Pak J Ophthalmol Jan ;36(4):6-7.

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, patients registration number and address was recorded. Every patient had detailed preoperative work-up; including best corrected visual acuity by Snellens 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.
