The FDA denies a petition by a former staffer to ban Lasik eye surgeries, saying the evidence presented in the petition isn't strong enough to support a revoked approval. The FDA last month shot down a petition filed by the former staffer who approved Lasik eye surgery, saying the evidence presented in the petition isn't strong enough to justify revoking pre-market approval and initiating a recall.

ConclusionsNo associations appeared between HIF1A SNPs and AMD, which were studied here for the first time; however, polymorphism rs1061170 of the CFH gene is associated with AMD in our population. (Source: Clinical and Experimental Ophthalmology)

Conclusion This mouse model of stroke has found that stimulating nerve cells in the part of the brain responsible for movement (the primary motor cortex) can lead to better blood flow and the expression of proteins that could promote recovery, as well as leading to functional recovery after stroke. But it remains to be determined whether a similar technique could be used in people who have had a stroke. The mice were genetically modified so nerve cells in the primary motor cortex produced an ion channel that could be activated by light. The nerve cells were then activated using a laser. To use this technique in humans, a gene coding for a light-sensitive channel would have to be introduced into nerve cells, possibly using gene therapy techniques. Gene therapy in people is very much in...

Conclusions SD-OCT is a suitable technique for iris thickness assessment. Thickness analysis must be carried out using a sectorial approach, taking into consideration anatomical variations existing between different iris regions. SD-OCT is a potentially useful tool for detecting iris thickness variations induced by pathological conditions such as Fuchs’ uveitis. (Source: British Journal of Ophthalmology)

Conclusions Retinal venous oxygen saturation was markedly reduced in untreated CRVO and was roughly halfway normalised during intravitreal ranibizumab treatment. Retinal artery oxygen saturation was not reduced in CRVO. Trial registration number NCT01360385. (Source: British Journal of Ophthalmology)

Conclusions The present results suggest that after phacoemulsification, the chance of development of CME in DR is more as compared to D. Moreover, the development of CME is significantly associated with decrease in antioxidant levels, increased ROS activities, hypertension, diabetic nephropathy, and hyperlipidaemia.

Conclusions Eyes with small volumes of intravitreal gas demonstrate significant IOP changes during atmospheric decompression in simulated flight. The presence of a scleral buckle significantly limits the magnitude of IOP change, suggesting that such patients can likely tolerate typical air travel without undue risk of dangerous IOP elevation.

Conclusions FND is effective in occluding established corneal vessels. Corneal microperforation is a potentially serious adverse event, but other adverse events, such as striae, whitening and intracorneal haemorrhages are reversible. It should be considered for established corneal vessels, and can be combined with antivascular endothelial growth factors. (Source: British Journal of Ophthalmology)

The development of analgesic interventions in paediatric surgical patients is often limited by the inherent difficulties of conducting large randomized clinical trials to test interventions in those patients. Regional anaesthesia is a valid strategy to improve postoperative pain in the adult surgical population, but the effects of regional anaesthesia on postoperative pain outcomes in paediatric patients are currently not well defined. The main objective of the current review was to systematically evaluate the use of regional anaesthesia techniques to minimize postoperative pain in paediatric patients. A systematic search was performed to identify randomized controlled trials that evaluated the effects of the regional anaesthesia techniques on postoperative pain outcomes in paediatric surg...

Conclusions CBS is of longer duration than previously suspected with clinically relevant consequences in a third of those affected. Interventions that reduce the frequency, duration or fear of individual hallucination episodes and education prior to hallucination onset may help reduce negative outcome.

A 42-year-old man noted sudden onset of blurriness in his left eye and dropped his iPod from his right hand while jogging. In the emergency room, it was noted that visual blurring resolved with right eye closure, but his ophthalmologic examination was otherwise normal. He had subtle right nasolabial fold flattening and right arm pronator drift. His examination was otherwise normal. He reported no headache, neck pain, prior trauma, prior transient neurologic deficit, or palpitations. He took no medications and did not smoke, drink alcohol, or use illicit drugs.

Conclusions The repeatability and reproducibility of AL-Scan was excellent for all parameters, except WTW and PD. Excluding WTW, good agreement was found between the AL-Scan and IOLMaster. The 2.4-mm diameter K value may be the most reliable choice for calculation of IOL power with the AL-Scan. (Source: British Journal of Ophthalmology)

A 21-year-old man was in a motor collision, resulting in skull fractures and subsequent craniectomy (figure). When he was able to communicate, 60 days after injury, he reported vertical oscillopsia and a throbbing sensation around his left eye. Examination revealed monocular left orbital pulsations (video on the Neurology® Web site at Neurology.org). Orbital pulsations can result from a cavernous carotid fistula, orbital venous varix, orbital arteriovenous malformation, orbital tumor, intraorbital ophthalmic artery aneurysm, tricuspid regurgitation, or orbital wall defects associated with neurofibromatosis. Orbital pulsations have been rarely reported due to incompetent orbital bone structure. This case illustrates orbital pulsations associated with postsurgical, posttraumatic oscillop...
