-silicone oil (RD)
-hx:
–symptoms: onset, progression (pain, vision loss, bothersome)
–RFs: any of the above diseases

Mgmt:
- gonorrhea: irrigate
–if no K involvement: IM CTX x1 dose
–if yes K involvement: IV CTX x3 days
- chlamydia: PO erythromycin x 2wks, neonatologist referral because chlamydial infections can have systemic co-morbidities (PNA, GI)

mgmt of RB
- refer to oculo-oncology, genetic counseling (1/3 inherited)
- if small: cryo and PRP
- if unilateral and advanced w low visual potential: enuc
- if b/l large tumors: chemoreduction + cryo/PRP
- if refractory vitreous seeding: intravitreal / intra-arterial melphalan
- if extraocular: chemo + surgical reduction
- f/u q3mo to monitor recurrence / involvement of fellow eye
- counsel:
–fatal if untreated, 95+% survival rate if treated
–if germline mutation, then avoid radiation given risk of secondary malignancy
–life long surveillance needed for secondary tumors like osteosarcoma

3. covered eye flicks in seconds after uncover
-alternate cover
-Hirschberg
-Krimsky
-is there heterotropia? Which eye is preferred?
1. no tropia / preferred fixating eye
2. exophoria
3. intermittent extropia
- elicits tropia + phoria
- estimate of deviation based on light reflex: 30PD @ pupil, 60PD @ iris, 90PD @ limbus
- requires no patient cooperation
Duane’s syndrome
-pathophys
-presentation
-types
- workup
-goal of surgery
-counsel
pathophys: no CN6 nucleus -> LR innervated by aberrant branch of CN3 = non-progressive
retraction +/- upshoot / downshoot on adduction + palpebral fissure narrowing
1: abduction deficit = ET
2: adduction deficit = XT
3: abduction and adduction deficits = ET/XT/ortho
none needed for duane (if suspicious for other etiologies, then CT/MRI brain for muscle restriction or compressive lesion or intracranial HTN)
expand field of binocular vision: MR and/or LR recession +/- transposition of SR/IR
prognosis good with surgical correction if no amblyopia; counsel regarding risks of strab surgery (sebsequent misalignment)
mgmt of congenital ET
-if accomodative (>+2D), full correction. If straight in distance and ET at near, 2.5D executive bifocal
-if amblyopia, patch (start w 2hrs/day while engaged)
-if congenital, b/l MR recession
-counsel re goals of treatment: cosmetic and to preserve stereopsis. Warn about risk of subsequent alignment issues
VA test based on age
1. <2yo
2. 2-5yo
3. >5yo
- preferential looking (prefers stripes vs homogenous card) / Teller acuity (grates)
- Allen cards (pictures)

angle kappa
-angle between visual axis and pupillary axis.
-Patient has manifest strabismus on hirschberg / Krimsky but no misalignment on cover-uncover testing
-Can be positive (XT) or negative (ET) due to macular dragging.

– superficial lesions: topical timolol or laser (older tx was intralesional steroid w risk of retrograde CRAO)
– deep lesions: PO propranolol (first rule out PHACES, administer under supervision from pediatrician 2/2 bradycardia) - if severe amblypia and increasing lesion size, consider surgical excision
-eval for:
–PHACES: posterior fossa, hemangiomas, arterial, cardiac, eye (morning glory), sternal
–Kassabach Merritt: hemangioma + thrombocytopenia (consumptive coagulopathy) and hemolytic anemia - natural course: progress over first year, then gradually resolves over first 4 years
- good prognosis if no amblyopia

- refraction to maximize vision
- usually the result of trauma so fix other sequelae such as capsule violation w lensectomy w aphakic contact lens, RD w PPV
- if vision is good (no diplopia), then can observe
-if systemic disease is suspected, then refer to pediatrician for workup:
–Marfan: cardiac echo for cardiac valve involvement; warrants abx ppx for surgery if cardiac defects to prevent endocarditis
–Homocystinuria: sodium nitroprusside testing - HIGHER RISK OF THROMBOEMBOLIC EVENTS DURING GENERAL ANESTHESIA
-counsel
