Bacterial endophthalmitis after anterior chamber paracentesis.

Anterior chamber paracentesis in patients with acute elevation of intraocular pressure

“…Since patients are referred in an emergency situation and operating rooms are not always immediately available, the theoretical risk of ocular infection counterbalances the severe ocular tissue damage that could occur while waiting for an operating room. Endophthalmitis is a serious, vision-threatening and theoretical complication after ACP that has been reported [17], as has corneal abscess [18]. However, in our series, although small, we observed no signs of ocular infection after ACP.…”

“…IOP at 10 min, 1 day, 7 days and 1 month postoperatively was 24.1±12.5 mmHg (10-54), 18.2±11.1 mmHg (8-55), 16.4±10.7 mmHg (2-42) and 20.9±12.2 mmHg (10-55), respectively. At 1 year, IOP was 14.5±3.5 mmHg (6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21). The difference was statistically significant at 10 min and 24 h (P=0.0001) and at each time point.…”

Effect of the Honan intraocular pressure reducer on intraocular pressure increase following intravitreal injection using the tunneled scleral technique

“…Knip and Valimaki [26] report that prophylactic anterior chamber paracentesis helps to prevent the high post-operative IOP spike. However, anterior chamber paracentesis has the risk of complications, including lens damage, hyphema, patient discomfort, and infection [27][28][29][30]; in addition, vision-threatening endophthalmitis and corneal abscesses in the paracentesis tract have also been reported [31,32].…”

Nitric oxide levels in the anterior chamber of vitrectomized eyes with silicon oil

“…It may lead to some complications as secondary open angle glaucoma, cataract and corneal decompensation. The silicon oil in the vitreous cavity acts as a barrier to the oxygen diffusion, increasing its concentration in the anterior chamber (10)(11)(12)(13)(14)(15)(16) . The presence of silicon oil in the eye could change the oxygen tension in the anterior chamber, leading to an increase of nitric oxide concentration and oxidative stress.…”

“…Experimental studies demonstrated that silicon oil acts as a barrier to the diffusion of oxygen, maintaining a high oxygen concentration in the anterior chamber (10)(11)(12)(13)(14)(15)(16) . The oxygen tension in the anterior chamber is higher in eyes treated with lensectomy/ vitrectomy using silicon oil than in eyes just treated with lensectomy/vitrectomy (10) .…”
