DESIGN: Prospective observational case series. METHODS: This study enrolled normal eyes with best corrected visual acuity ≥ 20/20, refractive error < 3.00D, and without visible retinal pathologic changes under a slit lamp-based condensing lens. The far peripheral retina was detected by UWFA. Ciliary body thickness (CBT) at 3 mm (CBT1) and 2 mm (CBT2) posterior to the scleral spur was measured by ultrasound biomicroscopy.
PURPOSE: To characterize the appearance of the far peripheral retina of normal eyes using ultra-widefield fluorescein angiography (UWFA).
DESIGN: Prospective observational case series. METHODS: This study enrolled normal eyes with best corrected visual acuity ≥ 20/20, refractive error < 3.00D, and without visible retinal pathologic changes under a slit lamp-based condensing lens. Demographic and clinical data such as age, sex, and reasons for undergoing FA were collected. The far peripheral retina was detected by UWFA. The fundal fields obtained using the Heidelberg ultra-widefield lens in a single shot and in montage images were compared with those acquired using the Heidelberg conventional 55° lens. The signs at the peripheral retina detected by UWFA were described and grouped. Ciliary body thickness (CBT) at 3 mm (CBT1) and 2 mm (CBT2) posterior to the scleral spur was measured by ultrasound biomicroscopy.

This study is designed to collect in-tissue OCT scans on the Optos P200TE on normal healthy eyes to develop a EU reference database
The aim of this study is to quantify and compare the foveal avascular zone (FAZ), the parafoveal and foveal vessel density of superficial (SCP) and deep capillary plexus (DCP) and retinal ...
The OCT used in this trial offers the advantage of both a non-contact method and a very high axial resolution. Determined parameters with the highest potential of diagnostic discrimination...
After focusing many years only on intraocular pressure (IOP) as the primary risk factor, recently the impact of ocular blood flow is getting more consideration for the pathophysiology of g...
The purpose of the study is to analyze the sensation to eye drops containing menthol in people with healthy eyes and in people with dry eyes. This study also examines the temperature of yo...
Optical coherence tomography is commonly used to measure the retinal nerve fibre layer thickness in both normal and diseased eyes; however, variation among normal eyes is common and may limit the usef...
This study aims to describe the variation and characteristics of vessel density (VD) of the macula and optic disc in the normal eyes of children.
To investigate the difference in longitudinal change of ß-zone parapapillary atrophy (PPA) between eyes with primary open-angle glaucoma (POAG) and normal eyes.
Choriocapillaris (CC) imaging of normal eyes with swept-source optical coherence tomography SS-OCTA was performed, and the percentage of CC flow deficits (FD%) and the average area of CC flow deficits...
To evaluate the IOP values obtained from normal canine eyes, by means of the TonoVet Plus (TVP) and TonoPen Avia (TPA), and compare them to an established tonometer, the TonoVet (TV).
Gases that irritate the eyes, throat, or skin. Severe lacrimation develops upon irritation of the eyes.
Partial or complete loss of vision in one half of the visual field(s) of one or both eyes. Subtypes include altitudinal hemianopsia, characterized by a visual defect above or below the horizontal meridian of the visual field. Homonymous hemianopsia refers to a visual defect that affects both eyes equally, and occurs either to the left or right of the midline of the visual field. Binasal hemianopsia consists of loss of vision in the nasal hemifields of both eyes. Bitemporal hemianopsia is the bilateral loss of vision in the temporal fields. Quadrantanopsia refers to loss of vision in one quarter of the visual field in one or both eyes.
Involuntary rhythmical movements of the eyes in the normal person. These can be naturally occurring as in end-position (end-point, end-stage, or deviational) nystagmus or induced by the optokinetic drum (NYSTAGMUS, OPTOKINETIC), caloric test, or a rotating chair.
A species of gram-negative, aerobic bacteria that is most frequently isolated from bovine eyes in cases of infectious keratoconjunctivitis (KERATOCONJUNCTIVITIS, INFECTIOUS), but also occurs in unaffected eyes and the nasal cavity of cattle.
A malformation of the nervous system caused by failure of the anterior neuropore to close. Infants are born with intact spinal cords, cerebellums, and brainstems, but lack formation of neural structures above this level. The skull is only partially formed but the eyes are usually normal. This condition may be associated with folate deficiency. Affected infants are only capable of primitive (brain stem) reflexes and usually do not survive for more than two weeks.

Ophthalmology is the branch of medicine that is devoted to the study and treatment of eye diseases. As well as mild visual defects correctable by lenses, ophthalmology is concerned with glaucoma, uveitis and other serious conditions affecting the eye, ...
Radiology is the branch of medicine that studies imaging of the body; X-ray (basic, angiography, barium swallows), ultrasound, MRI, CT and PET. These imaging techniques can be used to diagnose, but also to treat a range of conditions, by allowing visuali...
