ULTRASOUND EXAMINATION OF THE ORBIT IN PATIENTS WITH THYROIDASSOCIATED ORBITOPATHY - EXAMINATION GUIDE AND RECOMMENDATIONS FOR EVERYDAY PRACTICE. A REVIEW.

The purpose of this study is to present the possibilities and benefits of ultrasonography (US) of the orbit in the diagnosis and treatment of thyroidassociated orbitopathy (TAO). Methods: US examination of the orbit is an essential addition to clinical and laboratory examination in TAO patients. Nevertheless, it is often neglected in clinical practice or indicated with delay. Based on previously published studies and our experience with the diagnosis and treatment of TAO patients, we aim to highlight the clear benefit of US examination of the orbit and oculomotor muscles, not only for correct TAO diagnosis but also in the monitoring of the disease over time. However, knowledge of the drawbacks and limitations of this method is also essential, as we shall point out. It is always necessary to remember that US examination must be evaluated in connection with the clinical findings. A detailed recommendation for US examination of the extraocular muscles and the orbit based on our experiences with diagnosing and treating TAO patients in daily practice is also included. Conclusion: According to our experience, US examination of the orbit is an excellent and irreplaceable tool for timely TAO diagnosis and further disease monitoring. However, considerable examiner experience and detailed knowledge of the clinical and ultrasound manifestations of TAO are essential.

Computed tomography and magnetic resonance imaging of the orbit in the diagnosis and treatment of thyroid-associated orbitopathy - experience from practice. A Review.

The purpose is to acquaint readers with the contribution of imaging methods (IMs) of the orbit, specifically computed tomography (CT) and magnetic resonance imaging (MRI), in the diagnosis of thyroid-associated orbitopathy (TAO). Methods: IMs of the orbit are an indispensable accessory in the clinical and laboratory examination of TAO patients. The most frequently used and probably most accessible method is an ultrasound examination of the orbit (US), which, however, has a number of limitations. Other methods are CT and MRI. Based on the published knowledge implemented in our practice and several years of experience with the diagnosis and treatment of TAO patients, we would like to point out the benefits of CT and MRI in the given indications: visualisation of the extraocular muscles, assessment of disease activity, diagnosis of dysthyroid optic neuropathy and differential diagnosis of other pathologies in the orbit. Our recommendation for an ideal MRI protocol for disease activity evaluation is also included.  Conclusion: IMs play an irreplaceable role not only in the early diagnosis of TAO, but also in the monitoring of the disease and the response to the applied treatment. When choosing a suitable IM for this diagnosis, a number of factors must always be taken into account; not only availability, cost and burden for the patient, but especially the sensitivity and specificity of the given method for the diagnosis of TAO.

OCULAR COMPLICATIONS OF DIABETES MELLITUS IN PREGNANCY - CASE REPORT.

Pregnancy is associated with increased risk of progression of diabetic retinopathy (DR), the greatest risk of worsening occurs during the second trimester of pregnancy and persists as long as one year after the childbirth. The risk factors include duration of the diabetes, insufficient metabolic control, severity of DR at the time of conception and presence of coexisting vascular disease, such as arterial hypertension, and pregnancy itself. The recommendations for retinopathy screening in pregnancy vary significantly. A dilated fundus exam should be done in the beginning of pregnancy, the next follow-up throughout pregnancy depends on the severity of ocular findings. The cooperation of multi-disciplinary team consisting of ophthalmologist, obstetrition and endocrinologist is essential to provide the best health care. The authors present a case report of a pregnant woman with type 1 diabetes mellitus (DM), who had a progression of DR and diabetic macular edema (DME) in both eyes during pregnancy. She has had DM for 24 years and has been treated with insulin. The patient was examined at the 23rd week of the second pregnancy (first pregnancy was terminated because of missed miscarriage). The diagnosis of advanced proliferative DR and advanced DME in both eyes was made so we performed panretinal laser photocoagulation of the retina of both eyes. Despite that the ocular findings got worse and we found vitreous haemorrhage in the left eye. We performed pars plana vitrectomy (PPV) of the left eye at the 28th week of pregnancy, nevertheless the DME got worse in both eyes, so we recommended to terminate the pregnancy at the 31st week because of the risk of loss of vision. The visual acuity of the left eye improved, but suddenly there was vitreous haemorrhage in the right eye after the delivery. We indicated PPV of the right eye, the outcome of the surgery was satisfying. We still take care about this patient.
