342 Possible Causes for Visual Acuity Decreased, Visual Field Constriction

  • Glaucoma

    After 2 months, choroidal swelling had completely resolved, best-corrected visual acuity was 20/50, and intraocular pressure was 11 mm Hg.[] All eyes had a constricted visual field RESULTS: The mean follow-up duration was 29 months (range 6 to 54) and 33 (97%) eyes were followed for more than 1 year.[] field.[]

  • Open-Angle Glaucoma

    His best-corrected visual acuity (BCVA) decreased gradually over 5 years.[] Typically, patients are only symptomatic in late disease, when they may become aware of constricted visual field or blurred vision.[] […] of peripheral field A temporal island of the visual field Intraocular pressure When determining the IOP of a patient using tonometry, certain variables must be taken into[]

  • Craniopharyngioma

    A 64-year-old female patient presented with headache and decreased visual acuity for the last four years, computed tomography (CT) and magnetic resonance imaging (MRI) revealed[] The authors present the case of a 12-year-old boy who developed progressive visual field constriction 11 years after gross-total resection of a solid and cystic craniopharyngioma[] We describe a 12-year-old boy addressed for suspicion of craniopharyngioma diagnosed by decreased visual acuity, bitemporal hemianopia and a CT scan showing a large hypodense[]

  • Retinitis Pigmentosa

    Macular edema may cause additional central visual acuity decrease. Cystoid macular edema (CME) is one of the few treatable causes of visual loss in RP.[] A 63-year-old man with a long history of nyctalopia, progressive visual field constriction, and a recent subacute decrease in visual acuity of the left eye presented for evaluation[] Removal of the cataracts may lessen glare and improve visual acuity. Decreased Visual Acuity A portion of RP patients, will experience a loss of central vision.[]

  • Retinitis

    As the visual field constricts, efforts are being explored for the use of visual field expanding glasses.[] Removal of the cataracts may lessen glare and improve visual acuity. Decreased Visual Acuity A portion of RP patients, will experience a loss of central vision.[] The visual acuity decrease was not statistically significant.[]

  • Idiopathic Intracranial Hypertension

    One patient had horizontal diplopia due to an acute sixth nerve palsy along with severe constriction of visual fields while the second patient had symptoms of blurred vision[] We report the case of a 14-year-old girl with sudden onset of decreased visual acuity, headache and menstrual irregularity.[] visual acuity.[]

  • Optic Disc Drusen

    We describe a case of an acute symptomatic and non-progressive visual field constriction in one eye of a 19-year-old female with optic disc drusen.[] Decreased visual acuity due to drusen occurred in only one eye due to subretinal neovascularization.[] Pigmented paravenous retinochoroidal atrophy is usually asymptomatic and seldom causes marked decrease in visual acuity or significant impairment of electrophysiologic functions[]

  • Refsum Disease

    visual acuity appear.[] There is typical night blindness and visual field constriction. Rod ERG responses are usually subnormal.[] In 1991, this 34 year old man from Egypt presented with progressive gait disorder and visual field constriction.[]

  • Peripheral Vasoproliferative Retinopathy

    Younger children are more likely to present with leukocoria and strabismus, while older children and adults are more likely to detect and report a decrease in visual acuity[] Other rare but possible adverse effects of PRP include visual field constriction (with implications for driving), night blindness, color vision changes, inadvertent laser[] Complications of panretinal photocoagulation (PRP) Constriction of visual field. Nocturnal diminution of vision. Burns affecting the fovea centralis.[]

  • Normal-Tension Glaucoma

    A detailed workup including neuroimaging may be indicated in patients with decreased central visual acuity ( 20/40), patients under 50 years of age, individuals with visual[] Field No deteclable visual field defect Mild generalized reduction in retinal sensitivity Mild constriction of isopter Nasal step to 20 degrees Paracentral scotomas Mild[] Glaucoma is detected through a comprehensive dilated eye exam that includes the following: Visual acuity test.[]
