My Top Five: Visionary inventions in ophthalmology

When we see how technologically forward and advanced modern-day medicine is, we forget that it is also an age-old, ancient profession with a rich, intriguing history that we remain unaware of. Ophthalmology in particular has always been at the forefront...

25 years of OCT

David Huang first described optical coherence tomography (OCT) in 1991, in his seminal paper on the subject in Science. This method developed the work of others on ophthalmic interferometry, which essentially showed that measuring reflected light could be used to...

Use of RAPDx device with optic nerve disease

The authors have previously reported on use of the RAPDx device for evaluating relative afferent pupillary defects (RAPD). RAPDx objectively determines the magnitude of RAPD by presenting light stimuli alternately to pairs of eyes with laterality. The parameters of amplitude...

The role of spectral-domain OCT RNFL in revealing a pituitary adenoma with atypical visual fields

Pituitary adenomas classically cause bitemporal hemianopia by compressing the optic chiasm. However, in some cases, the pattern of visual field loss may be atypical and mimic homonymous hemianopia, depending on the direction and extent of tumour expansion. Spectral-domain optical coherence...

Hering’s response in ptosis surgery

his is a prospective study of the Hering’s response in patients undergoing Muller’s muscle-conjunctival resection (MMCR) ptosis surgery, with a particular reference to the accuracy of preoperative phenylephrine testing. Patients with unilateral ptosis were assessed clinically preoperatively, in the immediate...

Orbis eye health programme integrated into school curriculum in Nepal

Leading eyecare charity Orbis and Nepal’s National Society of Comprehensive Eye Care (NNJS) have worked together since 2019 to implement a programme called REACH (Refractive Error Among Children) in Eastern Nepal.

Diagnosis and management of IV cranial nerve palsy

Aetiology: Trochlear nerve palsy can be divided into acute or congenital. Congenital trochlear nerve palsy is usually noted in childhood with development of abnormal head posture. Various pathologies can lead to acute IV nerve palsy, most commonly trauma. Other causes...

Bilateral LR recession for DRS

This study reports the use of bilateral lateral rectus (LR) recessions instead of unilateral LR recession for unilateral exotropic Duane’s retraction syndrome (DRS) with abnormal head posture. This was a retrospective study of seven patients; five female and two male....

Optegra launches new fellowship programme

Leading eye health care group, Optegra, is proud to announce the appointment of its first Fellow, Mr Fadi Alfaqawi, as it unveils its Cataract and Refractive Surgery Fellowship Programme.

Results of surgery in a case of FMNS

The authors present the effects of the tenotomy and reattachment procedure on a patient with accommodative strabismus and fusion maldevelopment nystagmus syndrome (FMNS) who did not require strabismus correction. The ocular motility study of this patient allowed the opportunity to...

Optical quality difference between monofocal and multifocal intraocular lenses

It is well known that multifocal intraocular lenses (IOLs) can generate more than one focus to restore distance and near vision, but patients may experience adverse optical phenomena such as decreased contrast sensitivity and induced glare or halos. The authors...

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)....
