Given:

- Words: Cataract, Cellulitis, Glaucoma, Hypermetropia, Trachoma.
- Four are alike in some manner, and one is different.
- We need to select the odd one.

Formula Used:

1. Analyze the medical condition associated with each word.
2. Identify the category or similarity among four words.

Solution:

1. Analyze each word:

- Glaucoma: An eye disease that damages the optic nerve and can cause blindness.
- Hypermetropia: A refractive error in the eye, commonly known as farsightedness.
- Trachoma: A bacterial eye infection that can lead to blindness if untreated.

2. Identify the category:
- Cataract, Glaucoma, Hypermetropia, and Trachoma are all eye-related conditions.
- Cellulitis is not related to the eye; it affects the skin.

3. Determine the odd one:
- Since Cellulitis is unrelated to eye conditions, it is the odd one out.
