Intraocular pressure reduction and vitreous mass: Influence of retrobulbar anaesthesia and acetazolamide.
Recent studies have evaluated many methods of reducing vitreous mass and minimizing vitreous loss at lens extraction (Robbins and Galin, I969; Robbins, Blumenthal, and Galin, I970; Galin, Robbins, and Obstbaum, 1970). In the rabbit, it is clear that hyperosmolar solutions are effective, while digital massage is not (Obstbaum, Robbins, Best, and Galin, 1970). It has been accepted that correctly-...
متن کاملIntraocular pressure, retrobulbar anaesthesia and digital ocular massage.
OBJECTIVES To determine the degree of intraocular pressure (IOP) rise following retrobulbar anaesthetic injection as well as the optimal time required for the return of the IOP to the pre-injection level following ocular massage. MATERIALS AND METHODS Using the Perkins hand-held tonometer, the IOP of consecutive adult patients were measured in the operating room before local anaesthetic (3 ml...
متن کاملEffect of hypercapnea and hyperventilation on human intraocular pressure general anaesthesia following acetazolamide administration.
The changes in intraocular pressure due to blood pH, PCO2, and PO2 alterations induced by hyperventilation and hypercapnea in man undergoing routine general anaesthesia were studied. It was shown that hypercapnea produces elevation of intraocular pressure, while hyperventilation lowers it. Acetazolamide pretreatment did not alter these IOP responses to PCO2, PO2, and blood pH changes.
متن کاملIntraocular pressure variation following retrobulbar anaesthesia among the different sex, age and ethnic groups in Malaysia.
A total of 114 patients (48 Chinese, 34 Malay and 32 Indian) undergoing extracapsular cataract extraction (ECCE) with intraocular lens implantation, were enrolled. All were given 3 ml of local anaesthetic (combination of equal amounts of lignocaine 2% and bupivacaine 0.5%) using retrobulbar technique. Intraocular pressure (IOP) was measured at different time intervals; before, immediately after...
متن کاملThe influence of retrobulbar adipose tissue volume upon intraocular pressure in obesity.
BACKGROUND/AIM It is known that glaucoma is associated with elevated intraocular pressure and obesity, yet the precise etiology remains unclear. The aim of this study was to determine whether there is a potential causality between the volume of retrobulbar adipose tissue and the level of intraocular pressure in obese subjects compared with non-obese. METHODS A total of 100 subjects were divid...
