Ocular bubbly: a vitreoretinal update on the art of gases

The authors remind us of the revolutionary impact gases have had on retinal surgery. In 1938, Rosengren attempted to improve his retina repair surgical outcomes [1]. He discovered that suturing the retina or pressing externally on the sclera were not...

Risk of intraocular haemorrhage with new oral anticoagulants

The authors conducted a study to assess the risk of intraocular haemorrhage with warfarin dabigatran, rivaroxaban, apixaban. All reported cases of intraocular haemorrhage (vitreous, choroidal, or retinal) with warfarin and new oral anticoagulants (NOACs) (including dabigatran, rivaroxaban, apixaban) from the...

Two cases of acute syphilitic posterior placoid chorioretinitis

Syphilis has re-emerged as a significant public health concern, with the World Health Organization (WHO) estimating that 8 million adults aged 15–49 acquired syphilis in 2022. Untreated syphilis can have severe consequences, including cardiovascular, neurological and ocular complications. Ocular manifestations...

Type 3 CNV and anti-VEGF

The purpose of the study was to determine the differences between aflibercept and ranibizumab in terms of their therapeutic efficacy in the treatment of Type 3 neovascularisation. The authors highlight that the dominant mechanism for Type 3 neovascularisation development is...

Atrophy and anti-VEGF

The aim of this study was to investigate treatment factors, along with ocular and systemic factors for their association with macular atrophy (MA) incidence in eyes with neovascular age-related macular degeneration (nAMD) treated with anti-VEGF aflibercept or ranibizumab according to...

Optic nerve head perfusion response to reduced blood pressure and increased intraocular pressure

The purpose of this prospective study was to test the hypothesis that blood flow autoregulation in the optic nerve head has less reserve to maintain normal blood flow where there is a blood pressure induced decrease in ocular perfusion pressure...

Effect of intravenous mannitol in post vitrectomised eyes

The purpose of the study was to evaluate the effect of intravenous mannitol 20% on intraocular pressure in vitrectomised silicone-oil filled eyes. A prospective analysis of consecutive patients was undertaken with their fellow eyes taken as controls. Thirty-one patients were...

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...

Effect of refractive corneal surgery on IOP and glaucoma progression

Accuracy of intraocular pressure (IOP) measurement depends on the biomechanical properties of the cornea, including its thickness central corneal thickness (CCT) and keratometry (K). Fifty-six eyes of 56 patients with primary open angle glaucoma (POAG) who had a history of...

History An Afro-Caribbean woman, aged 30, with “scleral tattooing” for cosmetic reasons (subconjunctival dye injection), presented with bilateral upper and lower eyelid oedema for one week, and she also had restricted eye movement and blurry vision in her right eye....

Simulation in ophthalmology: a pedagogic viewpoint

The advent of simulation technology has enhanced modern medical training. The first utilisation of simulation was in 1929 where Edward Link used this concept to develop a mechanical flight simulator [1]. Industries such as aviation, nuclear power and the military...

Prognostication for uveal melanoma

The authors highlight the importance of using all available data in the prognostication of uveal melanoma (UM). Over recent years a number of molecular tests have emerged to allow clinicians to predict metastatic potential of UM. However, concordance between techniques...
