Impact on the corneal and anterior chamber characteristics after femtosecond laser cataract surgery

Femtosecond laser cataract surgery (FLACS) is being increasingly used in the preparation for cataract surgery. Benefits of circular capsulorrhexis and reduced phacoemulsification energy have been shown in the literature. This study was designed to assess the anterior chamber characteristics and...

Clinical predictors of proliferative sickle cell retinopathy

Sickle Cell Disease (SCD) is an inherited disorder resulting in production of Haemoglobin S (HbS), which aggregates in conditions of hypoxia, acidosis or hyperosmolarity. This leads to vascular stasis, thrombosis and ischaemia. The authors present a cross-sectional study (45 consecutive...

Environmental variations in endophthalmitis

In this retrospective cohort study, the authors looked at seasonal and environmental variations in 171 endophthalmitis cases out of 423,297 intravitreal injections. The incidence of this complication was not correlated to monthly snowfall, rainfall, or average temperature. There was no...

ANGPTL-4 inhibition reduces inflammation in diabetic retinopathy

Diabetic retinopathy (DR) is the most common cause of blindness in working-age humans, and numbers are rising due to increased cases of type 2 diabetes (T2D). T2D is associated with increased obesity and dyslipidaemia, which is a major risk factor...

Somatostatin protects retinal pericytes

Diabetic retinopathy (DR) is a complication of diabetes, caused by high blood sugar levels damaging the retinal microvasculature. Mechanisms, such as oxidative stress and deposition of advanced glycation end products, leads to glial cell activation and neuronal apoptosis. Pericytes, contractile...

Is an increased homocysteine level associated with greater risk of AMD?

Basic research studies have implicated homocysteine in causing vascular endothelial dysfunction and inflammation, and this has been borne out in large observational studies which suggested that elevated homocysteine is associated with increased risk of cardiovascular disease. In order to determine...

Akimba mice, a model of human diabetic retinopathy

Diabetic retinopathy (DR) is a major complication of diabetes and a growing problem as the systemic disease becomes more prevalent. DR develops insidiously from an asymptomatic form through to vascular damage that leads to oedema and breakdown of the blood-retinal...

Reduced blood flow and age-related macular degeneration

This was a prospective cross-sectional study assessing changes in blood flow velocity in patients with age-related macular degeneration (AMD) using a retinal function imager. Sixty eyes with wet AMD were compared to 53 control eyes and the average blood flow...

Corneal molecular and cellular biology for refractive surgeon

This is an interesting literature review that looks into the recent advances concerning the corneal molecular and cellular processes that are involved in the wound healing response after excimer laser surface ablation and LASIK surgery. It talks about the complex...

LASEK vs. epi-LASIK for myopia: meta-analysis

Previous studies have produced inconsistent conclusions on the relative benefits between LASEK vs. Epi-LASIK. LASEK uses 20% alcohol to separate an epithelial flap from the Bowman membrane. After ablation, the epithelial flap is repositioned onto the cornea. Epi-LASIK creates the...

Effect of preservative free fluoroquinolones on human corneal epithelial cells in vitro

Fluoroquinolones, including second generation (ofloxacin and ciprofloxacin), third generation (levofloxacin and tosufloxacin) and fourth generation (gatifloxacin and moxifloxacin), are a group of bactericidal agents used to treat multiple ocular infections. The third and fourth generation fluoroquinolones have enhanced Gram-positive activity...
