Purpose: To compare the efficacy and safety of cold saline solution (0.9% NaCl) with topical ophthalmic proparacaine for maintaining topical anesthesia of patients undergoing phacoemulsification surgery., Methods: The prospective, double-blinded, and randomized clinical study was randomly assigned to two groups that underwent phacoemulsification surgery due to cataracts. The cold saline group included 86 eyes of 86 patients with topical anesthesia of cold saline solution alone. The proparacaine group included 84 eyes of 84 patients with topical ophthalmic proparacaine (room temperature) anesthesia alone. The patients were scored according to a pain survey questionnaire of Visual Analog Scale (VAS) ranked between 0 and 10. The surgeon scored surgical experience by a Surgeon Questionnaire Scale (SQS) in three parameters, each of which was ranked from 1 to 3 based on questions regarding ease and comfort during the surgery., Results: The mean VAS scores were 1.29 ± 0.65 and 1.22 ± 0.66 for the cold saline and proparacaine groups, respectively (P = 0.182). The mean scores of SQS (lower values represented favorable results) were 4.11 ± 0.76 and 3.97 ± 0.74 in the cold saline and proparacaine groups, respectively (P = 0.163). Ten patients in the proparacaine group experienced corneal epitheliopathy in the postoperative period., Conclusion: As an easily accessible and cost-effective method, cold saline solution alone might be an alternative to topical ophthalmic proparacaine alone with comparable safe and effective results. The absence of allergic or toxic effects also provided a significant advantage in the cold saline application., Competing Interests: None

Purpose: To determine the demographic and clinical characteristics of newborn patients who underwent lacrimal probing surgical intervention with or without the marsupialization of intranasal cysts as the primary management for dacryocystocele treatment., Methods: Data from the medical charts of 350 infants who underwent lacrimal probing surgery due to nasolacrimal duct obstruction were reviewed retrospectively. Ten newborn patients with a naive diagnosis of congenital dacryocystocele were included in the study. Congenital dacryocystocele diagnosis was based on a triad of swelling in the inner canthal region, a bluish appearance, and epiphora. Lacrimal probing surgery accompanied by nasal endoscopy was planned for all patients as the first treatment option., Results: The mean age of the patients was 24.90 ± 7.15 days, with a range of 6-85 days. A total of 10 patients were included, comprising seven females and three males. The mean postoperative follow-up period was 38.7 ± 24.41 months. Five patients had left, four patients had right, and one patient had bilateral dacryocystocele. Seven eyes of the six patients had uncomplicated dacryocystocele, while the remaining patients had dacryocystocele with complications of dacryocystitis and/or preseptal cellulitis. All patients had intranasal cysts. All patients underwent one session of lacrimal probing surgery under general anesthesia; all with successful outcomes. Four patients with additional dacryocystocele-associated complications underwent combined intranasal marsupialization of the cyst wall., Discussion: Lacrimal probing surgery ± intranasal marsupialization of the cyst wall as a first treatment option can be effective for both congenital dacryocystocele and/or congenital dacryocystocele plus associated complications and provide complete resolution of dacryocystocele-related symptoms., Competing Interests: Conflict of interest statement: The authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s), 2021.)

Purpose: To evaluate anatomical and functional results of osseointegration with magnetic coupling for oculofacial prosthetic rehabilitation after exenteration., Methods: This retrospective study included 11 consecutive patients who received orbital reconstruction and oculofacial prosthetic rehabilitation between September 2015 and October 2019. Patient demographics, surgical indications, previous treatment procedures, histopathologic features, and reconstructive procedures were recorded., Results: The mean age was 37.81 ± 23 years (range 5-78 years). The mean follow-up was 23.81 ± 12 months (range 10-48 months). The principal diagnoses were squamous cell carcinoma of the eyelids (n = 2/11), mucoepidermoid carcinoma of the maxillary sinus (n = 2/11), rhabdomyosarcoma (n = 1/11), mucormycosis (n = 1/11), neurofibromatosis (n = 1/11), basosquamous carcinoma (n = 1/11), malign melanoma (n = 1/11), primitive neuroectodermal tumor (n = 1/11), and retinoblastoma (n = 1/11). Six of the patients were repaired by primary closure. Procedures performed to reconstruct the orbital cavity included split-thickness skin graft (n = 2/11), temporalis muscle flap (n = 2/11), and frontalis muscle flap (n = 1/11). Nine of the 11 patients who received orbital implants were successfully rehabilitated by epithesis. Postoperative complications included implant loss (n = 4/11), periprosthetic local infection (n = 3/11), and soft tissue overgrowth around the orbital prosthesis (n = 2/11). All patients had Straumann bone level implant (Basel, Switzerland) osseointegrated titanium implants (3.5 mm) placed in a 2-stage procedure over a span of 3 to 4 months with subsequent successful prosthesis fitting., Conclusion: The reconstructive methods following orbital exenteration, should be customized according to the patients' characteristics such as extension of the orbital defect, bone quality, and expectations to achieve satisfactory results., Competing Interests: The authors report no conflicts of interest., (Copyright © 2021 by Mutaz B.

