One-year visual outcome of secondary piggyback pinhole device implantation in pseudophakic eyes with irregular corneal astigmatism and iris trauma.

Purpose: Retrospective case series evaluating the efficacy and safety of implanting XtraFocus pinhole device in pseudophakic patients with irregular corneal astigmatism with concurrent or standalone iris defect.

Methods: Electronic case records were searched for: uncorrected distance visual acuities (UDVA) and corrected distance visual acuities (CDVA), automatic or manifest refraction and spherical equivalent (SE). All main outcomes were evaluated preoperatively and postoperatively at 1, 3, 6, 9 and 12 months, along with patients' satisfactory outcome and complications.

Refractive surprise after routine cataract surgery with multifocal IOLs attributable to corneal epithelial basement membrane dystrophy.

We describe two patients in whom postsurgical refractive error occurred after routine refractive lens exchange cataract surgery with multifocal intraocular lens insertion most likely attributable to the presence of underlying corneal epithelial basement membrane dystrophy (EBMD). In Case 1, there was an unexpected hyperopic postoperative spherical equivalent refractive error of +1.50 diopters and in Case 2, a cylindrical refractive error of 2.

Porous Versus Nonporous Orbital Implants After Enucleation for Uveal Melanoma: A Randomized Study.

Purpose: To compare hydroxyapatite with acrylic implants after enucleation for uveal melanoma with respect to eyelid position, ocular motility, implant complications, and patient satisfaction.

Methods: Patients undergoing primary enucleation for uveal melanoma between May 2005 and November 2012 at the Liverpool Ocular Oncology Centre, United Kingdom, were randomized between hydroxyapatite and acrylic implants. Questionnaires were sent to patients and ocularists to comment on the main outcomes.

A case of misconstrue proptosis.

This case illustrates an overlooked metastatic lung carcinoma to the orbit. The rapid onset of symptoms and oedema mimicked a cellulitis. The patient was initially treated with a broad-spectrum topical and intravenous antibiotic therapy.

Ascorbate elevates perfusion pressure in the bovine extraocular long posterior ciliary artery: role of endothelium-derived hyperpolarizing factor (EDHF).

Ascorbate blocks agonist-induced, endothelium-derived hyperpolarizing factor (EDHF)-mediated vasodilatation in the bovine perfused ciliary artery and this is associated with a rise in perfusion pressure. We now report the origins of this ascorbate-induced rise in perfusion pressure. In segments of ciliary artery perfused at 2.
