We show that if a surgery on a knot in a product sutured manifold yields the same product sutured manifold, then this knot is a 0or 1-crossing knot. The proof uses techniques from sutured manifold theory.
OBJECTIVE To present a comprehensive review of current and historical literature on scleral lenses. METHODS A comprehensive search of several databases from each database's earliest inception to May 23, 2014 was conducted by an experienced librarian with input from the author to locate articles related to scleral lens design, fabrication, prescription, and management. RESULTS A total of 899...
Scleral fixation of intraocular lenses (IOLs) can be performed under the protection of a scleral flap. A variation of this technique uses a scleral tunnel for suture fixation to the eye. Passage of a double-armed suture through the roof of the scleral tunnel with subsequent retrieval of the suture ends through the external incision for tying facilitates scleral fixation. This modification offer...
BACKGROUND Scleral buckling is still a common procedure to repair rhematogenous retinal detachment, and acute or chronic infection of the scleral explant is rare. We report an intractable case of acute scleral explant infection by Pseudomonas aeruginosa. CASE A 36-year-old man suffered from acute scleral explant infection by P. aeruginosa forty-eight hours after scleral buckling for rhegmatog...
Background/aims: Macular translocation with scleral imbrication is a new technique for treating subfoveal choroidal neovascular membranes (CNV). This procedure shortens the sclera but may result in a minimal decrease in the internal circumference of the globe and limits the amount of foveal displacement. The authors propose a new scleral retraction suture aimed at decreasing the internal circum...
PURPOSE To obtain information about scleral thickness in different ocular regions and its associations. METHODS The histomorphometric study included 238 human globes which had been enucleated because of choroidal melanomas or due to secondary angle-closure glaucoma. Using light microscopy, anterior-posterior pupil-optic nerve sections were measured. RESULTS In the non-axially elongated grou...
Preserved human scleral graft and histoacryl-blue tissue adhesive were used in four cases of retinal detachment surgery to obtain scleral buckling effect and to protect staphylomatous or necrotic scleral areas. The use of histoacryl produced a strong and resistant adhesion between the host and the preserved scleral patch. The postoperative inflammatory reaction was mild and disappeared within o...
The relationship between scleral birefringence and biometric parameters of human eyes in vivo is investigated. Scleral birefringence near the limbus of 21 healthy human eyes was measured using polarization-sensitive optical coherence tomography. Spherical equivalent refractive error, axial eye length, and intraocular pressure (IOP) were measured in all subjects. IOP and scleral birefringence of...
