Question

Match List I with List II
List I:
A. Otitis externa
B. Epiphora
C. Corneal ulcer
D. Ptosis
List II:
I. Excessive flow of tears
II. Drooping of eyelids
III. Membranoplasty
IV. Zepp's operation
V. Bulla osteotomy
Choose the correct answer from the options given below:

• A. A-II, B-I, C-III, D-IV
• B. A-V, B-III, C-I, D-IV
• C. A-IV, B-I, C-III, D-II
• D. A-II, B-IV, C-III, D-I

Hint:

Remember: "Zepp's lateral ear resection" is the classic surgery for chronic otitis externa (A-IV), and "ptosis" is derived from Greek, meaning "falling" or "drooping" of the eyelid (D-II).

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
Veterinary surgical pathology involves identifying clinical abnormalities of the eyes and ears and linking them to their corresponding corrective surgical interventions or definitions.

Step 2: Detailed Explanation:
Let us match the clinical conditions in List I with the correct definitions or procedures in List II:
- A. Otitis externa: Chronic inflammation of the external ear canal.
Zepp's operation (IV) (lateral ear canal resection) is a surgical technique used to treat chronic otitis externa by facilitating ventilation and drainage.
- B. Epiphora: This is defined as an overflow of tears from the eyes onto the face, caused by overproduction of tears or obstruction of the nasolacrimal duct (I).
- C. Corneal ulcer: A loss of the epithelial layer of the cornea.
Membranoplasty (III) (such as a third eyelid flap or tarsorrhaphy) is performed to cover, protect, and support the healing of deep or indolent corneal ulcers.
- D. Ptosis: This is the medical term for the drooping of the upper eyelid (II), usually caused by nerve dysfunction (oculomotor or sympathetic pathways).
- Note: Bulla osteotomy (V) is used for otitis media and is not matched here.
This results in the sequence: A \(\rightarrow\) IV, B \(\rightarrow\) I, C \(\rightarrow\) III, D \(\rightarrow\) II.

Step 3: Final Answer:
The correct matching sequence is A-IV, B-I, C-III, D-II.
