Serum vitamin D level alterations in retinal vascular occlusions.

Aim: To evaluate serum vitamin D levels in sub-types of retinal vascular occlusions and compare the levels in ischemic and non-ischemic presentations.

Methods: This study included 50 patients of retinal vascular occlusions comprising central retinal vein occlusion, branch retinal vein occlusion, central retinal artery occlusion, branch retinal artery occlusion (study group) diagnosed on basis of clinical characteristics as well as investigations and an age and gender-matched healthy control group (control group). The study group was further classified into ischemic and non-ischemic subtypes and serum vitamin D levels were analysed and compared.

Association of serum vitamin D levels with clinical spectrum of central serous chorioretinopathy patients of Indian origin.

Background: Vitamin D, a fat-soluble prohormone has been implicated in various ophthalmological diseases such as ocular inflammation, glaucoma, diabetic retinopathy and ocular angiogenesis. Many studies have shown effect of vitamin D on oxidative stress, angiogenesis and retinal circulation. However, there is definitive lack in published literature on effect of vitamin D on central serous chorioretinopathy especially in view of various epidemiological studies reporting risk of vitamin deficiency in up to 40% adult population.

Three-dimensional printing in the field of oral and maxillofacial surgery.

Advanced imaging techniques and modalities coupled with computer-assisted surgical planning and simulation has been in use in the field of medicine. However, it is worth noting that it is now being frequently used for the evaluation and exploration of the craniofacial structures. It had gained ingress in the planning as well as forecasting of the surgical outcomes of oral and maxillofacial surgical interventions.
