A PET tube is a small tube surgically placed in a child's eardrum to drain fluid and equalize pressure between the middle ear and atmosphere. The eye, ear, nose and throat refer to the organs of sight, hearing/equilibrium, smell, and passage to the stomach/lungs respectively. Bone conduction is the transmission of sound to the inner ear through skull bones, explaining why one's recorded voice sounds different. Otitis media refers to middle ear infections often preceded by upper respiratory infections spreading via the Eustachian tube. Emmetropia describes proper eye refractive correlation to axial length bringing light parallel to the optic nerve into focus on the retina. Exotropia is an outward turning eye occurring during

2. Pressure equalizing tube ( PE Tube) Small tube surgically placed in child’s eardrum to assist in drainage of trapped fluid and to equalize pressure between the middle ear cavity and the atmosphere.

3. Eye, ear, nose and throat (EENT) EYE THROAT Eye- The organ of sight. Ear- The externally visible cartilaginous structure of the external ear and the sense organ for hearing and equilibrium. Nose: The organ of smell and entrance to the respiratory tract; the prominent part of the face of man or other mammals. Throat: The passage to the stomach and lungs; in the front part of the neck below the chin and above the collarbone. EAR NOSE

4. Bone conduction(BC) Bone conduction is the conduction of sound to the inner ear through the bones of the skull Bone conduction is the reason why a person's voice sounds different to him/her when it is recorded and played back.

6. Otitis media(OM) Middle ear infections, also known as otitis media, are among the most common illnesses of early childhood. It is often preceded by an upper respiratory infection during which pathogens move from the pharynx to the middle ear via the Eustachian tube.

7. Emmetropia(EM) a state of proper correlation between the refractive system of the eye and the axial length of the eyeball, rays of light entering the eye parallel to the optic axis being brought to focus exactly on the retina.

8. Exotropia(XT) Exotropia,(a type of strabismus) or an outward turning eye, occurs most often when a child is focusing on distant objects. Often the exotropia will occur intermittently, particularly when the child is daydreaming, ill, or tired. Parents often notice that the child squints one eye in bright sunlight.

9. Left eye(OS)

10. Extraocular Movement(EOM) Eye movements that are controlled by muscles innervated by cranial nerves III, IV and VI.

11. Visual acuity(VA) Sharpness of vision, especially as tested with a Snellen chart. Normal visual acuity based on the Snellen chart is 20/20. Thanks!
