THE EFFECTIVENESS OF THE DACRYOCYSTORHINOSTOMY OPERATION WITH PHYSIODISPENSER IN NASOLACRIMAL DUCT OBSTRUCTION

Purpose: To evaluate the effectiveness of the dacryocystorhinostomy (DCR) operation with physiodispenser in nasolacrimal duct obstruction.

Methods: Two hundred and twelve eyes from 150 patients with chronic dacryocystitis who had undergone external DCR operation with Kerrison punch were included in Group 1. Two hundred and fourteen eyes from 150 patients with chronic dacryocystitis who had undergone external DCR operation with physiodispenser were included in Group 2.

Results: There were no significant differences between the two groups in terms of age and sex (p > .05). Excessive bleeding requiring cauterization was observed in 41 (19%) patients in Group 1 and 8 (3%) patients in Group 2 (p < .05) during surgery. The mean operation duration was 32.36 ± 5.46 (26-42) minutes in the first group and 20.41 ± 4.98 (15-28) minutes in the second group (p < .05). Functional success rate at the end of the second postoperative year was 90.2% in the first group and 92.4% in the second (p > .05). Anatomical success rate at the end of second postoperative year was 95.8% in the first group and 98.1% in the second (p > .05).

Conclusion: DCR operation with physiodispenser shortens the operation duration, reduces excessive bleeding, and has high functional and anatomical success rates.

Keywords: Bleeding; dacryocystorhinostomy; operation duration; physiodispenser.

Facilitated Tenon-Free Conjunctival Autograft Preparation and Limited Tenon Removal Technique in Pterygium Surgery (Klinische Monatsblätter für Augenheilkunde – 2021)

by bart in Bilimsel Yayınlar, Uluslararası Hakemli Dergiler

FACILITATED TENON-FREE CONJUNCTIVAL AUTOGRAFT PREPARATION AND LIMITED TENON REMOVAL TECHNIQUE IN PTERYGIUM SURGERY

Background: The main complication of primary pterygium surgery is the recurrence of the pterygium. In the present study, we aimed to compare a classical technique and facilitated tenon-free conjunctival autograft preparation and a limited tenon removal technique in pterygium surgery in terms of recurrence rate, complications, and operation duration.

Material and methods: This is a retrospective, comparative, observational study. Group 1 comprised 120 eyes of 115 patients who underwent pterygium excision with a new facilitated tenon-free conjunctival-limbal autograft preparation and limited tenon removal technique between May 2017 and October 2019. Group 2 comprised 117 eyes of 113 patients who underwent pterygium excision with a conventional conjunctival-limbal autograft technique between January 2016 and May 2017.

Results: The mean follow-up time after surgery was 18.2 ± 5.8 months in group 1 and 19.1 ± 6.3 months in group 2 (p = 0.25). The mean operation duration was 5.54 ± 1.22 (4 – 7) minutes in group 1 and 8.23 ± 1.26 (8 – 10) minutes in group 2 (p = 0.02). Flap edema was present in 33 eyes (28.2%) in group 2 and in 11 eyes (9.16%) in group 1. Flap edema was significantly higher in group 2 (p < 0.001). At the end of the 1-year follow-up of the patients, we observed recurrence in only one (0.83%) eye in group 1 and 14 (11.96%) eyes in group 2. The recurrence rate of group 1 was significantly less than that of group 2 (p < 0.001).

Conclusions: The simplified technique of tenon-free conjunctival autograft preparation and limited tenon removal yielded better clinical outcomes without serious complications. Additionally, this technique shortened the surgical time and reduced surgeon-dependent factors.

Glaucoma disease diagnosis with an artificial algae-based deep learning algorithm (Medical & Biological Engineering & Computing 2022)

by bart in Bilimsel Yayınlar, Uluslararası Hakemli Dergiler

GLAUCOMA DISEASE DIAGNOSIS WITH AN ARTIFICIAL ALGAE-BASED DEEP LEARNING ALGORITHM

Glaucoma disease is optic neuropathy; in glaucoma, the optic nerve is damaged because the long duration of intraocular pressure can be caused blindness. Nowadays, deep learning classification algorithms are widely used to diagnose various diseases. However, in general, the training of deep learning algorithms is carried out by traditional gradient-based learning techniques that converge slowly and are highly likely to fall to the local minimum. In this study, we proposed a novel decision support system based on deep learning to diagnose glaucoma. The proposed system has two stages. In the first stage, the preprocessing of glaucoma disease data is performed by normalization and mean absolute deviation method, and in the second stage, the training of the deep learning is made by the artificial algae optimization algorithm. The proposed system is compared to traditional gradient-based deep learning and deep learning trained with other optimization algorithms like genetic algorithm, particle swarm optimization, bat algorithm, salp swarm algorithm, and equilibrium optimizer. Furthermore, the proposed system is compared to the state-of-the-art algorithms proposed for the glaucoma detection. The proposed system has outperformed other algorithms in terms of classification accuracy, recall, precision, false positive rate, and F1-measure by 0.9815, 0.9795, 0.9835, 0.0165, and 0.9815, respectively.

Keywords: Classification; Decision support; Deep learning; Diagnosis; Glaucoma disease.

Fusiform Anastomosis Technique with a Single Longitudinal Incision in the Lacrimal Sac in External Dacryocystorhinostomy (Klinische Monatsblätter für Augenheilkunde – 2022)

by bart in Bilimsel Yayınlar, Uluslararası Hakemli Dergiler

FUSIFORM ANASTOMOSIS TECHNIQUE WITH A SINGLE LONGITUDINAL INCISION IN THE LACRIMAL SAC IN EXTERNAL DACRYOCYSTORHINOSTOMY

Background: In the present study, we aimed to evaluate the surgical outcomes of the fusiform anastomosis technique in external dacryocystorhinostomy (ex-DCR) that we designed in the form of a physiological tube, which sufficiently covered the bone ostium with the mucosa.