Purpose: To assess and compare demographic and clinical features of benign and malignant eyelid tumors from 2011 to 2018 in a tertiary medical center., Materials and Methods: The study was conducted retrospectively from medical records to compare demographic and clinical characteristics and recurrence of benign and malignant eyelid tumors after obtaining institutional review board approval. A total of 428 eyelid tumors with histopathologic diagnoses were studied. Premalignant lesions were not included. The lesions were classified into two groups according to malignancy: benign and malignant eyelid lesions., Results: Among the 428 histopathologically confirmed eyelid lesions, 373 (87.1%) were benign and 55 (12.9%) were malignant. The patients with malignant eyelid tumors had a higher mean age at diagnosis than patients with benign eyelid tumors (P=0.012). The most common benign eyelid tumors were squamous papilloma (17.7%), xanthelasma (11.5%), and epidermal cysts (11.3%). The most common malignant eyelid tumors were basal cell carcinomas (65.5%), squamous cell carcinomas (14.5%), and sebaceous gland carcinomas (7.3%). There was no relative gender predominance between patients with benign and malignant eyelid tumors (P=0.287). Benign eyelid tumors were most commonly located on the right side and upper eyelid (P=0.027 and 0.036, respectively). Malignant tumors had a higher rate of recurrence (P=0.002)., Conclusion: Differentiation between benign and malignant eyelid lesions is important, since it may lead to cosmetic complications and serious morbidity, particularly in patients with malignant eyelid tumors., (Copyright © 2021 Elsevier Masson SAS.

Purpose: To compare the short-term changes in corneal endothelial cells after trabeculectomy or XEN Gel Stent implantation., Design: Prospective, interventional, comparative study., Methods: Changes in corneal endothelium in patients that underwent XEN Gel Stent implantation or trabeculectomy were prospectively evaluated. Eighty eyes of 62 diagnosed with open-angle glaucoma were divided into two the trabeculectomy and XEN Gel Stent groups. Corneal specular microscopy was performed at the central cornea using a noncontact specular microscope preoperatively and 3 months after surgery., Results: The baseline mean corneal endothelial cell density in the trabeculectomy group was 2390.3 ± 324.8 cells/mm 2 , and this was significantly reduced to 2148 ± 352.5 cells/mm 2 3 months after surgery, representing a cell loss of 10.0% (p < 0.001). The baseline mean corneal endothelial cell density in the XEN Gel Stent group was 2156.2 ±559.7 cells/mm 2 , and this was significantly reduced to 2098.4 ± 556.2 cells/mm 2 3 months after surgery, representing a cell loss of 2.1% (p = 0.002). The corneal endothelial cell density change rate of the trabeculectomy group (-10.0% ± 9.7%) was statistically higher than the XEN Gel Stent group (-2.1% ± 13.8%) (p = 0.002). A statistically significant difference was observed in the trabeculectomy group between the baseline and postoperative values in the coefficient of variation (p = 0.029)., Conclusion: Trabeculectomy caused more endothelial cell damage than XEN Gel Stent implantation in the short-term follow-up period. The XEN Gel Stent may be the treatment of choice in patients with a significantly low preoperative corneal endothelial cell density.

Purpose: To present clinical ocular manifestations, radiological features and surgical results of giant paranasal osteomas involving the orbit., Design: Retrospective, interventional, case series., Methods: The study included patients treated for giant paranasal osteoma involving the orbit. Total or subtotal excision of the tumor was performed via external approach. Clinical characteristics including presenting symptoms, radiologic investigation, histopathology and details of the surgery were recorded., Results: Of the six patients included; four were male and two were female. Mean age was 46.8 years (range 12-70 years). Five patients had unilateral, one patient had bileteral disease. The presenting complaints included complete ( n  = 2/6) or partial ( n  = 4/6) limitation of eye movements depending on the location and size of the tumor, diplopia ( n  = 5/6), vision loss ( n  = 2/6) exophthalmos ( n  = 6/6) and reduced pupillary light reflex ( n  = 2/6). The presumed origin of the tumor was frontoethmoidal region ( n  = 2/6), frontal sinus ( n  = 3/6) and ethmoid sinus ( n  = 1/6). Total resection was achieved in three of the patients whereas partial resection was achieved in remaining three patients due to risk of incremental neurological damage. Mild ptosis was observed in all patients during the postoperative period (temporary, n  = 4; permanent, n  = 2)., Conclusion: Despite the benign nature of osteomas, severe functional impairment including vision loss due to compression of the optic nerve and diplopia might occur in case of orbital involvement. Osteomas with an orbital extension > %50 of the bony orbit volume are more prone to cause irreversible visual loss. Surgical resection is still the mainstay of therapy.

