Acute glaucoma attack in a patient recovered from coronavirus infection (case report)

Abstract

The prevalence of ophthalmic manifestations in COVID-19 ranges from 2 to 32%. The most common ophthalmic disease associated with COVID-19 is viral conjunctivitis, but there are also reports of cases with episcleritis, uveitis, occlusions of the central retinal artery and vein, retinopathy, glaucoma, dry eye syndrome, as well as rare neuroophthalmological manifestations such as diplopia, ophthalmoplegia and nystagmus. This study reports a case of bilateral acute angle-closure glaucoma attack in a patient recovered from severe COVID-19 pneumonia.PURPOSE. To determine the causes of bilateral acute angle-closure glaucoma attack associated with COVID-19 pneumonia, and to evaluate the effectiveness of laser iridotomy and transciliary drainage of the posterior chamber of the eye.METHODS. Bilateral acute angle closure glaucoma attack was observed in a female patient recovered from COVID-19 pneumonia. Low hypermetropia and co-existing cataract were diagnosed in both eyes. In order to normalize the IOP and restore visual acuity, laser iridotomy was performed in both eyes, followed by surgical treatment of glaucoma with transciliary drainage of the posterior chamber in both eyes. After that the patient underwent phacoemulsification with implantation of intraocular lenses (IOL) in both eyes.RESULTS. Laser iridotomy and transciliary drainage of the posterior chamber was performed in both eyes. The target IOP without topical therapy and stabilization of glaucoma were achieved in both eyes. The second step was phacoemulsification with implantation of IOL, which significantly improved visual acuity of both eyes.CONCLUSION. COVID-19 can lead to vision loss and disability, therefore IOP should be monitored in patients that remain in prone position for ventilation for extended periods of time and receive systemic steroid medications. This is especially relevant for patients with a predisposition to glaucoma or with diagnosed glaucoma.
