Localized Serous Retinal Detachment of Macula as a Marker of Malignant Hypertension.

The association between serous retinal detachment of macula (SRD) in hypertensive retinopathy (HTR) and malignant hypertension has been reported. This cross-sectional study included 14 consecutive patients on treatment for hypertension, who were referred for ophthalmic evaluation and were found to have macular SRD, documented by optical coherence tomography. All underwent systemic evaluation for hypertensive status and to rule out other associated/similar diseases such as diabetes, coagulopathies, lupus etc. The mean age of the patients was 44.35 +/- 15.5 years; the mean best-corrected visual acuity was 6/12. All had grade 3-4 HTR; 10 patients had bilaterally symmetrical retinopathy (grade 3 or 4); 4 had asymmetric fundus changes. Systemically, every patient was found to have malignant hypertension. The mean systolic and diastolic pressures were 208.57 +/- 32.78 and 117.86 +/- 14.2 mm Hg, respectively. SRD predicted malignant hypertension more consistently than papilledema (P = .0132). The presence of macular SRD in a hypertensive patient may serve as an indicator of malignant hypertension.
