Treatment of Endophthalmitis With Preservation of
the Uninvolved Crystalline Lens
  • Justin H. Townsend, MD
  • Harry W. Flynn, Jr., MD
  • The authors have no financial interest in the
    subject matter of this poster

2
Background
  • Large studies show endophthalmitis most commonly
    develops following cataract surgery
  • Endophthalmitis can also develop in phakic eyes
  • Endogenous spread
  • Post-operative (glaucoma, PPV)
  • Post-traumatic
  • The crystalline lens is often removed via a pars
    plana lensectomy with PPV during the treatment of
    endophthalmitis
  • Evidence is limited regarding the treatment of
    endophthalmitis without removal of the uninvolved
    crystalline lens
  • The purpose of this study is to demonstrate the
    successful treatment of endophthalmitis without
    removal of the uninvolved crystalline lens

3
Methods
  • Retrospective, non-comparative case series
  • January 1980 to June 2009
  • Bascom Palmer Eye Institute
  • Culture-positive endophthalmitis managed without
    removal of the crystalline lens
  • Patient records reviewed
  • Demographic information, etiology of infection,
    presenting clinical features, pathogen
    identification, treatment modalities, pre- and
    post-treatment lens status, visual acuity outcome
    and duration of follow up

4
Results
  • 24 phakic eyes of 22 patients were identified
  • Etiology of infection
  • Endogenous 13, Post-operative 9,
    Post-traumatic 2
  • Treatment Modality
  • PPV intravitreal Abx 14
  • Intravitreal Abx alone 10
  • Average duration of follow up 18.4 months
  • 7/24 eyes went on to have routine cataract
    extraction during follow up period
  • No surgeries noted to be complicated
  • Final VAs 20/20, 20/25, 20/40, 20/60, 20/80,
    20/400 (macular scar), 20/100 (macular scar)

6
Results
  • Final visual acuity by etiology of infection

7
Results
  • Final visual acuity by treatment modality

8
Results
  • Cataract progression by treatment modality

9
Results
  • Degree of cataract progression by treatment
    modality

10
Conclusions
  • Successful treatment of endophthalmitis was often
    achieved while preserving the uninvolved
    crystalline lens
  • Progression of cataract was frequently seen in
    this series
  • Successful treatment of endophthalmitis without
    removal of the crystalline lens can avoid
    placement of a posterior chamber intraocular lens
    in an actively infected eye
  • Standard cataract surgical techniques can be used
    later with good results
