Diabetic retinopathy (DR) is one of the most common and specific complications of diabetes. Thus, intervention is required to lower the incidence and prevalence of sight-threatening retinopathy. The aim of this study was to investigate the prevalence and incidence of diabetic retinopathy in elderly diabetic patients receiving early diagnosis and proper treatment and to explore risk factors for ...

OBJECTIVE To investigate the ocular blood flow response to systemic nitric oxide synthase inhibition in patients with primary open-angle glaucoma. METHODS In 12 patients with glaucoma and 12 age-matched control subjects, subfoveal choroidal blood flow, optic nerve head blood flow, ocular fundus pulsation amplitude, intraocular pressure, and systemic hemodynamic parameters were measured at bas...

The role of Helicobacter pylori infection in the control of lower esophageal sphincter (LES) motility, especially the occurrence of transient LES relaxations (TLESRs), was studied in eight H. pylori-positive and eight H. pylori-negative healthy subjects. During endoscopy, biopsy specimens were taken from the cardia, fundus, and antrum for determinations of H. pylori status, gastritis, and proin...

Purpose: Non-arteritic anterior ischemic optic neuropathy (NA-AION) is typically a disorder of patients 50 years and older predisposed to the vascular and structural optic disc risk factors. We present an interesting case of sequential development of NA-AION in a 45-year-old patient with end-stage renal disease undergoing hemodialysis. Methods: Observational case report. Results: A 45-year-old ...

In all laser treatments at the fundus of the eye the temperature increase is unknown. In order to optimize the treatment modalities, a noninvasive online temperature determination is preferable. Method: Applying laser pulses to the fundus, thermoelastic stress waves are emitted based on the thermal expansion of the heated tissue, mainly the retinal pigment epithelium (RPE). The amplitude of the...

Glaucoma is one of the ocular eye diseases that can cause gradual vision loss and permanent blindness if it is not treated in the early stage. Current screening test such as intraocular pressure (IOP) assessment is not efficient since eye pressure is not the only symptom of glaucoma. The most suitable assessment of the glaucoma is by analyzing the health of the optic nerve head. In order to qua...

Method of Study Patients presenting with venous thrombosis of the retina were referred to a clinic specially instituted for the study of these conditions. Those attending the clinic initially were given a full ophthalmic examination, which included ophthalmoscopy, applanation tonometry, and ophthalmodynamometry. The following biochemical investigations were routinely carried out: blood sugar, b...

I I A new method to recover and display 3D fundus lobictkn ~ow"w*n shape, inner bottom shape of eyeball, from stereo fundus image pair is developed. For the fundus stereo images, a simple stereo technique does not work, because the fundus is observed through eye lens and a contact wide-angle enlarging lens. In this yf lvLq: method, utilizing the fact that fundus forms a part of sphere, we ident...