Purpose: To investigate whether impaired lacrimal pump function is a possible cause of discharge in patients wearing an artificial eye compared with the remaining healthy eye., Methods: Consecutive patients wearing unilateral ocular prosthesis for ≥6 months were included in this retrospective study. Excluded were any deformities of eyelids or nasal passage, socket complications such as entropion, ectropion, ptosis, infection, pyogenic granuloma, contracted socket, obstruction of nasolacrimal duct diagnosed with lacrimal irrigation and a difference greater than 2 mm in terms of protrusion between two eyes detected by Hertel exophthalmometry. Patients were asked to score the levels of tearing and mucopurulent discharge between 0 and 5 to assess lacrimal drainage function subjectively. Furthermore, dacryoscintigraphy was performed to assess the functional status of the lacrimal system objectively., Results: Included were 32 subjects (12 females, 20 males; aged 32.94 ± 17.62, range 13-78). Mean duration of prosthetic wearing 26.41 ± 21.30 (6-72) months. The mean subjective scores of tearing and mucopurulent discharge were 1.56 ± 1.67 and 1.94 ± 1.63, respectively. The rate of functional stenosis was significantly higher in the anophthalmic socket side as compared to the healthy side (P = 0.002). The rates of a presac, preduct, and intraduct obstruction was notes as n = 9, n = 10, n = 1 and n = 0, n = 6, n = 2 in the anophthalmic side and the companion eye, respectively (P = 0.021)., Conclusion: Compared to paired healthy eyes, the ocular prosthesis exhibited significantly higher rates of functional lacrimal duct obstruction, especially at the presac level. The alterations in orbital volume and tear film composition in addition to reduced corneal reflex blinking may lead to the failure of lacrimal pump function in artificial eyes.

Objectives: The aim of this study was to assess the effects of topical 0.1% nepafenac and 0.1% fluorometholone on macular thickness (MT) after a neodymium: yttrium-aluminum-garnet (Nd: YAG) laser posterior capsulotomy and to compare the findings with those of untreated patients., Methods: This prospective study included 75 eyes of 75 patients with posterior capsule opacification. The patients were divided into 3 groups according to the medications administered after a capsulotomy procedure. Group 1 comprised 25 patients who were prescribed 0.1% nepafenac for a week, Group 2 consisted of 25 patients who were prescribed 0.1% fluorometholone for a week, and Group 3 consisted of 25 patients who were not prescribed any medication. A circular-shaped capsulotomy was performed in all cases. MT was measured before the capsulotomy and at the first day, first week, and first month after the procedure using spectral domain-optical coherence tomography and the change values were compared within and between groups., Results: In Group 1, the superior and nasal parafoveal MT, temporal, and nasal perifoveal MT values at the first month were statistically significantly greater than those observed in the first week (p<0.05 for all values). In Group 2, the superior and nasal parafoveal MT and inferior perifoveal MT measurements in the first month were greater than those recorded the first week (p<0.05 for all values). In Group 3, there was a gradual increase seen in the first day, first week, and first month in the superior and temporal parafoveal MT value (p<0.05 for all). The change value in the parafoveal temporal quadrant was significant between groups, indicating a greater increase in the untreated group compared with the nepafenac and fluorometholone groups (p=0.04)., Conclusion: An increase in MT can occur after an Nd: YAG laser posterior capsulotomy. Both topical 0.1% nepafenac and 0.1% fluorometholone can prevent this increase. The 2 drugs were comparable; neither demonstrated apparent superiority to the other., Competing Interests: Conflict of Interest: None declared., (Copyright: © 2020 by Beyoglu Eye Training and Research Hospital.)

