Ectopia lentis in Marfans and Homocystinuria

Mnemonic submitted by Alan (Thanks again) to which I have added some modification:

Ectopia lentis (Dislocation of lens) is seen in Marfans syndrome & Homocystinuria , but in one the dislocation is up (and outward) while in the other it goes down (and inward).

Remember that " urine goes down and into closet "

So lens get displaced down and inward in Homocysteinuria ,
And lens get displaced upand outward in Marfans syndrome (Opposite of above).


Now, I thought that I add a picture mnemonic to spice up things because you don't know when these will come handy.
Imagine a MAN (looking up and out to the sky) above a HOrse ( looks down and into the track) (MArfaN - up n out;  HOmocustinuria - down n in)

Classification of Retinal Detachment

Thanks to Keshav Aacharya for submitting this mnemonic.
Remember RET to classify RETinal detachment:
R - Rhegmatogenous
E - Exudative
T - Tractional

Retinal detachment

• Causes of Retinal Detachment 

Remember the retina detaches from where it SITS :
Secondary to some intra-ocular problem such as melanoma
Idiopathic
Traumatic
Surgery for cataract

• Symptoms of Retinal Detachment 

Remember 4 Fs:
Falling acuity
Floaters
Flashes (migraine)
Field loss (dark cloud covers a field of vision)

Innervation of Extra Occular muscles

Remember LR6SO4 :

Lateral Rectus is supplied by 6th cranial nerve,

Superior Oblique by 4th

and the rest of extraoccular muscles by occulomotor. 

Stye and Chalazion

STYE is Hordeolum externum (STAY OUT) ; Moll's gland / Zeis gland affected

Chalazion is Hordeolum INternum - Chronic Inflammatory granuloma of MEiBOMian glands (Remember : See (C)  me in Bombay)

Pupil

Argyll-Robertson Pupil : Remember A-R-P, P-R-A : Accomodation Reflex Present, Pupilary Reflex Absent. Pupillary reflex absent due to damage at Pretectal area. Also called the "Prostitute's pupil" (Syphilitic pupil)

What is HIPpus: It is alternate RYTHMic contractions and dialatation of the pupil. (Remember, the pupil plays HIP HOP to RYTHM)

Signs in Thyroid opthalmopathy

Kocher's sign - Starring look (Imagine a football coach starring at his player - Starring Kocher!)
STeLLwag's sign - Infrequent blinking (STiLL lids)
DaRLymple sign - LiD Retraction
Joffroy's sign - Absent Wrinkles (Remeber JAWs)  or alternatively decreased Forhead (F for joFFroy's) wrinkles on upgaze. 

Moebius sign - Weakness of convergence (M|W) or MCC - Mobieus Can't Converge

Von Graefe's - Lid Lag (Remember that some people think that ViaGra is used to improve the Love Life)

Trachoma

Herbert's pit are found in Trachoma. Classification is McCallan's Classification
Remember herberTs piTs TraChoMa McCallans
                                 T   T    C  M  M C

Corneal scars

Denseness of corneal scars increases in the order Nebula < Macula < Leukoma (i.e. L,M,N in reverse order)
