Lay summary — Los Angeles Times September 4, White light is an example of a broadband source with lower power. OCT is based on low-coherence interferometry. October Any light that is outside the short coherence length will not interfere. An imaging approach to temporal OCT was developed by Claude Boccara's team in[24] with an acquisition of the images without beam scanning. Light with broad bandwidths can be generated by using superluminescent diodes or lasers with extremely short pulses femtosecond lasers. Bibcode : OExpr.

Intravascular OCT has been investigated for use in neurovascular applications, too, including imaging for guiding endovascular treatment of ischemic stroke and brain aneurysms. Myocardial perfusion imaging. The drawbacks of this technology are found in a strong fall-off of the SNR, which is proportional to the distance from the zero delay and a sinc-type reduction of the depth dependent sensitivity because of limited detection linewidth.

In particular, if the slant of the palpebral fissure is raised and the horizontal dimension of the palpebral fissure is short, adjusting the slant of the pal- pebral fissure through lateral canthoplasty can achieve an enlargement of eye width and smoother features. Depending on the patient’s condition, even better results can be achieved if this procedure is performed in conjunction with other procedures, such as double eyelid- plasty, epicanthoplasty, eye roll formation surgery, fat graft, and facial bone contouring sur- gery. In this paper, the authors will introduce in detail their surgical method for a cosmetic lateral canthoplasty that lengthens the lateral canthal angle and corrects the outer tail of the eyes, in order to ease the unfavorable impression.

Please improve this article by introducing more precise citations. (May 2011) Cataract surgery Intervention Cataract in Human Eye- Magnified view seen on examination with a slit lamp ICD-9-CM 13.19 MeSH D002387 Cataract surgery is the removal of the natural lens of the eye (also called "crystalline lens") that has developed an opacification, which is referred to as a cataract. Metabolic changes of the crystalline lens fibers over time lead to the development of the cataract and loss of transparency, causing impairment or loss of vision. Many patients' first symptoms are strong glare from lights and small light sources at night, along with reduced acuity at low light levels. During cataract surgery, a patient's cloudy natural lens is removed and replaced with a synthetic lens to restore the lens's transparency.[1] Following surgical removal of the natural lens, an artificial intraocular lens implant is inserted (eye surgeons say that the lens is "implanted"). Cataract surgery is generally performed by an ophthalmologist (eye surgeon) in an ambulatory (rather than inpatient) setting, in a surgical center or hospital, using local anesthesia (either topical, peribulbar, or retrobulbar), usually causing little or no discomfort to the patient. Well over 90% of operations are successful in restoring useful vision, with a low complication rate.[2] Day care, high volume, minimally invasive, small incision phacoemulsification with quick post-op recovery has become the standard of care in cataract surgery all over the world.

  • Nystagmus and Ocular Oscillations in Infancy and Childhood Richard W
    9 Nystagmus and Ocular Oscillations in Infancy and Childhood Richard W. Hertle ye care practitioners may be among the first to evaluate Einfants and children with involuntary ocular movements. Pediatric ophthalmologists may, in fact, see more patients with nystagmus than any other specialist because of the frequent association of nystagmus with strabismus.9,16,20,42,54,61,75 Nystag- mus may be covered less frequently in literature and research because there is less we understand or can do about it, compared to strabismus or other childhood eye diseases. HISTORICAL PERSPECTIVE Nystagmus is a rhythmic, involuntary oscillation of one or both eyes. The term comes from the Greek word “nystagmos,” to nod, drowsiness and from “nystazein,” to doze; probably akin to Lithuanian “snusti,” also to doze. Using the information obtained from a complete history, physical examination, and radiographic and oculographic evaluations, more than 40 types of nystagmus can be distinguished (Table 9-1). Some forms of nystagmus are physiological whereas others are pathological. Although the nystagmus is typically described by its more easily observable fast (jerk) phase, the salient clinical and pathological feature is the presence of a slow phase in one or both directions. Clinical descriptions of nystagmus are usually based on the direc- tion of the fast phase and are termed horizontal, vertical, or rotary, or any combination of these (Fig. 9-1). The nystagmus may be conjugate or dysconjugate, indicating whether the eyes move 289 290 handbook of pediatric neuro-ophthalmology TABLE 9-1.

OBJECTIVE: Dynamic visual inputs can cause visual vertigo (VV) in patients with vestibulopathy, leading to dizziness and falls. This study investigated the influence of VV on oculomotor responses. METHODS: In this cross-sectional, single-blind study, with experimental and control groups, 8 individuals with vestibulopathy and VV, 10 with vestibulopathy and no VV, and 10 healthy controls participated. Oculomotor responses were examined with 2- dimensional video-oculography. Participants were exposed to dynamic visual inputs of vertical stripes sweeping across a screen at 20 deg/sec, while seated or in Romberg stance, with and without a fixed target. Responses were quantified by optokinetic nystagmus frequency (OKNf) and gain (OKNg). RESULTS: Seated with no target, VV participants had higher OKNf than controls (37 ± 9vs.24± 9 peaks/sec; P<0.05). In Romberg stance with no target, they had higher OKNf than controls (41 ± 9vs.28± 10 peaks/sec; P<0.05).
