A
Compresses
Tobradex (abx/steroid combo)
2
Q
Leukocoria
A
- White pupil
- Seen in infancy and early childhood
- strab and/or nystagmus can be present (mainly sensory)
- difference in eye size-bupthalmos, microphthalmos
- there could also be increase IOP, cataract, or tumor
- decreased vision
- may have ab APD

- myelinated nerve fiber
- coloboma
- RD
4
Q
Eval for leukocoria
A
- complete evaluation-history, pupils, IOP, AC, lens, retinoscopy, vitreous, fundus eval
- B scan
- radiology
5
Q
Treatment for leukocoria
A
Treat underlying problem
6
Q
Prognosis of leukocoria
A
Poor to guarded prognosis (depending on the cause)
7
Q
Phthisis bulbi
A
- function has decompensated
- eye shrinks after trauam, surgical truama, loss if function
- soft, low IOP
- intraocular disorganization
- B scan to rule out growths
- non painful blind eye
- enucleation, if it becomes a painful blind eye
8
Q
Uveitis in chidlren
A
- more in females
- just like in adutls
- 62% are Caucasian
- major etiologies: idiopathic and juvenile idiopathic arthritis
9
Q
Classifications of uveitis
A
Based on
- anatomical location (anterior, intermediate, posterior, or panuveiits)
- pathology (granulomatous or non granulomatous)
- course (acute, chronic, or recurrent)
- etiology (traumatic, immunologic, infectious, or idiopathic)
10
Q

A
Sarcoidosis TB Syphilis Lyme MS Idiopathic intermediate uveitis
12
Q
Post uveitis and panuveitis diffdx

13
Q
Juvenile idiopathic arthritis (JRA)
A
- anterior uveitis
- arteritis of at least 6 weeks without identifiable cause in chidlren < 16
- most common cause of anterior uveitis in chidlren
- risk of uveitis greater in the 1st 4 years after JRA diagnosis
- can be seen before or after joint symptoms
- more aggressive course if the interval between the arthritis and uveitis is short
- run antinuclear antibody lab (ANA)
14
Q
Characteristics of anterior uveitis from JRA
A
- usually bilateral
- non-granulomatous with fine to medium KPs
- granulomatous precipitates can be seen in some kids
- chronic inflammation can lead to: band K, postieror synechiae, hypotony, cataract, glaucoma
- important for uveitis screening for children with JRA, especially in the 1st 4 years diagnosis. With with PCP on this
15
Q
Intermediate uveitis in kids
A
-inflammation at the vitreous base over the CB, pars plana, anterior vitreous and peripheral retina
can occur with any of these disorder
- sarcoidosis
- TB
- Syphilis
- Lyme
- MS
- Idiopathic (pars planitis)
Snow banking
Vitreous cells
16
Q
Toxoplasmosis
A
- posterior uveitis
- caused by toxoplasma Gondi
- cats are host
- cat feces can be ingested by animals and humans
- congenital or acquired from eating undercooked infected meat or contaminated water
- predilection for heart muscle, neural tissue and the retina
- reunion ELISA
17
Q
Characteristics of toxoplasmosis
A
- remains dormant until cyst erupts
- systemic infection present as fever, lymphadenopathy, sore throat
- can also be congential via transplacental transmission
- once of the TORCH congenital infections
18
Q
TORCH congential infections
A
Toxoplasmosis
Rubella
CMV
Herpes
19
Q
Signs and symptoms of toxoplasmosis
A
- manifests as retinitis, choroiditis, iritis
- the active area of retinal inflammation is thickened and cream colored with overlying vitritis in the macualr scar
- Atrophic chorioretinal scar (satellite lesion)
- Dx based on the characteristic retinal lesion
- inflammation can come from reactivated toxoplasmosis
- systemic treatment includes antimicrobals with or without oral steroids
- vision can be compromised based on where the lesion is
20
Q
Toxocariasis
A
- posterior uveitis
- nematodes in dogs and cats
- primarily in kids
- contracted though ingestion of soil contaminated by dogs and cats
- usually unilateral and not associated with systemic problems
- average age of onset is 11
- could appear as post pole granuloma, peripheral granuloma or endophthalmitis
- run ELISA
21
Q
Appearance of toxocaraisis
A
- no external evidence of inflammation
- leukocoria, strab, or decreased VA present
- treatment by observing the peripheral lesion
- periocular or systemi steroids for the posterior lesions and endophthalmitis
- or surgical intervention for retinal traction, cataract, glaucoma
- parasite already dead so no anti parasitic
22
Q
Sarcoidosis
A
- panuveitis
- if in kids under 5, there is a triad of uveitis, arthritis, and each
- in older kids, there ar pulmonary abnormalities and lymph node abnormalities (as seen in adutls)
- anterior uveitis is the most common but there can be panuveitis
- diagnosis and treatemtn is simialr to adults-ACE and chest X ray
- ACE in healthy kids higher than in adutls so can be misleading so careful systemic diagnosis

Uveitis managements
- eliminate inflammation before complications
- anterior: topical corticosteroids and cycloplegic agents
- sub-tenon steroid injections can be used to improve penetration for intermediate or postieror
- pred forte every 2 hours then taper, atropine 1% BID
- RTO frequently for IOP check (watch for steroid responders)
- short course of oral steroids. Caution with use
- glaucoma and cataracts are complications after oral steroids
- risk of systemic steroids include, growth retardation, osteoporosis and fractures, DM, HTN, diopathic intracranial HTN (pseudotumor)
- NSAIDs, be careful of GI probs
- systemic immunosuppressive therapy
- methotrexate
44
Surgeries for uveitis
Chidlren may need surgeries for uveitis complications
Indicated for
- band K
- cataracts
- glaucoma