Purpose: To evaluate the demographic characteristics and visual outcomes of patients with open globe injury (OGI) in a tertiary hospital in Istanbul, Turkey., Methods: The data of patients admitted with OGI to Sisli Hamidiye Etfal Training and Research Hospital, Istanbul, Turkey from January 2012 to December 2017 were reviewed retrospectively, and 100 of the 154 patients were included in the study., Results: There were 79 (79%) male and 21 (21%) female patients with the average age of 33.7 ± 20.7 (1-83). Presentation of the patients was more frequent in the first 3 days of the week (Monday 20%; Tuesday 17%; and Wednesday 20%) and within working hours (8 a.m.-5 p.m., 71%). The most common injury type was penetrating injury (75%), which was mostly caused by sharp objects (metal objects 32% and broken glass 22.7%). The ocular trauma score (OTS) was significantly higher in patients with penetrating injury and intraocular foreign body injury (p < 0.001), and those results were correlated with better visual prognosis. The patients with penetrating injury among the injury types and zone I injury among the injury zones had the highest final visual acuity. Patients in the age group of 0-14 years had statistically better visual outcome when compared to those in the other age groups (p = 0.003)., Conclusions: The higher initial visual acuity and OTS, penetrating injury, zone I injury and pediatric age are good prognostic factors for OGI. Additionally, scheduling a prepared surgical team and tools in working hours will be beneficial according to the frequency of admissions.

Purpose: To compare two different frontalis sling approaches, tarsal fixation and orbicular muscle fixation, using silicone rod (FCI Ophthalmics, Marshfield Hills, MA, USA) in terms of postoperative upper eyelid contour in patients with poor levator muscle function., Design: Retrospective, comparative, case series., Methods: Ten eyes of seven patients who received frontalis sling surgery with orbicularis muscle fixation (group 1), eight eyes of seven patients who received frontalis sling surgery with tarsal fixation (group 2) and 30 eyes of 15 age and sex-matched healthy controls (control group) were included. Postoperative photographs of all the participants were taken in the primary gaze, and each photograph was viewed on a computer. The distance between the upper lid margin and pupillary center (MCD), nasal limbus (MND), and temporal limbus (MTD) was measured, respectively, using the ruler in Microsoft Paint Software and compared with each other for each participant., Results: Both nasal, central and temporal margin distance values in group 1 and group 2 were significantly lower than those of the control group (p < 0.05 for all values). The ratio of MTD/MCD in the control group was significantly higher than group 1 (p = 0.04) besides the ratio of MND/MTD in the control group was significantly lower than group 1 (p = 0.01)., Discussion: Frontalis sling approach with tarsal fixation using silicone rod might provide improved cosmetic results including more symmetrical upper eyelid contour compared with orbicularis muscle fixation approach. Moreover, the novel measuring technique presented in the current study provides a simple and effective assessment of the upper lid contour in daily practice setting., Level of Evidence Iii: This journal requires that authors assign a level of evidence to each article.

Purpose: To investigate the effect of microalbuminuria on macular thickness in patients with type-2 diabetes mellitus with no or mild diabetic retinopathy and to investigate the relationship between macular thickness and metabolic parameters., Materials and Methods: Fifty eight eyes of 58 patients without diabetic retinopathy (group 1) in microalbuminuria stage, 42 eyes of 42 patients with mild diabetic retinopathy (group 2) in microalbuminuria stage, and 50 eyes of 50 patients without diabetic retinopathy and microalbuminuria (group 3) were included in this study. After detailed ophthalmologic examination, all patients underwent spectral domain-optical coherence tomography measurements. Macular thickness was noted from nine different areas (fovea, four parafoveal, and four perifoveal areas) and compared between groups. The correlations between macular thickness and age, duration of diabetes mellitus, microalbuminuria, serum urea, creatinine, glycosylated hemoglobin (HbAIc), albumin, sodium (Na), and urinary Na were evaluated., Results: The mean age was 53.29 ± 6.49 in group 1, 55.86 ± 6.97 in group 2, and 52.98 ± 5.66 years in group 3 (p = 0.06). The macular thickness values of superior, inferior, and nasal parafoveal areas were significantly different between groups (p = 0.001, p = 0.006, and p = 0.03, respectively). Bonferroni post test revealed that this difference originated from the difference between group 2 and 3 (p < 0.05 for all values). There were significant negative correlations between the macular thickness values of parafoveal areas and serum urea, HbA1c, albumin, microalbuminuria levels (p < 0.05 for all values)., Conclusion: In this study, a significantly decreased parafoveal macular thickness was measured in patients with mild diabetic retinopathy and microalbuminuria compared to patients without diabetic retinopathy and microalbuminuria.

