Evaluation of radial optic neurotomy for central retinal vein occlusion by indocyanine green videoangiography and image analysis.

Purpose: To evaluate the effects of radial optic neurotomy (RON) on retinal circulation in patients with central retinal vein occlusion (CRVO) by indocyanine green (ICG) videoangiography and a computer-assisted image analysis.

Design: An interventional case series.

Methods: RON was performed in 15 eyes of 15 patients with CRVO.

Time-frequency analysis of electronystagmogram signals in patients with congenital nystagmus.

Purpose: To evaluate the usefulness of the short-time Fourier transform (STFT) in the analysis of temporal congenital nystagmus characteristics.

Methods: We carried out an observational case series in patients with congenital nystagmus. An electronystagmogram (ENG) recording was performed for 300 s in 13 consecutive subjects with congenital nystagmus (age: 7-68 years).

Evaluation of arteriovenous crossing sheathotomy for branch retinal vein occlusion by fluorescein videoangiography and image analysis.

Purpose: We quantitatively evaluated the effects of arteriovenous (A/V) crossing sheathotomy on retinal circulation in patients with branch retinal vein occlusion (BRVO) accompanied by macular edema.

Design: Interventional case series.

Methods: In 18 consecutive patients (18 eyes) with BRVO accompanied by macular edema who underwent A/V crossing sheathotomy between August 1999 and April 2002, changes in retinal circulation after the surgery were evaluated by fluorescein videoangiography with a scanning laser ophthalmoscope and by image analysis using dye dilution technique.

Evaluation of the dynamics of choroidal circulation in experimental acute hypertensionusing indocyanine green-stained leukocytes.

Purpose: To evaluate the dynamics of choroidal circulation in experimental acute hypertension, using the indocyanine green leukocyte angiography (ILA) method, which the authors have developed for the evaluation of leukocyte dynamics in choroidal circulation.

Methods: Japan White rabbits were used in the present study. Leukocytes were collected by centrifugal separation of the autologous blood, and were stained with indocyanine green (ICG) dye.

Trehalose eye drops in the treatment of dry eye syndrome.

Objective: Trehalose can protect human corneal epithelial cells in culture from death from desiccation. This study was designed to test the efficacy and safety of trehalose eyedrops in the treatment of moderate to severe dry eye syndrome.

Design: A randomized, double-masked, dose-ranging, fellow eye-controlled clinical trial.

Risk factors for diabetic choroidopathy in patients with diabetic retinopathy.

Purpose: To identify risk factors for diabetic choroidopathy in patients with type 2 diabetes.

Methods: Forty-five consecutive patients with diabetic retinopathy underwent simultaneous indocyanine green angiography (ICG) and fluorescein angiography using a double detector and confocal scanning laser ophthalmoscopy in both eyes. Choroidal vascular abnormalities were evaluated by comparing the angiographic findings derived from the two methods.
