conclusions by using the normal angle kappa determined in this study, pseudodeviations can be identified more precisely in those who might undergo keratorefractive surgery. results a total of 977 healthy participants who aged 18 to 45 years were included consecutively. the study population consisted of 614 females and 363 males. the average angle kappa was 5.00º ± 1.36º at 240.21º ± 97.17º in m...

The second part of the book details many of Guthrie’s lectures and writings. Following his wartime experiences, he specialised in ophthalmic surgery and wrote three textbooks on eye surgery. He progressed to become President of the Royal College of Surgeons of England on three separate occasions. He enabled the end of “body snatching” by the Anatomy Act of 1832. This remarkable man was multi-li...

Purpose. To evaluate the diurnal intraocular pressure (IOP) in eyes after vitrectomy compared to that of healthy eyes. Methods. Twenty-one patients who had undergone vitrectomy and 21 age- and gender-matched normal controls were enrolled during the same period. We measured the diurnal IOP every two hours between 9 a.m. and 11 p.m. in all patients who were admitted for cataract surgery. Patients...

Ophthalmic surgeons require years of training and continuous practice to successfully manipulate the delicate tissues of the human eye. Development of the fine motor skills is a crucial component of this training. Virtual eye surgery simulators have come on the market in recent years leveraging the advantages of virtual procedures. However adoption is limited by the high initial investment and ...

PURPOSE   Many questionnaires for the measurement of visual impairment exist. One, the Houston Vision Assessment Test (HVAT), takes a different approach: the patient is asked to rate overall impairment and the proportion attributed to vision, then through multiplication the visual and non-visual (physical) impairments are calculated. The purpose of this study was to determine whether the scores...

rous attack, in your July issue, on my article headed " Sixtyone eye operations in one day" and which yoti were kind enough to publish about 2 years ago. The references he quotes to belittle my results, viz., (a) 1903 statistics, a period when conjunctival asepsis was almost in its infancy and operative technique was not so widely possessed, (b) Norris and Olivers, Vol. Ill, a system on ophthal...

pseudoaneurysms of the ascending aorta, which are rare and life-threatening complications in cardiovascular surgeries, can be caused by the bentall procedure. we describe a 44-year-old woman, who had a medical history of acute aortic dissection (type a) and the bentall procedure and was admitted because of exertional dyspnea, edema of the lower extremities, ascites, and holosystolic murmur in t...

background: surgical treatment of a ruptured abdominal aorta aneurysm (raaa) continues to present a significant challenge to surgeons. there are some patient factors such as age and gender that cannot be changed, and comorbid conditions can be optimized but not eliminated.  the purpose of this study was to identify the risk factors affecting high mortality after the surgical repair of an raaa. ...

background in some hospitals, urinalysis is done routinely for all patients scheduled for cardiac surgery. occasionally pyuria or bacteria is reported in the microscopic urinalysis of these patients that are clinically asymptomatic for urinary tract infections. objectives we were seeking answer to this question: is the presence of a different number of bacteria in preoperative microscopic urina...
