Lecture 1
Posterior Uveitis
Please do not prescribe emprical treatment for uveitits patient, this will mask the symptoms
كل تفكيري مع المريض ده في التشخيص الصح مش العلاج
Optic nerve may not be involoved in MS
Toxoplasmosis is a cause of retinal vasculitits
Affect retinal artery and veins
Vasculitis is a pathology of the wall
occlusion is a pathology of the lumen
ممكن يحصلوا مع بعض وممكن لا
Occulsion without inflammation may be BRVO
rare to see CRVO dt toxoplasmosis
Do not vitritis dt uninvolvement of the vitrous
Intermediate uveitis only can cause vitritis
You can say vitrous infiltration if it is not intermediate uveitis
Sarcoidosis is one of the causes of exudative vasculitits but not the only cause, TB is one of the causes
Sarcoidosis causes candle wax drippings
متحفظش أي حاجة في ال uveitis
المعلومة الرمادي اللي مش فاهمها فيها متشتغلهاش
Recurrent BRVO is Behcet disease till proved otherwise
Lecture 2
it is so hard to see normal choroid in a normal patient
Factors affecting the choroid:
Long term or short term
Long term: Myopic patient - thinning of the choroid due to overstretching of the layer to cope with the axial length
Short term:
Drinking water: increase the thickness
Drinking coffee: decrease the thickness
Smoking: Decrease the thickness
بلاش الحجات دي من 3 الي 4 ساعات قبل الفحص
We should exclude that before attributing any change in the thickness to the pathology
Difference between Choroiditis and Retinitis:
Choroiditis:
Lesions are more yellowish
Retinal vessels are uninterrupted
lesions are well defined
Retinitis:
Lesions are more whitish
Retinal vessels are interrupted
Lesions are ill defined
There is overlap sometimes:
in deep retinitis, the retinal vessels are uninterrupted
Choroiditis Lesions:
one lesion - small: Focal Choroiditis
2 lesions or more- small : Multifocal Choroiditis
1 lesion - large : Geographic
2 lesions or more - large: Disseminated (TB- AIDS)
Multifocal serbiginous Choroiditis : TB
vitrous cells is not an indication of activity and absence of vitrous cells is not an indication of inactivity
Birdshot Retinochoroidopathy usually misdiagnoesd with Harada
1 single pigmented lesion in the fundus exclude Birdshot
Birdshot is lesions of the inferior and nasal quadrant
Cream colored lesions not chalky white
Lesions are oval, elongated, fusiform , ms form
