Ultrasound biomicroscopic findings in aniridia.

Purpose: To describe the ultrasound biomicroscopic features of eyes with aniridia.

Design: Observational case series.

Methods: Nineteen eyes of 10 patients with aniridia (six males and four females) ranging in age from 3 months to 53 years (21.

High-frequency ultrasonographic imaging in suprachoroidal hemorrhage after filtering surgery.

A 64-year-old woman with glaucoma had suprachoroidal hemorrhage approximately 6 hours after trabeculectomy. High-frequency ultrasonography revealed high reflectivity in the inner space of a kissing choroidal detachment, which facilitated the differential diagnosis of suprachoroidal hemorrhage resulting from serous choroidal detachment. The ciliary process and iris were anteriorly displaced due to the ciliary detachment and forward pressure of the anterior vitreous.

Detection of CMV DNA in the aqueous humor of AIDS patients with CMV retinitis by AMPLICOR CMV test.

The present study was performed to detect the cytomegalovirus (CMV) DNA in the aqueous humor from the eyes of acquired immunodeficiency syndrome (AIDS) patients with CMV retinitis. Detection of CMV DNA in the aqueous humor in the eyes with active CMV retinitis was compared with detection of CMV DNA in inactive retinitis. CMV DNA in the aqueous humor was evaluated before and after treatment with intravitreal injection of ganciclovir.

Detection of CMV in plasma and aqueous humor specimens from AIDS patients with CMV retinitis using the amplicor CMV test.

A DNA hybridization test (the Amplicor CMV test) for CMV DNA was used to detect CMV DNA in paired plasma and aqueous humor specimens from 37 AIDS patients with ophthalmoscopically diagnosed CMV retinitis. CMV was detected in 25/37 (67.6%) plasma specimens and in 32/37 (86.

Thallium-201 SPECT of orbital tumors.

Thallium-201 ((201)Tl) SPECT is utilized as a diagnostic imaging tool for a variety of tumors, such as lung cancer, brain tumors, etc., but there is hardly any literature on this type of imaging in orbital lesions. We examined 22 patients with orbital lesions and unilateral exophthalmos to evaluate the usefulness of (201)Tl-SPECT in the diagnosis of orbital tumors.

Up-regulation of Hrk, a regulator of cell death, in retinal ganglion cells of axotomized rat retina.

Hrk, a regulator of cell death, belongs to the family of pro-apoptotic BH3-only proteins and is known to induce apoptosis in nerve tissue. We examined Hrk gene expression to clarify the role of BH3-only proteins in apoptosis of retinal ganglion cells (RGCs) after optic nerve transection in the adult rat. Reverse transcription-polymerase chain reaction showed that Hrk was up-regulated in retina from 12 h after axotomy, and continued to be elevated for 1 week.

Measurement of axial length of eyes with incomplete filling of silicone oil in the vitreous cavity using x ray computed tomography.

Aims: To establish a reliable method for measuring the axial length of the eye with incomplete filling of silicone oil in the vitreous cavity in order to determine the IOL power before executing combined cataract surgery and silicone oil removal.

Methods: 12 eyes of 12 patients undergoing combined cataract extraction and silicone oil removal between October 1998 and June 2000 were entered prospectively into this study. All eyes were examined using an x ray computed tomography (CT) scanner.
