Abstract

Purpose: To report a case of ciliary body metastasis with uncontrolled glaucoma that was successfully treated with micropulse transscleral laser therapy (MPTLT).

Observations: A case of a 44-year-old female with uncontrolled glaucoma secondary to ciliary body metastasis from pulmonary adenocarcinoma. Antiglaucoma medications, intravitreal ranibizumab injection and local radiotherapy were ineffective in reducing her intraocular pressure (IOP) and ocular pain. MPTLT using a power setting of 2,000 mW, 31.3% duty cycle, and 140 seconds over 180 degrees demonstrated favorable IOP reduction (from 31 to 8 mmHg) on the first postoperative day without either ocular pain or postoperative complications. IOP remained controlled until she died from hemoperitoneum 18 days after hospital discharge.

Conclusions and importance: MPTLT can be a safe and effective procedure for IOP control in intraocular metastasis patients with uncontrolled glaucoma.
