Purpose:To evaluate the outcome of the external dacryocystorhinostomy with and without suturing the posterior mucosal flaps.Methods:This study included 106 patients with lacrimal drainage system disorders who underwent the external dacryocystorhinostomy. Fifty four patients (Group A) underwent external dacryocystorhinostomy with suturing anterior and posterior flaps of the lacrimal sac and nasal mucosa, and the results obtained were compared with those of another series of 52 patients (Group B) where dacryocystorhinostomy was performed with suturing only the anterior flaps, whereas posterior mucosal flaps were excised.Results:The success rate was evaluated by lacrimal patency to irrigation and relief of epiphora. Patency achieved in groups A and B was 94.4% and 96.2%, respectively. There was no statistically significant difference in success rate between the groups.Conclusion:Our study suggests that external dacryocystorhinostomy with suturing anterior and posterior flaps have no advantage over dacryocystorhinostomy with suturing only anterior flaps. Anastomosis by suturing only anterior flaps and excision of the posterior flaps is easier to perform and may improve the success rate of external dacryocystorhinostomy.

The aim of this study was to examine the relationship between psychosocial stress and intraocular pressure among apparently healthy subjects. Psychosocial stress among 1,461 public school workers (883 men and 578 women) was measured using the inventory to measure psychosocial stress (IMPS) and intraocular pressure was measured using a non-contact tonometer (Topcon CT-90). After controlling for the effects of likely confounding variables such as age, body mass index (BMI), glycosylated hemoglobin, systolic blood pressure, alcohol consumption, smoking status, and exercise, partial correlations and hierarchical multiple regression analysis were performed in order to test the hypothesis that IMPS-measured stress score was associated with intraocular pressure. IMPS-measured stress score was found to correlate positively with intraocular pressure in women after controlling for the effects of confounding variables, whereas this relationship was not found in men. Hierarchical multiple regression analysis indicated that IMPS-measured stress score was positively associated with intraocular pressure in women independent of confounding variables, but not in men. Perturbations of the hypothalamicpituitary-adrenal (HPA) axis associated with stress are considered to be partly responsible for an increase in intraocular pressure among people suffering from psychosocial stress. Further research is needed to elucidate the relationship between this stress-associated increase in intraocular pressure and open-angle glaucoma.

Introduction: External dacryocystorhinostomy is a surgical procedure for the treatment of lacrimal drainage system disorders. Aim: To assess the usefulness of different silicone tubes in external dacryocystorhinostomy. Material and Methods: This study sampled 97 patients with lacrimal drainage system disorders who underwent the external dacryocystorhinostomy using two different silicone tubes. Forty one patients (Group A) underwent external dacryocystorhinostomy with silicone intubation using Nunchaku-style tubes, while in 56 patients (Group B) dacryocystorhinostomy was performed with O‘Donoghue silicone tubes. The data was analyzed using T-test, Chi-squared test and Fisher’s test. Results: The success rate was evaluated by achieved patency to irrigation and relief of epiphora. Patency in the group with Nunchaku-style tubes was 95.1% compared to 94.6% in the group with O‘Donoghue silicone tubes (p>0.05). Conclusion: Both tubes in external dacryocystorhinostomy were useful in the management of lacrimal drainage system disorders. Although it is easier and quicker to intubate and extubate Nunchaku-style tubes compared to O‘Donoghue silicone tubes, there was no statistically significant difference in success rate between the compared groups.

Purpose:In this study, we have researched the possible parametrically changes before and after LASIK (laser-assisted in situ keratomileusis) and the influence of these changes in the cause of post LASIK ectasia.Materials and methods:In this study 204 eyes with different refractive anomalies were included. Candidates that underwent refractive surgery first have to undergo many ophthalmological examinations, firstly by evaluating their visual acuity, subjective and objective refraction with and without cycloplegia, slight lamp evaluation, computerized topography, pupillometry, retina examination and measurement of intraocular pressure. Pachymetric values were measured with Orbscan IIz (Bausch – Lomb). Refractive surgery was done with LASIK under local anesthesia.Results:In this study 102 patients were treated with LASIK who were with different refractive anomalies. According to the group age 44 or 43.1% were of the age 20 – 29, 46 or 45.1% were of the age 30 – 39, 11 or 10.8% were 40 – 49 years of age and 1 or 1% were above the age of 50 +. Pachymetric before surgery in right eye was approximately 565.4 µm (DS+- 39.4), from 507 µm up to 678 µm, but after surgery it was approximately 497.5 µm (DS+-61.7) from 346 µm up to 644 µm. Pachymetric on the left eye before surgery was approximately 564.8 µm (DS+-41.5) from 504 µm up to 696 µm but after surgery it was approximately 498.3 µm (DS+-62.2), from 329 µm up to 646 µm. Pachymetric in both eyes before surgery was approximately 549.1 µm (DS+=73.9), from 263 µm up to 687 µm. Pachymetric on both eyes after surgery was approximately 496.9 µm (DS+-60.1), from 337.5 µm up to 645 µm. With the “ Paired T – test “ we have reached a significant statistical change between the pachymetric values in both eyes before and after the surgery (P<0.0001).Conclusion:Corneal thickness is one of the main criteria in order to allow refractive surgeries, and as the main criteria it was evaluated at our patients treated with LASIK.

Introduction:Laser in situ keratomileusis (LASIK), a refractive surgery procedure is being performed in a large number among people with refractive errors. In all the people undergoing the procedure, there is a potential risk to misdiagnose the glaucoma disease due to changes in central corneal thickness (CCT). In subjects who have undergone laser refractive interventions, intraocular tension may be lower and underestimated, and this can lead to later detection of glaucoma.Aim:The objective of this study was to analyze the intraocular pressure (IOP) after LASIK in patients with myopia.Methods:Thirty-seven patients underwent LASIK intervention to treat myopia. In total, 74 eyes were treated. Before the intervention, all patients underwent complete ophthalmologic examination, including the measurement of central corneal thickness (CCT) and measurement of IOP with non-contact tonometer. The IOP was also measured on days 1, 3 and 30 after the surgery. The mean IOP was taken for statistical analysis.Results:Seventy-four eyes of 37 patients (mean age 31.6) underwent LASIK intervention to treat myopia. Mean CCT before the intervention was 551.9 ±31.9µm, while mean postoperative CCT was 469.8 ±45.3µm (p<0.0001). Mean preoperative IOP was 16.4mmHg while mean postoperative IOP was 11.0mmHg (p<0.0001). The average spherical equivalent was -5.9 diopters.Conclusions:The reduction of IOP after LASIK refractive surgery is significant. This reduction is about 1mmHg per 1 diopter. This should be taken into account in the future in these patients because, due to the underestimation of the IOP, the glaucoma disease may be overlooked.
