Purpose:To evaluate the change of choroidal thickness and intraocular pressure (IOP) as a result of hemodialysis with chronic renal failure patients. In addition, the correlation between the change of choroidal thickness and IOP were evaluated. Methods: A total of 48 eyes of 48 chronic renal failure patients undergoing hemodialysis were included in the present study. IOP, blood pressure (systolic and diastolic), serum osmolality, central corneal thickness (CCT), and choroidal thickness were measured before and after hemodialysis. Choroidal thickness was measured using spectral domain ocular coherence tomography (SD-OCT). Results: After hemodialysis, IOP significantly decreased from 14.9 ± 2.3 mm Hg to 14.3 ± 2.1 mm Hg (p < 0.001) and choroidal thickness significantly decreased from 352.2 ± 31.6 μm to 306.6 ± 29.0 μm (p < 0.001). The other factors that significantly decreased after hemodialysis included serum osmolality (p < 0.001) and blood pressure (p < 0.001) except CCT (p = 0.285). There was a positive correlation between changes in IOP and choroidal thickness after hemodialysis (r = 0.319, p = 0.027). Conclusions: Decreased choroidal volume and thickness due to fluid loss may be involved in the mechanism of decreased IOP during hemodialysis. J Korean Ophthalmol Soc 2013;54(5):752-756
(Fig. 1B) 빛간섭단층촬영상 우안 황반부종 과 함께 감각신경망막층의 박리 소견이 관찰되었다 (Fig. 2).첫 방문 후 2번의 경과 관찰이 이루어졌으며, 수상 후 1 개월째 우안 최대 교정시력은 안전수지 50 cm이었으며, 안 저 검사상 황반부위에 광범위한 망막하 삼출물 소견과 망 막부종이 있었다 (Fig. 3A). 수상 3년 후 본원 마지막 내원 시 우안 최대 교정시력은 20/600으로 수상 직후에 비해 약 간의 호전이 있었으며, 안저검사상 황반부에 반흔 및 망막 색소상피의 탈색소 병변이 관찰되었다 (Fig. 3B).
