Photophobia is a symptom of abnormal intolerance to visual perception of light. As a medical symptom, photophobia is not a morbid fear or phobia, but an experience of discomfort or pain to the eyes due to light exposure or by presence of actual physical sensitivity of the eyes, though the term is sometimes additionally applied to abnormal or irrational fear of light such as heliophobia. The term photophobia comes from the Greek φῶς (phōs), meaning "light", and φόβος (phóbos), meaning "fear". Photophobia is a common symptom of visual snow. Patients may develop photophobia as a result of several different medical conditions, related to the eye or the nervous system. Photophobia can be caused by an increased response to light starting at any step in the visual system, such as: Too much light entering the eye. Too much light can enter the eye if it is damaged, such as with corneal abrasion and retinal damage, or if its pupil(s) is unable to normally constrict (seen with damage to the ...

This gene encodes a intramembrane zinc metalloprotease, which is essential in development. This protease functions in the signal protein activation involved in sterol control of transcription and the ER stress response. Mutations in this gene have been associated with ichthyosis follicularis with atrichia and photophobia (IFAP syndrome); IFAP syndrome has been quantitatively linked to a reduction in cholesterol homeostasis and ER stress response.

Some cancer treatments may cause problems with your eyes, such as conjunctivitis, cataracts, dry eyes, photophobia and watery eyes.. Conjunctivitis: This condition, also known as "pink eye", is caused by a viral or bacterial infection, or an allergic reaction. Chemotherapy drugs tend to suppress your immune system, making you more susceptible to infection.. Cataracts: Cataracts are a cloudy area in the lens of your eye that prevents light from passing through. They are painless, but do lead to a progressive loss of vision. Cataracts usually occur in one eye and wont spread to the other.. Dry eyes: Your eyes will feel dry if you are not producing enough tears, or if your tears are lacking an important chemical involved in lubricating your eyes.. Photophobia: Sensitivity to light is called photophobia. This condition causes pain in your eyes when you move from a dark space to a light one, such as going outside during the daytime.. Watery eyes: Some drugs cause you to produce too many tears, ...

Light sensitivity, also known as photophobia, is a condition in which bright light - either natural sunlight or artificial light - can cause significant discomfort, pain and intolerance. People that experience light sensitivity will find themselves needing to close their eyes or squint when exposed to light and often experience headaches and nausea as well. In mild cases, the discomfort accompanies exposure to bright lights or harsh sunlight, but in severe cases even a small amount of light can cause pain and discomfort. Photophobia is more common in individuals with light eyes. This is because the greater amounts of pigment in darker eyes help to protect the eye from the harsh rays of light. The darker pigment of the iris and choroid absorbs the light, rather than reflecting the light and causing internal reflection or glare experienced by those with lighter eyes. People with albinism, which is a total lack of eye pigment, also experience significant light sensitivity for this reason. Acute ...

Patients with cone or cone-rod dystrophy typically present with progressive loss in visual acuity, abnormal colour vision, photophobia and often nystagmus. • The fundus may initially appear normal, but abnormalities can include peripheral hypopigmentation and/or pigment clumping, disc pallor, bulls eye maculopathy or macular atrophy. • Cone system photopic ERGs are reduced and usually delayed in cone dystrophy with additional involvement of rod-dominated scotopic ERGs in cone-rod dystrophy. • Pattern ERGs are usually markedly reduced or undetectable. Leber congenital amaurosis. • Severe visual impairment and roving eye movements or nystagmus from birth or early infancy. • Fundi are typically normal at presentation, but disc pallor, vessel attenuation and pigmentary changes may follow. • The ERG is severely reduced or undetectable from early infancy, indicating severe photoreceptor dysfunction. Rod or S-cone monochromatism. • Poor vision, nystagmus, photophobia and abnormal colour ...
With a same luminous stimulation, the visual cortex is activated during migraine headaches and after headache relief by sumatriptan but not during attack-free intervals. Thus visual cortex excitability or responsiveness appears to be different during migraine attacks and attack-free intervals.. The absence of cortical activation during the attack-free interval is explained by the characteristics of the luminous stimulation (see Methods11,12). Also, cortical response to uniform luminance stimulus has been carefully studied in different conditions using fMRI. Only peripheral part of area V1 has been reported to be activated due to intraocular scattering of light in luminance flicker situation, but not with constant uniform luminance stimulus.14 In a previous PET study, the same luminous stimulations with higher intensities (600 and 1,800 Cd/m2) did not induce cortical activation in controls, which is in accordance with the habituation phenomenon, but activated visual cortex in migraineurs during ...
Phlyctenular keratoconjunctivitis, also known as phlyctenulosis, is an inflammatory syndrome caused by a delayed (aka type-IV) hypersensitivity reaction to one or more antigens. The triggering antigen is usually a bacterial protein (particularly from Staphylococcus aureus), but may also be a virus, fungus (particularly Candida albicans), or nematode. Irritation Discomfort or pain Foreign-body sensation Tearing Blepharospasm Photophobia Mucopurulent discharge (rarely) In cases where the cornea is affected, pain and photophobia are more likely, and corneal scarring can occur (potentially impairing vision). The syndrome is marked by the appearance of characteristic lesions, known as phlyctenules, on the cornea and/or conjunctiva. These usually manifest as small (1 - 3 or 1 - 4 mm) raised nodules, pinkish-white or yellow in color, which may ulcerate (or, more rarely, necrose) and are often surrounded by dilated blood vessels. Corneal lesions are usually triangular in shape, with the base at the ...

