[Trans-scleral diode laser cyclophotocoagulation for management of elevated intraocular pressure after pars-plana vitrectomy]

To evaluate the effect of trans-scleral cyclophotocoagulation [TSCPC] in reducing intraocular pressure in eyes with history of pars plana vitrectomy with or without intraocular silicone oil and refractory to medical treatment. Medical records of 35 eyes of 35 patients who underwent TSCPC for medically uncontrolled glaucoma after pars plana vitrectomy for retinal pathology were reviewed retrospectively. Diode laser contact TSCPC was performed at a power of 1-3 watt, for a duration of 2 seconds and with 15-30 applications. Intraocular pressure, visual acuity, number of previous operations, number of medications, number of treatment sessions per eye. Laser parameters and complications were evaluated. After a mean follow-up period of 13.31 +/- 4 [range 6-60] months, mean IOP was decreased from 33.46 +/- 9.80 [12-38] mmHg before surgery to 16.57 +/- 8.21 [2-46] mmHg after TSCPC [P<0.001]. The number of anti-glaucoma medications was reduced from 2.60 +/- 1.09 preoperatively to 1.31 +/- 0.99 at final follow up [P<0.001]. Qualified success and complete success were achieved in 29 [83%] and 9 eyes [20%], respectively. Patients with medically uncontrolled intraocular pressure following to pars plana vitrectomy with or without intravitreal silicone oil can be treated successfully with TSCPC

[Carotid wall thickness in patients with acute unilateral nonarteritic anterior ischemic optic neuropathy]

To compare ipsilateral and contralateral carotid wall thickness in patients with acute unilateral non-arteritic anterior ischemic optic neuropathy [NAION]. This prospective case series included 17 [10 male and 7 female] patients with unilateral NAION of less than 8 weeks' duration who underwent B-mode ultrasonography to measure intima-media thickness [IMT] in the common carotid and internal carotid arteries. IMT values of the affected side were compared with those on the contralateral side. Mean patient age was 59.6 +/- 10.8 [range 45-74] years. Mean interval between onset of NAION and measurements was 27.6 +/- 13.2 [range 10-45] days. Mean IMT of both common and internal carotid arteries on the affected side [1.19 +/- 0.14 and 1.41 +/- 0.29 mm, respectively] was significantly [P<0.001] higher than the noninvolved side [0.92 +/- 0.11 and 0.83 +/- 0.2, respectively]. NAION may be accompanied by increased carotid wall thickness. Carotid wall thickness measurement using ultrasound in patients with NAION may be useful to identify concomitant carotid artery disease
