PURPOSE: To demonstrate how the concept of hemidivisional corneal topographic astigmatism (hemiCorT) enables the planning of hemidivisional corneal treatments to reduce irregularity and overall astigmatism. METHODS: Whole-of-cornea corneal topographic astigmatism (CorT) is calculated from topography data derived from a corneal topographer or tomographer. The cornea is conceptually divided into 2 hemidivisions along the flat meridian of the CorT. For each hemidivision, hemiCorTs are calculated...

PURPOSE: The purpose of this study was to evaluate the shape of the anterior sclera by measuring the sagittal height and corneoscleral transition angles in the four cardinal and four oblique segments of the eye. MATERIALS AND METHODS: In this study, 78 normal eyes of 39 subjects were evaluated. The sagittal height, corneoscleral angle and scleral angle were measured at three chord lengths (10.0mm, 12.8mm and 15.0mm) in all eight segments of the anterior eye using optical coherence tomography (Zeiss Visante AS-OCT)...

PURPOSE: To establish whether average refractive overcorrection or undercorrection of corneal astigmatism based on the orientation (rule) of the astigmatism occurs if toric intraocular lenses (IOLs) are calculated on the basis of anterior corneal measurements in eyes requiring toric IOL cylinder power of 2.50 diopters (D) or greater. METHODS: One hundred thirteen consecutive eyes with anterior corneal keratometric astigmatism requiring IOL cylinder power of 2.50 D or greater underwent phacoemulsification with IOL powers calculated using anterior corneal curvature data alone...

In this chapter, we describe the visuotopy of the pulvinar subdivisions P1, P2, and P4. In all primates, P1 colocalizes with the chemoarchitecturally defined PI and a small portion of PL. The peripheral visual field is represented anteriorly in the medial portion of PI, while central vision is represented more posteriorly in the medial portion of PL. The vertical meridian representation is located on the lateral edge of P1, while the horizontal meridian is represented obliquely from the lateral to the medial extent of P1...

The oblique effect-poorer performance when contours are in oblique meridians-is here extended from the discrimination of line-orientation to the tilt illusion and to the detection and contextual induction of curvature. The distinction is made between a contour's susceptibility to contextual perturbation and its capacity to induce such perturbation, for which the oblique effect is only about one half. That the cardinal/oblique superiority is retained for the orientation of illusory borders and for the implicit orientation of shapes lacking explicit rectilinear delineation has implications for its neural substrate...

PURPOSE: To investigate the topographic relationship between parapapillary deep-layer microvasculature dropout (MvD) as assessed by optical coherence tomography (OCT) angiography (OCTA) and the juxtapapillary choroidal thickness (JPCT) in primary open-angle glaucoma (POAG). METHODS: A total of 194 eyes (138 POAG and 56 control eyes) having parapapillary atrophy (PPA) were imaged using the swept-source OCT and OCTA to examine the microstructure of PPA and measure the JPCT, and to determine the presence of the MvD...

PURPOSE: To investigate how macular ganglion cell-inner plexiform layer (GCIPL) and retinal nerve fibre layer (RNFL) thicknesses within the macula change with retinitis pigmentosa (RP) severity. METHODS: Spectral domain optical coherence tomography (SD-OCT) was used to examine 177 patients with RP and 177 normal controls. An optical coherence tomography (OCT) line scan was used to grade RP severity. Retinitis pigmentosa (RP) was categorized as more advanced if there was no identifiable inner segment ellipsoid (ISe) band (NISE) and as less advanced if an ISe band could be identified and peripheral loss of ISe was apparent (IISE)...

PURPOSE: To evaluate the intra-session repeatability of keratometric measurements obtained in healthy eyes with the Verion image-guided system (Alcon Laboratories Inc, Fort Worth, Texas, USA) as well as the interchangeability of such measurements with those obtained with an optical biometer (Aladdin, Topcon, Tokyo, Japan). METHODS: A total of 53 eyes of 53 patients (age 31-67 years) were enrolled in the study. All eyes received a comprehensive ophthalmologic examination including an analysis with the Verion image-guided and Aladdin systems...

Recent clinical trial studies have demonstrated that the effects of acupuncture on pain improvement are small and no difference between acupoints and non-points. Whether acupuncture needles must be inserted in specific points depends on whether acupoint specificity exists that is still not resolved, and is now urgent. Previous anatomical studies have demonstrated that acupoints exist higher number of nerve fibers/trunks, blood vessels, hair follicles, and sweat glands as well as density of the gap junction...

Temporomandibular disorders (TMD), recognized as the most common conditions of chronic orofacial pain, have a multifactorial etiology. Acupuncture can help to relieve the pain and discomfort associated with these conditions, because it can rebalance the energy (Qi) circulating in the meridians. The aim of the study was to verify the effectiveness of acupuncture in treating the pain; mouth opening limitation, and energy circulating in the meridians of patients with TMD of muscular or mixed origin. This was a controlled, randomized, double-blind clinical trial conducted at the Piracicaba Dental School (FOP/Unicamp), in Piracicaba SP, Brazil...

PURPOSE: Amyotrophic lateral sclerosis (ALS) is a chronic, fatal neurodegenerative disease which leads to progressive muscle atrophy and paralysis. In order to summarize the characteristics of Traditional Chinese Medicine compounds and their preparations in the prevention and treatment of ALS through analyzing the mechanism, action site, and symptoms according to effective clinical research. METHODS: We searched ALS, motor neuron disease, chemical drugs, herbal medicine, Chinese medicine, Traditional Chinese Medicine (TCM), and various combinations of these terms in databases including the PudMed, Springer, Ovid, Google, China National Knowledge Infrastructure, and Wanfang databases...

OBJECTIVE: To develop an animal model suitable for the study of acupoint sensitization in myocardial ischemia(MI) animals by observing changes of the mechanical withdrawal threshold (pain threshold, PT). METHODS: Twenty New Zea-land rabbits were randomly divided into control and model groups (n=10 in each group). The controllable MI model was set up by installing a balloon occluder at the left anterior descending branch of the left coronary artery. Air inflation of the balloon was given for 5 min/time, twice a day (4-hours' interval) for continuous 5 days (the first stage of MI), with one day's rest, then, another 5 days' air inflation was conducted again (2(nd) stage of MI)...

The ancient classic work Yellow Emperor's Inner Canon has abundant expositions about the relationship between the acupuncture needle manipulation and pulse diagnosis. However, the relevant imparting and inheritance situations are relatively weaker nowadays probably due to the rapid development of modern diagnosis-therapeutic techniques and some faults or careless omission in understanding classical medical works. Qi, a core concept of the abundant expositions in Inner Canon, has seldom been thoroughly interpreted about its connotations...

OBJECTIVE: To explore the regularity of distribution of press-sensitive acupoints on the body surface in tinnitus patients, so as to provide evidence for selecting suitable acupuncture points in the treatment of tinnitus. METHODS: Sixty-three cases of tinnitus patients (from 25 to 75 years in age) were recruited in the present study. The patient was asked to take a sitting, supine and prone position, successively, and the operator used the thumb to moderately press the subject's head, neck, back, four limbs below the knee- and elbow joints along the three Hand- and three Foot-yang and yin meridians...
