DEPRESSORS

Depressors are a type of ophthalmology instrument used to depress or push down the eyeball during an eye exam or procedure. This allows the examiner to better visualize the inside of the eye, including the retina and optic nerve. There are several types of depressors commonly used in ophthalmology:

Desmarres Lid Retractor: This instrument is used to retract the eyelids and keep them open during an exam. It is commonly used during ophthalmic surgery and is available in different sizes.

Wire Lid Speculum: Similar to the Desmarres lid retractor, this instrument is used to hold the eyelids open during an exam or procedure. It consists of a wire frame that fits around the eye and is held in place with a screw or other mechanism.

Scleral Depressor: This instrument is used to depress the sclera, or the white of the eye, in order to examine the peripheral retina. It is commonly used during a dilated fundus exam or during retinal surgery.

Chalazion Curette: This instrument is used to remove a chalazion, which is a small lump or cyst that forms on the eyelid. The curette is used to scrape and remove the contents of the chalazion.

Lacrimal Probe: This instrument is used to probe the tear ducts in order to identify and treat any blockages or obstructions.

Muscle Hook: This instrument is used to hook onto and isolate the extraocular muscles in order to perform surgery or make adjustments to their positioning.

These are just a few examples of the types of depressors used in ophthalmology. The specific instruments used will depend on the type of exam or procedure being performed. It is important that these instruments are used by trained professionals to ensure accurate and safe examinations or surgeries.
