Ocular implants-methods of ocular reconstruction following radical surgical interventions.

The main motivation of an ocular-orbital reconstruction after a radical surgical intervention (evisceration, enucleation) is represented by the psychological and socio-economic impact of such interventions on life conditions of patients. The current methods for ocular prosthesis are based on a new concept, which is nanotechnology, and its main objectives represent the reconstruction of the remaining orbital volume, reduction of postoperative complications and maintaining a satisfactory esthetical aspect. This review will discuss the numerous types of ocular implants that have been used throughout history as well as the most recent methods used by ophthalmic surgeons, also taking into consideration the advantages and disadvantages from a cosmetic, functional and short and long term postoperative complications point of view.

Update on retinal vascular caliber.

Retinal vessels are the only blood vessels that can be viewed directly, in vivo, repetitively and non-invasively. Retinal vessel caliber is influenced by physiological (age, sex, race, blood pressure, blood glucose, body mass index) and pathological (atherosclerosis, dyslipidemia, smoking) determinants. There are studies on large population groups that demonstrate the associations between retinal vasculature and subclinical or clinical changes in systemic diseases (hypertension, diabetes, stroke, renal or cardiac diseases).
