Abstract:
Purpose: Multicentric osteolysis nodulosis and arthropathy (MONA) syndrome is a rare autosomal recessive skeletal dysplasia. Caused by mutations in the matrix metalloproteinase 2 (MMP2) gene on chromosome 16q12, this syndrome has infrequently been associated with ophthalmic manifestations. Corneal opacities have been reported but not described or documented in detail. Methods: Complete ophthalmologic examination and multimodal anterior segment imaging were used to characterize the corneal findings in a patient with MONA syndrome. Results: A 19-year-old man with MONA syndrome was referred for a

Abstract:
A 65-year-old man presented with bilateral, painless, progressive blurring of vision over 9 years. Slit-lamp examination revealed bilateral subepithelial corneal opacities in clusters located at the mid-periphery. Anterior segment optical coherence tomography, in vivo confocal microscopy (IVCM), serum protein electrophoresis, and molecular genetic testing were performed to evaluate the cause of corneal opacities. Anterior segment optical coherence tomography revealed a band-like, hyperreflective lesion in the Bowman layer and anterior stroma of both corneas. IVCM revealed hyperreflective depos

This paper presents the structure and diseases of the cornea pathology leading to childhood blindness and visual impairment in different regions of the world. Epidemiology of corneal opacities in children examined in historical perspective, taking into account the socio-economic development of society. In economically developed European countries and America, the main cause of corneal opacities in children are congenital malformations of the eye anterior segment, in developing countries, the leading cause of corneal blindness occupy inflammatory corneal opacity (due to previous infectious kera

Abstract:
Bilateral Fuchs uveitis associated with vitreous infiltration and posterior segment involvement requires a thorough diagnostic evaluation. The lack of well-defined diagnostic criteria makes identification of this entity difficult. The aim of this case report was to present the characteristics of a patient with atypical Fuchs uveitis and the procedures needed to rule out the differential diagnosis with specific attention to the utility of in vivo confocal microscopy (IVCM).

The purpose of the study was to explore the possibilities of femtosecond laser-assisted anterior lamellar keratoplasty in patients with corneal opacities of various etiology. Materials and Methods. Femtosecond laser-assisted anterior lamellar keratoplasty (FALK) performed in 8 patients (4 males, 4 females) with superficial corneal opacities at the age from 16 to 20 years. Etiology of corneal opacities: in 3 cases - keratitis of unknown etiology, 2 - herpetic keratitis, 2 - burns, 1 - ulcer.

Purpose. To evaluate the surgical outcomes and visual results after penetrating keratoplasty for congenital unilateral corneal opacities in Peters anomaly. Methods. This was a retrospective study of 14 children who underwent keratoplasty for a unilateral Peters anomaly between 1999 and 2009. All patients received a topical treatment of cyclosporine and corticosteroids. Suture ablation was performed between the first and second postoperative month and all patients had spectacle correction and amblyopia treatment.

Abstract:
The 2019 coronavirus disease (COVID-19) pandemic is affecting millions of people worldwide. Chest high-resolution computed tomography (HRCT) is commonly used as a diagnostic test for suspected COVID-19; however, despite numerous attempts, there is no single scoring system that is widely accepted and used in clinical practice to estimate the probability of SARS-CoV-2 pneumonia. The aim of this single-center retrospective study is to develop a radiological score to predict the probability of COVID-19 with HRCT.
