RESUMO

PURPOSE: To assess the association of potential risk factors with early and late age-related macular degeneration (AMD) in the Thessaloniki Eye Study (TES) population Design: Population-based, cross-sectional study of subjects over age of 60 living in Thessaloniki, Greece Methods: Subjects without any AMD features and subjects with early and late AMD (neovascular AMD or geographic atrophy) were identified in the TES cohort using standardized procedures and masked grading of stereo color fundus photos. Demographic, lifestyle, systemic and other ophthalmic covariates were also collected during a detailed examination process. Their association with AMD was investigated using univariate and multivariate adjusted logistic regression models. RESULTS: Among the 2108 participants with gradable photos, the grading process identified 1204 subjects with no AMD, 848 subjects with early AMD, and 56 subjects with late AMD (24 with geographic atrophy and 32 with neovascular AMD). In multivariate analysis, compared to no AMD, late AMD was positively associated with older age (OR:1.16; 95%CI:1.10-1.22 per year of age), current smoking (smoking vs. never smoking, OR:2.34; 95%CI:1.12-4.90), prior cataract surgery (cataract surgery vs. no cataract surgery OR:2.06; 95%CI:0.96-4.40), marital status (divorced/separated vs. married, OR:3.10; 95%CI:1.08-8.93) and with 60% lower odds when sleeping in the afternoon (yes vs. no, OR:0.40; 95%CI:0.22-0.72). Early AMD was positively associated with older age (OR: 1.03; 95%CI:1.01-1.05 per year of age) and negatively with higher pulse pressure (OR:0.99; 95%CI:0.98-0.99 per mmHg). CONCLUSIONS: In TES, apart for well-known risk factors for AMD like age, smoking, and cataract surgery, two novel behavioral risk factors for prevalent late AMD were suggested. Sleeping in the afternoon was associated with 60% decreased odds for late AMD and 67% decreased odds for neovascular AMD. Being divorced/separated compared to married was associated with 3-fold higher odds for late AMD. Large longitudinal population-based studies will be necessary to further establish the potential late AMD risk effects of these two novel factors, to demonstrate potential implications of underlying pathogenetic mechanisms, and to explore preventive measures and therapeutic targets.

RESUMO

Prescribing medical therapy for the treatment of glaucoma can be a complex process since many parameters should be taken into consideration regarding its achievements and limits. Today, a variety of options, including multiple drug classes and multiple agents within classes, are available to the clinician, but caution should be given to their side effects and contraindications. Glaucoma patients with preexisting ocular surface disease should be treated with caution, and preferably with preservative-free formulations, as there is an increased risk for symptom deterioration. The development and use of fixed-combination therapies has reduced the preservative-related side effects that threaten patient adherence and has minimized the washout effect of multiple instillations. Adherence to medical treatment is not only crucial to its efficacy but also to its cost-effectiveness. Further factors to consider are that there are patients who are nonresponders to treatment, and also that the target intraocular pressure (IOP) cannot be reached in all patients, regardless of the response to treatment. The progression of damage can occur even under maximum medical treatment or maximally tolerated medical treatment, and regardless of whether low IOP levels are reached. Furthermore, there is some conflict between medical treatment and quality of life due to long-term everyday use and to side effects of treatment. New molecules and new delivery systems are being investigated to open new horizons in glaucoma management. Although the general rule is to initiate glaucoma management with medical treatment, the limits of medical therapy should be considered to identify those patients in need of surgical management.

RESUMO

PURPOSE: To evaluate the effect of anti-VEGF treatment on pigment epithelial detachment (PED) secondary to the exudative type of age-related macular degeneration (AMD). METHODS: Retrospective analysis of 30 eyes (28 patients) with exudative AMD accompanied by PED (receiving anti-VEGF injections). Alterations of the PED morphology were qualitatively assessed with optical coherence tomography (OCT). Changes in best-corrected visual acuity (BCVA) and number of injections were compared to 30 control eyes (30 patients) exhibiting exudative AMD without PED. RESULTS: Mean follow-up was 19.8 months. Changes of the extent of PED were as follows: unchanged: 11 eyes (36.7%); reduced: 12 (40%); significantly reduced: 7 (23.3%). Mean paired difference in BCVA was -0.08 logMAR (p = 0.46) and in the number of injections was 2.1 injections (p = 0.04). CONCLUSIONS: A substantial number of the studied patients showed reduction of the extent of the PED after anti-VEGF treatment. The PED group required a higher number of injections.
