Abstract

Objective

To assess the visual outcome in the patients of diabetic retinopathy after panretinal photocoagulation.

Method

Over a period of 11 months, 54 eyes of 26 patients with severe &very severe NPDR and PDR were prospectively
followed up. Visual outcome was assessed thrice i.e after one, two and three months follow-up. A prospective
interventional study was done at NMDC from Jan 2018 to Nov 2018. Patients have different types of systemic illness like
hypertension, connective tissue disorder are excluded for this study.

Results

In all groups patients pre treatment level of visual acuity checked. After one month followup few patients
decrease their visual acuity and it was due to inflammatory edema caused by laser. After that almost all patients maintained
their pre treatment level of visual acuity level.one patient suffer from vitreous haemorrhage and it is most likely due to poor
metabolic control.

Conclusion

Timely PRP save the vision of patients and prevent it's complications. It also save the patients from
permanent Blindness. Pattern laser make the PRP easily and save the time as well as postural problem of patients and
doctors.

Keywords
