Purpose To report a case of recurrent hypotony and exudative choroidal detachment in a patient with pseudoexfoliation glaucoma following the use of a topical preservative-free prostaglandin-timolol fixed combination eye drop. Case summary A 74-year-old diabetic patient with a history of trabeculectomy for pseudoexfoliation glaucoma presented with conjunctival hyperemia, ocular pain, and blurred vision 3 months after using a preservative free prostaglandin-timolol fixed combination. Intraocular pressure (IOP) was markedly reduced to 6 mmHg and fundus examination revealed severe exudative choroidal detachment involving three quadrants. Treatment with oral and topical corticosteroids, cycloplegics, and non-steroidal anti-inflammatory drugs normalized his IOP to 15 mmHg and resolved the detachment within 3 weeks. Two weeks later, the patient inadvertently reused the same medication mistaking it for artificial tears. Symptoms recurred the following day with his IOP dropping to 2 mmHg and choroidal detachment affecting all four quadrants. Re-treatment led to full recovery within 3 weeks. Conclusions Choroidal detachment following use of combination therapy with a prostaglandin analog and an aqueous suppressant is a rare complication. Patients with pseudoexfoliation syndrome and diabetes may be particularly susceptible. Vigilant monitoring of IOP and fundus status is recommended when prescribing these agents to individuals with multiple risk factors.
