BACKGROUND/AIM To measure the positions of scleral-fixated intraocular lenses (IOLs) using anterior segment optical coherence tomography (OCT) and to evaluate the influence of the position of scleral-fixated IOL on the quality of vision. MATERIALS AND METHODS Twenty-six eyes of 26 patients were included in the study. The average age was 57.5 (11 to 78) years. Anterior segment images were take...

Purpose To investigate the effects of intraocular pressure (IOP) reduction on the eyeball shape in highly myopic eyes with high IOP. Methods This study included patients with an axial length ≥26.5 mm and high IOP ≥22 mmHg after receiving maximum medication, with successful trabeculectomy by a single surgeon, and who underwent swept-source optical coherence tomography (SS-OCT) examinations on ...

--Dried scleral rings of Opisthocomus, Galliformes, Cuculiformes, and other birds were examined to determine the pattern of ossicle overlap in Opisthocomus and its bearing on the phylogenetic relationships of this taxon. Although Opisthocomus shares a derived number of 12 scleral ossicles with cuculid Cuculiformes, the pattern of ossicle overlap differs. Nevertheless, fewer modifications are re...

Aims—To study the eVects of segmental scleral buckling and encircling procedures on tissue circulation in the human optic nerve head (ONH) and choroid and retina. Methods—Using the laser speckle method, the normalised blur (NB) value, a quantitative index of tissue blood velocity, was measured every 0.125 seconds and averaged over three pulses in the optic nerve head (NBONH) and choroid and ret...

AIMS To describe the outcome of patients with non-metastatic unilateral retinoblastoma with high risk histopathological features after primary enucleation, and to clarify the need and results of adjuvant therapy. PATIENTS AND METHODS From 1980 to 2001 adjuvant therapy was recommended only to patients with scleral involvement, post-laminar optic nerve involvement (PLONI) with either a positive...

PURPOSE Clones established from a human scleral cDNA library were systematically sequenced. Public database sequence comparisons were performed to generate a profile of genes expressed in the human sclera and identify candidate genes for inherited diseases with scleral involvement. METHODS A directionally cloned pCMV-PCR cDNA library was constructed from RNA isolated from scleras of human don...

AIMS To study binocular function in patients with longstanding asymmetric keratoconus. METHODS In 20 adult patients with longstanding asymmetric keratoconus managed with a scleral contact lens a full clinical and orthoptic assessment was performed with and without the scleral contact lens in the poorer eye. RESULTS All 20 patients had a corrected acuity of at least 6/9 in their better eye. ...

PURPOSE To compare the surgical outcomes of the two different methods used for Ahmed Glaucoma Valve (AGV) implantation between the donor scleral graft method and the partial-thickness scleral flap method. METHODS We retrospectively reviewed medical records of 28 eyes of 26 patients diagnosed as neovascular glaucoma followed by AGV implantation. Based on the surgical method, the included eyes ...

PURPOSE To describe a novel technique for toric intraocular lens (IOL) repositioning and fixation in the absence of adequate capsular support. METHODS Case report and literature review. RESULTS Two cases are presented with scleral fixation of a one-piece toric IOL (SN6AT series; Alcon Laboratories, Inc., Fort Worth, TX). In both cases, toric IOLs initially placed within the capsular bag bec...

BACKGROUND Rhinosporidiosis is a rare chronic infection of the mucous membranes caused by the Rhinosporidium seeberi. Approximately 15% of cases of rhinosporidiosis are ocular, occurring mainly in the tarsal conjunctiva. There are only 11 cases of scleral melt with staphyloma formation associated with bulbar conjuctival oculosporidiosis and none of them was associated with partial regression of...
