Abstract (EN): Purpose: To describe a case of hypotony maculopathy following anti-VEGF intravitreal injection (IVI) in a patient with pseudox-anthoma elasticum (PE).Methods: Clinical case report.Results: A 52-year-old male complained of right eye (OD) vision loss 2 days after an uncomplicated anti-VEGF IVI for the treatment of choroidal neovascularization secondary to angioid streaks. Relevant medical history included PE, pathologic myopia, and a previous pars plana vitrectomy (PPV) due to a retinal detachment. OD best-corrected visual acuity (BCVA) dropped from 6/ 12 to 6/18 after the IVI. Intraocular pressure (IOP) was 3 mmHg and chorioretinal folds were evident in the posterior pole. Topical dexamethasone and atropine were prescribed, and full recovery was noticed after 3 days. Four months later, the patient developed a new episode of vision loss after another IVI. His BCVA was counting fingers, IOP was 2mmHg, and more noticeable chorioretinal folds were found. This time, an open scleral wound at the injection site was evident and a scleral suture was necessary. Once again, the patient recovered well.Conclusion: Hypotony maculopathy following intravitreal injection is a rare condition. However, the described patient presented several conditions which could be related with poor scleral wound closure: intrinsic scleral fragility due to myopia and pseudox-anthoma elasticum; repeated IVI procedures; and absence of vitreous in the posterior segment due to prior vitrectomy. Despite the good outcome, hypotony maculopathy may be a sight-threatening condition, and special attention is necessary for specific patients with risk factors.
