Surgical complications of ReLEx

Femtosecond laser refractive lenticule extraction (ReLEx) is a novel procedure for treatment of myopia and myopic astigmatism, which eliminates the use of microkeratome and excimer laser. Currently there are two techniques: FLEx – femtosecond lenticule extraction (similar to conventional LASIK)...

RPTP-σ increases pro-MMP activity in a trabecular meshwork cell line following oxidative stress conditions

This study aims to outline the role of phosphatases in the aqueous drainage system by overexpressing receptor tyrosine phosphatase sigma (RPTP-σ) in a human normal trabecular meshwork cell line and describing its effect on subtypes of matrix metalloproteinases (MMP) and...

Systemic anti-inflammatory versus fluocinolone acetonide intraocular implant

In the Multicenter Uveitis Steroid Treatment (MUST) trial, 255 patients with intermediate uveitis, posterior uveitis or panuveitis were randomised to either fluocinolone acetonide intraocular implant or systemic corticosteroid therapy which was supplemented with immunosuppression if required. Patients were followed up...

Ozurdex wound leakage

This letter to the editor describes two cases of wound leakage after Ozurdex injection. The first case is a man who had four previous injections for an underlying diagnosis of chronic serpiginous choroiditis, who was also on a course of...

PD-1 and retinal ganglion cell death

Death of retinal ganglion cells (RGC) in conditions like glaucoma leads to permanent visual loss. RGC death can be due to the initial stress such as raised intraocular pressure or secondary to mechanism such as oxidative stress. Programmed cell death-1...

Amblyopic choroidal thickness

The authors studied choroidal thickness in 38 paediatric cases (76 eyes) with unilateral amblyopia to evaluate the differences between amblyopic and fellow eyes, and compare them with 19 healthy control subjects (38 eyes). Anisometropic amblyopia was present in 17 cases...

Uveitis in the elderly

This study from Turkey evaluated the causes and clinical characteristics of uveitis in elderly patients. Data from 90 eyes of 68 patients aged 60 years and older were reviewed. Anterior uveitis was present in 75% (33% of these had keratouveitis),...

Lucentis for pseudophakic CMO

Pseudophakic cystoid macular oedema (CMO) develops angiographically in up to 20-30% after uneventful phacoemulsification. This study aimed to evaluate the potential efficacy and safety of intravitreal ranibizumab in patients with pseudophakic CMO after cataract surgery. Seven eyes were included in...

The impact of conjunctivochalasis on dry eye symptoms and signs

The study aimed to draw a relationship between conjunctivochalasis and dry eye symptoms via a dry eye questionnaire (DEQ5), as well as signs such as tear osmolarity, tear break up time, corneal staining, Schirmer score, meibomian gland dropout, eye lid...

Sustained elevation of extracellular ATP in chronic glaucoma

Although adenosine 5′-triphosphate (ATP) release from retinal neurons and astrocytes has been demonstrated in short-term increases in intraocular pressure (IOP); such as in aqueous humor of humans with primary acute angle closure glaucoma, the response in chronic IOP elevation was...

Neuro-ophthalmological symptoms in patients with cerebral venous sinus thrombosis

The authors of this article have evaluated the neuro-ophthalmological symptoms of 49 patients with cerebral venous sinus thrombosis. They have evaluated the onset of the disease as well as the symptoms reported. The authors present extensive clinical information for individual...

Binocular summation with low contrast

The magnitude of binocular summation was investigated in normal control subjects using four different letter charts of varying type with fixed and variable contrast levels and spatial frequency to determine which tests most readily reveal binocular summation in normal subjects....
