Ignipuncture is an obsolete procedure that involves cauterization of the retina with a very hot, pointed instrument. [22] A scleral buckle is used in the repair of a retinal detachment to indent or "buckle" the sclera inward, usually by sewing a piece of preserved sclera or silicone rubber to its surface. [23]
Sclerotomy is a medical intervention that involves surgical cutting in the white area of the eye, known as the sclera. [1] The goal of this intervention is usually done to correct defects in sclera that resulted as a complication of glaucoma of other ocular diseases. [2] Sclerotomy can be divided into anterior sclerotomy and posterior ...
The procedure begins with a 360° periotomy followed by a stab incision in the sclera. [10] [11] The incision is then expanded around the limbus circumferentially and the orbital contents are removed using an evisceration spoon. The optic disc is then cauterized and the scleral shell is cleaned. [10]
Scleral reinforcement surgery is not presently popular in the United States, and there has been a scarcity of published clinical studies. Donor sclera material is also difficult to acquire and store, and artificial materials are still being tested. This procedure is much more popular in other countries, such as the former Soviet Union and Japan ...
The scleral edge of the trepanation opening is heat-cauterized. [8] Additional deep scleral dissection can also be performed in the scleral bed with trabeculectomy, first introduced by T. Dada et al.; [9] deep scleral excision is performed in non-penetrating filtering surgeries but not traditionally in trabeculectomy. The space created from the ...
A scleral buckle is one of several ophthalmologic procedures that can be used to repair a retinal detachment. Retinal detachments are usually caused by retinal tears, and a scleral buckle can be used to close the retinal break, both for acute and chronic retinal detachments. [citation needed] Scleral buckles come in many shapes and sizes.
The sclera's blood vessels are mainly on the surface. Along with the vessels of the conjunctiva (which is a thin layer covering the sclera), those in the episclera render the inflamed eye bright red. [6] In many vertebrates, the sclera is reinforced with plates of cartilage or bone, together forming a circular structure called the sclerotic ring.
