Hello! I´m Honassys Rocha, Clinica do Olho medical director. Today is “Ask the doctor day!” And I´ll talk about high ocular pressure and glaucoma. Use the opening sequence, to give us a like and subscribe to the channel. Diná Brandão asked us through YouTube: Good night, doctor! Is it possible to a person has a high ocular pressure and doesn´t have glaucoma? Diná, thank you very much for your question. It is very frequent in the doctor´s office. Indeed, it may happen a condition that the patient has a high ocular pressure, but doesn´t have glaucoma. We need to define high ocular pressure, which is when the pressure is 22 or higher. Normal people with normal ocular pressure, have it until 21mmHg. 22 or higher is considered ocular hypertension. So, dealing with a patient with high ocular pressure, doesn´t mean this patient has glaucoma. I like to look at statistics and the statistic risk gets important when it get over 25mmHg. But it is not that simple. We have to start an investigation to better understand why is this pressure high. The first complementary exam we need to do in this patient is the ultrasound pachymetry. This exam will show the corneal thickness of the patient So if the patient has a thicker cornea, the resistance of this cornea against to the equipment will be increased and the pressures will be higher falsely measured. On the other hand there is a thin cornea, dangerously the equipment reads a low ocular pressure. I made a specific video about corneal thickness and pressure mesure. You can find the link of this video on the video description. Another exam that I understand it´s fundamental with these people who have isolated high ocular pressure or repeated high measure, is the water drinking test or a daily intraocular pressure curve, the last one is usually measured four times in one day. Particularly I have predilection for water drinking test and I can make a special video about this matter. One last thing to close this basic investigation of a person who has high pressure peaks is the camerular sinus investigation, which is the eye drainage area. Sometimes this camerular sinus can be narrow-angle and provoke some closures. These little closures provoke intra ocular transitory elevation. I really like two exams to help this investigation: Gonioscopy, a classic exam that show us the drainage area and the second exam is Optical Coherence Tomography (OCT) where, in a dark room, the equipment shows, with images, how is the drainage angle condition near patient reality, while he/se is at nigh at home, for example, or sleeping. This way we can understand how does the pressure work, identify the peak and in some cases, above all that cases we find pressures of 25mmHg or more, we start thinking about indicating some treatment, be it with eye drops or laser. If you have any question about glaucoma as well as another eye diseases I suggest you to leave it on our site clinicadoolho.med.br The vision is the most important human being sense. Best regards ans see you next video.
