Posterior vitreous detachment and electroconvulsive therapy: Insights from a case

A case of bilateral posterior vitreous detachment after electroconvulsive therapy (ECT) has been reported previously in the literature. There is not enough evidence about ocular side effects of this treatment. The literature supports a slight increase in intraocular pressure (IOP), although no ocular complications have been reported in normal, glaucomatous or postsurgical eyes. In this case report, we describe a 73-year-old female patient suffering a recurrent depressive disorder, who was admitted to acute psychiatric unit because a treatment-resistant major depressive episode (after an adequate trial of antidepressant drugs and transcranial magnetic stimulation) and clinical suspicion of visual delusions by her reference psychiatrist. The nonpsychiatric history consisted of hypertension, glaucoma and ulcerative colitis in treatment with azathioprine and mesalazine. After a careful examination in the emergency room, we consulted to ophthalmologist because miodesopsias and glaucoma history. The IOP was normal, but a bilateral posterior vitreous detachment (PVD) was identified. Because this entity is not an absolute contraindication for ECT, and there is scarce evidence, we informed the patient and her family. After that, and through informed consent, we decided to undergo ECT. After fourteen sessions, the patient could be discharged because significant clinical benefit and no ocular complications. Outpatient continuation ECT was indicated. Conclusions ECT can be a safe treatment choice in cases of PVD. Disclosure of interest The authors have not supplied their declaration of competing interest.
