A non-invasive imaging technique that uses light waves to create cross-sectional images of tissues, particularly the retina.

Fluorescein Angiography

A medical imaging technique that uses a special dye (fluorescein) and a camera to visualize the blood vessels in the back of the eye.

Tuning fork test

Simple, bedside assessments of hearing that help differentiate between conductive and sensorineural hearing loss.

Otoscopy

A medical procedure that involves examining the ear canal and eardrum using an otoscope.

Vestibular System

Part of the inner ear involved in balance and spatial orientation.

Eustachian Tube

Binaural Hearing

The ability to hear with both ears, allowing for localization of sound.

Audiogram

A graphical representation of an individual's hearing ability across different frequencies.

Saccule

A structure in the inner ear that helps detect gravity and linear acceleration.

Utricle

A part of the vestibular system that aids in sensing head position and linear movements.

Otosclerosis

A condition where abnormal bone growth in the middle ear disrupts hearing.

Presbyopia

An age-related condition affecting the eye's ability to focus on near objects.

Astigmatism

A common vision condition caused by an irregular shape of the cornea, leading to blurred vision.
