What is a lid speculum?

What are speculums used for?

What are the 3 surgical procedures in eye removal?

In an evisceration, the implant is wrapped by the sclera with the extraocular muscles still attached.

Clinical measurements can be used to assess for eyelid asymmetry and retraction. The distance from upper eyelid margin to corneal light reflex (margin reflex distance, MRD1) can be used to assess for elevated upper eyelid position. MRD1 is normally 4-5mm and may be increased in patients with upper eyelid retraction.

What are lower lid retractors?

Lower Lid Retractors. 1 The lower lid retractors are fascial extensions (the capsulopalpebral fascia) off the inferior rectus muscle, which inserts into the lower tarsal plate, an analog of the levator in the lower lid.
