scholarly journals Intravitreal Ranibizumab Treatment and Treatment Regimens in Wet-Form (Neovascular) Age-Related Macular Degeneration

Age-related macular degeneration (AMD) is a chronic and progressive disease of the central retina that causes vision loss in people over 50 years of age. With an understanding of the role of VEGF in AMD, intravitreal anti-VEGF agents are used as the most important therapeutic tool in the management of AMD. In this review we try to discuss intravitreal ranibizumab treatment and treatment regimens in wet (neovascular) age-related macular degeneration.

Purpose. To report our experiences in patients with age-related macular degeneration (AMD) treated initially with intravitreal ranibizumab and then switched to bevacizumab. Methods. We retrospectively reviewed the records of 7 patients (7 eyes) who were treated with monthly injections of intravitreal ranibizumab and then switched to injections of bevacizumab (every 6 weeks) for six months. The best-corrected visual acuity measurements (BCVA) and optical coherence tomography (OCT) were performed at the baseline examination and then at each visit. The Wilcoxon signed-rank test was used for the statistical analysis. Results. Following three monthly ranibizumab treatments, there was no significant difference in the BCVA, while the foveal retinal thickness (FRT) significantly decreased (). Switching from ranibizumab to bevacizumab resulted in maintenance (57.2%) of the BCVA and a further decrease in the FRT () after 6 months. Conclusions. Switching to intravitreal bevacizumab may be effective in patients who wish to discontinue intravitreal ranibizumab treatment due to the high cost.

Age-related macular degeneration mainly affects the elderly and is one of the most common causes of rapidly progressive vision loss. Over more than 150 years of research, the scientific community has gone from understanding the macroscopic picture of the lesion, presumable identification of drusen as the main morphological manifestation of nosology, to detailed classifications and determine the role of genetic determinants in the etiopathogenesis of the disease — high specificity, the possibility of preventive analysis, and much unclear in the field of genetic diagnosis of eye diseases determine the accurate attention of specialized research groups to the early diagnosis using genetic analysis. The review article was aimed to systematize the information about possible links in the pathogenesis of age-related macular degeneration and identify potential polymorphisms that can initiate and modulate the activity of these links. During the study, we could find out five main mechanisms of damage to the vascular membrane of the eye itself, which are affected by single nucleotide polymorphisms. The hig­hest affinity was shown by genetic variants of separate sites of CFH (rs1061170), HTRA1 (rs11200638), TNF (rs1800629), VEGFA (rs2010963). Literature data obtained from foreign and national sources indexed by Scopus, Web of Science databases, in particular for the last 5 years, pay special attention to these areas as potential predictors or modifiers of pathological processes involved in the process of macular degeneration. Despite the large number of studies examining the predisposition, pathogenesis, diagnosis, and treatment of age-related macular degeneration to stop the spread of vision loss, only a few issues are understood thoroughly. Considering the successful cases of application of biological and gene therapy for the management of such patients, we see new horizons in the detailed study of molecular interactions that underlie the pathology. The review confirms the active role of polymorphisms in one of the most relevant pathological processes of the human eye.

Introduction: The results of intravitreal ranibizumab treatment for exsudative age-related macular degeneration have been favourable until this time. Aim: To evaluate the two-year functional and anatomic results of intravitreal ranibizumab treatment. Method: 46 patients (age: 75±9.1 years) were included in a prospective single center study. Treatment regimen was the following: monthly 0.5 mg ranibizumab was administered in the first 3 months, and later as required (pro re nata). The change of best corrected visual acuity and central retinal thickness was followed. Results: The visus change at the end of the follow-up time was not statistically significant compared to baseline (p = 0.760) and the at the end of the first year (p = 0.154). Central retinal thickness decreased significantly compared to baseline (p = 0.000001), but the change was not statistically significant compared to the end of the first year (p = 0.875). Conclusions: Patients with neovascular macular degeneration treated with intravitreal ranibizumab using pro re nata regimen have stable visus for long term, and the exsudation could be reduced efficiently.

Age-related macular degeneration (AMD) is a multifactorial disease that represents the most common cause of irreversible visual impairment among people over the age of 50 in Europe, the United States, and Australia, accounting for up to 50% of all cases of central blindness. Risk factors of AMD are heterogeneous, mainly including increasing age and different genetic predispositions, together with several environmental/epigenetic factors, that is, cigarette smoking, dietary habits, and phototoxic exposure. In the aging retina, free radicals and oxidized lipoproteins are considered to be major causes of tissue stress resulting in local triggers for parainflammation, a chronic status which contributes to initiation and/or progression of many human neurodegenerative diseases such as AMD. Experimental and clinical evidences strongly indicate the pathogenetic role of immunologic processes in AMD occurrence, consisting of production of inflammatory related molecules, recruitment of macrophages, complement activation, microglial activation and accumulation within those structures that compose an essential area of the retina known as macula lutea. This paper reviews some attractive aspects of the literature about the mechanisms of inflammation in AMD, especially focusing on those findings or arguments more directly translatable to improve the clinical management of patients with AMD and to prevent the severe vision loss caused by this disease.
