Corneal refractive surgery may be more successful in eyes in which the cylinder mainly originates from the anterior cornea; therefore, in candidates for refractive surgery, surgeons should carefully assess the interaction between topographic, refractive and ocular residual astigmatism (ORA) to identify those at high risk for having significant differences between subjective cylinder and topographic astigmatism.
Patients with advanced glaucoma have higher oxygen saturation in venules and lower arteriovenous difference in oxygen saturation compared with healthy individuals. The decrease in arteriovenous difference in patients with severe glaucoma may be related to lower oxygen consumption secondary to neuropathy
According to Prof. Lois, peeling the internal limiting membrane when operating on patients with idiopathic full-thickness macular hole improves the outcomes of surgery. This article reviews her recent review study and highlights the outcomes.
The membranes found on the retinal surface can cause visual symptoms in various conditions and a patient's vision can often be improved with surgical removal of these membranes, according to Mr Mahmut Dogramaci (The Lister Surgicentre, Lister Hospital, Stevenage, UK).
Ultra-widefield fluorescein angiography may help improve treatment in patients with recalcitrant diabetic macular oedema by visualizing areas of peripheral nonperfusion that can benefit from targeted photocoagulation.

In this article, Dr Amparo discusses the role of tear osmolarity measurements in the assessment of dry eye disease and the patient's response to therapy.
Phaco tips are an important part of the phacoemulsification tool set. Dr Bazzigaluppi performed a comparison on a traditional and newer tip to evaluate the efficiency, safety and stability differences. Here, we explore his reasons for performing this study.
Here, Dr Cadarso discusses how he targets vertical coma specifically through adaptation of the Keraring ICRS implantation technique.
In this article, the authors report on a case of two brothers with genetically proved Leber's disease associated with the rarer mutation G3635A, which is the only family case encountered in Bulgaria thus far.
Nocturnal IOP measurements are critical in evaluating drugs, according to Professor Cordeiro speaking at the 4th World Congress on Controversies in Ophthalmology.
This article discusses the prognostic factors and options in the surgical management of rhegmatogenous retinal detachments associated with macular holes.
According to this article, not all patients may benefit from routine testing prior to surgery. A better option may be selective screening for those at greatest risk for adverse systemic events.
In this article, Dr Akpek discusses the pros and cons of currently available options in the management of meibomian gland dysfunction.
Post-refractive surgery dry eye is an unwanted yet reoccurring problem for surgeons, according to Dr Cummings. In this article, he discusses the pre-op approach taken in his practice, which leads to a more certain diagnosis and higher patient satisfaction rates.
Various issues impact the effectiveness of population screening for open-angle glaucoma (OAG). However, use of ethnicity-specific normative databases for structural tests may improve their diagnostic performance, said Dr Mingguang He, PhD.
The European Academy of Optometry and Optics (EAOO) has launched its first 3-year strategic plan for 2014 through 2016.
A research initiative to develop new techniques for early detection of diabetic retinopathy (DR) is currently under way at the University of Lincoln, UK.
Retinal injury following childhood exposure to laser 'toys' is a public safety concern, according to the first case series of such injuries, which has recently been published.
Premature infants with very low birth weight who receive an intravenous fat emulsion containing fish oil are less likely to develop retinopathy of prematurity (ROP), according to a recent study.
IOP measurements obtained with the rebound tonometer (Icare Pro) are more comparable to those achieved with the Goldmann applanation tonometer than those obtained with ultra-high-speed Scheimpflug technology, according to a recent study.
A novel, patented multi-component IOL (IVO Lens, InfinitVision Optics) allows for postoperative adjustments for changes in refraction, making it an ideal solution for paediatric cataract surgery, according to a recent report.
The combination of sutureless coaxial microincision cataract surgery and 23-gauge vitrectomy confers many advantages, including less wound leakage, good anterior chamber stability, safety, decreased inflammation and faster rehabilitation after surgery, according to the authors of a study published recently in Retina: The Journal of Retinal and Vitreous Diseases.
Patients who develop advanced age-related macular degeneration (AMD) undergo a precipitous loss of vision, concluded the researchers of this study recently published in the Journal of the American Medical Association Ophthalmology.
Patients with optic disc swelling caused by nonarteritic anterior ischaemic optic neuropathy (NAION) have less light retardance compared with patients with optic disc swelling caused by papilloedema or optic neuritis.
Collagen crosslinking (CXL) in patients with progressive keratoconus was found to be effective after 2 years in improving uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), topographic metrics, and most corneal higher-order aberrations, according to a study published in Cornea: The Journal of Cornea and External Disease. Researchers noted that there was a significant reduction in apical keratometry, which directly correlated with improvements in visual acuity
Autologous serum (AS) eye drops on the ocular surface of patients with bilateral severe dry eye improved not only ocular surface dryness, but decreased damage of the epithelium as well, as measured by clinical, laboratory, and subjective criteria, according to results from a study recently published in Current Eye Research
Steroid-induced central serous chorioretinopathy (CSC) may only occur in select patients who are vulnerable, rather than having a dose-dependent effect, according to a recent study published in Investigative Ophthalmology & Visual Science
Patients with pseudophakic eye who have undergone cataract will have greater access to fluocinolone acetonide (Iluvien, Alimera Sciences) for the treatment of chronic diabetic macular oedema (DME) that is considered refractive to available therapies. The National Institute for Health and Care Excellence (NICE) has published a final guidance recommending fluocinolone acetonide, making it available for patients through the National Health Service (NHS).
Two treatments with selective laser trabeculoplasty (SLT) in the same area of the trabecular meshwork (TM) do not significantly affect IOP, compared with two SLT treatments in differing areas, according to a recently published study.
