Comparison of corneal deformation parameters in keratoconic and normal eyes

This study set out to compare biomechanical properties between normal and keratoconic eyes. It was a retrospective study evaluating 89 eyes (47 normal, 42 keratoconic) and a validation arm of 72 eyes (33 normal, 39 keratoconic) using a high speed...

A refractive surprise after vitrectomy and capsulectomy

Figure 1: Right posterior capsule small aperture. We report a case of a pseudophakic patient who underwent vitrectomy and posterior capsulectomy. In spite of good visual acuity and absence of floaters, he was unhappy with the visual outcome. Case report...

Sebaceous gland carcinoma

This is a review of 241 patients diagnosed with periocular sebaceous gland carcinoma which investigates whether age at presentation influences either the clinical presentation or the outcomes of treatment. Twelve percent of patients were classified as young (<40 years old),...

Understanding vasoproliferative retinal tumours

Syed Irtiza Ali Shah explores this rare and unusual condition through a fascinating case presentation. Vasoproliferative tumours of the retina (VPTR) are a vascular mass with an associated exudative retinopathy alongside the presence of minimally dilated feeder vessels. This is...

AOP calls for ‘bold thinking’ in response to DHSC request for new minor and urgent eyecare service

The development of a standard specification for ICBs is welcome but ambition for a national approach ‘should not be sacrificed’.

Aberration measurements with manual or FLA cataract surgery

This study group compared the higher order aberrations (HOAs) between femtosecond laser-assisted cataract surgery (FLACS) and manual cataract surgery. Consecutive patients undergoing FLACS or manual cataract surgery with implantation of an intraocular lens from January 2017 to February 2018 were...

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...

Scheimpflug images and graft rejection

This study aimed to assess corneal changes using 360-degree Scheimpflug images and pachymetry readings to outline screening parameters, which define graft rejection. Seventeen eyes of 16 patients developed clinically manifest allograft rejection two to 42 months after surgery – those...

The College calls for funding for primary eye care services to be prioritised to address NHS ophthalmology backlog

The College of Optometrists has welcomed the extra funding promised for NHS England as a necessary step forward to help reduce waiting lists but calls on the government to prioritise funding towards primary eye care services to help tackle the...

Principles of contact lens fitting in keratoconus

Keratoconus is an ectatic condition of the cornea characterised by progressive conical distortion with irregular astigmatism, myopia and apical protrusion. Most cases progress slowly resulting in varying degrees of myopic astigmatism. Management of keratoconus includes spectacles, soft contact lenses, a...

Surgically induced astigmatism after cataract surgery

In this study, the authors analysed a dataset of 122 eyes of 122 patients with pre- and postoperative measurements of corneal astigmatism with IOL Master 700. A standardised 2.5mm superior corneal incision was utilised. The corneal power vector component in...
