Mnemonics: Conjunctiva
Parts of Conjunctiva
What needs to be memorized: The three anatomical divisions of the conjunctiva - Palpebral (lining eyelids), Bulbar (covering eyeball), and Forniceal (the fold between them)
Mnemonic: "Papa's Biryani is my Favourite"
🔗 The Breakdown:
- Papa's → Palpebral conjunctiva (lines the eyelids)
- Biryani → Bulbar conjunctiva (covers the eyeball)
- Favourite → Forniceal conjunctiva (the fornices/folds)
Follicles vs Papillae - Follicle Characteristics
What needs to be memorized: Key distinguishing features of conjunctival follicles - Avascular, Pale/yellowish appearance, Viral or Chlamydial cause, predominantly in Fornices
Mnemonic: "Arre, Pale Viral Fellow (in fornix)"
🔗 The Breakdown:
- Arre → Avascular (no blood vessels inside)
- Pale → Pale or yellowish appearance
- Viral → Viral or Chlamydial etiology
- Fellow → Fornices (predominantly found here)
Follicles vs Papillae - Papillae Characteristics
What needs to be memorized: Key distinguishing features of conjunctival papillae - Vascular (central vessel), Red appearance, Allergic or Bacterial cause, predominantly on Tarsal conjunctiva
Mnemonic: "Very Red Allergic on Tarsus"
🔗 The Breakdown:
- Very → Vascular (central blood vessel visible)
- Red → Red appearance
- Allergic → Allergic or Bacterial etiology
- Tarsus → Tarsal conjunctiva (predominantly found here)
Trachoma Stages (MacCallan Classification)
What needs to be memorized: The four progressive stages of trachoma - Stage I (Follicles appear), Stage II (Intense inflammation), Stage III (Scarring begins), Stage IV (Trichiasis develops)
Mnemonic: "FIST" - Make a fist to remember the progression!
🔗 The Breakdown:
- F → Follicles appear (Stage I - Trachomatous Follicular/TF)
- I → Intense inflammation (Stage II - Trachomatous Intense/TI)
- S → Scarring develops (Stage III - Trachomatous Scarring/TS)
- T → Trichiasis occurs (Stage IV - Trachomatous Trichiasis/TT)
Causes of Follicular Conjunctivitis
What needs to be memorized: The three main causes of follicular conjunctivitis - Chlamydial infections (Trachoma and Inclusion conjunctivitis), Adenoviral infections, and Molluscum contagiosum
Mnemonic: "CAM makes Follicles"
🔗 The Breakdown:
- CAM → Chlamydial infections (Trachoma, Inclusion conjunctivitis)
- CAM → Adenoviral infections (PCF, EKC)
- CAM → Molluscum contagiosum
Additional less common causes: Newcastle disease, Moraxella, Toxic conjunctivitis
Membranous Conjunctivitis - True Membrane
What needs to be memorized: Causes of TRUE membrane (bleeds on removal) - Diphtheria, Ligneous conjunctivitis, Severe chemical injury, Beta-hemolytic Streptococcus
Mnemonic: "DiL Se Bleeds" (like the Bollywood movie Dil Se - from the heart it bleeds!)
🔗 The Breakdown:
- DiL Se → Diphtheria
- DiL Se → Ligneous conjunctivitis
- DiL Se → Severe chemical injury / Streptococcus (beta-hemolytic)
Remember: TRUE membrane bleeds when you try to remove it!
Membranous Conjunctivitis - Pseudomembrane
What needs to be memorized: Causes of PSEUDOMEMBRANE (doesn't bleed on removal) - Adenovirus (EKC), Gonococcus, Streptococcus pneumoniae
Mnemonic: "AGS - No Bleed"
🔗 The Breakdown:
- AGS → Adenovirus (Epidemic Keratoconjunctivitis)
- AGS → Gonococcus
- AGS → Streptococcus pneumoniae
Remember: PSEUDO membrane comes off easily without bleeding!
Ophthalmia Neonatorum - Timing of Organisms
What needs to be memorized: Time of onset for different organisms causing neonatal conjunctivitis - Gonococcus appears at 2-5 days, Chlamydia appears at 5-14 days
Mnemonic: "GO fast (2-5 days), CHAM slow (5-14 days)"
🔗 The Breakdown:
- GO fast → GOnococcus presents early at 2-5 days (hyperacute, purulent)
- CHAM slow → CHAMydia presents late at 5-14 days (inclusion conjunctivitis)
Additional: Chemical conjunctivitis (silver nitrate) occurs within 6-12 hours if used
Vernal Keratoconjunctivitis (VKC) - Classic Triad
What needs to be memorized: The three pathognomonic features of VKC - Giant papillae (cobblestone appearance), Trantas dots (at limbus), Shield ulcer (on cornea)
Mnemonic: "Get That Shield!" - VKC ka classic triad
🔗 The Breakdown:
- Get → Giant papillae (cobblestone appearance on upper tarsal conjunctiva)
- That → Trantas dots (white dots at limbus in limbal form)
- Shield → Shield ulcer (on superior cornea)
Bonus tip: VKC commonly affects young BOYS in SPRING/SUMMER season with intense ITCHING!
