Transcutaneous capnography is a noninvasive method useful for analysis of the behavioral tendency of transcutaneous CO 2 pressure (PtcCO 2 ) in patients undergoing polysomnography, to evaluate respiratory sleep disorders. Objective: Determine normative PtcCO 2 values in normal patients undergoing polysomnography. Method: One hundred seventy-nine patients who underwent polysomnography with simultaneous PtcCO 2 measurement were assessed by means of a transcutaneous capnograph (TCM4 series from Radiomiter). Results: The group classified as normal (N=53) presented a apnea/hypopnea index (AHI) ,5 events/per hour of sleep and their age groups varied between 7 and 76 years of age. Conclusion: Global mean values of PtcCO 2 in the normal group had a Gaussian distribution that varied between 33.1 and 50.0 mmHg (SD 4,363). Such findings allowed the establishment of normative PtcCO 2 values for normal individuals.

Terson's syndrome is characterized by the presence of a subarachnoid hemorrhage accompanied by retinal and vitreous hemorrhage leading to a not very favorable prognosis. We describe a case with a good outcome, probably because of a early diagnosis and medical intervention. We emphasize the routine optician's check up as very important in the evaluation of a prognosis in the cases of a suspect intracranial hemorrhage .
