= 1 COCP
= 2 COCP (throught each week of the cycle)

Week 1: + EMERGENCY CONTRACEPTION
Week 2: No need for EC
Week 3: Finish pack of pills and omit the pill free interval
(due to hormonal protection being at a minimal level in week 1 so no pill could cause a chance of ovulation)
How does the Cu-IUD work?
Decreases sperm motility and survival (creates a hostile environment for sperm)
What is the relationship between cancers and the COCP?
Protective
- ovarian
- endometrial
Increased risk
- breast
- cervical
If a patient starts the following contraceptions halfway through their cycle when do they no longer need to use barrier methods?
- IUD
- POP
- COCP, injection, implant, IUS
IUD - immediately
POP - 2 days
COCP, injection, implant and IUS - 7 days
If POP is taken within how many days of the beginning of the cycle do they not need protection?
Up to and including day 5
After how long post birth do women not need protection?
21 days
POP and IUD/IUS can be started/inserted any time post birth. How does this change for COCP?
Can only be used after 21 days!!
Completely contradicted if breastfeeding <6weeks post-partum
Can be used in >6weeks and <6 months
Sytes and chalazion are both lumps of the eyelid. How can you tell the difference?
Styes are painful - staphylococcal infection of lash follicule
Unlike chalazion
How do you manage styes and chalazions and belpharitis?
Lid hygiene - warm compresses x2 day
Fluoxicillin if stye has cellulitis
Name 4 symptoms of optic neuritis
Red desaturation
Pain on eye movements
Decrease in visual acuity
RAPD - relative afferent pupil defect
How do you manage conjunctivitis?
Warm compress x2 day
Lid hygiene
HAND hygiene - to stop spread
If bacterial suspected - topical chloramphenicol drops
Cool compresses in viral
What clinical sign may you see outwith the eye in viral conjunctivits
Pre-auriclar lymphadenopathy
“Stormy-sunset” appearance on fundoscopy?
What else will they present with?
Central retinal vein occlusion
Sudden visual loss
Painless
What are you looking for on funduscopy?
- 3 C’s
- Peripheral retina
- Macula
C’s
1 - cup
2 - colour
3 - contour
DD list for blurred optic nerve disc
What clinical presentation can this cause?
Papillits - inflammation of optic nerve head - optic neuritis (seen in MS)
CRVO
Malignant HTN
Papilloedema
Increase in blind spot
What is the definition of papilloedema?
BILATERAL blurred disc margins in CONTEXT of raised ICP
Only if these conditions are met
Pale disc = bright/dark disc?
Bright disc = pale disc
What does - silver wiring - AV nipping - dot blots - blurred optic disc margain suggest?

Scleritis = deep boring pain as sclera is where intraocular muscles insert
- need oral steroids and immunosuppresion
Episcleritis - benign but can be more red
- need just NSAIDS
What is the management of acute closed angle glucoma?
What is the management of open angled?
Closed (due to fault in aqueous humor being able to get out through iris)
- IV acetazolamide
- pilocarpine = constrict pupil and pull out of closed angle
- lay patient flat
- BILATERAL peripheral laser iridotomy
Open (due to fault in trabecular network reabsorbing aqueous humour)
- latanoprost - prostagladin analgoue - decrease IOP - increase patency of trabecular network
- B-blockers - reduce aqueous production
