Hip joint stress distribution changes depending on three-dimensional pelvic orientation: Finite-element analysis.

Background: Pelvis experiences changes in its orientation due to the alignment of the hip joint and spine, and its orientation might affect both joints. Pelvic tilt on the sagittal plane has been widely discussed; however, the pelvis is oriented also on the coronal and horizontal planes. This study aimed to examine how stress distribution on intact hip joint changes under the three-dimensional pelvic orientation.

Retinal sensitivity after resolution of the macular edema associated with retinal vein occlusion.

Purpose: To study the correlation of retinal sensitivity with both morphologic changes in the macula and status of retinal capillary perfusion, after resolution of the macular edema associated with retinal vein occlusion (RVO).

Methods: Retinal sensitivity in the macular area was examined with the Micro Perimeter 1 in 24 eyes after resolution of the macular edema associated with RVO. Using spectral-domain optical coherence tomography, 6 mm × 6 mm areas of macula were examined with 256 sequential horizontal scans.

Objective: To compare pathologic changes in photoreceptors in eyes with resolved central serous chorioretinopathy (CSC) seen on high-resolution images obtained by adaptive optics scanning laser ophthalmoscopy (AO SLO) with visual acuity (VA) and findings on spectral-domain optical coherence tomography (SD OCT).

Design: Observational case series.

Participants: Forty-five eyes of 38 patients with resolved CSC and 20 normal eyes of 20 volunteer subjects.

Relationship between retinal sensitivity and morphologic changes in eyes with confluent soft drusen.

Purpose: To examine the relationship between retinal sensitivity and morphologic changes in the macular area of eyes with confluent soft drusen.

Methods: We retrospectively reviewed the medical records of the 21 consecutive patients (22 eyes) who had confluent soft drusen in the macular area. Using spectral-domain optical coherence tomography, a 6 x 6-mm area of each macula was examined with 256 sequential horizontal scans.

Restoration of outer segments of foveal photoreceptors after resolution of central serous chorioretinopathy.

Purpose: To study morphologically and functionally the prognosis of damaged outer segments of the foveal photoreceptor layer in eyes with resolved central serous chorioretinopathy (CSC).

Methods: We studied retrospectively the medical records of 70 patients (74 eyes) with resolved CSC. Optical coherence tomography was used to detect the junctions between inner and outer segments of the photoreceptors (IS/OS) as a hallmark of the integrity of the outer photoreceptor layer.

Punctate hyperfluorescent spots associated with central serous chorioretinopathy as seen on indocyanine green angiography.

Purpose: The purpose of this study was to examine indocyanine green angiography of eyes with central serous chorioretinopathy (CSC).

Methods: We retrospectively studied the medical records of 39 patients (41 eyes) with active CSC who were <50 years of age. All patients had undergone fluorescein angiography and indocyanine green angiography using a confocal laser scanning system.

Macular polypoidal choroidal vasculopathy with a remote lesion.

Purpose: To report cases of the macular type of polypoidal choroidal vasculopathy with a remote lesion.

Methods: We report six patients (seven eyes) with polypoidal choroidal vasculopathy who had macular and remote lesions. These eyes were examined with angiography and tomography.

Central retinal sensitivity after intravitreal injection of bevacizumab for myopic choroidal neovascularization.

Purpose: To evaluate retinal sensitivity in the macular area after intravitreal injection of bevacizumab in eyes with myopic choroidal neovascularization (mCNV).

Purpose: To report the tomographic features of vascular lesions beneath the retinal pigment epithelium in eyes with polypoidal choroidal vasculopathy by using spectral-domain optical coherence tomography (SD-OCT).

Design: Retrospective observational case series.

Methods: Angiograms and images obtained using the prototype SD-OCT system were compared for 21 eyes of 21 patients with polypoidal choroidal vasculopathy to identify sub-retinal pigment epithelium abnormalities visible on three-dimensional and enhanced SD-OCT images.

Purpose: To examine retinal sensitivity in the macular area of eyes with resolved central serous chorioretinopathy (CSC).

Design: Retrospective chart review.

Methods: We studied retrospectively the medical records of 21 patients (21 eyes) with resolved CSC.

Purpose: To study the clinical characteristics of tears of the retinal pigment epithelium (RPE) in eyes with polypoidal choroidal vasculopathy (PCV).

Methods: The authors report eight eyes of eight patients with PCV that had tears of the RPE. These were examined with angiography and tomography.
