! At least 14% of population infected by age 40 ! 1,000,000 + infected each year ! Most common retinal infection in US – about 2%
of all those infected have ocular involvement ! 20,000 develop ocular lesions each year ! Symptomatic retinitis in 0.2% to 0.7% of those
infected (2000–7500/year; midpoint ~5000) ! New lesions may develop over years after
infection so incidence may be higher

CLINICAL CHARACTERISTICS OCULAR INVOLVEMENT
! Asymptomatic in most immunocompetent patients ! Eye pain, photophobia, epiphora, blurred vision ! Eye disease may reactivate months to years later
! Further damage to retina ! Progressive loss of vision if central retinal structures
involved ! Can lead to blindness

DIAGNOSTIC CONSIDERATIONS HISTORY OF PRESENT ILLNESS
! Complaints of fever, myalgia, fatigue, headache, rash, sore throat
! Exposure to cat feces, undercooked meats ! Active ocular disease – blurred VA, floaters,
metamorphopsia

DIAGNOSTIC CONSIDERATIONS OCULAR EXAMINATION
! Decreased VA ! Congenital disease
! Strabismus ! Microphthalmia ! Cataract ! Optic atrophy ! Nystagmus ! Retinal detachment
! Retinal exam – old retinochoroidal scars
![Page 33: 2016 The Eyes Have It...CLINICAL CHARACTERISTICS OCULAR INVOLVEMENT ! Proliferative diabetic retinopathy (PDR) !

! Treatment dependent on several factors ! Acquired disease in
immunocompetent often requires no Rx
! Minimal inflammation, peripheral ocular lesions, VA minimally affected – lean toward no Rx
! No studies show extent Rx alters course of disease
! Immunocompromised patients ! Various antibiotic regimens
(sufadiazine, pyrimethamine, clindamycin, azithromycin, TMP/SMX, e.g.)
Treatment
