Prism adaptation test in acquired non-accommodative esotropia

This study investigated factors related to the increase in prism adapted angle in patients with acquired non-accommodative comitant esotropia (ANAET) who had strabismus surgery based on the results of a short prism adaptation test (PAT) and evaluated their outcomes. Short...

Clinical features of basic acquired nonaccommodative esotropia requiring surgery

Basic acquired nonaccommodative esotropia (BANAET) is a concomitant esotropia occurring after the age of six months without significant refractive error or accommodative element. Esotropia is similar for both near and distance and children have prior binocular single vision. The purpose...

Differential inhibition of EAU by CTLA4 and IL-6

Cytotoxic T lymphocyte antigen-4 (CTLA4) binds both CD80 and Cd86 and inhibits T lymphocyte activation via CD28. Il-6 is a pleiotropic cytokine that has been associated with many autoimmune conditions including uveitis. Blockade of these molecules by either CTLA4-Ig, a...

Congenital cranial dysinnervation disorders (CCDDs)

The term congenital cranial dysinnervation disorder (CCDD) was introduced by Gutowski et al. in 2003 to describe strabismus conditions that result from developmental error in innervation of some of the extraocular muscles. Examples of these conditions include Duane’s syndrome and...

Biometry and IOL choice errors

In the next instalment of this series I focus on problems associated with biometry and intraocular lens (IOL) selection for cataract surgery. I have taken previous medicolegal cases I have dealt with and tried to extract some learning points and...

Review of non-arteritic anterior ischaemic optic neuropathy

This article reviews the risk factors, clinical presentation and therapies that have been investigated for non-arteritic anterior ischaemic optic neuropathy (NAAION). Additionally, it provides an update from recent rodent and primate models, offering a new insight into the pathophysiology of...

Cambridge Ophthalmological Symposium 2024: Evolution and the Eye

by Anushka Irodi, Y5 Medical Student, University of Cambridge, UK. The 52nd Cambridge Ophthalmological Symposium, a renowned two-day national meeting, took place on September 5th and 6th, 2024 at St John’s College, Cambridge, UK. It brought together international leading minds...

Bilateral medial rectus recession outcomes for acute acquired comitant esotropia vs infantile esotropia

In this study, the aim was to describe the surgical dose response of bilateral medial rectus muscle recession (MRR) in acute acquired comitant esotropia (AACE), compared to infantile esotropia (IET). This was a retrospective study of 114 patients; 39 AACE...

Direct endoscopic probing for congenital lacrimal duct obstruction

The most common treatment for congenital lacrimal duct obstruction (CLDO) is probing, which is traditionally a blind procedure. Previous literature reports success rates between 78-92%. The authors of this retrospective non comparative case series reviewed the success rates of probing...

Medial rectus spontaneous reattachment after surgery

The authors report necropsy findings following free tenotomy of the medial rectus (MR) muscle in six postnatal monkeys. Bilateral MR tenotomy was performed producing alternating exotropia of 30-70 degrees with no adduction beyond primary position. Over follow-up, all showed reduction...

Changes in corneal endothelial layer after strabismus surgery

The purpose of this study was to investigate the changes in the corneal endothelial layer by specular microscopy after surgery in patients with horizontal and oblique strabismus. Eighty-three eyes of 56 patients were evaluated prospectively. There were three subgroups: one...

Outcomes of horizontal muscle transplantation

The authors propose the technique of transplantation of the resected muscle segment to the previously recessed muscle for correction of residual / recurrent strabismus in order to restrict surgery to one eye and avoid large recession of previously recessed rectus...
