PURPOSE Previous work has suggested a major role of scleral biomechanics in the pathogenesis of glaucoma. Since fiber orientation in connective tissues is a key determinant of tissue biomechanics, experimental characterization of scleral fiber orientation is needed to fully understand scleral biomechanics. This is a report of baseline experimental measurements of fiber orientation in whole norm...

INTRODUCTION Primary ectatic corneal diseases usually require rigid gas-permeable (RGP) corneal contact lens wear for visual rehabilitation. As the disease progresses, it becomes increasingly difficult to fit these lenses. RGP scleral contact lenses now provide another treatment option before resorting to surgery. CLINICAL PICTURE Two patients with pellucid marginal degeneration and one with ...

A deep anterior chamber of the globe is a clinical sign of posterior scleral rupture, an ophthalmologic emergency. On axial CT, the depth of the anterior chambers of ruptured globes was greater than the depth of the anterior chambers of normal globes. The discrepancy between the depth of the two anterior chambers in any patient can also suggest posterior scleral rupture.

introduction: there are different methods to repair retinal detachment. in this trial the retinopexy in repairmen of retinal regmatogenesis rd is compared with other methods in qazvin teaching hospitals during 1993-2003. methods: this out come study was conducted on 47 patients with s/b and retinal break cryopexy (group i) , 30 patients undergoing s/b with barrier laser photocoagulation around ...

purpose : to assess the rate of microbial contamination of the fornix and suture needle during strabismus surgery methods : in a prospective study in khatam-al-anbia eye hospital, fornix samples and suture needles were cultured in 28 eyes of 28 patients. fornix sampling was performed before and after preparation of the eyes and the needles and remained string were transferred to culture media d...

Soft tissue often displays marked age-associated stiffening. This study aims to investigate how age affects scleral biomechanical properties in a canine glaucoma model with ADAMTS10 mutation, whose extracellular matrix is concomitantly influenced by the mutation and an increased mechanical load from an early age. Biomechanical data was acquired from ADAMTS10-mutant dogs (n = 10, 21 to 131 month...

PURPOSE To determine the safety and efficacy of poly-N-isopropylacrylamide, a thermoresponsive adhesive, for sutureless sclerotomy closure in rabbits. METHODS Eight rabbits were randomized into three groups: short-term acute, mid-term chronic, and long-term chronic studies. A corresponding control group in which the scleral wounds were sutured by 6-0 vicryl sutures was assigned for each study...

PURPOSE We report a case of bilateral serous retinal detachment (SRD) associated with inferior posterior staphyloma (IPS) treated successfully with scleral shortening. PATIENT AND METHODS A 63-year-old woman presented with bilateral visual loss due to an SRD with IPS. The best-corrected visual acuity levels were 0.6 (20/30) and 0.5 (20/40) in the right and left eye, respectively. The patient ...

PURPOSE The aim of this study was to evaluate both the indications for and results of fitting the Jupiter Scleral Lens in patients with corneal abnormalities. METHOD This was a retrospective case review of 63 patients (107 eyes) fitted with scleral lenses between October 2009 and March 2011 at the UC Davis Eye Center. RESULTS Sixty-three percent of 107 eyes were in patients with keratoconus...

PURPOSE Biofilm formation is a problem for solid and sponge-type scleral buckles. This can lead to complications that require removal of the buckle, and result in vision loss due to related ocular morbidity, primarily infection, or recurrent retinal detachment. We investigate the ability of a covalent organo-selenium coating to inhibit biofilm formation on a scleral buckle. METHODS Sponge and...
