Ophthalmia Nodosa


Presentation

  • To present the diagnostic and therapeutic challenges of ophthalmia nodosa secondary to tarantula hairs.[ncbi.nlm.nih.gov]
  • 1 Images in ophthalmia nodosa: an unusual presentation of red eye. ( 29523620 ) 2018 2 Unique presentation of Ophthalmia Nodosa in an adult male patient with a novel management approach. ( 27843192 ) Shankar S....Sati A. 2016 3 A Hairy Affair: Ophthalmia[malacards.org]
Cat Scratch
  • We present a case of ophthalmia nodosa and Parinaud's oculoglandular syndrome in a patient scratched by a cat six and a half months previously and who gave a positive result to an antigen test for cat scratch disease.[ncbi.nlm.nih.gov]
  • . • causes  tularaemia, cat-scratch disease, tuberculosis, syphilis and lymphogranuloma venereum 185.[slideshare.net]
Physician
  • Please DO NOT STOP MEDICATIONS without first consulting a physician since doing so could be hazardous to your health.[ehealthme.com]
  • Due to recent lay press articles that promote tarantulas as pets suitable for children, parents and physicians must be aware of the possible dangers of these animals. REFERENCES 1. Along came some spiders. Wisconsin State Journal.[healio.com]
Hypertension
  • Keywords Food Allergy Macular Edema Ocular Hypertension Cystoid Macular Edema Intraocular Inflammation These keywords were added by machine and not by the authors.[link.springer.com]
Formication
  • It has been demonstrated by Karsten that the canal of the hairs carries formic acid[jamanetwork.com]
Chancre
  • 71 %) Cicatricial Pemphigoid (71 %) ( Benign Mucosal Pemphigoid, Benign Mucous Membrane Pemphigoid, Ocular Pemphigus, Scarring Pemphigoid,) Primary Inoculation Tuberculosis (71 %) ( Cutaneous Primary Complex, Primary Tuberculous Complex, Tuberculous Chancre[gulfdoctor.net]
Blepharospasm
  • So a high degree of suspicion is a must in a case with unilateral congestion, blepharospasm, multiple corneal abrasions, or nodular reaction involving conjunctiva. A careful repeated evaluation for detection of caterpillar setae becomes essential.[docksci.com]
  • On the left side the lids were oedematous and she had photophobia, lacrimation and blepharospasm in addition to pricking sensation.[ijo.in]
Retinal Lesion
  • Fundoscopy showed an area of inactive chorio-retinal lesion in the peripheral retina, with no evidence of vitritis. He was started on topical steroid treatment and responded well. Treatment is continuing. He remained completely symptom-free.[nature.com]
Stroke
  • The follicle was ruptured with the forceps and its base gently stroked. This resulted in a caterpillar hair popping out and this was pulled out with fine forceps.[ijo.in]

Treatment

  • Some authors advocate conservative treatment, as steroids can taper the inflammation despite the intracorneal retention of the hairs.6 Disappearance of the engulfed hairs by 10 months after a 3-month treatment with steroids has been reported.3 Others,[healio.com]
  • Treatment included topical steroids, cycloplegia, and removal of hairs with forceps. More than one sitting was required in 17 eyes (62.9%) due to reactional inflammation, precluding visualization of all the hairs.[ncbi.nlm.nih.gov]
  • Also described are systemic side effects of ophthalmologic drugs, treatment of chemical burns of the eyes, and testing methods and species specificity for toxic effects on the eyes.[books.google.de]

Prognosis

  • References Prognosis The prognosis is generally excellent. Occasional case reports of death from erucism exist, but death is very rare following stings by most species.[misc.medscape.com]

Etiology

  • Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology.[icd10coded.com]
  • BASED ON ETIOLOGY CONJUNCTIVITIS INFECTIOUS NON INFECTIOUS 34.[slideshare.net]

Epidemiology

  • References Epidemiology Frequency United States Although no accurate information is available, epidemics of erucism and lepidopterism have been reported.[misc.medscape.com]

Pathophysiology

  • References Pathophysiology Human disease from caterpillars or moths usually arises from direct contact, exposure to substances or animals that have been infested with caterpillars or their webs, or contact with airborne caterpillar debris.[misc.medscape.com]

Prevention

  • The information presented here is not intended to diagnose, treat, cure or prevent any disease. Read disclaimer.[gulfdoctor.net]
  • It is essential to recognize and treat this entity at an early stage to prevent the intraocular migration of these caterpillar hairs. REFERENCES 1. Saemisch T. Ophthalmia nodosa. Graefe-Saemisch Handbuch der gesamten Augenheilkunde. 2nd ed.[healio.com]
  • He also holds the very prestigious Jules and Doris Stein Professorship from Research to Prevent Blindness.[ophth.wisc.edu]
  • This resulted in the prevention of migration of the hair on a three month followup.[ijo.in]
  • Children who keep tarantulas as pets should be instructed on safe handling to prevent the tarantula from adopting defence mechanisms and shedding their hairs.[nzma.org.nz]
