In a retrospective study, a combined 20 and 23-gauge pars plana vitrectomy procedure was performed in 21 eyes for various indications and proposed as a transition procedure to 23-gauge transconjunctival vitrectomy. Through use of combination of procedures postoperative complications, surgical trauma and healing time was decreased; operating time was reduced; costs were decreased.

Groups/Cohorts Assigned Interventions
vitrectomy Procedure: 20 and 23 gauge pars plana vitrectomy


Ages Eligible for Study:   44 Years to 80 Years
Genders Eligible for Study:   Both
Sampling Method:   Non-Probability Sample
Study Population
Patients who were in the range 44 to 80 years, who had to undergo vitrectomy operation with different diagnosis were included in the study. Each participant had a complete ophthalmological examination which included best-corrected visual acuity (BCVA), slit lamp examination with and without pupil dilation, intraocular pressure (IOP) measurement with applanation tonometry and stereoscopic evaluation of the ocular fundus before decision of operation.

Inclusion Criteria:

  • eyes requiring pars plana vitrectomy for various indications: such as dropped lens, intraocular blood, retinal detachments...etc.

Exclusion Criteria:

  • patients who did not observed periodically during postoperative period.
