Ophthalmic artery velocimetry in normotensive and preeclamptic women with or without photophobia.

OBJECTIVE: To compare ophthalmic arterial velocimetry in normotensive and preeclamptic gravidas with and without photophobia. METHODS: Ophthalmic arteries were studied by color-flow Doppler ultrasonography in 118 normotensive pregnant women, 20 gravidas with preeclampsia and no visual symptoms, and 11 with preeclampsia, photophobia, and retinal edema. RESULTS: The ophthalmic arterial pulsatility index (PI) correlated negatively with gestational age (y = -0.01x + 1.84, r = -0.41, P<.01). Pulsatility index in preeclamptics with photophobia (0.71+/-0.17) was lowest among the three groups (P<.01) and was highest in normotensive pregnant women (1.41+/-0.21, P<.01). Mean velocity in normotensive pregnant women (0.19+/-0.05 m/second) was highest among the groups (P<.01) and was not significantly different in preeclamptic women with no visual symptoms (0.27+/-0.03 m/second) and with photophobia (0.30+/-0.02 m/second). CONCLUSION: Preeclamptic women, especially those with photophobia, have orbital vascular vasodilation or hyperperfusion, or both.

Photophobia and cortical visual impairment.

Photophobia, or intolerance of light, is not completely understood as a symptom. It has been divided into ocular and central types. This study shows that persistent, usually mild, photophobia occurs in about one-third of children with cortical visual impairment (CVI). When the CVI is congenital the photophobia is present from birth, and when it is acquired the sensitivity to light appears immediately after the brain insult. The intensity of photophobia tends to diminish with time and occasionally it may even disappear. The pathophysiology is unclear, as in all other neurological disorders associated with photophobia.

Pain, photophobia, and retinal and optic nerve function after phacoemulsification with intracameral lidocaine.

OBJECTIVE: To evaluate differences in pain, photophobia, retinal and optic nerve function in test eyes given intracameral lidocaine compared with control eyes given intracameral saline after phacoemulsification under topical anesthesia. DESIGN: Prospective paired-eye intervention study with random treatment allocation. PARTICIPANTS: Thirty eyes of 15 patients underwent cataract surgery in both eyes under topical anesthesia. INTERVENTION: The first eye of each patient was randomly assigned to either 0.5 ml preservative-free 2% intracameral lidocaine or 0.5 ml of intracameral sterile saline. Within 5 months, the second eye automatically received intracameral saline if the first eye received intracameral lidocaine or vice versa. MAIN OUTCOME MEASURES: The duration of surgery was recorded. Immediately after surgery, each patient was asked to evaluate the degree of pain and photophobia experienced during surgery using a nominal scale. In addition, in five patients, electroretinography (ERG) and visual evoked response (VER) were performed within 1 week before surgery, immediately after surgery, and 1 day after surgery. Amplitudes and latencies were calculated. RESULTS: There was no difference in the duration of surgery comparing test eyes given intracameral lidocaine with control eyes given sterile saline (P = 0.81). There was no significant difference in the level of pain reported when comparing test eyes given intracameral lidocaine with control eyes (P = 1.00). None of the patients reported any significant difference in photophobia between their two eyes (P = 1.00). When comparing ERG measurements, test eyes given intracameral lidocaine did not show any significant decrease in ERG amplitudes or prolonged latencies compared with control eyes. When comparing VER measurements, test eyes given intracameral lidocaine did not show any increase in P1 latencies compared with control eyes (P = 0.31). When evaluating all postoperative ERG results 1 day after surgery, there was a suggestion of improved cone function. CONCLUSIONS: Although intracameral lidocaine does not depress retinal or optic nerve function, the addition of intracameral lidocaine to topical anesthesia during phacoemulsification does not significantly reduce intraoperative pain or photophobia.

Effectiveness of topical diclofenac in relieving photophobia after pupil dilation.

PURPOSE: To test the effectiveness of topical diclofenac in relieving photophobia after pupil dilation. SETTING: Department of Ophthalmology, Newcastle General Hospital, Newcastle-upon-Tyne, United Kingdom. METHODS: Twenty healthy patients and volunteers from the outpatient ophthalmology clinic were enrolled in a prospective, double-blind, placebo-controlled comparison in which the patient's fellow eye served as a control. Photophobia after pupil dilation was tested subjectively using a visual analog scale and a neutralization scale at 30 minute intervals for 2 hours after instillation of topical diclofenac. RESULTS: Both tests show a statistically significant reduction in photophobia in the diclofenac-treated eyes at each time interval (P < or = .05). This difference was also considered clinically relevant. CONCLUSION: Topical diclofenac given at the time of pupil dilation significantly reduced photophobia. The mechanism of action is unknown and requires further evaluation.

Ocular findings in ichthyosis follicularis, atrichia, and photophobia syndrome.

