Dear Editor:

It was with great interest that we read ‘Terson syndrome and ocular ultrasound’, which appears to be a very interesting and instructive letter.

We agree with the authors that Terson syndrome is an underestimated and underdiagnosed disorder. Action protocols between departments should be created to ensure appropriate treatment and follow-up for these patients.

We also agree that ocular ultrasound is an important diagnostic tool in cases of retinal haemorrhage. However, the most important diagnostic tool in these cases is examination of the fundus with an ophtalmoscope, a simple and inexpensive technique that yields unambiguous results.

That being said, we adhere to the opinion expressed in the original article1 regarding the severity of the haemorrhage and the presence of Terson syndrome.

In our hospital, we systematically examine the fundus of the eye of all the patients who present cerebral haemorrhage, according to a series of protocols established together with the ICU and the anaesthesiology departments, where patients are initially treated.

We have spent 2 years adding data to a database so as to establish whether there is a significant relationship between haemorrhage severity and presence of retinal haemorrhage in this patient group.

At this time, we can cautiously state that we have established a significant relationship between the severity of the patient's condition and presence of a haemorrhage in the fundus of the eye.

One of our preliminary conclusions is that haemorrhage was more severe when Terson syndrome was also present, in most of the patients we have studied.

Doctors may find atypical cases that do not follow this paradigm, as we mentioned in the original article. However, these cases make up a small minority and they are not significant.

In any case, additional articles confirm the relationship between haemorrhage severity and presence of retinal haemorrhage. For example, Frizell et al.2 corroborated the results of earlier studies indicating that presence of Terson syndrome is related to subarachnoid haemorrhage severity. Pfausler et al.3 observed high mortality rates (90%) among patients with this syndrome.

Subarachnoid haemorrhages are the most frequent cause of sudden death due to cerebrovascular accident and a high percentage of patients with this haemorrhage die before receiving treatment. Symptoms vary in intensity, display different manifestations, and depend on several factors.

Based on the above, we believe it is necessary to create Terson syndrome screening protocols in conjunction with the ICU and anaesthesiology departments since that syndrome is very likely indicative of haemorrhage severity.