Purposes: To identify problems caused by prosthesis-socket volume imbalances in anophthalmic sockets; and to evaluate rehabilitation with dermofat graft as a solution., Methods: We retrospectively reviewed medical records of patients operated in our clinic (between May 2011 and June 2016) with dermofat grafts to treat anophthalmic socket-related problems. During the preoperative examinations, ophthalmologists recorded the presence of eyelid problems due to the socket volume deficit, upper and lower fornix deficiency, deepening in the upper eyelid sulcus, epiphora and secretion, lower eyelid laxity, ptosis, entropion, and ectropion. Following the surgical repair, new prosthesis suitable for the resulting socket area were implemented for all the patients. The mean follow-up period was 27.42±16 months (ranging from 10-62 months). On the last control examinations, ophthalmologists recorded solved and unsolved socket problems that were present preoperatively., Results: We included 16 men and 5 women in this study. The mean age was 38.3 ± 18.4 years (range, 5-75 years). The mean duration of preoperative prosthesis use was 9.4 ± 6.8 years (range, 1-30 years). Preoperatively, 7 patients had only orbital volume deficits, and 14 had socket volume displacements in addition to the volume deficits. After the dermofat graft implantations, the remaining deficits were corrected during another surgical session: 6 patients underwent ptosis corrections, 5 lateral canthal suspensions, 5 lower fornix with mucosal graft formations, and 2 upper fornix formations with mucosal grafts. All patients were able to use prosthesis postoperatively., Conclusion: The use of dermofat grafts to correct anophthalmic socket problems caused by orbital volume deficits or volume displacements is an effective, reliable, and reproducible surgical method.

Purpose: To compare the results of 3 evisceration techniques involving placement of an acrylic implant within the scleral shell without posterior sclerotomy (Group 1), posterior sclerotomy with placement of a porous implant within the intraconal space (Group 2) and posterior sclerotomy with placement of a acrylic implant within the intraconal space (Group 3) with respect to ocular mobility, implant complications and patient satisfaction., Methods: Single-center, retrospective, interventional case series. A chart review of 72 patients undergoing evisceration between February 2013 and January 2018 was carried out. Thirty-five patients met the inclusion criteria having a normal or near normal size eye and at least 6 months follow-up. The horizontal movements of the implant and the artificial eye was measured by using a ruler. Data analyses were conducted using the Mann-Whitney U test for 2 independent samples., Results: Neither infection nor prolapse of the implant had occurred in any of the patients. The mean implant sizes were 18 mm in Group 1, 20 mm in Group 2 and 20 mm in Group 3. Statistically, a significant difference was assessed between Group 1 and Group 2 in both nasal and temporal movement of the socket; nasal and temporal movement of the prosthesis. Statistically, a significant difference was assessed between Group 1 and Group 3 in both nasal and temporal movement of the socket; nasal and temporal movement of the prosthesis. However, there was no statistically significant difference between Group 2 and Group 3 in neither nasal and temporal movement of the socket nor nasal and temporal movement of the artificial eye., Conclusion: Group 1 showed the significantly better movement of both prosthesis and socket in adduction and abduction than Group 2 and 3. The likely explanation for this may be that preserving the scleral shell integrity allows more efficient transmission of muscle contraction to the socket and prosthesis.

Purpose: We aimed to investigate the effect of combined phacotrabeculectomy, trabeculectomy and phacoemulsification on the corneal endothelium in the early stage., Materials and Methods: In this prospective and non-randomized study, three groups were identified each consisting of 20 eyes (Group I phacotrabeculectomy, group II trabeculectomy, group III phacoemulsification). In the pre- and postop month 1, corneal endothelial cell density (CECD), coefficient of variation (CV) (polymegathism) and hexagonality (Hex) (pleomorphism) were measured by means of a non-contact specular microscope (Nidek CEM-530, NIDEK Co., Ltd. Japan)., Results: The postop CECD in each of the three groups showed a significant decrease when compared with the preop period (6.1% in the phacotrabeculectomy group, 4.9% in the trabeculectomy group and 7.4% in the phacoemulsification group). The amount of decrease in the preop and postop CECD values showed no significant difference among these three groups. The postop CV value in each of the three groups showed a significant increase when compared with the preop period. The postop Hex value in each of the three groups showed no significant change when compared with the preop period., Conclusion: In our study, we observed that performing a combined phacotrabeculectomy on patients with glaucoma and cataract association in the same session did not do more harm to the corneal endothelium than other surgical methods. For this reason, this method can be applied safely to a patient population that is likely to develop corneal decompensation.

