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...

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...

Treatment options for septic cavernous sinus thrombosis

Septic cavernous sinus thrombosis is a rare but serious complication of infection of the cavernous sinuses. Potential therapies include antibiotics, corticosteroids and anticoagulation, as well as surgical intervention for source control of the infection. The authors report that there is...

Treat and extend for PCV

This South Korean study investigated the efficacy of a treat and extend regimen (TER) using ranibizumab to treat polypoidal choroidal vasculopathy (PCV). Twenty-nine eyes were included in this retrospective case note review. Of these, five eyes had been treated with...

Platelet rich fibrin membrane for descemetocele

This case series described the use of a novel technique in the treatment of descemetocele. Three patients developed descemetoceles following infective keratitis with impending risk of corneal perforation. Platelet rich fibrin (PRF) membrane was prepared using 8ml of fresh venous...

Systematic review on vergence neural pathways

A full systematic review of the literature was carried out by the authors, to identify literature available on vergence neural pathways and associated disorders. The review included articles related to vergence neural pathways, along with articles that discussed the anatomy,...

MISS vs. fornix approach

The objectives of this study were to compare minimally invasive strabismus surgery (MISS) with the fornix approach in paediatric horizontal strabismus surgery (<12 years) and to evaluate early postoperative inflammation, visual acuity and operating time after a four-year training period...

Myopia-protective against diabetic retinopathy

This meta-analysis evaluates the current evidence of the relationship between myopia and diabetic retinopathy (DR) risk. A systematic search was performed up to April 2015. Three models were used to assess the association between myopia and risk of DR: axial...