Material and methods: This was a retrospective observational study that included 145 eyes of 131 patients who underwent ex-DCR due to nasolacrimal duct obstruction. The patients were divided into two groups. Group 1 included 73 eyes of 65 patients who underwent fusiform anastomosis, and group 2 included 72 eyes of 66 patients who underwent conventional anterior and posterior flap anastomosis. The open nasolacrimal passage with lacrimal irrigation and the absence of reflux were accepted as anatomical success, and the absence of epiphora symptoms was accepted as functional success. The groups were compared in terms of anatomical success, functional success, and granulation tissue formation.

Results: Anatomical success was observed in 73 eyes (100%) in group 1 and 66 eyes (91.6%) in group 2 (p = 0.01). Functional success was observed in 72 of 73 eyes (98.6%) in group 1 and 65 of 72 eyes (90.2%) in group 2 (p = 0.02). Nasal endoscopic examination performed in 32 eyes in group 1 and 28 eyes in group 2 revealed that granulation tissue was observed in 7 of 28 eyes (25%) in group 2, while there were no eyes with granulation tissue in group 1 (p = 0.01).

Conclusion: The fusiform anastomosis technique in ex-DCR provided excellent anatomical success and extremely good functional success.

Central retinal artery occlusion in a patient who contracted COVID-19 and review of similar cases (BMJ Case Reports CP – 2021)

by bart in Bilimsel Yayınlar, Uluslararası Hakemli Dergiler

CENTRAL RETINAL ARTERY OCCLUSION IN A PATIENT WHO CONTRACTED COVID-19 AND REVIEW OF SIMILAR CASES

A 54-year-old male patient applied to our clinic with a sudden and painless loss of vision in his right eye. He was suffering from COVID-19. His best-corrected visual acuity of the right eye was finger counting from 30 cm. The fundus examination revealed the presence of a ‘cherry-red spot’ appearance in the right eye. In optical coherence tomography imaging, hyper-reflectivity was observed in the inner retinal layers as well as increased retinal thickness in the right eye. In fundus fluorescein angiography, delayed arterial filling and prolonged arteriovenous transit time were observed in the right eye. The patient was diagnosed with central retinal artery occlusion after the COVID-19 infection. In this study, we report this case and its management.

Keywords: macula; retina.

Changes in Visual Field Indices after Pterygium Surgery (Beyoglu Eye Journal – 2021)

by bart in Bilimsel Yayınlar, Uluslararası Hakemli Dergiler

CHANGES IN VISUAL FIELD INDICES AFTER PTERYGIUM SURGERY

Objectives: This study was a prospective evaluation of changes in the results of visual field tests taken before and after pterygium excision.

Methods: This was a prospective, single-center study. Seventy-five eyes of 75 patients who had undergone pterygium excision with autograft implantation were enrolled. All of the patients had stage III pterygium according to the Johnston classification. The mean deviation (MD), pattern standard deviation (PSD), and visual field index (VFI) global index changes after pterygium excision were compared to evaluate the effect of pterygium on visual field analysis.

Results: The mean preoperative MD value was -3.04±2.63 dB (range: -14.84-0.62 dB) and the mean postoperative MD value was -1.83±2.09 dB (range: -13.82-1.74 dB) (p<0.001). The mean preoperative PSD value was 2.59±1.92 dB (range: 1.16-12.76 dB) and the mean postoperative PSD value was 2.41±1.62 dB (1.15-13.29 dB) (p>0.05). The mean preoperative VFI value was 96.01±4.46% (range: 68-100%) and the mean postoperative VFI value was 96.28±4.18% (range: 70-100%) (p>0.05).

Conclusion: After pterygium excision, the MD improved significantly. However, the PSD and VFI did not change significantly. The significant change in MD value was related to the reduction in corneal light scattering, contrast sensitivity, aberrations, and blockage on the optic axis.

Keywords: Mean deviation; pattern standard deviation; pterygium surgery; visual field index; visual field tests.

Objective: To evaluate the outcomes of posterior-cham-ber phakic intraocular lens (pIOL) implantation in patients with high myopia. Material and Methods: Seventy-six eyes of 38 patients who had high myopia and undergone Eyecrylphakic IOL implantation were enrolled in the study. Eighteen of them (47%) were males and 20 (53%) were females. Their mean age was 28.97±4.10 (22-36) years. Uncor-rected visual acuity (UCVA), best corrected visual acuity (BCVA), au-torefractive and keratometric measurements were evaluated pre and postoperatively. Results: The mean 1st week, 1st month and 6th month postoperative spherical, astigmatic and spherical equivalent (SE) values were significantly lower than those of preoperative values, and the mean 1st week, 1st month and 6th month postoperative UCVA and BCVA values were significantly higher than preoperative values (p< 0.05). The mean 1st week, 1st month and 6th month postoperative an-terior chamber depth (ACD) values were significantly lower than pre-operative values (p< 0.05). There were no significant differences between preoperative and postoperative central corneal thickness (CCT), endothelial cell density (ECD) and intraocular pressure (IOP) measurements (p> 0.05). The postoperative first-week mean spherical value was 0.11±0.44 D, and it was stable until the 6th month. Postoper-ative 6th month mean endothelial cell loss was 3% in comparison with preoperative values. The difference was not significant (p> 0.05). Ad-ditionally, no abnormal morphologic changes in endothelial cell layer were observed in specular microscopy. Conclusion: Eyecrylphakic IOL implantation is …
