Management of acute proliferative diabetic retinopathy related complications during the first COVID-19 wave
Dhillon N; Santiago CBMC Ophthalmology 2022; 22: 119
BACKGROUND: Routine hospital eye services (HES) across the National health service (NHS), and diabetic eye screening (DES) in Scotland were paused during the COVID-19 lockdown in March 2020. Alternate pathways for managing acute ophthalmic pathology were devised in NHS Grampian covering the North-East of Scotland. Emergency eye treatment centres (EETC) manned by community optometrists were set up to treat and triage referrals to HES. METHODS: Retrospective study analysing consecutive patients referred to a tertiary eye centre (Aberdeen Royal Infirmary) with proliferative diabetic retinopathy (PDR) related complications between March and August 2020. General demographical data, diabetic history, visual acuity, ocular complication, type of management, time to follow-up, and any appointment cancellations were extracted for analysis. RESULTS: Fifty two eyes of 46 patients with PDR related complications were identified. HES appointment had been delayed or cancelled in 22 patients (48%) due to COVID-19. Mean age was 54.5 years (±15.1), 21 (46%) were female, 21 (46%) had type 1 diabetes; mean HbA1c was 78 mmol/l (±18.7). Vision ranged from 6/6 to perception of light. 36 (78%) patients had unilateral vitreous haemorrhage (VH), 6 (13%) bilateral, 2 (4%) tractional retinal detachments and 3 (6.5%) had neovascular glaucoma. Of 48 acute PDR presentations, 18 (38%) were given anti-VEGF within 72 h and two (4%) had PRP the same day. 16 (33%) were rebooked into the laser clinic, 13 (27%) referred for urgent surgical review, and 17 (35%) advised observation and review in clinic. After a median follow-up of 6 months, 12 eyes (23%) of 11 patients progressed to have vitrectomy. CONCLUSION: Despite lockdown, hospital appointment cancellations and recommended footfall reduction limiting capacity due to COVID-19, patients reaching out with PDR complications were promptly referred to HES and appropriate treatments carried out with COVID-19 precautions as recommended.
