1. exam
   1. red reflex- if immature, still occurs, if dense cataract, no red reflex
2. presentation
   1. blurred vision
      1. if unilateral, often unnoticed (but loss of steropsis affects distance judgement)
      2. bilateral cuase gradual loss of vision (freq glasses changes) +/- dazzle, +/- monocular diplopia
3. treatment
   1. surgery: if troubling, lifestyle restricted, or unable to read while driving

      Anmerkungen:

      • complics: capsule thickening i%, easily treated by capsulotomy   astigmatism, eye irritiaon, anterior uveitis
      1. ideally day case, local anesthetic, small incision surg + phacoemulision + intraocular lens implant

1. dull, constant, aching pain over frontal or maxillary sinus, with tender overlying skin +/- postnasal drip. pain worse on bending over.
2. ethmoid or sphenoid sinus pain: deep in midline at root of nose. common w/coryza.
3. pain lasts 1-2w

1. CT can confirm diagnosis but is rarely needed
2. investig not recommend unless complications or chronic 12+ w

1. viral or bact infect, or allergy or autoimmune
   1. upper rest tract infect, usually virus, is most common cause of acute (incl rhinoviruses, coronaviruses, influenzaviruises)
