The role of estrogen in the development of glacoma tous optic neuropathy.

Klin Oczna 2016 Sep;117(4):275-277

Clinical research findings confirm that sex-based hormonal differences and hormone level fluctuations occurring in women over their entire lifespan play a significant role in the development of glaucomatous optic neuropathy. Nevertheless, many issues have not been addressed yet or have not been analyzed to the appropriate extent. Therefore, it is necessary to identify the hormones affecting the development and clinical course of the disease and quantify their effect, as well as to determine whether the hormone replacement therapy can support glaucoma treatment and ensure its success.

Experimental studies on medical treatments of retinal dystrophies with a particular focus on ABCA4 retinopathies.

Klin Oczna 2016 Aug;118(1):59-65

Retinal dystrophies are a group of hereditary diseases varying in clinical and etiological aspects. The most common central retinal dystrophy is Stargardt's disease, which is mainly caused by mutations in the ABCA4 gene. Dysfunction of the ABCA4 gene product leads to accumulation of toxic metabolites of the visual cycle and consequently to the loss of photoreceptors and surrounding retinal pigment epithelial cells.

Changes in the central nervous system of prematurely born children.

Klin Oczna 2016 Aug;118(1):55-58

Preterm birth adversely affects the maturation of the central nervous system, including the process of white matter myelination, still incomplete at this stage. Prematurity is also a risk factor for the future visual impairment. Decreased visual acuity in premature infants observed during their development, may be caused by both retinopathy of prematurity and the damage to the central nervous system. Read More