Bandage contact lenses (BCL) may help reduce pain and result in a less intense wound healing response following femtosecond laser in situ keratomileusis (FS-LASIK), according to a study in the Journal of Ophthalmology.. This prospective, randomized trial included 41 patients (82 eyes) with myopia and/or myopic astigmatism. After FS-LASIK surgery, patients were fitted with a BCL in one eye but not in the contralateral eye. The BCL was left in place overnight and removed the next morning. All eyes subsequently received standardized postoperative treatments. Investigators followed patients for six months and evaluated the subjects self-reported postoperative symptom scores for pain, photophobia, tearing and foreign-body sensation. At six months after surgery, researchers examined the corneal flap margin and adjacent regions and photographed them using slit-lamp biomicroscopy to subjectively evaluate the wound healing response.. The study reported postoperative pain and photophobia were milder in ...

Smartphones were used in an online Ecological Momentary Assessment (EMA) design to test prodromal functioning relative to the interictal state in migraine patients. effects were found for effort spent and stressors encountered. Exploratory (random effect) analysis revealed significant individual differences in the change scores in sensory sensitivity, pain/stiffness, fatigue and negative affect. It is concluded that the prodromal change in migraine - relative to interictal functioning - predominantly exists within the last 12 hours before attack onset. Individual diversity is large, however. Future research should zoom in to identify prodrome development within the 12 pre-attack hours as well as to isolate individual patterns. Intro Migraine produces episodes of severe headaches, typically unilateral, of the pulsating quality and associated with nausea and/or throwing up, phonophobia and photophobia [1], which last 4-72 hours and hamper regular daily activity [1] markedly. Evidence demonstrates ...

Glaucoma is a condition in which the normal fluid pressure inside the eyes (intraocular pressure, or IOP) slowly rises as a result of the fluid aqueous humor--which normally flows in and out of the eye--not being able to drain properly. Instead, the fluid collects and causes pressure damage to the optic nerve (a bundle of more than 1 million nerve fibers that connects the retina with the brain) and loss of vision. Glaucoma is classified according to the age of onset. Glaucoma that begins before the child is three years old is called infantile or congenital (present at birth) glaucoma. Glaucoma that occurs in a child is called childhood glaucoma. Signs and symptoms of glaucoma may include excessive tearing, light sensitivity (photophobia), closure of one or both eyes in the light, cloudy, enlarged cornea, one eye may be larger than the other, and vision loss. Treatment of glaucoma usually involves surgery. Without treatment, blindness may occur.. ...

Intra- and periocular parasitic infection is rarely reported in the dog. The aim of this study is to describe the ocular manifestations of 60 cases of canine Onchocercosis in Greece, the largest series of cases ever reported, and to suggest the most suitable and effective treatment of the disease.. Sixty animals included in this study, admitted to the Ophthalmology Unit, Clinic of Surgery, School of Veterinary Medicine, AUTH, between 1997 and 2003, having similar ocular manifestations. The male female ratio was 3:1. Thirty-seven animals had bilateral ocular manifestations while the rest of them had unilateral. The most common ophthalmic manifestations in all animals were mild to severe periorbital swelling, conjunctival congestion, exophthalmos, photophobia, lacrimation and subconjunctival periocular masses. Diagnosis was based on clinical and ophthalmologic examination while ultrasound and histopathology of small skin snips collected from the head or the abdominal region was not always helpful. ...
The following case illustrates a misstep in the diagnostic process.. At 1300 hours on a weekend afternoon, a 47-year-old female nurse with a past history of migraine headache was transported by ambulance to the emergency department of a community hospital. Her chief complaint was a headache of sudden onset without her usual preceding aura.. She noted visual disturbances, described as rainbows, which occurred simultaneously with the onset of the headache. The headache was diffuse, pounding in nature, and associated with mild photophobia, nausea, and multiple episodes of vomiting. The severity was described as being equal to her worst migraine. The ambulance report documented that the patient described her headache as "her worst ever." The presenting vital signs were normal. She was assessed by emergency physician A within 15 minutes of arrival. A detailed neurological examination including fundoscopy, assessment for meningeal signs, and motor function was normal. A review of her hospital chart ...
