Enzymatic clearance of anterior chamber infiltrate in uveitis

Aqueous humour (AH) which fills the anterior chamber (AC) of the eye provides nutrients to the cornea and the lens. Clearance of cellular and particular matter from AH is necessary for good visual acuity. In part this is achieved by...

Microperimetry of subretinal drusenoid deposits

Subretinal drusenoid deposits (SDD), originally termed ‘reticular pseudo-drusen’, have recently been identified by histology and optical coherence tomography (OCT) as aggregations located in the subretinal rather than the sub retinal pigment epithelium (RPE) space. These deposits affect the amount of...

The decline in attentional visual fields in the Salisbury Eye Evaluation Driving Study

The purpose was to document changes in attentional visual field (AVF) over time and analyse the possible baseline characteristics predicting a decline in AVF size over time. Data was taken from a sample of 968 individuals. The authors found a...

Macular oedema after cataract surgery in diabetic patients

The authors describe a multi-centre prospective observational study of 293 participants that underwent cataract surgery who all had diabetic retinopathy without definite central-involved macular oedema.

Pars plana vitrectomy for vitreomacular traction syndrome

This paper presents a meta-analysis and systematic review of the safety and efficacy of vitrectomy for vitreomacular traction (VMT), based on 21 eligible articles from 460 identified. A strength of this study is that it provided pooled analysis across a...

Radiation maculopathy

This is a retrospective non-randomised study of 13 consecutive eyes of 13 patients affected by radiation maculopathy secondary to eye irradiation for primary uveal melanoma (Iodine-125 brachytherapy). All patients were treated with a single intravitreal 0.7mg dexamethasone implant and full...

IINS function

Lens surgery in patients with lens subluxation misdiagnosed as primary angle-closure glaucoma

Lens subluxation can be caused by many conditions including Marfan syndrome and other hereditary conditions, and blunt trauma. Lens displacement can cause pupillary block and angle closure. This is commonly misdiagnosed as primary angle closure glaucoma (PACG), which can lead...

Surgical outcomes after trauma-induced cataract extraction

This study evaluated outcomes in children aged less than eight years with corneal laceration and traumatic cataract who had cataract extraction one to eight weeks after primary corneal wound repair. This was a retrospective study of 47 eyes of 47...

Infantile vertical nystagmus

The authors describe the clinical characteristics and long-term outcomes of infants who presented with isolated vertical nystagmus in infancy, age-appropriate visual behaviours and unremarkable neuroimaging studies. The study included eight patients presenting at <1-year-old. All had age-appropriate behaviour. At presentation...

OCT in microtropia

The aim of this study was to assess whether OCT could be useful in detecting and documenting fixation in children with microtropia. The study used spectral domain OCT (Cirrus) in 15 patients (10 female, five male) and 10 control eyes....
