We evaluated the in vitro effects of the 1.3 u wavelength of a Nd:YAG laser using a fiberoptic delivery system, with or without sapphire tips on ocular tissue. Conjunctival and retinal adhesions were achieved best with a noncontact technique compared with a contact method.
We evaluated the effects of Nd:YAG laser energy directly applied to ocular tissue through a fiberoptic and a sapphire tip. All ocular tissue could be easily cut with the maximum 4 watts of energy. The coagulated borders extended 20 to 200 mu into the healthy tissue depending on the speed with which the cutting was performed.
Evaluation of ultraviolet B index (UVBI) and its impact on vitamin D synthesis is important. We observed the maximum UVBI between 11 am and 1 pm. There was no increase in serum 25(OH)D levels following sun exposure during winter as the UVBI was significantly low, emphasizing the need for vitamin D supplementation during these months. The amount of vitamin… (More)
Apocrine hidrocystomas are cysts resulting from obstruction of the apocrine sweat gland ducts. They are usually solitary and seen in the head and neck areas. Apocrine hidrocystomas are rarely seen in the orbit with very few adult cases published in literature until now.
