The aim of this study was to determine the effects of the pneumoperitoneum used in colorectal procedures on peripapillary retinal nerve fibre layer (RNFL) thickness. We also analysed the dynamics of ocular anterior segment structures. In this prospective clinical pilot study, 29 patients aged between 45 and 85 years old underwent laparoscopic surgery for selected colorectal diseases. The pneumoperitoneum induced a mean intraocular pressure (IOP) increase of 4 mmHg. Visual acuity, IOP, corneal thickness, angle opening distance (AOD) and the trabeculo-iris space area (TISA) at 500 microns and 750 microns anterior to the scleral spur, RNFL thickness and visual field were measured before and after surgery using Sloan charts, Visante™ optical coherence tomography (OCT) (Zeiss, Oberkochen, Germany), Spectralis® OCT (Heidelberg Engineering, Heidelberg, Germany) and Humphrey Visual Field System® (Zeiss, Oberkochen, Germany). Patients were categorised in two groups to understand the behaviour of IOP: in group one (n=17), patients were in Trendelenburg position; in group two (n=12), patients were in reverse Trendelenburg position. The IOP was measured during surgery by the Icare® Tonometer (Icare, Vantaa, Finland) according to a standardised protocol; the IOP was measured before and after surgery by Goldmann applanation tonometer (Haag-Streit, Koniz, Switzerland). Patients with previous diagnosis of both open or angle-closure glaucoma or anterior segment anomalies were excluded. No statistically significant differences in increase of IOP were found between the two groups (p>0.05); no statistically significant differences in RNFL thickness, visual field, AOD and TISA were found before and after surgery in all patients (p>0.05). In our study we have demonstrated that a mean IOP increase of 4 mmHg over a short period of time is safe for a healthy optic nerve.

Introduction. According to the level of intraocular pressure (IOP), open angle glaucoma is divided into high tension glaucoma (HTG) and normal tension glaucoma (NTG). Objective. To determine if there are differences in the distribution of patients by age and sex between NTG and HTG. Methods. Our prospective study included 30 patients with NTG and 30 with HTG. A complete eye examination was performed. The examination included measuring of intraocular pressure by Goldmann applanation tonometry, examination of optic disc head by indirect ophthalmoscopy with Volk 90 D lens and visual field examination using the Octopus program. Results. The average damage of visual field in the group of patients with NTG was 8.14?4.43 dB, while in the group with HTG it was 7.40?2.84 dB (p>0.05). The average age of the group of patients with NTG was 66?11.58 years, while among those with HTG the average age was 59.7?11.63 years (p<0.01). Among the patients with NTG there were three times more women than men (?2=9.124; p<0.01), while in the group of patients with HTG there were more men than women, but without statistically significant difference between the tested groups (?2=1.851; p>0.05). Conclusion. Open angle glaucoma is a disease of elderly population. According to our results, risk factors for this disease can be age and sex. NTG is more frequently present than HTG among elderly population and females.

Purpose: Study clinical feature of phacomorphic glaucoma. To evaluate the result of treatment phacomorphic glaucoma. Method: The retrospective, interventional study on 36 cases with phacomorphic glaucoma who underwent treated at Hue Central Hospital from 6/2010 to 6/2011. Standard of research: visual, IOP, before and after surgery, accompanying lesions and post-operative complications. The surgery is considered successful when postoperative IOP less than 21 mmHg. Results: Age 50-59 presented 30.5 percent, ≥ 60 presented 91.7 percent. There was a slight female preponderance (66.7%) compared to the male population (33.3%) which implies a statistically marginally significant difference. However there was no statistical significance difference when compared by the two subgroups. Patient in country presented 61,1% and city presented 38,9%. The duration between the onset of pain and surgery from 0 to < 5 days (77.8%), from 6 to 10 (16.7%) and >10 days presented 5.5%. The preoperative intraocular pressure 35 to 45mmHg (47.2%), 46-55 (30.6%), 56-65 (13.9%) and more than 65 presented 8.3%. The visual acuity preoperation less than 1metre count finger (94.5%), less than 3 metre count finger presented 5.5%. Close anterior chamber angle presented 80.6% and shallow was presented 19.4%. Corneal edema presented 100%, iritis presented 94.4%, dilated pupil larger 5mm presented 83.3%, Synchynea iris and cataract presented 72.2%. ECCE, implantation IOL combined trabeculectomy presented 11.1%, Phaco, implantation IOL combined trabeculectomy presented 69,5%, ECCE implantation IOL presented 5.6%, Phaco, implantation IOL presented 13.8%. Postoperative visual acuity from 1/10 to 5/10 presented 72.2%, no case have VA larger than 5/10. Postoperative 3 months VA 1/10 to 5/10 presented 72.2%, larger VA 5/10 presented 8.3%. Postoperative 3 months intraocular pressure ≤ 21mmHg presented 91.7%, 22 to 24mmHg presented 8.3%, no case have IOP ≥25mmHg. Postoperative edema presented 58.3%, iritis presented 58.3%.

Introduction and Objective: Glaucoma is the leading cause of global irreversible blindness, signed by glaucomatous optic neuropathy related to visual field defect. The purpose of the study is comparing visual field defect examination using HVFA to Amsler Grid in glaucoma patient at dr. Kariadi Hospital. Methods: This is a cross-sectional study. Amsler Grid were performed to the patients who have reliable HVFA at last 6 months and presented as descriptive analytic results. Result: There were 40 eyes involved in this study from 27 patients (15 men, 12 women), 26-68 years old and visual acuity 1/60-6/6. Seventeen eyes showed visual field defect in HVFA and Amsler Grid had average MD - 24.97 dB, CDR 0.89 and RNFL thickness 51.74. We found that 11 eyes didn’t showed in both of examination had average MD -8.06, CDR 0.63 and RNFL thickness 103.23 and those parameters are significantly different to the 17 eyes before (p<0.05). Data from 12 eyes that showed visual field defect only one of examination (9 only in HVFA and 3 in Amsler Grid) didn’t show difference statistically each other. Conclusion: HFVA and Amsler Grid seemed to be comparable in detecting visual field defect in advanced glaucoma.
