Depressors, Surgical, Sclera
Definition : Surgical depressors designed to displace by compression (e.g., roll) the white outer coat of the eyeball (i.e., the sclera), facilitating the examination of the surrounding tissue in the eye. These instruments a handheld, manual, slender instrument with a loop or other appropriate tip at the working end and a handle or a thimble-like (either closed or open) attachment at the proximal end. Scleral examination depressors permit surgeons to view the peripheral fundus while looking tangential to the retinal surface and to see the peripheral retina using an ophthalmoscope; they are used to visualize retinal tears, breaks, and/or elevations before or during surgery. Dedicated pediatric scleral depressors permit the examination of newborn eyes for retinopathy of prematurity (ROP).
