AIM: To improve the approach to pathogenetic treatment of diabetic retinopathy (DR) through early diagnosis and a new method for predicting disease progression. MATERIAL AND METHODS: The study enrolled 330 type 2 diabetes patients with DR (660 eyes), of whom women constituted 64.6%, men - 35.4%. The mean patient age was 62.3±2.3 years. Three groups were formed: the controls - 30 healthy volunteers (60 eyes) and 30 type 2 diabetes patients without ocular involvement (DR 0, 60 eyes); group 1 - 30 type 2 diabetes patients with DR I but no diabetic macular edema (DR I without DME, 60 eyes) that were treated with calcium dobesilate; group 2 - 240 type 2 diabetes patients, who had diabetic retinopathy of different stages (DR I, II, or III with DME, 480 eyes) and received laser retinal photocoagulation (LRP)...

PURPOSE OF REVIEW: Optical coherence tomography (OCT) has become an integral component of modern glaucoma practice. Utilizing color codes, OCT analysis has rendered glaucoma diagnosis and follow-up simpler and faster for the busy clinician. However, green labeling of OCT parameters suggesting normal values may confer a false sense of security, potentially leading to missed diagnoses of glaucoma and/or glaucoma progression. RECENT FINDINGS: Conditions in which OCT color coding may be falsely negative (i...

The study aim was to evaluate the efficacy of adalimumab (ADA) in a large series of Behçet's disease (BD)-related uveitis. We performed a multicenter retrospective observational study including 40 selected patients (66 eyes) receiving ADA. Clinical data were retrospectively analyzed at baseline, at 3 and 12 months of treatment. Primary end point was reduction of ocular inflammatory flares. Secondary end points were improvement of best corrected visual acuity (BCVA), reduction of macular thickness measured by optical coherence tomography (OCT), reduction in the occurrence of vasculitis assessed by fluorescein angiography (FA), and evaluation of statistically significant differences between patients treated with ADA monotherapy and those undergoing ADA plus DMARDs and in patients firstly treated with ADA compared to patients previously administered with other biologics; ADA steroid sparing effect was also evaluated...

Macular coloboma is a congenital defect of the retina and choroid in the macular region. It may appear due to an intrauterine inflammation or a developmental abnormality. Familial hypomagnesemia with hypercalciuria and nephrocalcinosis (FHHNC) is a result of malformation of the renal tubule. Its combination with ocular manifestations may be genetic, specifically in case of claudin-19 (CLDN-19) gene mutations. The combination of FHHNC and ocular manifestations is not always present in these patients. Optical coherence tomography (OCT) helps us diagnose this condition by allowing us to evaluate and confirm the absence of retina layers without histological examination...
