Endophthalmitis is a rare, but very severe form of ocular inflamation. Inflammatory process involves all types of intraocular liquids and tissues. It is usually accompanied by lowered of visual acuity, pain and notable inflammation of anterior segment. Endophthalmitis is most commonly diagnosed as a result of ocular surgery; however its etiology can be of a different background. Due to severe complications, fast diagnosis and optimal treatment are required. The aim of this article is to systematize types of endophthalmitis and indicate the best treatment possible for each of them.

Zapalenie wnętrza gałki ocznej, zwane również endoftalmitem, jest rzadkim, ale bardzo groźnym w skutkach stanem okulistycznym. Proces zapalny obejmuje zarówno płyny, jak i tkanki wewnątrzgałkowe. Zwykle obserwuje się spadek ostrości wzroku, ból oraz wyraźny stan zapalny przedniego odcinka oka. Najczęściej występuje po zabiegach okulistycznych, choć może on mieć również inne podłoże. Ze względu na możliwe ciężkie powikłania konieczne jest podjęcie szybkiej diagnostyki i wdrożenie najbardziej optymalnego leczenia. Artykuł ten ma na celu usystematyzowanie typów zapaleń wnętrza gałki ocznej i wskazanie najtrafniejszej metody leczenia dla każdego z nich.

Purpose: Hyperglycemia and increased concentrations of elastin degradation products (EDPs) are common findings in patients with diabetes, atherosclerosis and hypertension. The aim of this study was to assess the influence of high glucose, EDPs and atorvastatin on MMP-1, MMP-2, MMP-9 and TIMP1-3 gene expression in human retinal pigment epithelial cells (HRPE) in vitro. Method: HRPE were cultured for 24 hours with the substances being tested (glucose, EDPs), alone or in combination. Additionally, the cells were treated with atorvastatin in two different concentrations (1 or 10 μM). After incubation, total cellular RNA was extracted and used for gene expression evaluation. Gene expression was measured using the real-time RT-PCR technique. Results: Glucose, EDPs and atorvastatin had no impact on TIMP-1 and TIMP-3 expression. HRPE cells treated with glucose or EDPs with the addition of atorvastatin had a statistically significant decrease of TIMP-2 expression; glucose alone decreased MMP-1 expression. Atorvastatin decreased expression of all assessed genes, except TIMP-1 and TIMP-3 in a dose-dependent manner. Conclusions: Our results confirm the importance of MMPs and TIMPs in retinal vascular biology. Atorvastatin-induced MMPs gene expression can deeply affect extracellular matrix turnover, which may play an important role in the progression of ocular diseases.

The aim of the present study was to investigate the association of age related macular degeneration (AMD) risk with some aspects of iron homeostasis: iron concentration in serum, level of soluble transferrin receptor (sTfR), and transferrin receptor (TFRC) genetic variability. Four hundred and ninety one AMD patients and 171 controls were enrolled in the study. Restriction fragment length polymorphism PCR was employed to genotype polymorphisms of the TFRC gene, and colorimetric assays were used to determine the level of iron and sTfR. Multiple logistic regression was applied for all genotype/allele-related analyses and the ANOVA test for iron and sTfR serum level comparison. We found that the genotypes and alleles of the c.-253G > A polymorphism of the TFRC gene were associated with AMD risk and this association was modulated by smoking status, AMD family history, living environment (rural/urban), body mass index and age. The levels of sTfR was higher in AMD patients than controls, whereas concentrations of iron did not differ in these two groups. No association was found between AMD occurrence and the p.Gly142Ser polymorphism of the TRFC gene. The results obtained suggest that transferrin receptor and variability of its gene may influence AMD risk.
