Abstract
Purpose
Acute angle-closure is a rare manifestation of choroidal metastasis. We reported a case of choroidal metastasis from lung adenocarcinoma presenting with unilateral acute angle-closure attacks relieved with radiotherapy after failed conventional medical and laser treatments. This represented the first detailed report of treatments of secondary acute angle-closure attacks in patients with choroidal metastasis
Case description
A 69-year-old female without ocular history was diagnosed with metastatic lung adenocarcinoma. One month later, she complained of blurred vision and pain in the right eye that lasted 2 days. IOP was 58 mmHg and best-corrected visual acuity (BCVA) was counting finger in the right eye. Slit-lamp examination revealed corneal edema with ciliary congestion, extremely shallow anterior chamber both centrally and peripherally, mid-dilated pupil and moderate cataract in the right eye. While the left eye was normal. B-scan ultrasound and orbital computed tomography showed an appositional choroidal detachment with an underlying choroidal thickening suggesting choroidal metastasis in the right eye. There was limited effect of medical and laser therapy. IOP was 9 mmHg in the right eye after two months of palliative external beam radiotherapy in the right orbit. BCVA was hand motion in the right eye. Slit lamp examination revealed clear cornea, deep anterior chamber in the right eye. Regression of choroidal detachment and choroidal metastasis in the right eye were observed in B-scan ultrasound.
Conclusion
This case demonstrated that patient with secondary acute angle-closure attacks from large bullous choroidal detachment related to choroidal metastasis could only be successfully treated with radiotherapy as both medical and laser therapy might not be capable of breaking angle-closure attacks.
