Visual Outcome in Pars Plana Vitrectomy for Acute Postoperative Endophthalmitis after Cataract Surgery
Purpose: To determine the visual outcomes in patients undergoing pars plana-vitrectomy (PPV) for acute postoperative endophthalmitis after cataract surgery.
Study Design: Quasi experimental study.
Place and Duration of Study: Al- Ibrahim Eye Hospital, Malir, Karachi for a period of 2 years.
Material and Methods: Thirty-three patients were selected using non-probability convenient sampling technique.
Patients with acute postoperative endophthalmitis after cataract surgery diagnosed clinically and on B-scan, with
visual acuity of only perception of light were included while patients with better visual acuity and any other types
of endophthalmitis were excluded. PPV was performed in all cases and the patients were examined postoperatively
on 1st day, 3rd day, 1, 2 and 3 weeks after surgery. During these follow ups, visual acuity was
recorded, detailed slit lamp and fundus examination was performed. Using SPSS version 20.0, chi-square test
was applied to test for significance keeping p-value of < 0.05 as significant.
Results: Out of 33 patients 19 (57.6%) were males and 14 (42.4%) were females. Mean age of the patients was
54.50 ± 14.14 years. On 1st post-operative day 8 patients (24.2%) showed improvement of visual acuity from
perception of light to finger counting while 02 (6.1%) patients reported visual acuity of 6/60. On final visit at 3rd
week postoperatively, 19 patients (57.6%) had visual acuity of finger counting, 08 patients (24.2%) had hand
movement and 06 (18.2%) patients reported a visual acuity of 6/60.
Conclusion: PPV for acute post-cataract endophthalmitis results in favourable outcomes in terms of visual acuity.
