Clinical imaging and high-resolution ultrasonography in melanocytoma management.

Purpose: To demonstrate the utility of high resolution 20 MHz ophthalmic ultrasound in serial follow-up of optic nerve head melanocytoma patients.

Methods: This study is a retrospective review of 30 patients with melanocytoma of the optic nerve head studied with echography. All patients were evaluated with standard ophthalmic A-scan and B-scan ultrasonography and 10 (33%) underwent high-resolution ultrasound.

Multiply scattered light tomography and confocal imaging: detecting neovascularization in age-related macular degeneration.

A novel technique, Multiply Scattered Light Tomography (MSLT), and confocal Infrared Imaging are used to provide diagnostic information using a comfortable, rapid, and noninvasive method. We investigated these techniques in detecting neovascularization in age-related macular degeneration. The MSLT used a Vertical Cavity Surface Emitting Laser (VCSEL) at 850 nm, while the confocal imaging technique used either the VCSEL or a 790 nm laser diode.

Scanning laser reflectometry of retinal and subretinal tissues.

Measurements of the human ocular fundus that make use of the light returning through the pupil are called reflectometry. Early reflectometry studies were limited by poor light return from the retina and strong reflections from the anterior surface of the eye. Artifacts produced misleading results in diseases like age-related macular degeneration.

Small incision cataract surgery and placement of posterior chamber intraocular lenses in patients with diabetic retinopathy.

Background And Objective: Diabetic patients undergoing cataract surgery have been demonstrated to have a guarded prognosis. Small incision cataract surgery has been postulated to cause fewer complications than other techniques of cataract extraction. We looked at small incision cataract surgery to see how diabetics fared.

Ultrasound-guided cryotherapy for retinal tears in patients with vitreous hemorrhage.

Background And Objective: The goal was to utilize ultrasound-guided cryotherapy as an immediate, low-risk, noninvasive, precise method of treating retinal tears obscured by vitreous hemorrhage.

Patients And Methods: Eleven patients with sudden onset of vitreous hemorrhage were referred for diagnosis and management. Ophthalmoscopy with scleral depression was unsuccessful at localizing peripheral retinal tears, and all of the patients were examined with ultrasound using the techniques of standardized echography.

HIV and banked fascia lata.

Banked irradiated fascia lata is used in many ophthalmic procedures. Along with its increased popularity has come concern over protection from the AIDS virus. Banked fascia lata is protected against the AIDS virus by donor selection, antibody testing and irradiation sterilization.