Purpose: The aim of this retrospective, nonrandomized, observational clinical study was to evaluate the screening results for retinopathy of prematurity (ROP) of late-preterm infants born at 32-35 weeks gestational age (GA)., Methods: Retinopathy screening data of late-preterm infants were evaluated between January 2015 and September 2018. The zones and stages of ROP development were classified according to the International ROP Committee criteria. Patients were categorized into four groups according to GA: 32 < 33 weeks GA, 33 < 34 weeks GA, 34 < 35 weeks GA, and 35 < 36 weeks GA. The rates of development of any stage of ROP or severe ROP (requiring treatment) were recorded., Results: The study included 543 infants: 139 (25.4%) in 32 < 33 weeks GA, 127 (23.6%) in 33 < 34 weeks GA, 162 (30.2%) in 34 < 35 weeks GA, and 115 (20.8%) in 35 < 36 weeks GA. Different stages of ROP developed in 29 infants (20.9%) in 32 < 33 weeks GA, 19 infants (15%) in 33 < 34 weeks GA, 17 infants (10.5%) in 34 < 35 weeks GA, and 6 infants (5.2%) in 35 < 36 weeks GA. Treatment was required for 14 infants (2.6%) due to severe ROP: 7 (5%) in 32 < 33 weeks GA, 3 (2.4%) in 33 < 34 weeks GA, and 4 (2.5%) in 34 < 35 weeks GA. No treatment was required in 35 < 36 weeks GA., Conclusion: Late-preterm infants must be screened for ROP, especially those born in developing countries. Although rates of ROP development decrease as GA increases, infants born at 34 weeks of GA or younger, regardless of birth weight, should be examined at least once for ROP.

Purpose: To evaluate peripapillary choroidal thickness changes in contralateral eyes of patients who had undergone evisceration of their diseased eyes., Methods: In this retrospective study, peripapillary choroidal thickness parameters in 34 eyes of 34 patients who had undergone diseased-eye evisceration between March 2014 and May 2016 were evaluated using spectral domain optical coherence tomography. The scans were manually delineated to identify the principal surfaces of Bruch's membrane, the Bruch's membrane opening, and the anterior sclera. Peripapillary choroidal thickness was measured between the Bruch's membrane and the anterior sclera at increasing distance away from the Bruch's membrane opening. The mean peripapillary choroidal thickness values in the contralateral eyes of the patients and those of the control group were compared., Results: The mean peripapillary choroidal thickness was higher in the contralateral eyes of the patients compared with that of normal eyes at all distances from the Bruch's membrane opening., Conclusion: Increased peripapillary choroidal thickness was noted in the contralateral eyes of the patients, potentially resulting in a thicker choroid. Although further investigation is required to determine the cause, these findings indicate the presence of a compensatory factor in the contralateral eyes.

Purpose: This study aimed to share the results of patients who underwent anterior tarsal flap rotation combined with anterior lamellar reposition because of cicatricial upper eyelid entropion, and to determine the effectiveness and reliability of this surgical technique., Methods: Fifteen eyes of 11 patients (2 right eyes; 5 left eyes; and 4 bilateral eyes) on whom we performed anterior tarsal flap rotation surgery combined with anterior lamellar reposition because of cicatricial entropion were included in this study. The medical records of the patients were analyzed retrospectively, and the causes of cicatricial entropion as well as the preoperative and postoperative ophthalmic examination findings were recorded. Normal anatomical appearance and function of eyelid were considered to have been achieved., Results: The mean age was 59.81 ± 18 years. The mean follow-up period was 21.72 ± 14 months (range, 5-43 months). The causes of cicatricial entropion were postoperative cicatrices development due to multiple electrolyzes for trichiasis and/or distichiasis in 7 eyes, trachoma in 6 eyes, and trauma in 2 eyes. Irritation and watering were detected in all patients preoperatively, whereas corneal opacity and erosion were detected in 10 patients and epithelial erosion was detected in one patient. Full anatomical and functional success was achieved for all patients., Conclusion: Anterior tarsal flap rotation combined with anterior lamellar reposition in the repair of cicatricial entropion was found to be an effective and reliable alternative surgical procedure.

Background: To compare retinal nerve fiber layer thicknesses (RNFLT) of patients with or without Helicobacter pylori infection and to reveal the possible RNFLT changes after H. pylori eradication., Materials and Methods: Sixty-five eyes of 65 patients that tested positive for H. pylori (Group 1) and 48 eyes of 48 patients that tested negative for H. pylori (Group 2) were included. RNFLT analyses were performed with spectral-domain (SD) optical coherence tomography (OCT) in a total of five regions: the superior, inferior, nasal, and temporal quadrants and the average. Then, a comparison was made between groups. After H. pylori eradication in 38 patients, RNFLTs were compared with both pre-eradication values and Group 2., Results: The groups were similar in terms of age and gender. Temporal quadrant RNFLT was thinner in Group 1 than in Group 2 (P=.02). After H. pylori eradication, RNFLTs did not differ from pre-eradication values in Group 1 (P>.05 for all), whereas temporal quadrant RNFLT after H. pylori eradication was thinner compared to Group 2 (P=.03)., Conclusions: H. pylori may cause the localized defects on RNFL that are the early signs of glaucoma., (© 2017 John Wiley & Sons Ltd.)

