Changes in emergency glaucoma care during the COVID-19 pandemic in South India.

PURPOSE

To assess the differences in the pattern of presentation of glaucoma emergency conditions during the various phases of pandemic-related travel restrictions: first wave-related lockdown, unlock period, and the second wave-related lockdown.

METHODS

The number of new emergency glaucoma conditions, the various diagnoses, and the total number of all new glaucoma patients presenting to the glaucoma services at five tertiary eye care centers in south India from 24 March 2020 to 30 June 2021 were collected from the electronic medical records and were analyzed. The data were compared with the corresponding time period in the year 2019.

RESULTS

In total, 620 patients presented with an emergency glaucoma diagnosis during the first wave-related lockdown as against 1337 during the same period in 2019 (P < 0.0001). During the unlock period, 2659 such patients visited the hospital compared with 2122 in 2019 (P = 0.0145). During the second wave-related lockdown, there were 351 emergency patients compared with 526 patients in 2019 (P < 0.0001). Lens-induced glaucomas (50.4%) and neovascular glaucoma (20.6%) were the most common diagnoses during the first wave-related lockdown. During the unlock period, there was a greater proportion of neovascular glaucoma (P = 0.0123). The second wave-related lockdown had a greater proportion of phacolytic glaucomas (P = 0.005) and acute primary angle closure (P = 0.0397) patients.

CONCLUSION

The study demonstrates that emergency glaucoma care was grossly underutilized by the people during the lockdowns. Trivial conditions like cataracts or retinal vascular diseases if not treated appropriately may progress to become emergencies in the future.
