In an attempt to expand the knowledge of this condition of unknown etiology, we present 3 cases of linear interstitial keratitis. Case series (3 cases are presented) and literature review. [ncbi.nlm.nih.gov]

• Localized Edema

  Stromal keratouveitis manifested by extensive stromal edema and deep neovascularization in acquired syphilis. 25.  Keratitis usually remains localized rather than becoming diffuse  Necrotizing inflammation of the posterior cornea may effloresce centrally [slideshare.net]

• Notched Incisors

  […] nose)  hard palate defect  swollen knees  saber shins  short maxillae  protruding mandible A frequently-found group of symptoms is Hutchinson's triad,  Hutchinson's teeth (notched incisors),  Keratitis  Deafness occurs in 63% of cases Treatment [slideshare.net]

• Corneal Opacity

  METHODS: Five eyes of five patients with congenital syphilitic interstitial keratitis who underwent keratoplasty for corneal opacities and corneal edema were studied. [ncbi.nlm.nih.gov]

  For the past few years, the parents noted increased corneal opacity. Examination revealed opacity of the anterior stroma with ghost vessels. This is thought to be interstitial keratitis secondary to herpertic keratitis. [sarawakeyecare.com]

  Some corneal opacity usually remains, causing mild to moderate vision impairment. Corneal opacification and other typical findings on slit-lamp examination Serologic testing to determine etiology The specific etiology must be determined. [msdmanuals.com]

• Foreign Body Sensation

  A 45-year-old woman with healed syphilitic interstitial keratitis presented with decreased vision, foreign-body sensation of the right eye, and bilateral conjunctival injection. [ncbi.nlm.nih.gov]

  Patients tend to be more symptomatic if the lesions are corneal and may present with tearing, irritation, photophobia or foreign body sensation. [clspectrum.com]

  Presentation - redness, pain, photophobia, foreign body sensation and reduced visual acuity. There will usually be an epithelial defect ± the presence of white cell infiltrate ± oedema. [patient.info]

• Conjunctival Injection

  A 45-year-old woman with healed syphilitic interstitial keratitis presented with decreased vision, foreign-body sensation of the right eye, and bilateral conjunctival injection. [ncbi.nlm.nih.gov]

  Ocular signs usually begin with sectoral conjunctival injection followed by a subepithelial, peripheral keratitis. The interstitial keratitis which subsequently develops is described as anterior stromal or superficial. [eyewiki.aao.org]

  Patients may have an anterior chamber reaction, fine keratic precipitates and conjunctival injection. In the chronic phase, the vessels regress leaving remnants (ghost vessels). [clspectrum.com]

  Regarding the ocular surface, syphilis can cause conjunctivitis, 6 episcleritis or scleritis. 7,8 Interstitial keratitis (See Figure 1), often associated with conjunctival injection and anterior chamber inflammation, is a well-recognized manifestation [reviewofophthalmology.com]

• Frontal Bossing

   blunted upper incisor teeth known as Hutchinson's teeth  inflammation of the cornea known as interstitial keratitis  deafness from auditory nerve disease  frontal bossing (prominence of the brow ridge)  saddle nose (collapse of the bony part of [slideshare.net]

The patient underwent a systemic workup for interstitial keratitis. All results including RPR and MHA-TP were negative except for Lyme antibody titer (enzyme-linked immunosorbent assay [ELISA]) 178 U/ml (normal, <159 U/ml). [ncbi.nlm.nih.gov]

Treatment & Management Treatment of interstitial keratitis depends on the specific underlying disorder. [emedicine.medscape.com]

Treatment The treatment should include topical treatment for keratitis and systemic treatment for syphilis. 1. Local treatment. Topical corticosteroid drops e.g., dexamethasone 0.1% drops every 2-3 hours. [ophthalmologylife.blogspot.com]

Treatment • Urgent evaluation is indicated because early treatment prevents permanent deafness & blindness. • Systemic & topical corticosteroids. 18. Thank You [slideshare.net]

Sometimes topical corticosteroids Keratitis may resolve with treatment of the underlying condition. Additional topical treatment with a corticosteroid, such as prednisolone 1% qid, is often advisable. An ophthalmologist should treat these patients. [msdmanuals.com]

The prognosis of this secondary glaucoma was very poor, although medical therapy was taken for the wide open angle type, and surgical therapy for the angle closure type. [ncbi.nlm.nih.gov]

The prognosis with early diagnosis and treatment is good There are different types of keratitis, which include: Amoebic Keratitis: It is often seen in those who wear contact lenses and is caused by Acanthamoeba, a free-living amoeba Fungal Keratitis caused [dovemed.com]

Prognosis Prognosis for interstitial keratitis is good if recognized and treated early before significant corneal scarring has occurred. [eyewiki.aao.org]

Outlook (Prognosis) Diagnosing and treating interstitial keratitis and its cause early can preserve the clear cornea and good vision. [ufhealth.org]

Linear interstitial keratitis is a rare clinical entity and its histopathologic etiology remains undetermined. [ncbi.nlm.nih.gov]

Bacterial etiologies: Syphilis, Lyme Disease, Tuberculosis, Leprosy, Brucellosis, Leptospirosis Viral etiologies: Herpesviridae - Herpes simplex, Herpes Zoster, Epstein- Barr. [eyewiki.aao.org]

Epidemiology Interstitial keratitis is generally seen in the context of syphilis and, less commonly, in the context of herpes and Cogan syndrome. [emedicine.medscape.com]

Abstract We studied four patients with the clinical entity of nonsyphilitic interstitial keratitis and vestibuloauditory symptoms to determine whether immunologic abnormalities play a role in its pathophysiology. [ncbi.nlm.nih.gov]

A discussion of the causes, pathophysiology, and treatment of interstitial keratitis is also undertaken. The differential diagnosis and appropriate laboratory tests for patients with interstitial keratitis is given. [morancore.utah.edu]

(GPA) Connective tissue diseases Rheumatoid arthritis Background Epidemiology Incidence – rare; ~250 cases reported (Singer, 2015) Age – young adults in 20s-30s A few cases in children and adults >50 years Sex – M:F, equal Ethnicity – none reported Pathophysiology [arupconsult.com]

Pathophysiology The pathophysiology of interstitial keratitis is unknown, but varies significantly by eitology.The majority of bacterial and parasitic IK is a result of direct invasion of the corneal stroma and the host's allergic/ immune reaction to [eyewiki.aao.org]

Pathophysiology By definition, IK is a nonsuppurative inflammation, which is characterized by cellular infiltration of the corneal stroma. In general, no primary involvement of the corneal epithelium or endothelium occurs. [odlarmed.com]

SYSTEMIC - high doses of penicillin to prevent further development of lesions - systemic steroids can be given in refractory cases. 15. [slideshare.net]

Prevention Prevention consists of avoiding the infection that causes interstitial keratitis. If you do get infected, get prompt and thorough treatment and follow-up. Images References Ginsberg SP. Corneal problems in systemic disease. [ufhealth.org]

Special attention is given to the prevention and treatment of these diseases found in developing countries as well as the latest findings about new antimicrobial agents, gram-negative infections and their management, and recommendations for immunization [books.google.de]
