Binocular single vision (BSV)

Introduction In this article I will try to summarise some of the definitions, tests and assessments performed in the strabismus clinic to assess patient binocular potential. This is a key feature of strabismus assessment, especially in adults, and it will...

Conservative surgical management of optic disc pit maculopathy

Four cases are presented in this case report that illustrates the option of conservative surgical management for optic disc pit complicated by maculopathy (ODP-M). Four men aged 24-67-years-old with no spontaneous resolution of ODP-M for a minimum of three months,...

Evaluation of keratometry with a novel colour LED corneal topographer

The Cassini topographer (i-Optics), which analyses corneal shape based on the reconstruction of specular reflections on 679 coloured LEDs, generates keratometry and is the new machine being compared in this study with other keratometry devices. The prospective comparative study included...

Investigation of PAX7 positive satellite cells in extraocular muscle surgery

PAX7 is a transcription factor and is expressed in non-active and activated satellite cells. It is needed for muscle progenitor function, survival and expansion. This study investigates the effect of recession/resection surgery on PAX7-positive satellite cells in extraocular muscles of...

Modification of surgery to reduce consecutive ET

Surgical treatment for recurrent exotropia (ET) predominantly depends on the primary surgery. Modification of surgical dose may be required in secondary procedures. The aim of this study was to compare surgical outcomes of modified and conventional secondary surgery using lateral...

Improved efficacy expected with second-generation microinvasive glaucoma surgery (MIGS) devices

Microinvasive surgical approaches to primary open-angle glaucoma (POAG) offer minimally traumatic options for effective intraocular pressure (IOP) reduction in appropriately selected glaucoma patients. Increases in laser trabeculoplasty rates and wider adoption of glaucoma drainage device filtration procedures, together with the...

Phakic iris clip lenses and endothelial cell loss

This retrospective observational study included long-term results on endothelial cell losses in highly myopic eyes, which underwent phakic iris-clip lens implantations. Included in the analysis were 113 eyes with mean preoperative spherical equivalent (SEQ) of -14.67 +/- 5.15 Diopters (D)....
