Study Details

Study Description

Brief Summary

The purpose of this study is to examine the efficacy and safety of autologous serum eye drops in people with recalcitrant dry eye.

Condition or Disease Intervention/Treatment Phase
  • Drug: Autologous serum eyedrops
Phase 1

Detailed Description

A group of selected dry eye patients from the Singapore National Eye Centre who have exhausted the usual treatment options (lubricants, topical immunosuppressive and punctal occlusion) and not keen for tarsorrhaphy will be recruited. After informed consent, they will undergo plasmapheresis and start on daily autologous serum eyedrops for a period of 4 months. Clinical monitoring for standard dry eye parameters such as punctate corneal keratitis, Schirmers testing, tear break up time as well as severity and frequency of dry eye symptoms will be conducted. Tear inflammatory proteins captured on Schirmers paper pre and post treatment will be analysed as well.

Outcome Measures

Primary Outcome Measures

  1. Staining [4 months]

    Grading of punctate corneal staining in the worse eye (second visit relative to first visit)

Secondary Outcome Measures

  1. Symptoms [4 months]

    The change in Visual Analog Score (Schaumberg D et al Ocular Surface 2009). The global score is calculated from 2 scores, the frequency and severity of dry eye symptoms. From .

  2. Tear-production [4 months]

    Schirmers test result

  3. Tear-proteins [4 months]

    Tear protein analysis

  4. Tear-stability [4 months]

    Tear break up time

  5. Cornea [4 months]

    other corneal findings such as scarring, vascularisation, filaments etc

  6. Conjunctiva [4 months]

    Documentation of conjunctival hyperemia, chemosis, scarring
