BACKGROUND In vivo reflectance confocal microscopy (RCM) is a promising non-invasive skin imaging technique that could facilitate early diagnosis of basal cell carcinoma (BCC) instead of routine punch biopsies. However, the clinical value and utility of RCM vs. a punch biopsy in diagnosing and subtyping BCC is unknown. OBJECTIVE To assess diagnostic accuracy of RCM vs. punch biopsy for diagno...

Purpose. To evaluate the efficacy of autologous tenon grafting combined with conjunctival flap as a treatment for scleromalacia or scleral thinning after pterygium excision without any additional donor graft tissue. Methods. Twenty-six cases underwent autologous advanced tenon grafting combined with sliding or rotating conjunctival flap for scleromalacia after pterygium surgery ranging from 2 y...

PURPOSE To determine the in vitro permeability of the sclera to high molecular weight compounds and the relationship between scleral permeability and molecular size. METHODS Fresh rabbit sclera was mounted in a two-chamber diffusion apparatus, and its permeability to sodium fluorescein, fluorescein isothiocyanate (FITC)-conjugated bovine serum albumin, FITC-IgG, and FITC dextrans ranging in m...

The scleral spur and scleral roll together form a fibrous hoop which may be detached from adjacent structures as a unit. Tensile tests of the spur-roll resemble reported data on sclera. It is proposed that the circular structure of the spur-roll prevents action of the meridional portion of the ciliary muscle on the trabecular meshwork from collapsing the canal of Schlemm.

Posterior scleral tuberculoma formation is an extremely rare condition. The few reports on scleral involvement in tuberculosis refer to cases of anterior scleritis. In the present manuscript we describe a patient who had rheumatoid arthritis and developed a large posterior scleral tuberculoma. The lesion provoked retinal detachment and visual loss and was diagnosed only after enucleation due to...

Scleral buckling is a highly successful technique for the repair of rhegmatogenous retinal detachment that requires intra-operative examination of the retina and treatment of retinal breaks via indirect ophthalmoscopy. Data suggest that scleral buckling likely results in improved outcomes for many patients but is declining in popularity, perhaps because of significant advances in vitrectomy ins...

Scleral contact lens technology had been applied for several years as part of the treatment of ocular surface diseases, as well as for compensation of corneal surface irregularities. In recent years, new scleral lens designs were developed to compensate for current refractive errors. Becoming more widely used, it is crucial to question the long-term effects of their presence on ocular health. O...

Solutions to the Boussinesq problem for the circular punch without axial symmetry can be obtained from corresponding axisymmetric solutions by parametric differentiation. The method is applied to the problem of the tilted fiat punch, originally solved by Green, and to the indentation of a cylindrical surface by a flat circular punch.

This study describes a new tibial cement punch pressurizer to enhance cement penetration into the metaphyseal cancellous bone of the tibial plateau. Thirty knees of 15 patients undergoing simultaneous bilateral total knee arthroplasty (TKA) were randomly selected to receive the tibial cement punch pressurizer on one side, with the opposite side serving as control. Using computerized and radiogr...

The bidirectional laser Doppler technique and monochromatic photography were used to measure the absolute blood flow rate in the major temporal retinal arteries in seven patients following unilateral scleral buckling and encircling procedures, and in two patients before and after removal of scleral buckling elements. In the seven patients who had undergone uncomplicated scleral buckling procedu...
