A 56-year-old woman presents with an acute angle closure attack that occurred 24 hours after COVID-19 vaccination in a patient with plateau iris. Description She was given the option of medical management with topical pilocarpine or phacoemulsification. At the moment, we do not suggest there is a need to change current practise or to warn patients with a history of angle closure glaucoma undergoing COVID-19 vaccination, but we would highlight the importance of reporting these rare events.
To our knowledge, this case report is the first to report an acute
angle closure attack that occurred 24 hours after COVID-19 vaccination
in a patient with plateau iris. Possible mechanisms that may
support this association are discussed [1].
A 56-year-old woman presented to the Department of Ophthalmology
with a 1-day history of pain in her right eye after having
her COVID-19 booster vaccination with a recombinant vaccine
(Janssen) one day before. Her past ocular history includes plateau
iris and two previous episodes of acute angle closure attacks in
her right eye, which were managed first with peripheral laser iridotomy
and second with an argon laser peripheral iridoplasty in
December 2019. She has not had another acute attack or been on
any IOP lowering drops for more than two years. Her past medical
history included dry eyes. There was no significant medical or family
history [2].
On presentation to the eye casualty, her right visual acuity (VA)
measured 6/30 unaided (6/12 with pinhole correction). The left
eye VA was 6/12. Intraocular pressures with Goldmann applanation
tonometry measured 48 mmHg (right) and 16 mmHg (left).
The anterior chamber was deep in the affected and non-affected
eyes. Gonioscopy revealed a closed anterior chamber angle of 360
degrees and a patent iridotomy in her right eye. Examination of the
optic nerve revealed a healthy neuroretinal rim [3].
Initial management included medical therapy. This included i-v
acetazolamide, topical iopidine, timolol, latanoprost, brinzolamide,
and pilocarpine. The IOP normalized to 15 mmHg in the right eye.
VA also became more normal. She was discharged for outpatient
follow-up with pilocarpine 1% TDS, Timolol 0.5% BDS, Prednisolone
1% QDS, and oral acetazolamide 250 mg TDS. On review the
following week, her IOP was 6 mmHg in the right eye and 10 mmHg
in the left eye. Gonioscopy showed an appositionally closed angle
but without synechial closure in her right eye. She was given the
option of continuing 1 drop of pilocarpine 2% three times a day for
her right eye indefinitely or right eye phacoemulsification. She expressed
a preference for pilocarpine 2% as a part of her long-term
management plan with regular follow-up to monitor the IOP [4].
Ocular complaints secondary to COVID-19 infection and after
prone position have been reported in the literature, such as acute
angle glaucoma, ocular surface complaints, and ocular pain1-2. Ret-rospective case series or isolated case reports have highlighted ocular adverse effects of the COVID-19 vaccination, such as facial nerve
palsy, abducens nerve palsy, optic neuropathy, uveitis, acute macular
neurocristopathy, central serous retinopathy, and thrombosis.
3-4 This is the first case to our knowledge, exploring the association
of acute angle closure glaucoma secondary to a COVID-19 vaccination.
While the association has been observed, there is uncertainty
regarding its causality and correlation. It has been hypothesized
that the body’s immune response to COVID-19 vaccinations may
contribute to the pathogenesis of adverse ocular events3. Another
possible explanation may be stress-induced activation of the sympathetic
nervous system. An alternative mechanism would be small
choroidal effusions, but this is unlikely as the anterior chamber
depth remained deep in both eyes and only one eye was involved.
At the moment, we do not suggest there is a need to change current
practise or to warn patients with a history of angle closure glaucoma
undergoing COVID-19 vaccination, but we would highlight the
importance of reporting these rare events.
