Regresses over 2-3 weeks & can cause retinal traction & tears leading to retinal detachment Treatment: IV and PO acyclovir Can result in retinal detachment Prophylactic laser photocoagulation is considered beneficial following resolution of retinitis.

Cataracts are the leading cause of blindness worldwide Early development and/or more rapid progression in diabetics and with corticosteroid use Indications for Surgery Primary: visual function that no longer meets the patient’s needs and for which cataract surgery provides a reasonable likelihood of improved vision Secondary: anisometropia, interference with optimal diagnosis or management of posterior segment conditions, causing inflammation, inducing angle closure Cataract Screening Recommendations for Adults14 Age 20-29: a complete eye exam at least once Age 30-39: a complete eye exam at least twice Age 40-64: baseline exam at 40, then follow-up as per ophthalmologist Age > 65: every 1-2 years Patients with risk factors for eye disease – family history, history of eye injury, diabetes, hypertension, etc. should be seen regularly Patients with symptoms – i.e. flashes, floaters, visual changes or distorted vision, etc. should be seen as soon as possible QUESTIONS?
