NCT06038968

Brief Summary

The goal of this interventional clinical trial is to assess anatomical and functional outcomes of methotrexate use in irrigating fluid during parsplana vitrectomy combined with intrasilicone injection at end of surgery in patients with advanced proliferative diabetic retinopathy. The main questions it aims to answer are:

  1. 1.Does methotrexate use in irrigating fluid during parsplana vitrectomy combined with intrasilicone injection at end of surgery decrease the post operative vitreoretinal proliferation after vitrectomy in patients with advanced proliferative diabetic retinopathy?
  2. 2.Does methotrexate use in irrigating fluid during parsplana vitrectomy combined with intrasilicone injection at end of surgery improve post operative functional outcome after vitrectomy in patients with advanced proliferative diabetic retinopathy?

Outcome Measures

Primary Outcomes (2)

  • assess retinal layers by optical coherence tomography

    presence of epiretinal membrane, cystic changes in retina, central macular thickens

    one month after pars plana vitrectomy and one month after silicone oil evacuation

  • assess functional outcomes by multifocal electroretinogram

    latency and amplitude of main P wave

    one month after pars plana vitrectomy and one month after silicone oil evacuation

Secondary Outcomes (2)

  • Anterior segment slit lamp biomicroscopic examination

    one month after pars plana vitrectomy

  • visual acuity

    one month after pars plana vitrectomy and one month after silicone oil evacuation

Study Arms (2)

Methotrexate group

EXPERIMENTAL

methotrexate group will receive 40 mg of MTX in 500 ml of irrigation fluid during vitrectomy and 250 ug intra-silicone oil injection at the end of vitrectomy

Drug: Methotrexate 25 MG/MLProcedure: parsplana vitrectomy

Control group

PLACEBO COMPARATOR

control group will not receive MTX in irrigation fluid during vitrectomy nor intra-silicone at the end of vitrectomy

Procedure: parsplana vitrectomy

Interventions

Methotrexate is a folate derivative that inhibits several enzymes responsible for nucleotide synthesis. This inhibition leads to suppression of inflammation as well as prevention of cell division.

Also known as: Methotrexate Mylan 50 mg/2 mL
Methotrexate group

Pars plana vitrectomy (PPV) is a technique in vitreoretinal surgery that enables access to the posterior segment for treating tractional retinal detachment in advanced proliferative diabetic retinopathy, in a controlled, closed system.

Control groupMethotrexate group
