Assessment / Plan
Impression:
1. Occult multifocal choroidites OU with secondary macular
edema and optic disc edema
2. Iridiophacodenesis OU (secondary to Topamax)
3. Alternating horizontal nystagmus
 Plan:
– Further diagnostic work up of occult multifocal
choroiditis
– 40 mg prednisone po qAM

Topiramate (brand name Topamax) is an anticonvulsant (antiepilepsy)
drug. In late 2012, topiramate was approved by the United States Food and
Drug Administration (FDA) in combination with phentermine for weight loss. It is
also Food and Drug Administration (FDA) approved for, and most frequently
prescribed for, the prevention of migraines

Complications: Uveal effusion syndrome

Angle Closure Glaucoma
Acute myopia
Uveitis
Ciliary body edema
Uveal effusion
Ant. rotation of the lens and iris
Pathophysiology




Idiosyncratic effect: The most prevalent hypothesis is the
hapten hypothesis. The reactive drug metabolites bind to
the proteins on the zonular fibers of the lens and these
altered proteins are perceived as foreign and induce an
immune response.
Unrelated to dosage
Sulfonamides: Indapamide, Topiramate, Acetazolamide
Side effects start within the first 2 weeks
Treatment

Stop the offending medication
– Topiramate has a number of physiologic effects,
including inhibition of voltage-gated sodium and
calcium channels, augmentation of GABA-induced
chloride flux, inhibition of glutamate-related
excitatory neurotransmission and carbonic
anhydrase
Cycloplegia
 Corticosteroids
 IOP control if acute angle closure has occurred