Ichthyosis follicularis, atrichia, and photophobia (IFAP) are typical features of a rare neuroichthyosis termed IFAP syndrome. We demonstrate the ultrastructural findings of the eyes from a 33-year-old patient with IFAP syndrome. Clinically, eyebrows and eyelashes were absent from birth, and photophobia was noted at the age of 1 year. The globes measured 28 and 29 mm, respectively, and both eyes showed a posterior staphyloma. Histopathologically, bilateral centrally located subepithelial avascular corneal scarring with secondary corneal amyloid deposition was found. In addition to already described ocular abnormalities in IFAP syndrome we demonstrate ultrastructural anomalies of desmosomes and tonofilaments in corneal epithelium; defects of basement membrane, Bowman layer, and anchoring fibrils; secondary corneal amyloid deposition; and keratocyte degeneration. A defective tear film, recurrent atopic keratoconjunctival inflammations, or a primary anomaly of corneal epithelial adhesion are potential causes for the corneal defects. Photophobia is most likely due to corneal abnormalities.

Child with manifestations of dermotrichic syndrome and ichthyosis follicularis-alopecia-photophobia (IFAP) syndrome.

We report on a boy with short stature, mental retardation, seizures, follicular ichthyosis, generalized alopecia, hypohydrosis, enamel dysplasia, photophobia, congenital aganglionic megacolon, inguinal hernia, vertebral, renal and other anomalies, and a normal chromosome constitution. The clinical findings include all the features that dermotrichic and ichthyosis follicularis-alopecia-photophobia (IFAP) syndrome have in common and in addition those that characterize IFAP syndrome (photophobia, recurrent respiratory infections, etc.), those that are present only in dermotrichic syndrome (nail anomalies, hypohydrosis, megacolon, vertebral defects, etc.) and additional ones (enamel dysplasia, renal anomalies, inguinal hernia, etc.). Two maternal uncles were referred as being affected by alopecia and ichthyosis suggesting X-linked recessive transmission. Various hypotheses concerning the relationship between the 2 syndromes and the present case are discussed.

Incidence of photophobia in peripheral and sector iridectomy.

Fifth patients had bilateral intracapsular cataract extractions with a peripheral iridectomy in one eye and a sector iridectomy in the opposite eye. There was no difference in photophobia between the two eyes in 78% of patients. Twelve percent of the patients had greater photophobia in the eye with the peripheral iridectomy, and 10% had greater photophobia in the eye with the sector iridectomy.

Ichthyosis follicularis with alopecia and photophobia in a mother and daughter.

A mother and daughter having ichthyosis follicularis with alopecia and photophobia (IFAP) are reported, with histopathological and electron microscopic findings. We have followed the clinical course of the mother for 26 years since she was 5 years old, and the daughter since birth. They have had almost all the classical and some of the minor symptoms of IFAP, including severe photophobia, extensive non-inflammatory follicular hyperkeratosis, generalized non-scarring alopecia, hyperkeratosis of the extensor aspect of the four extremities, nail deformity and recurrent cheilitis. In addition, their facial appearance greatly resembles that of previously reported patients. A consistent feature in the mother was florid keratotic inflammatory eruptions on the genital region during each of her pregnancies, which rapidly improved after the delivery. Skin biopsy of the genital lesion showed marked acanthosis with dyskeratosis and spongiotic changes. The electron microscopic examination of diseased skin showed damaged desmosomes with spongiosis. No obvious changes were found in normal appearing skin.

Ichthyosis follicularis, alopecia, and photophobia (IFAP) syndrome: clinical and neuropathological observations in a 33-year-old man.

The syndrome of ichthyosis follicularis, alopecia, and photophobia (IFAP) is an uncommon neuroichthyosis described in only 10 males so far. We report on a man with congenital ichthyosis and alopecia with apparently normal development in early infancy. Photophobia and generalized myoclonicastatic seizures began during or after the first year of age and were associated with progressive impairment of motor skills and mental abilities. He died at 33 years of age. Neuropathological findings showed an unusual deformation of the temporal lobes and olivocerebellar atrophy. Cytogenetic and molecular studies did not uncover deletions in either Xp22.2 to 3 or in Xq27.3 to qter.

Linear lesions reflecting lyonization in women heterozygous for IFAP syndrome (ichthyosis follicularis with atrichia and photophobia).

A diagnosis of IFAP (ichthyosis follicularis with atrichia and photophobia) syndrome was established in a 1-year-old boy with congenital hairlessness, generalized ichthyotic skin changes with follicular hyperkeratoses, and photophobia. IFAP syndrome is considered to be an X-linked recessive trait. The phenotype present in female carriers has so far not been delineated. A 2-year-old sister had atrophoderma and ichthyotic skin lesions arranged in a linear pattern and a large noncicatrical bald patch on her scalp. Similarly, the mother had linear lesions of scaling and atrophy as well as circumscribed hairless areas involving the scalp, the axillary region, and the lower legs. Sweat testing by means of iodine starch-reaction visualized hypohidrotic linear lesions corresponding to the areas of hyperkeratosis and atrophy. In both mother and daughter the lesions followed the lines of Blaschko, whereas the boy was diffusely affected. Family history showed that the boy's maternal uncle who had died at age 1 year was likewise affected with the same disorder. Moreover, the maternal grandmother had reportedly bald patches on her scalp and very dry skin. This is the first report to document linear skin lesions visualizing lyonization in women heterozygous for IFAP syndrome.

