New injectable agents are expanding the role of fillers in facial soft tissue augmentation. Radiance FN (fine needle) is a new injectable filler composed of calcium hydroxylapatite (CaHA) microspheres suspended in an aqueous gel carrier. CaHA has been used in various forms as a human implant material with an excellent record of biocompatibility.

Purpose: To study the efficacy of eyelid tissue removed during upper eyelid blepharoplasty as a filler graft to augment lips.
Methods: A prospective study involving 14 female patients who underwent lip enhancement with eyelid tissue. All patients underwent CO2 laser upper eyelid blepharoplasty and desired fuller lips.
The purpose of this study was to report the use of aerosolized fibrin glue in face-lift surgery. A prospective study was conducted of 48 patients undergoing face-lift surgery sequentially assigned into two groups. The first 24 patients underwent face lifts without glue and the next 24 patients with the use of aerosolized fibrin glue.

It has been suggested that this technology may be best suited for revision of failed DCR cases. The authors prospectively evaluated the efficacy of transcanalicular laser-assisted revision DCR (TCLARDCR).

Although fibrous dysplasia is benign, it may produce a mass effect along the course of the optic nerve, inducing visual disturbances. Optic canal decompression in patients without clinical signs of optic neuropathy is controversial.

Squamous cell carcinoma accounted for 24 of 648 (3.7%) malignant eyelid lesions submitted during the 10-year study period.

Methods: Color Doppler imaging was used to measure the peak systolic velocity and vascular resistance (pulsatility index) in the retrobulbar arteries of involved eyes and clinically healthy fellow eyes of patients with central retinal vein occlusion and in the control eyes of age- and sex-matched healthy volunteers.
Results: Average peak systolic velocity was significantly lower and average vascular resistance was significantly higher in the central retinal artery of involved eyes of patients with central retinal vein occlusion compared with clinically healthy fellow eyes and compared with control eyes.
Objectives: To determine quantitative and qualitative hemodynamic alterations within the ophthalmic, central retinal, and short posterior ciliary arteries in patients with giant cell arteritis (GCA) proved by biopsy specimen.
Design, Patients, And Setting: A consecutive case series of patients with GCA referred to an urban eye hospital who were evaluated with color Doppler imaging that was used to analyze orbital blood flow velocities and vascular resistance in 22 consecutive patients with GCA compared with age and sex-matched controls.
Results: Patients with GCA all demonstrated significantly reduced central retinal and short posterior ciliary arterial mean flow velocities as well as significantly increased vascular resistance compared with matched controls.

A 41-year-old white woman presented with a 1-month history of epiphora and a painless medial canthal mass on the left that was unresponsive to antibiotic treatment. Computerized tomography (CT) and magnetic resonance imaging (MRI) scans delineated a soft tissue mass with bony destruction originating in the area of the left lacrimal sac with extension into the maxillary and ethmoid sinuses and inferomedial orbit. Open biopsy of the mass revealed adenoid cystic carcinoma (ACC).

Combining B-scan ultrasonography and Doppler waveform analysis, CDI enables noninvasive serial examination of blood velocity and vascular resistance from the ophthalmic, short posterior, ciliary and central retinal arteries. This technology is being used to study the ophthalmic circulation of patients with primary open-angle or normotension glaucoma.

Methods: Color Doppler imaging was performed within 48 hours before surgery and within 48 hours after the procedure using a color Doppler unit with a 7.5-MHz phased linear transducer.
Purpose: The purposes of this study are to evaluate the retrobulbar circulation in progressive nonarteritic ischemic optic neuropathy (NAION) and to assess changes in blood flow after optic nerve sheath decompression (ONSD).
Methods: Twenty-five patients with progressive NAION were studied using color Doppler imaging (CDI) before and after ONSD. Blood flow velocities and vascular resistance were calculated for the ophthalmic artery, central retinal artery, and posterior ciliary arteries in each eye.
Purpose: This study describes hemodynamic characteristics of the ophthalmic, central retinal, and posterior ciliary arteries in 16 eyes of 11 patients with the ocular ischemic syndrome. Understanding the hemodynamic characteristics of the retrobulbar circulation may elucidate the natural history and pathophysiology of the ocular ischemic syndrome and perhaps form the basis for rational treatment of this condition.
Methods: Color Doppler imaging, a procedure that permits rapid noninvasive imaging of the ophthalmic, central retinal, and posterior ciliary arteries, was used to quantitate peak systolic blood flow velocities and vascular resistance (pulsatility index) within these vessels in study group eyes and in an age-matched control population.
Color Doppler imaging was used to evaluate a patient with gaze-induced amaurosis caused by an intraconal orbital mass. The time-velocity waveform demonstrated abnormally high vascular resistance in the central retinal artery of the affected eye in the primary position. Abduction of the affected eye resulted in transient visual loss with an unreactive pupil.

Color Doppler imaging (CDI) is a recent advance in ultrasonography that allows simultaneous two-dimensional imaging of structure and blood flow. Doppler information is superimposed in color over a conventional gray-scale ultrasound image. Using this technique we have examined 400 eyes.
View Article and Find Full Text PDFColor Doppler imaging was used to evaluate the hemodynamics of the ophthalmic vasculature in a case of complete internal carotid artery occlusion. This procedure, which allows rapid, noninvasive imaging, showed a partial ophthalmic artery obstruction with absent flow in the central retinal artery, central retinal vein, and nasal posterior ciliary arteries. Although altered perfusion of the retinal vessels may be evaluated clinically, assessment of blood flow in the ophthalmic and ciliary arteries previously could be evaluated only indirectly by intravenous fluorescein angiography.
