The vestibular system participates in cardiovascular regulation during postural changes. In prior studies (Holmes MJ, Cotter LA, Arendt HE, Cas SP, and Yates BJ. Brain Res 938: 62-72, 2002, and Jian BJ, Cotter LA, Emanuel BA, Cass SP, and Yates BJ. J Appl Physiol 86: 1552-1560, 1999), transection of the vestibular nerves resulted in instability in blood(More)
We conducted 25-gauge (25G) transconjunctival vitrectomy to treat patients with various ocular diseases, and examined the possibility of expanding the indications for this system through combined use with 20G devices when needed. The records of 167 patients (169 eyes) who underwent vitrectomy in our hospital between April and June 2004 were studied.(More)
Neovascular membranes obtained from surgical excision of neovascularization for retinal angiomatous proliferation (RAP) were examined histopathologically in an attempt to elucidate the pathogenic mechanism of RAP. Nine eyes of eight patients (mean age, 79±6 years) who underwent neovascularization excision were studied. Three eyes had stage II with RPE(More)
PURPOSE To compare the intraocular fluid leakage rate between 25-gauge (25G) transconjunctival vitrectomy with scleral tunnels and standard 25G transconjunctival vitrectomy. DESIGN Single-center, retrospective, interventional case series. METHODS Transconjunctival vitrectomies were conducted by the use of only 25G instruments with peripheral vitrectomy.(More)
1. Changes in posture can affect the resting length of the diaphragm, which is corrected through increases in both diaphragm and abdominal muscle activity. Furthermore, postural alterations can diminish airway patency, which must be compensated for through increases in firing of particular upper airway muscles. 2. Recent evidence has shown that the(More)
Changes in posture can affect the resting length of respiratory muscles, requiring alterations in the activity of these muscles if ventilation is to be unaffected. Recent studies have shown that the vestibular system contributes to altering respiratory muscle activity during movement and changes in posture. Furthermore, anatomical studies have demonstrated(More)
PURPOSE To evaluate the efficacy of laser photocoagulation for polypoidal choroidal vasculopathy (PCV) involving the macula. METHODS The records of 38 patients (47 eyes) undergoing laser photocoagulation for PCV causing serosanguineous detachment involving the fovea were reviewed and the results were evaluated. Ten eyes underwent photocoagulation to(More)
Previous transneuronal tracing studies conducted in the ferret revealed that a large population of neurons that provides inputs to diaphragm and abdominal motoneurons is located in the ventral magnocellular portion of the medial medullary reticular formation. These observations raise the possibility that the neural substrate underlying respiratory(More)
We report the postoperative outcomes of surgical neovascularization excision in patients with retinal angiomatous proliferation (RAP). Nine eyes of eight patients with RAP who underwent surgical excision of neovascularization were studied. Surgical indications were as follows: RAP diagnosed by fluorescein and indocyanine green angiography, foveal or(More)
To describe a new 20-gauge transconjunctival vitrectomy procedure that we designed, to evaluate its usefulness, and to compare two different methods of use. The records of 431 patients (433 eyes) who underwent 20-gauge transconjunctival vitrectomy at the Surugadai Hospital of Nihon University between March 2003 and January 2004 were studied retrospectively.(More)
