Usefulness of gonioscopy to investigate cause of corneal oedema after cataract surgery

A 72-year-old man with ocular hypertension presented three months after routine right phacoemulsification and toric intraocular lens (IOL) implantation with a two-week history of an irritated right eye and a sudden deterioration in right vision. His preoperative spherical equivalence was...

Topical insulin for neurotrophic ulcers

This retrospective case series described the use of topical insulin drops as an aid in treatment of refractory neurotrophic corneal ulceration in six patients. Insulin drops were prepared under sterile conditions from standard insulin preparations mixed with artificial tears containing...

Treatment of severe chronic ocular graft-versus-host disease

A retrospective study from Cologne, Germany, between November 2012 to March 2015, of 17 patients with graft-versus-host disease (GVHD) treated with 100% single use vials autologous serum eye drops in sealed system. Visual acuity, corneal staining, frequency of artificial tears,...

A comparison of colour vision tests in the presence of contrast sensitivity loss

This study analyses the effect of contrast sensitivity (CS) loss on colour vision (CV) testing, using a variety of colour vision tests. The authors used a computer model for CS loss to determine its effect on CV testing scores for...

Radiologic characteristics of cavernous venous malformations

This study is a retrospective review of cases with a preoperative radiologic diagnosis of cavernous venous malformations (CVMs) over 30 years. The aim of this study was to define imaging characteristics of CVMs, which will help differentiate these lesions from...

OCTA FAZ measurements in vein occlusion

Previous studies have confirmed that foveal avascular zone (FAZ) enlargement is correlated with visual acuity impairment in patients with retinal vein occlusion (RVO). This current study aimed to evaluate the OCT angiography parameters: the area of FAZ, foveal and parafoveal...

Keratoconus cone variants

This retrospective study examined correlation between three keratoconic parameters to further understand anatomy of keratoconic cones. Kmax and pachymetry of the thinnest point were obtained from the Pentacam scans. Decentration was calculated as distance from the corneal vertex to the...

Importing iron to the retina

In the retina, iron is particularly critical for the visual phototransduction cascade. In the retinal pigment epithelium (RPE), RPE65 activity leads to 11-cis-retinaldehyde, the photosensitive component of rhodopsin production and iron containing enzymes are necessary for disc replacement in photoreceptor...

A possible biomarker for diabetic retinopathy

Diabetic retinopathy (DR) is the most common form of diabetic eye disease, characterised by exudates, microaneurysms and haemorrhage. Early diagnosis is crucial for preventing visual loss. The risk of developing diabetic retinopathy is known to increase with age as well...

Does Acanthamoeba need bacteria to cause keratitis?

An animal study was carried out on 36 rabbits, whose corneas were inoculated with either Acanthamoeba castellanii alone, Pseudomonas aeruginosa alone or both pathogens together after a period of short (two hours) or long (six hours) co-incubation. The clinical severity...

Corneal lenticule allotransplant

This animal study looked at corneal lenticule allograft transplantation in rabbits. Seven rabbits underwent small incision lenticule extraction (SMILE) procedures, where their stromal lenticules were extracted and transplanted fresh into pre-prepared corneal stromal pockets of seven recipient eyes. Animals were...
