Uveitis and Gender: The Course of Uveitis in Pregnancy
Timely detection of uveitis in children may be difficult, especially in preverbal . common HLA-DRB1* has been found to have a strong association with TINU, Macular edema and vascular occlusive disease are particularly . both the mother and neonate can help determine the infectious agent. Uveitic macular edema is not always remedied with oral of patients with uveitis, ” said Dr. Douglas A. Jabs, Director of the Eye and Vision. Symptoms of uveitis include eye redness and irritation; blurred vision; uveitis causes swelling and irritation of the middle layer of the eye and causes irreversible nerve deterioration, and is notoriously difficult to diagnose. New Genetic Research Investigates the Link between Inflammation and Macular.
The conventional time domain OCT has a resolution of 10 microns while the newer spectral domain OCT SD-OCT has increased the resolution to 5 microns and gives a three-dimensional view enhancing its diagnostic potential. Ultrasound B scan USG: It is a very useful tool, especially when the media is hazy and in cases with cataract or severe vitritis or vitreous hemorrhage. There is an indication for USG-B scan even when there is a relatively clear media in many posterior and panuveitic conditions.
It helps differentiate rhegmatogenous and exudative retinal detachment based on the shifting of fluid, which is more characteristic of an exudative retinal detachment.

An increased choroidal thickening can be a significant finding. It may be seen in Vogt Koyanagi Harada's disease VKH with significant posterior uveitic manifestations and in posterior scleritis. Normal choroidal thickness is around 1. It is also useful to diagnose intraocular tumors masquerading as uveitis and elevated mass-like lesions such as TB subretinal abscess.

Laboratory investigations Tailored lab investigation relevant to the clinical entity in question is the right approach in identifying the etiology of a posterior uveitic entity. Laboratory tests are more useful in infective than in non-infective conditions. Specific tests for each entity have been described later. In cases of diagnostic dilemma, intraocular fluid evaluation for polymerase chain reaction PCR and antibody titers helps clinch the diagnosis.
The treatment of the patient is incomplete without simultaneous treatment of the underlying systemic condition. The Table to the right provides a brief list of these etiologies for uveitis in children. Masquerade syndromes, such as leukemia, retinoblastoma, and JXG, can resemble intraocular inflammation. Children can present with unilateral or bilateral symptoms with or without conjunctival injection with the appearance of iridocyclitis with a pseudohypopyon or a spontaneous hyphema.
An year-old girl was referred for evaluation of panuveitis and presented with decrease in vision in her right eye for 1 month. On external examination, one can see leukocoria without injection A. Posterior segment examination revealed numerous white snowballs B. Further evaluation and ultimate enucleation revealed retinoblastoma. Retinoblastoma is the most common primary cancer to affect the eyes of children, with to cases per year in the United States and to per year worldwide.
Young infants presenting with unilateral heterochromia iridis, spontaneous hyphema, secondary glaucoma, and ocular inflammation should be suspected of having JXG. Traumatic uveitis can develop after blunt ocular trauma.
Severe inflammation after minor trauma may signal the presence of an underlying predisposition, such as human leukocyte antigen B27 HLA-B27 disease. Rosenbaum et al analyzed the records of patients seen in the uveitis clinic of a tertiary referral center to evaluate the role of nonpenetrating trauma in initiating uveitis. They found that 4. In a multicenter series of pediatric uveitis by Smith et al2 evaluating pediatric uveitis patients, the leading diagnoses were idiopathic uveitis BenEzra et al found that If a good examination cannot be completed in clinic, an examination under anesthesia may be required, especially if additional testing, such as fluorescein angiography, must be obtained.
Along with a complete examination, an extensive history with review of systems is needed to better direct laboratory testing. Previous infectious exposures, pets, travel, and review of systems should be elicited. The review of systems and onset of symptoms may be more difficult to obtain in children than in adults, especially in children who cannot communicate, as the ophthalmologist must rely on the parents.
Children also tend to adapt more readily and do not report problems at initial onset, presenting only after vision loss has occurred.
Current approach in the diagnosis and management of posterior uveitis
Just as in adults, there is no one formula for obtaining laboratory testing or diagnostic imaging for pediatric uveitis. Again, the review of systems must always be taken into account. Most patients with uveitis are assessed for, in the least, sarcoidosis, syphilis, and tuberculosis TB. Syphilis testing includes both nontreponemal testing such as rapid plasma reagin and the Venereal Disease Research Laboratory and treponemal testing such as fluorescent treponemal antibody absorption test or Treponema pallidum particle agglutination.
Testing for sarcoidosis includes obtaining chest x-ray, angiotensin-converting enzyme ACE serum level, and lysozyme level. ACE levels tend to be elevated in the pediatric population in general compared with the adult population, so elevated ACE alone may not be diagnostic of juvenile sarcoidosis; this is why chest x-ray and lysozyme level are helpful. Although computed tomography CT of the chest is often obtained looking for sarcoidosis in older patients, it should probably not be used as a screening tool in pediatric patients because of the radiation dose.
Other testing is directed by the history and examination. For example, a child with chronic bilateral anterior uveitis would have antinuclear antibodies ANA testing because JIA is a likely diagnosis, and a teenager with severe acute anterior uveitis in one eye would be given HLA-B27 blood test. For most cases of anterior uveitis, the ophthalmologist may start with complete blood count with differential, ANA, urinalysis, and HLA-B27, adding ACE, chest x-ray and CT chestand serum lysozyme, should juvenile sarcoidosis be suspected.
For intermediate uveitis, one would order the above and, again, follow clues from the review of systems. A history of camping or hiking in endemic areas would prompt testing for Lyme disease. Testing for TB and syphilis are a must. For adolescents presenting with intermediate uveitis, although it would be early, magnetic resonance imaging could be obtained to look for multiple sclerosis if the review of systems leads one to suspect that disease.
For posterior uveitis, noninfectious causes can begin with the above workup. When vasculitis is a concern, additional testing for myeloperoxidase and proteinase 3 can be ordered. In treating a child with uveitis, the ophthalmologist should use an approach similar to that used in adults and start with topical therapies if possible.
Although topical therapies may be enough for anterior uveitis, stronger medications are usually required for intermediate, posterior, and panuveitis, and parents should be made aware of this from the beginning. Should these topical therapies not be enough, if the child is cooperative, regional or intravitreal injections can be given.

If this cannot be done in clinic, an examination under anesthesia with concurrent treatment is recommended. Please note, the fluocinolone acetonide intravitreal implant 0. Systemic steroids would be the next step, but, unlike in adults, their long-term daily use in children is not recommended.
Long-term steroid use has been associated with growth retardation. Steroid-sparing immunosuppression can be considered, with the help of a pediatrician or pediatric rheumatologist.
