Effects of body mass index on intraocular pressure and ocular pulse amplitude

AIM: To investigate the effects of body mass index (BMI) on intraocular pressure (IOP) and ocular pulse amplitude(OPA). METHODS: Totally 140 healthy individuals without any systemic diseases were included in the study. BMI (kg/m2) was calculated for every individual. IOP and OPA were measured with Pascal Dynamic contour tonometer (DCT). Blood pressure was also measured along with the DCT. The patients were divided into three groups according to BMI as: Group1, BMI<25; Group2, 25≤BMI<30; Group3, BMI≥30. Mean values of IOP, OPA, systolic blood pressure (SBP) and diastolic blood pressure (DBP) were used in statistical analysis.RESULTS: In Group1, the means of IOP, OPA, were 16.8±2.3mmHg, 2.7±0.7mmHg respectively; and SBP, DBP were 120.0±6.1mmHg, and 77.4±5.6mmHg respectively. In group2, the mean IOP, OPA, SBP, and DBP were found to be 16.6±2.1mmHg, 2.4±0.7mmHg, 121.7±5.3mmHg, and 79.5±4.9mmHg respectively. In group3, the mean IOP, OPA, SBP, and DBP were found to be 17.3±1.7mmHg, 2.1±0.7mmHg, 122.4±5.7mmHg, and 79.7±5.2mmHg respectively. There were no statistically significant difference between groups in terms of IOP, SBP and DBP, while OPA values were significantly lower in group3 (P=0.001). CONCLUSION: Decreased OPA values in individuals with higher BMI may indicate that subjects with higher BMI have lower choroidal perfusion and lower ocular blood flow.

Ex-PRESS implantation for different types of glaucoma

AIM: To evaluate the clinical results, efficacy and safety of Ex-PRESS P200 glaucoma shunt implant in different types of medically uncontrolled glaucoma. METHODS: The study included 31 eyes of 31 patients that were unresponsive to medical antiglaucomatous therapy in whom Ex-PRESS P200 glaucoma shunt implantation was performed. The demographic characteristics of the patients, type of glaucoma, complete ocular examination results, number of antiglaucomatous drugs before and after surgery, early and late complications of surgery, additional surgical and nonsurgical medical interventions, and success rates were investigated from the patients’ files, retrospectively. RESULTS: The mean postoperative follow-up time was 16.4±7.5 mo. The preoperative mean corrected intraocular pressure(IOP) was 28.7±10.3 mm Hg and postoperative mean corrected IOP was 15.3±5.2 mm Hg(P<0.05) at the last visit. The mean IOP reduction was 39.9% when the preoperative and postoperative values of the last visits were compared. The average number of antiglaucomatous drug use decreased from 3.9±0.3 to 1.7±1.7 postoperatively(P<0.05). The use of antiglaucomatous medications at the last visit was more than in other studies in the literature. The most common complication was conjunctival leakage, which was seen in 7 patients. Other early complications were iris touch, intravitreal hemorrhage, hyphema, choroidal effusion, early transient hypotonia and corneal edema. One of the late complications was endophthalmitiswhich was seen in one case 6 mo after the operation, and the other late complication was opacification of the cornea in one patient. Twelve additional surgical operations associated to Ex-PRESS surgery and 3 bleb needling have done. At the last visit, the complete success rate was 32.3% and the qualified success rate was 77.5% in all patients. CONCLUSION: Ex-PRESS P200 glaucoma shunt implantation may be an effective procedure for medically uncontrolled glaucoma with significantly lower use of antiglaucomatous medications.

在 vitrectomized 眼睛的一种合理选择: 用手的小切口奔流外科

Dear Sir,It is known that cataract surgery is challenging in vitrectomized eyes.Cataract surgeons may have encountered with posterior capsular complications and nucleus drop events even with minimal ocular manipulations and low irrigation bottle height.Inadvertent damage to the zonular fibers,posterior or peripheral lens capsule with ocutome or microvitreoretinal(MVR)blade in