Objectives: To evaluate the thicknesses of retinal nerve fiber layer (RNFL) and macula by fourier-domain (FD) optical coherence tomography (OCT) in non-diabetic patients with end-stage-renal-failure (ESRF) undergoing hemodialysis (HD)., Methods: This is a prospective and observational study. Both eyes of 20 patients receiving HD (group 1) and 34 control patients (group 2) were evaluated by FD-OCT. Macular and RNFL thicknesses were compared between groups and their correlation with age, duration of HD, and gender were examined. In group 1, macular and RNFL thicknesses were evaluated before and shortly after HD in the first day, first and sixth months.  , Results: In group 1, pre-HD temporal, inferior, average RNFL thicknesses were thinner than group 2. This thinning did not correlate with duration of HD, age and gender. Pre-HD macular thicknesses were thinner than group 2. These thinnings did not correlate with age, but the thinnings at superior, nasal and average thickness correlated negatively with duration of HD. Nasal, temporal, and average macular thicknesses were thinner in female patients. The thickenings of RNFL and macula that were observed in the after HD first day and first month did not showed consistency in the sixth month except superior quadrant RNFL., Conclusion: Macular and RNFL thicknesses of patients receiving HD were less than the normal population. Age has no effect on these thinnings. The duration of HD affects more than gender. Hemodialysis  session  causes a consistent increase in superior quadrant RNFL.

Background: The purpose of this study was to evaluate the results of tarsoaponeurectomy in patients with unsuccessful results after repetitive surgery or who developed post-traumatic blepharoptosis., Methods: The files of 107 patients (136 eyes) on whom surgery was performed between January 2010 and December 2014 due to blepharoptosis were scanned retrospectively. Among these patients, the files and operational notes of eight patients who underwent surgery through the method of tarsoaponeurectomy were examined in detail. The epidemiological data, indication for surgery, previous ptosis and/or eyelid surgeries and trauma histories, preoperative and postoperative measurement data (palpebral space (PS), margin reflex distance (MRD1, MRD2), levator muscle function (LMF)) of the patients were recorded. The follow-up time of the patients was 7 to 34 months with an average of 16 months., Results: A total of eight patients consisting of three females and five males were included in the study. The age range was 19 to 63 years with an average of 39 ± 16.2 years. Four patients had traumatic ptosis history whereas four patients had previous multiple levator procedure surgery history. Those patients with a history of ptosis had undergone surgery with levator procedure at least two times. Additionally, one patient had upper eyelid entropion, one had anophthalmic socket syndrome, and one had exposure keratopathy and traumatic dilated pupil. Seven patients had ptosis in the left eye whereas one patient had ptosis in the right eye. All patients were given a tarsoaponeurectomy as the basic surgical procedure while the patient with entropion was given a tarsal fracture and ear cartilage grafting as additional surgery. Two patients with vertical notching were also given a vertical blepharotomy through which a strip of tarsus was removed., Conclusions: Tarsoaponeurectomy is an alternative method for oculoplastic surgeons used to deal with patients on whom sufficient and desired results have not been achieved despite repetitive surgery and in post-traumatic cases where levator muscle and aponeurosis cannot be dissociated peroperatively.

Purpose: To compare the outcomes of external dacryocystorhinostomy (E-DCR) by using two different flap anastomosis patterns and skin incision types., Methods: This study included 79 patients (88 eyes) with lacrimal drainage system disorders who underwent E-DCR surgery. Fifty eyes of 44 patients (group A) underwent E-DCR by suturing anterior and posterior flaps (H-flap) of the lacrimal sac with curvilinear skin incision whereas in 38 eyes of 35 patients (group B) DCR was performed by suturing only anterior flaps (U-flap) with W skin incision., Results: The success rate was evaluated according to lacrimal patency and scar assessment scores. Patency was achieved in 78 patients (88.6%). In terms of groups, patency was 44 eyes (88.0%) in group A and 34 eyes (89.5%) in group B. There was no statistically significant difference in the success rates of lacrimal patency between the two groups. Further, there was no statistically significant difference concerning cutaneous scar scores., Conclusion: Our study suggests that anastomoses of only anterior flaps or both anterior and posterior flaps have similar success rates; suturing only anterior flaps is easier to perform and shortens the operative time. In addition, W skin incision is a reasonable alternative to curvilinear incision for reducing scar formation.

