A Case of Nephrotic Syndrome with Bilateral Serous Retinal Detachment and Shallow Anterior Chamber Associated with Ciliary Body Edema

Nephrotic syndrome is a disease that causes fluid retention in the body due to loss of protein in the blood, which can lead to serous retinal detachment (SRD) in the macula. We report a case of severe SRD in both eyes and angle closure due to ciliary body edema caused by nephrotic syndrome. A 57-year-old man was admitted to the Department of Nephrology in our hospital for a thorough examination of his generalized edema. He was diagnosed with nephrotic syndrome but proved to be refractory to steroid treatment. Due to distortion symptoms in both eyes on the 30th day of hospitalization, the patient was referred to our department. Best-corrected visual acuity (BCVA) was 0.8 in the right eye and 1.0 in the left eye. Slit lamp examination and anterior segmental optical coherence tomography (OCT) showed shallow anterior chambers in both eyes. Fundus and macular OCT demonstrated severe SRD in the posterior pole of both eyes. After observing the presence of hypoalbuminemia, we considered the possibility of SRD and angle closure due to ciliary edema that resulted from the leaks associated with the nephrotic syndrome. Thereafter, ocular findings improved in conjunction with systemic symptom improvements associated with ultrafiltration and low-density lipoprotein apheresis. On the 60th day of hospitalization, his BCVA improved to 1.2 in both eyes, SRD disappeared, and the anterior chamber depth normalized. This case demonstrates the importance of recognizing SRD and angle closure associated with ciliary body edema as complications linked with nephrotic syndrome
