A Case of Decompression Retinopathy After Resolution of Acute Primary Angle-Closure Glaucoma

ABSTRACT

PURPOSE:To report a case of ocular decompression retinopathy after resolution of acute primary angle closure (APAC) subsequent to medical treatment and laser peripheral iridotomy (LPI). CASE SUMMARY: A patient presented with APAC of the right eye with markedly elevated intraocular pressure (IOP) and a LPI was done after lowering the IOP with medical treatment. On presentation, visual acuity was 0.3 in the right eye (OD) and IOP was 74 mmHg OD. Two hours after medical treatment IOP was found to be 16 mmHg OD. Ten hours after resolution of the acute attack, the patient's visual acuity was 0.2 OD and IOP was 11 mmHg OD. LPI was subsequently performed in the right eye. The post-LPI IOP was 10 mmHg and the patient complained of visual disturbance and floaters OD. Three days after LPI the IOP was normal but her visual acuity had decreased to counting fingers OD. In addition, scattered retinal hemorrhages including alarge pre-retinal hemorrhage on the macula were found upon dilated funduscopic examination. After three months the retinal hemorrhage had been absorbed and her visual acuity was 0.7 OD. CONCLUSIONS: Decompression retinopathy can develop in the posterior pole of the retina in patients with APAC after medical treatment and LPI.
