Orbital abscess following posterior subtenon steroid injection
The authors report a case of orbital cellulitis following posterior subtenon injection of triamcinolone acetonide. A 57-year-old male patient with a background of complicated cataract surgery underwent vitrectomy with explantation of dislocated intraocular lens and insertion of anterior chamber lens....
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...
Trabeculectomy ab interno (trabectome)
This retrospective study examines the outcome of trabectome surgery in nine phakic patients with Posner-Schlossman syndrome with uncontrolled IOP >30mmgHg. Cytomegalovirus (CMV) DNA was verified by polymerase chain reaction (PCR) in aqueous humour samples. Patients were treated with oral valganciclover...
Nanofiber-based hydrogels prevent capsular opacification
Lens refilling is the replacement of the lens with a silicone polymer in an otherwise intact lens capsule. However, capsular opacification (CO), resulting in reduced visual acuity, is a major complication of these injectable accommodating lenses. Opacification is due to...
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...
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...
Limbal melanocytes and the stem cell niche
The cornea is continually regenerated to maintain clear vision, due to a population of stem cells located in the limbal region between the cornea and the conjunctiva. These limbal stem cells (LESC) reside in crypts in structures called the Pallisades...
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...
Optic nerve head perfusion response to reduced blood pressure and increased intraocular pressure
The purpose of this prospective study was to test the hypothesis that blood flow autoregulation in the optic nerve head has less reserve to maintain normal blood flow where there is a blood pressure induced decrease in ocular perfusion pressure...
International orthoptics for stroke
The purpose of this study was to consider the practice of orthoptists internationally in care provision for post stroke visual impairment through an international survey. An online survey of 30 questions was circulated via the International Orthoptic Association and completed...
A tarso-conjunctival flap for paralytic ectropion
This is a review of 110 patients with paralytic ectropion who underwent a lateral tarso-conjunctival flap procedure. The technique involves fashioning a 4-8mm wide lateral tarso-conjunctival flap in a similar way to a lateral Hughes flap. This is then sutured...
