Introduction: Hypertensive retinopathy is a condition characterized by a spectrum of retinal vascular signs in people with elevated blood pressure. This condition can be accompanied by exudative retinal detachment in hypertensive retinopathy grade IV. Furosemide is considered as a diuretic agent to force fluid absorption across the retinal epithelium. This is consistent with a model for ion transport in the isolated RPE, in which active furosemide-inhibitable transport of chloride from retina to choroid for a significant fraction of the short-circuit current.
Objectives: To report the efficacy of oral furosemide in patients with exudative retinal detachment due to hypertensive retinopathy-IV.
Case presentation: We reported two young patients, first patient with chronic kidney disease complained with decreased of visual acuity to 20/100 in the right and 20/200 in the left eye. The second patient with preeclampsia suddenly experienced bilateral visual loss to counting finger on both eyes. Those patients showed sub-retinal fluid, macular star and cotton wool spots in both retina. Macular edema was seen by optical coherence tomography (OCT) examination in both eyes. Both cases were diagnosed as hypertensive retinopathy grade IV with exudative retinal detachment. Oral furosemide 40 mg once a day was given. On the first patient visual acuity improve to 20/80 on both eyes and on the second patient visual acuity improve to 20/400 on both eyes. Ocular ultrasonography (USG) examination showed significant decrease of exudative retinal detachment with in the 17 days.
Conclusion: Furosemide is diuretic agent and might be effective in resolution of exudative retinal detachment followed by improvement of visual acuities in patient with hypertensive retinopathy grade IV.
