220 Possible Causes for Keratitis, Transillumination of the Iris

  • Iris Atrophy

    Infrared transillumination stereophotography of normal iris. Can J Ophthalmol 1977 ; 12: 308 – 11 . Google Scholar Medline ISI 19.[journals.sagepub.com] MAIN OUTCOME MEASURES: Development of cataract during management of Acanthamoeba keratitis.[ncbi.nlm.nih.gov] Clinically the iris would show hypopigmentation without transillumination defects. B. Iris pigment epithelial atrophy in diabetes mellitus.[entokey.com]

  • Foreign Body in the Eye

    Examine closely for iris tears and transillumination defects, lens opacities, AC shallowing, and asymmetrically low IOP in the involved eye.[lifeinthefastlane.com] […] eye is broken, including broken bones Severe pain Chemical exposure to the eye Sensitivity to light without cause Glaucoma Recent history of corneal ulceration or herpetic keratitis[walgreens.com] They can be associated with follicular conjunctivitis and also punctate keratopathy and subepithelial keratitis. Conjunctival lesions have also been reported.[healio.com]

  • Uveitis

  • Anterior Uveitis

    (BADI) and bilateral acute transillumination of the iris (BAIT), the finding of corneal endothelial pigment precipitates is a useful clue to the differential diagnosis. 18,19[touchophthalmology.com] […] uveitis with fewer keratic precipitates that are brown in color and located inferiorly.[ncbi.nlm.nih.gov] One year later, the patient appeared with a few round and whitish keratic precipitates and elevated IOP in his left eye.[ncbi.nlm.nih.gov]

  • Herpes Zoster Ophthalmicus

    There was no associated iris atrophy, no anterior chamber activity, intraocular pressure was 26 mmHg, and fundal examination of the left eye showed a cupped disc (CD 0.9)[nature.com] Acute keratitis is one of the most common of these ocular complications associated with HZO.[ncbi.nlm.nih.gov] Later findings may include iris transillumination defects and poor pupil reactivity.[eyeworld.org]

  • Idiopathic anterior Uveitis

Anterior Uveitis – Diagnostic Techniques & Signs Hypopyon vs Hyphaema 18.[slideshare.net]

  • Granulomatous Iritis

    (BADI) and bilateral acute transillumination of the iris (BAIT), the finding of corneal endothelial pigment precipitates is a useful clue to the differential diagnosis. 18,19[touchophthalmology.com] Cornea Keratic precipitates (KPs) are found on the endothelium. KPs are clusters of white blood cells.[emedicine.medscape.com] Corneal sensation is a useful test along with careful inspection of the iris for subtle transillumination defects, which may suggest underlying herpetic disease.[ophthalmologymanagement.com]

  • Fuchs' Heterochromic Iridocyclitis

    Markers of severe disease and a more guarded post-operative prognosis included severe iris atrophy with transillumination defects, glaucoma, and iris vasculature abnormalities[eyewiki.aao.org] She had a tripod dendritic pattern of keratic precipitates by confocal microscopy in the left eye with a stippled pattern of keratic precipitates in both eyes.[ncbi.nlm.nih.gov] It is diagnosed by attacks of this triad and the presence of iris transillumination corresponding to the rubbing site. The diagnosis is easiest during the attack.[intechopen.com]

  • Autosomal Dominant Keratitis

    The pupil size may be normal, but there may be loss of the iris surface architecture or the presence of iris transillumination. [1] [3] [16] Other iris changes include partial[eyewiki.aao.org] Diagnosis - Keratitis- hereditary * Home Eye Tests * Home Vision Tests Prognosis - Keratitis- hereditary Not supplied. Treatment - Keratitis- hereditary Not supplied.[checkorphan.org] Fifteen affected members, nine female and six male, of a four-generation family with hereditary keratitis.[ncbi.nlm.nih.gov]

  • Secondary Glaucoma

    This was evidenced by characteristic transillumination defects in the iris. 3 In 1992, researchers suggested that posterior bowing of the peripheral iris was caused by reverse[reviewofoptometry.com] To describe the association of acanthamoeba keratitis and glaucoma, to establish an incidence of glaucoma in patients with acanthamoeba keratitis, to discuss treatment options[ncbi.nlm.nih.gov] .  Gonioscopy – pigment accumulation along the Schwalbe’s line especially inferiorly (Sampaolesi’s line)  Iris transillumination – radial slit – like transillumination defects[slideshare.net]