Purpose: To evaluate of functional and cosmetic effectiveness of lower eyelid sling technique with fascia lata graft in patients with lagophthalmos due to facial paralysis., Material and Method: Ten patients with a mean age of 55.1 ± 19.77 years who underwent lower eyelid sling surgery with a fascia lata graft between September 2011 and January 2014 were included in this prospective study. Preoperatively and postoperatively patients were evaluated in terms of corneal epithelial defects, Schirmer's test, and tear break-up time (TBUT). Cosmetically, vertical eyelid aperture, margin reflex distances 1 and 2 (MRD1 and MRD2) and scleral show were evaluated preoperatively and postoperatively., Results: One patient had facial paralysis on the right side whereas the other 9 patients had facial paralysis on the left side. Preoperatively, 3 patients were detected with corneal ulcer, whereas 7 patients were detected with persistent corneal epithelial defects localized in the lower half of the cornea. In the 3 patients with preoperative corneal ulcer, the ulcer recovered with corneal opacity, whereas in the 7 patients with punctate epitheliopathy, postoperative corneal transparency was obtained., Discussion: Lower eyelid sling technique with fascia lata graft is an effective technique for the repositioning of the lower eyelid and preventing the corneal complications.

Purpose: This study aims at comparing two different types of drainage tubes in conjunctivodacryocystorhinostomy, which are used for upper lacrimal system obstruction or damage, with respect to their respective postoperative problems and solutions., Methods: Nineteen eyes of 17 patients who underwent conjunctivodacryocystorhinostomy (CDCR) or conjunctivorhinostomy (CR) surgery with a Medpor coated tear drainage tube or silicon tube placement between October, 2010, and February, 2014, were included in this retrospective comparative study., Results: In the initial surgery, Medpor coated tear drainage tubes were used in 11 eyes by CDCR, whereas silicon tear drainage tubes were implanted into 2 eyes by CR and 6 eyes by CDCR. In group 1, proximal and distal obstructions developed postoperatively in 4 eyes, while 1 eye showed tube malposition and 3 eyes developed luminal obstruction by debris 3 times. In group 2, tube extrusion developed in 4 eyes, whereas tube malposition developed in 6 eyes and luminal obstruction by debris developed in 6 eyes at different times, for a total of 20 times., Conclusions: In our study, the most significant complication we observed in the use of silicon tear drainage tubes was tube extrusion,whereas the leading complication related to the use of Medpor coated tear drainage tubes was tube obstruction.

Aqueous outflow via the conventional outflow pathway is dependent on the pressure gradient between intraocular pressure (IOP) and episcleral venous pressure (EVP). Elevated IOP resulting from increased EVP is a well-known complication of arteriovenous fistulas, which are usually between the carotid artery and the cavernous sinus. Arteriovenous malformations usually occur spontaneously, after a trauma or from iatrogenic causes, and they manifest with findings of chemosis, dilatation of the conjunctival vessels, exophthalmos, and extraocular motility limitation. In this study, we present a case of elevated IOP due to facial arteriovenous malformations following a functional neck dissection surgery that caused intraocular pressure elevation.

Purpose. The aim of this study is to investigate the etiology and the clinical, microbiological, histopathological, and radiological findings of acquired dacryocystoceles. Methods. In this retrospective study, we reviewed the clinical records of 10 eyes of 8 patients with dacryocystoceles who underwent external dacryocystorhinostomy (DCR) surgery. Etiology, presenting symptoms and radiological findings as well as microbiological and histopathological assessment results and outcome were analyzed. Results. The records of 8 patients with dacryocystoceles were included in this study. In the histopathological evaluations of the samples collected from the lacrimal sac wall, chronic inflammation was found in all biopsied samples and fibrosis was observed in two histopathological evaluations. Computerized tomography (CT) imaging showed fluid collection separated from adjacent tissues by a thin rim, corresponding to dacryocystoceles in the sac. In the microbiological culture examination of samples collected from the fluid within the cyst, no bacterial growth in 5 eyes, gram-negative bacillus growth in 3 eyes, and gram-positive cocci growth in 2 eyes were found. Conclusions. Acquired dacryocystoceles were observed extremely rarely and a definite pathogenic agent could not be identified in any of the cases, either microbiologically or histologically, whereas chronic inflammation was detected in all cases in our study.