Quantitative evaluation of photophobia and phonophobia in cluster headache.

In order to evaluate photophobia and phonophobia in cluster headache (CH), light and sound-induced discomfort and pain thresholds were measured quantitatively in 50 patients and 50 sex-matched and age-matched headache-free controls. During bout (i.e., during the active period with attacks), CH patients were more sensitive to light and sound than controls (p < 0.001). Outside bout they did not differ significantly from controls except for binaural stimulation. Patients were more photophobic and phonophobic during bout than in the remission period (p < or = 0.05). However, for those tested during bout, the sensitivity to light and sound was not related to the presence of pain during test, usual pain intensity, or pain laterality. In response to a questionnaire about their sensitivity, a significantly higher proportion of patients considered themselves sensitive during bout than outside (91% vs 46% for light [chi 2 = 5.9, p < 0.05] and 89% vs 49% for sound [chi 2 = 4.7, p < 0.05]). These results indicate that photophobia and phonophobia are important accompanying phenomena of cluster bouts.

Photophobia and phonophobia in tension-type and cervicogenic headache.

Light and sound-induced discomfort and pain thresholds were measured in 26 patients with cervicogenic headache, in 40 patients with tension-type headache, and in 100 headache-free controls. Neither headache group was significantly different as to photophobia and phonophobia, but both were significantly more sensitive to light and sound than controls (p<0.0001), even when patients were tested in the headache-free period (p<0.05). Episodic and chronic tension-type headache had similar photo- and phonophobia thresholds (p> or =0.7). Tension-type headache patients were more photo- and phonophobic during headache than outside attack (p<0.05), but this was not true for cervicogenic headache (p> or =0.56). In cervicogenic headache patients, photophobia (p<0.05) but not phonophobia (p=0.28) was greater on the symptomatic side than on the non-symptomatic side.

Monocular photophobia.

Uniocular eye closure in bright daylight has been considered as evidence of a binocular vision anomaly. Two groups of patients with various binocular vision anomalies were studied and compared. The control group did not manifest uniocular or binocular photophobia while the experimental group admitted frequent eye closure. The variables studied included anisometropia, refractive error, suppression, amblyopia, heterophoria and strabismus. No relations were observed between academic achievement and anomalies of binocular vision utilizing three analytical methods. Monocular photophobia was not associated with anomalous binocular vision.

Binocularity and photophobia in intermittent exotropia.

The relationship between photophobia and binocular function in intermittent exotropia was examined in 42 subjects (21 patients and 21 controls). In all subjects fusional amplitude and strength of binocular sensory status were tested before and during exposure to bright light. An explanation of photophobia in intermittent exotropia was suggested as impairment in binocular cooperation, since the indicators of binocular function were significantly altered in the patients, particularly during light exposure.

Photophobia and lithium.

CLINICAL PICTURE: We report the case of a 45 year old woman who developed photophobia after 6 months on lithium at non-toxic levels. TREATMENT AND OUTCOME: Lithium was reintroduced twice and on both occasions this side-effect reoccurred within days. CONCLUSIONS: Photophobia has only been described previously as a symptom of lithium intoxication.

Photophobia, epiphora, and torticollis: a masquerade syndrome.

Three young children presented with photophobia, epiphora, and torticollis as the initial manifestation of a posterior fossa tumor. In each case there was a delay in treatment due to the presumptive diagnosis of a local ocular inflammatory condition. We recommend that children with unexplained photophobia, epiphora, and torticollis undergo an imaging technique to evaluate the posterior fossa.

Ichthyosis follicularis with alopecia and photophobia.

We treated two unrelated boys with ichthyosis follicularis, a rare skin disorder characterized by extensive noninflammatory spiny follicular hyperkeratoses, severe photophobia, and generalized noncicatricial alopecia. This disorder must be differentiated from keratosis follicularis spinulosa decalvans; ulerythema ophryogenes; keratosis pilaris rubra atrophicans faciei; atrichia with papular lesions; atrophodermia vermiculata; and keratitis, ichthyosis, and deafness syndrome, all of which share some clinical features. Ichthyosis follicularis with alopecia and photophobia appears to be a familial disorder, but too few cases have been reported to establish the exact mode of inheritance.

A new treatment for photophobia in posttraumatic aniridia: a case report.

PURPOSE: Using staining pigments with which we had gained experience in dermatography (medical tattooing) treatments of leucoma corneae, a new approach was developed to create an artificial iris-like staining at the mid-stromal level of the cornea to treat photophobia in a patient with posttraumatic aniridia. METHODS: After a central 4-mm half-depth trephination, a lamellar dissection of the corneal stroma toward the limbus was performed. A combination of colored pigments was introduced into this midstromal space, until a light blue artificial iris (to match the contralateral eye) with adequate blocking of light was created. RESULTS: A stable artificial iris was created in the mid-stromal level of the cornea. CONCLUSION: Dermatography pigments are stable in the corneal stroma and are useful to treat photophobia in aniridia following trauma.
