Summary and Conclusion
The aim of this study was to compare the corneal topographic changes after 23-guage transconjunctival sutureless vitrectomy (TSV) to those occuring after standard 20-guage pars plana vitrectomy (PPV).
This study included 40 patients who were indicated to undergo primary vitrectomy for vitreoretinal pathologies. They were randomly divided into 2 groups;
- Group 1 included 20 patients in whom 23-gauge TSV was done.
- Group 2 included 20 patients in whom 20-gauge PPV was done.
Patients with history of corneal trauma, scars or haze, previous ocular surgery, corneal disease found upon slit lamp examination or corneal topography, conjunctival or scleral scarring, IOP outside the range of 6-26 mmHg, postoperative significant corneal opacity, and a failed surgery were excluded from the study.
Preoperative evaluation was done in the form of complete history, complete ophthalmological examination and Corneal topography using the Pentacam.
All cases were evaluated postoperatively by corneal topography using the Pentacam which was obtained one week, one month and three months postoperative and intraocular pressure (IOP) measurement. The patient’s medical records were reviewed and surgical and ocular parameters were recorded.
Postoperative anterior corneal elevation showed a significant (P
