Objectives: To determine the frequency and severity of surgical Vitreo-Retinal diseases during COVID-19 lockdown period (LP) and compare it with same period last year. Methods: Single hospital based retrospective Cohort Study. Data of the patients that underwent retinal surgeries during the COVID-19 LP i.e., 23-03-2020 till 23-06-2020 and same period last year i.e., 23-03-2019 till 23-06-2019 was analyzed. Results: One hundred thirty-six eyes of 105 patients were included. Among these eyes, 48 (35.3%) were operated during the COVID-19 LP while 88 (64.7%) were operated during the same time last year. A decline of 45.5% (p=0.023) was observed in the frequency of surgeries during the LP. Mean age of patients during the LP was 43.2 ± 20.3 years compared to 48.4 ± 17.9 years last year. There was reduction in the surgeries for Diabetic Tractional Retinal Detachment (11.4% vs 4.2% during LP, p=0.166), Vitreous hemorrhage (10.2% vs 8.3% during LP, p=0.04), Full thickness macular hole (3.4% vs 0% during LP) and Epiretinal membrane (12.5% vs 0% during LP). While Rhegmatogenous retinal detachment (27.3% vs 58.3% during LP, p<0.001) among other disorders had a higher proportion during the LP. Conclusion: The decline in the frequency of retinal surgeries during the LP is indicative of complex pathologies presenting later with more advanced disease. However, earlier presentation and an increase trend in surgeries for RRD during the LP shows the positive impact of free time on the health concerns of our population. doi: https://doi.org/10.12669/pjms.37.7.4291 How to cite this:Awan MA, Shaheen F, Mohsin F.

The objective of this article was to report the clinical and surgical outcomes of diabetic tractional retinal detachment (TRD) with 27-gauge plus pars plana vitrectomy (27G+ PPV) MethodsThis is a retrospective, consecutive cohort study of 196 eyes of 176 patients that underwent 27G+ PPV for TRD from July 2015 to June 2019 at the ophthalmology department of Shifa International Hospital, Islamabad. The outcomes include primary and secondary anatomical attachment of the retina, bestcorrected visual acuity, and post-operative complications. ResultsThe mean age of the patients in this study was 55.3 ± 11.3 years. Out of 176 patients, there were 47.2% (n=83) females. The mean operating time calculated was 60 ± 36 min (range 22-130 min). Of 196 eyes, 64.3% (n=126) also combined phacoemulsification with lens implantation. Internal limiting membrane peeling was done in 11.7% (n=23) of the cases. Post-operatively, 98% (n=192) achieved primary retinal attachment, and 1.5% (n=3) underwent a second procedure to achieve retinal attachment. At three months follow-up, the mean best corrected visual acuity (BCVA) remarkably improved from 1.86 ± 0.59 to 0.54 ± 0.32 logarithm of the minimal angle of resolution (logMAR) (p-value<0.001). Among complications, one patient had intraoperative suprachoroidal oil migration, which was managed successfully, while post-operatively, 11 patients (5.6%) developed a transient rise in intraocular pressure, which was controlled with anti-glaucoma drugs, and one patient had vitreous cavity hemorrhage which resolved on its own with time. ConclusionThis study strongly suggests that the 27G+ PPV offers successful repair of eyes with diabetic TRD with statistically significant improvement in visual acuity and minimal rate of complications.
