different. In retinitis the cells are present but and there is edema of the retina as the suffix -itis suggest.
But in necrosis the cells actually start destroying the retina ..it's more severe inflammation than just retinitis

[@joe8072]

OK Ma'am. But which features would show dat there's necrosis in the Retinitis? How would it appear like?

[@diana95187]

Hello! I have a question,please:what is the difference between endophtalmitis and panuveitis?

[@InsightOphthalmology]

They are essentially the same...you can think of endoph as infectious panuvietis
