Caffeine concentration in the vitreous after drinking coffee

Caffeine is known to penetrate many bodily fluids, including the vitreous. In this prospective study, investigators measured caffeine levels in vitreous samples from patients undergoing vitrectomy and epiretinal membrane peel. Patients were divided into habitual and non-habitual coffee drinkers. One...

Cataract extraction and microperimetry

In this study, the authors assessed retinal sensitivity before and after cataract extraction, in an effort to understand how lens opacities may affect microperimetry results in glaucoma and macular diseases. Thirty patients awaiting cataract extraction were examined and their lens...

Can the angle of origin of the ophthalmic artery predict embolic trajectory?

A retrospective, comparative case-control study was used to test the hypothesis that a risk factor for retinal versus cerebral infarct is the angular origin of the ophthalmic artery from the internal carotid artery. The study compared one group (n=28) who...

Carcinoid tumours

This is a retrospective review of 28 patients with carcinoid tumours affecting the orbit. The mean age at presentation of the orbital involvement was 62 years, with a slight female preponderance, and 21% had carcinoid syndrome. Proptosis and diplopia were...

Subconjunctival anaesthesia in vitreoretinal surgery

The authors present a technique that combines topical and subconjunctival anaesthesia for vitreoretinal surgery. In this ‘two-step’ procedure, three drops of proparacaine were applied to the conjunctival fornix, followed by subconjunctival lidocaine injected in three quadrants. This was compared with...

Acanthamoeba keratitis

This is a retrospective case series on medical records and corneal photographs of 40 eyes of 35 patients with acanthamoeba keratitis (AK, culture positive or with histopathological diagnosis). The mean age of onset was 30 ±15 years (younger in females)....

Quality of life of children and parents with and without a wide range of eye conditions

Fixation target position for increased limbus measurement accuracy with AS-OCT

The authors intended to determine the optimal gaze fixation points for lateral rectus and medial rectus muscle insertions using anterior segment - optical coherence tomography (AS-OCT) compared with intraoperative measurements. They recorded 46 lateral and 36 medial rectus muscles from...

Intraocular pressure changes following TOHM washout

This retrospective study between 2008 and 2019 of 110 eyes with primary open angle glaucoma (POAG), 33 eyes with ocular hypertension (OHT) and 43 eyes with uveitic glaucoma (UG) evaluated the changes in intraocular pressure (IOP) following topical ocular hypotensive...

Two-year interim safety results of the 0.2ug/day FAC intravitreal implant for the treatment of DMO

This is a 24-month interim prospective observational study of 95 previously steroid challenged patients (115 eyes) receiving intravitreal 0.2ug/day fluocinolone acetaid (FAC) implant for diabetic macular oedema (DMO) treatment. The mean IOP for pre- and post- FAC implants were stable,...

Posterior capsular rupture risk factors as reported in the European registry

In this cross-sectional review of the European Registry of Quality Outcomes for Cataract and Refractive Surgery (EUREQUO) including 2,853,376 patients and 31,749 cases with posterior capsular rupture (PCR), the authors observed a trend of reduction in PCR rate from 1.44%...

COVID-related mucormycosis

The authors report a retrospective case-control study of 73 patients with COVID-19 associated mucormycosis (CAM) between 1st March and 30th May 2021. They compared various factors between the two groups – patients who survived CAM (47 [64%]) and those that...
