Abstract Objective To evaluate retinal oxygen metabolism by retinal oximetry for ocular and CNS diseases in a cross-sectional study of sarcoidosis. Methods Overall 201 eyes from 103 biopsy-verified sarcoidosis patients were included and divided into four groups depending on the organ affection: (i) sarcoidosis without ocular or CNS affection, (ii) ocular sarcoidosis, (iii) CNS sarcoidosis, and (iv) combined ocular and CNS sarcoidosis. Retinal oximetry was obtained and analysed, with the mean retinal arteriolar and venular saturation as well as arteriovenous difference as principal outcomes. Comparison between groups was done in a multi linear regression model adjusted for age, sex, duration of sarcoidosis, best corrected visual acuity and retinal oximetry quality. Results Mean (s.d.) age was 50.5 (13.4) (95% CI: 47.9, 53.1) years and 52.2% were males. Eyes of the combined Ocular/CNS group had a higher retinal arteriovenous difference than eyes of the Non-ocular/no-CNS group (42.1% vs 37.7%, P = 0.012) but did not differ between other groups. Eyes in the four groups (Non-ocular/no-CNS, Ocular, CNS and Ocular/CNS) did not differ according to retinal arterial (94.5%, 93.5%, 93.5% and 94.5%, respectively) or venular (57.5%, 56.4%, 55.0% and 52.5%, respectively) oxygen saturation. Conclusions The results of this study suggest that eyes of sarcoidosis patients with combined ocular and CNS affection have an altered oxygen metabolism indicating a subclinical eye affection that is not recognized by conventional screening methods.

Abstract To test the hypothesis that microvascular obstruction to blood flow at the level of the arteriole may be significant in individuals with sickle cell anemia, the ophthalmologic effects of orally administered nifedipine were monitored in 11 steady-state patients. Three patients with evidence of acute peripheral retinal arteriolar occlusion displayed a prompt reperfusion of the involved segment. Two other patients showed fading of retroequatorial red retinal lesions. Color vision performance was improved in six of the nine patients tested. The majority of patients also demonstrated a significant decrease in the amount of blanching of the conjunctiva which reflects improved blood flow to this frequently involved area. Such improvements were not observable in a control group of untreated stable sickle cell subjects. These findings support the hypothesis that inappropriate vasoconstriction or frank vasospasm may be a significant factor in the pathogenesis of the microvascular lesions of sickle cell disease and, further, that selective microvascular entrapment inhibition may offer an additional strategy to the management of this disorder. We believe a larger, placebo-controlled study with nifedipine and similar agents is warranted.

Purpose. We report a case of hypertensive choroidopathy with bilateral serous retinal detachments.Patient. A 50-year-old man underwent bilateral serous retinal detachments. Retinal arteriolar narrowing, vascular tortuosity, and arteriovenous nicking were identified in both eyes. The blood pressure was 206/125 mmHg. The patient was diagnosed with bilateral hypertensive choroidopathy and treated with oral antihypertensive treatment.Results and discussion. One month after antihypertensive treatment, the serous retinal detachments resolved and the visual acuity improved. A patient with those findings should be considered as having hypertensive choroidopathy and treated as soon as possible.

Purpose. To present a clinical case of development of retinal macroaneurysm after carotid endarterectomy (CE) in patient with chronic ischemic retinopathy (CIR) associated with hemodynamically significant stenosis of the internal carotid artery (ICA). Material and methods. Patient R., 74 years old, diagnosed with CIR of the 1st degree of severity of the right eye. In addition to standard ophthalmic examination methods, Doppler ultrasound with registration of blood flow in the orbital artery and spiral computed tomography of the ICA were performed. Results. Panretinal photocoagulation (PRP) of the retina led to obliteration of the retinal macroaneurysm, resorption of intraretinal hemorrhages, and stabilization of the course of CIR after CE of the ICA. Conclusion. The appearance of retinal macroaneurysm and intraretinal hemorrhages after CE in patient with CIR associated with hemodynamically significant ICA stenosis can be regarded as reperfusion complications after restoration of blood flow in the orbital artery, which requires timely retinal PRP of the retina. Key words: chronic ischemic retinopathy, retinal macroaneurysm, internal carotid artery, carotid endarterectomy.
