Development and Clinical Application of An Quantitative Head-Band Formed Ocular Compressor

摘要

In order to investigate the efficiency of a new quantitative head-band formed ocular compressor to reduce intraocular pressure (IOP), ocular compression by this new reducer with 40 mmHg for 10 mm was performed on 87 cataractous eyes of 78 cases. The changes of IOP (87 eyes) and anterior chamber depth (ACD) were observed. There was a significant decrease of IOP and increase of ACD within 30 min after decompression (P<0. 001). The mean decrease of IOP was 5. 62+-2. 41 mmHg and the mean increase of ACD was 0. 18+-0. 09 mm within 5 min after decompression. The IOP 5 min after decompression had no significant difference with that 10 min after decompression (P >0. 05). IOP below 10 mmHg could last for about 15 min. This apparatus had been successfully applied to 80 eyes for extracapsular cataract extraction. It was suggested that this device had the advantages of safety, accurate quantification, reliable effect, casually adjusting pressure according to various demands and time-saving.
