Clinical Trial Summary

Diabetic retinopathy (DR) is a challenge to ophthalmic practice in communities with poor socioeconomic development. The COVID 19 pandemic has accentuated the challenge. DR is one of the leading causes of vision loss worldwide, estimated to account for 1.25% of moderate to severe visual impairment and 1.07% of blindness. Pan retinal photocoagulation (PRP) remains the gold standard treatment for preventing visual loss in PDR. Scatter photocoagulation is not recommended for eyes with mild or moderate non-proliferative diabetic retinopathy (NPDR) provided careful follow-up can be maintained,. When retinopathy is more severe, scatter photocoagulation should be considered and should not be delayed if the eye has reached the high-risk proliferative stage. As many as 27% of patients with moderate NPDR are estimated to progress to PDR in 1 year; therefore, they should be seen every 4 to 8 months. This ideal, good as it is, is not what ophthalmic practice has to deal with in communities of low-resource settings, where patients often seek medical advice due to visual complaints from the complications of PDR without being diagnosed in the non-proliferative stage or high risk PDR. Screening protocols are not followed, a situation aggravated during the COVID pandemic lockdown.
