Glaucoma is a chronic eye disease that leads to vision loss. Since it cannot be cured, detecting the disease in time is important. The tests which are done to detect Glaucoma using intraocular pressure (IOP) are not sensitive enough for population based glaucoma screening. The assessment of Optic nerve head damage in retinal fundus images is both more promising and superior. In this paper the o...

Scleral indentation is widely used to examine the peripheral fundus, however it can increase the intraocular pressure (IOP) to high levels which can then affect retinal function. We evaluated the effects of scleral indentation on the macular function electrophysiologically. Intraoperative focal macular electroretinograms (iFMERGs) were recorded with and without controlling the IOP in 7 eyes. Wi...

In all fundus laser treatments of the eye, the temperature increase is not exactly known. In order to optimize treatments, an online temperature determination is preferable. We investigated a noninvasive optoacoustic method to monitor the fundus temperature during pulsed laser irradiation. When laser pulses are applied to the fundus, thermoelastic pressure waves are emitted, due to thermal expa...

purpose : to report a rare case of a patient with hypoparathyroidism presenting with bilateral disc swelling and near mature cataract as her first clinical manifestation case report : a 23-year-old woman presented with complaint of worsening vision since one year ago and a history of refractory seizures and headache for several years, being under treatment with lamotrigine 50 mg/daily. slit-lam...

PURPOSE To develop a noninvasive method for the investigation of choroidal blood flow (ChBF) and its regulation in the foveal region of the human ocular fundus. METHODS Measurement of ChBF was based on the technique of laser Doppler flowmetry (LDF). Sixteen normal subjects (age range, 20 to 64 years), with normal eye examination results, were asked to fixate on a diode laser beam (wavelength ...

A retrospective 5-year study examined the relationship between blood pressure and the severity and progression of mild background retinopathy in 48 patients with non-insulin-dependent diabetes and 38 with insulin-dependent diabetes who did not receive treatment in either eye for at least 3 years from their initial visit. All patients had annual medical and ophthalmic examinations including fund...

aim: to report a patient with fundus flavimaculatus or macular dystrophy with flecks, who came to medical attention due to deteriorated vision in one eye and combined hamartoma of the retina and retinal pigment epithelium. case presentation: a 26 year old lady was referred with history of progressive decreased vision in both eyes since childhood with recently deteriorated vision in her right ey...

OUR investigations assumed first that the difference of pressure between the arterial and venous parts of the capillary system acts as circulatory motor, further, that spontaneous venous pulsation of the fundus of the eye is a sign of a pressure prevailing within the central retinal vein lower than the intra-ocular tension. One hundred cases were examined: fifty of them showing spontaneous puls...

To determine the influence of onchocercal eye disease on the intraocular pressure of the Yanomami Tribe Aratha-ú of Roraima State, Brazil, considered endemic for onchocerciasis, a total of 86 patients were submitted to an ophthalmologic exam that included external examination, slit lamp examination, intraocular pressure measurement, and a fundus ophthalmoscope examination. A high prevalence of ...
