Chlorthalidone-induced acute bilateral angle-closure glaucoma – An atypical clinical presentation
Parul Sharma, Garima Satija, Svati BansalWe report a case of chlorthalidone-induced bilateral secondary angle-closure glaucoma presenting with atypical features of markedly high intraocular pressure (IOP) and a quiet eye with no congestion in a hypermetropic patient. The patient had a shallow anterior chamber on slit-lamp examination, ciliochoroidal effusion on ultrasonography, and showed rapid anatomical and functional recovery following discontinuation of chlorthalidone and medical management. This case is unique due to the absence of myopic shift, presence of a quiet eye, and markedly elevated IOP. The report adds to current literature by highlighting how in a short hypermetropic eye, even a small anterior movement of the iris lens diaphragm can cause very high IOP without inducing myopia.
