Abstract

Purpose:  To compare the frequency of post-operative hypotony between 23G PPV and 25G PPV in advanced diabetic eye disease.

Study Design:  Quasi experimental study.

Place and Duration of Study:  Study was conducted at department of Ophthalmology, Lahore General Hospital, Lahore from 7th April 2016 to 6th October 2016.

Methods:  Total 100 cases of advanced diabetic eye disease with age ranging from 25 – 65 years and either gender were selected. Patients with nystagmus and claustrophobia, lamellar macular holes, epiretinal membrane and neovascular glaucoma were excluded. Patients were divided by lottery method into 2 groups. Data of the patient i.e. name, age, sex, patient’s registration number and address was recorded. Every patient had detailed preoperative work-up; including best corrected visual acuity by Snellen’s chart, intraocular pressure by applanation tonometer, indirect ophthalmoscopy and B-scan for retinal status. Group A underwent 23G PPV and group B underwent 25G PPV. Patients were followed after 24 hours of surgery to measure intraocular pressure to access hypotony.

Results:  Mean age of patients in group A was 50.16 ± 10.40 years and in group B was 50.26 ± 9.91 years.
Out of 100 patients 57 (57.0%) were females and 43 (43.0%) were males, with female to male ratio of 1.1:1.
Post-operative hypotony was seen in 24 (48.0%) patients with 23G PPV and 02 (4.0%) patients with 25G PPV
(p-value = 0.0001).

Conclusion:  This study concluded that the frequency of post-operative hypotony in 23G Pars Plana Vitrectomy was higher as compared to 25G Pars Plana Vitrectomy in advanced diabetic eye disease.

Key Words:  Diabetic retinopathy, Pars Plana Vitrectomy, Hypotony.
