Aim: To study Retinitis Pigmentosa as a cause of blindness in patients attending Regional Eye Hospital, Kurnool for blind certificate. Methods: A total 1020 all age groups to certificate during the period August 2020 2022 were included and examined which include visual acuity testing using Snellen chart, refraction, slit lamp biomicroscopy,intra ocular pressure measurement Goldmann Applanation ...

purpose: to present 3 rare cases of benign flecked retina syndrome. patients and finding: a 19-year-old female patient presented with fundus albipunctatus appearance in fundoscopy without night blindness and normal dark adaptation time on electeroretinography (erg). after 9 years of follow up, no change in visual acuity, erg, or other ophthalmologic examinations was seen. two members of her fam...

1. In order to discover whether the changes in reactivity are related to the primary cause of hypertension in spontaneously hypertensive rats (SHR) or are just an adaptation induced by the high arterial blood pressure we tested the contractile response of a visceral smooth muscle from such rats. 2. Longitudinal strips of the fundus from 20 week old male and female SHR and Wistar normotensive (...

The appearance of fluorescein in the fundus of albino and pigmented rabbits was documented using a wide-angle fundus camera. Serial photographs were taken during decrease of intraocular pressure from levels above systolic ophthalmic artery pressure. In all the albino rabbits, the fluorescein first appeared in the choroid and only later in the retinal vessels. Contrary to this, in all the pigmen...

Regular uterine contractions in normal labor are expulsive power to deliver the fetus. The intrauterine pressure changes were recorded and studied in the measurement of labor contractions of uterus, while external tocodynamometry is common in clinical fetal monitoring [1]. The duration of contraction was about 1 min and interval was also 1 min, and the peak intrauterine pressure was 30 to 50 mm...

Laparoscopic sleeve gastrectomy can be associated with significant morbidity. Dehiscence of the staple line and gastric leak are some severest complications. The aim this study was to compare three different methods suture in terms strength volume/pressure sleeved stomach. resected stomachs 20 patients subjected laparoscopic were evaluated for bursting after extraction from abdomen. specimens c...

Glaucoma is a pathological condition, progressive neurodegeneration of the optic nerve, which causes vision loss. The damage to the optic nerve occurs due to the increase in pressure within the eye. Glaucoma is evaluated by monitoring intra ocular pressure (IOP), visual field and the optic disc appearance (cup-to-disc ratio). Cup-to disc ratio (CDR) is normally a time invariant feature. Therefo...

purpose: to evaluate the agreement between a new method for quantitative analysis of fundus or angiographic images using photoshop software and clinical judgment. methods: four hundred eighteen fundus and angiographic images of diabetic patients were evaluated by three retina specialists and then by computer using photoshop 7.0 software. four variables were selected for comparison: amount of ha...

A decreased count of retinal photoreceptors all over the fundus and a loss of retinal pigment epithelium cells mainly in the parapapillary region have been reported to be associated with glaucoma. This study addressed the question whether this cell loss in the deep retinal layers may be connected with a change of the choroidal thickness in glaucomatous eyes. Histological sections of 12 eyes wit...

PURPOSE First aim of the study was to define normal shape and diameter of the internal auditory canal (IAC). In the second part the clinical relevance of IAC-enlargement was analyzed, considering also lesions of the subtle structures at the fundus of the internal auditory canal. MATERIALS AND METHODS 440 high resolution CT-scans of the temporal bone were used for retrospective analysis of the...
