RESUMO
AIM: To evaluate the efficacy, safety, structural and functional progression following the insertion of iStent inject ® implants in patients with open-angle glaucoma or ocular hypertension at a tertiary-level hospital. MATERIALS AND METHODS: A retrospective study included 98 eyes (57 males and 41 females) with open-angle glaucoma or ocular hypertension, which underwent iStent inject W® implantation (Glaukos, Corporation, CA) between December 2018 and December 2022. Differences in intraocular pressure (IOP), the number of hypotensive eye drops used, and structural and functional tests were assessed between preoperative values and subsequent reviews during a follow-up period of one (nâ¯=â¯98), two (nâ¯=â¯55), and three years (nâ¯=â¯15) after surgery. RESULTS: Among the 98 eyes studied, 85% were diagnosed with open-angle glaucoma (50% mild, 32% moderate, and 18% severe) and 15% with ocular hypertension. There was a statistically significant reduction in IOP compared to preoperative values for all visits except the 1-month (pâ¯=â¯0.36) and 3-year (pâ¯=â¯0.39) visits. Visual acuity increased from 0.39⯱â¯0.25 to 0.72⯱â¯0.24 (pâ¯<â¯0.01), considering that a significant portion of the interventions included cataract surgery. Before surgery, 66% of the sample used 2 or more hypotensive medications. Post-surgery, the number of hypotensive medications decreased (from 1.88⯱â¯0.84 to 0.21⯱â¯0.59 at 3 years) (pâ¯<â¯0.01), with an 88.9% reduction in the number of medications over three years. After surgery, 75% of cases did not require any medication. Regarding structural and functional tests, thickness of retinal nerve fiber layers (RNFL (pâ¯=â¯0.35), excavation / papilla ratio E/P (pâ¯=â¯0.31), visual function index (VFI (pâ¯=â¯0.06), and deviation mean (MD (pâ¯=â¯0.06) showed no statistically significant differences post-intervention. However, standard deviation of the pattern (DSM) did exhibit differences, decreasing from 5.46⯱â¯4.03â¯dB to 5.34⯱â¯3.48â¯dB (pâ¯=â¯0.02). CONCLUSION: The results of this study suggest that the iStent inject W® technique constitutes an effective and safe option for tension control and glaucoma treatment.
RESUMO
INTRODUCTION: Burnout syndrome refers to the physical and psychological fatigue suffered by workers as a result of their professional activity. It has three main characteristics: emotional exhaustion, depersonalization and lack of personal fulfillment. PURPOSE: To determine the prevalence of burnout syndrome among Andalusian ophthalmologists, both consultants and residents, analyzing its relationship with several sociodemographic variables. MATERIAL AND METHODS: Descriptive cross-sectional study. All the sociodemographic variables were included in a Google® form together with the standardized questionnaire Maslach Burnout Inventory-Human Services Survey (MBI-HSS). This form was sent to the Andalusian ophthalmological community by different electronic means (Andalusian Society of Ophthalmology, instant messaging mobile apps, etc.). RESULTS: One hundred fourty two ophthalmologists answered the form, with a similar distribution by sex and a mean age of 43.77 years, with 67.1% of them meeting criteria of burnout syndrome. Its prevalence was higher among young ophthalmologists, with fewer years of clinical practice, divorced/separated, those with fewer children, belonging to centers in the province of Huelva, workers in rural/regional areas, those with exclusive public activity, consultants with temporary contracts and four-year residents. Regarding subspecialties, its prevalence was higher among those who focused on cornea-ocular surface-refractive surgery. CONCLUSIONS: This study quantify for the first time in Andalusia the prevalence of burnout syndrome among ophthalmologists. The fact that two thirds of the analyzed sample meet criteria proves the need to implement improvements in the clinical and professional conditions of our group.

OBJECTIVES: To determine the prevalence of ophthalmological emergency visits to two tertiary hospital in all age groups during years 2014 and 2015. METHODS: All patients who attended Ophthalmological Emergency Department from 1 January 2014 to 31 December 2015 were included in the study. The demographic variables studied were gender, age, place of origin, time of arrival, day of the week, month and year of the visit, the diagnosis, destination on discharge, total time of the visit and priority. Pathologies were categorised using codes from ICD-9, CM. RESULTS: A total of 39,869 visits were made between 2014 and 2015. Emergency consultations were more frequent among women, on Mondays, and from April to June. The mean age of the patients was 46.24years old, and 73.42% of visits were classified as non-emergencies. The most frequent pathology was conjunctivitis (17.28%), followed by keratitis (15.31%), and vitreous detachment (5.37%). The pathology that led to more hospital admissions was orbital cellulitis (23%). The majority of patients (94.85%) were sent to their place of residence after the visit. CONCLUSIONS: Given that the great majority of Ophthalmological Emergency visits are categorised as non-emergencies, measures need to be set up in order achieve a more effective care focused on emergency pathology without using unnecessary resources.

BACKGROUND AND OBJECTIVE: The diagnosis of retinal dystrophies is complex and is based on complete ophthalmological study, genetic study and electrophysiological studies (EPS). In this study, we intend to evaluate the role of electrophysiological and medical tests in the diagnosis of retinal dystrophies. MATERIAL AND METHODS: A retrospective observational study was conducted on 50 selected patients that attended the Neurophysiology Department of the University Hospital Virgen Macarena. An analysis was made of the variables that included, gender, age, referral hospital, reason for which the EPS was requested, applied EPS, genetic study, presumed diagnosis, and definitive diagnosis after EPS. A classification system was subsequently developed, which gives each case a value between 0 and 2, depending on the contribution of the electrophysiological tests to the final diagnosis. RESULTS: The mean age was 44.34 ±18.03 years (60% women). Retinitis pigmentosa (24%), optic neuropathy (12%), and Stargardt's disease (8%) were the most frequent diagnoses. The EPS modified the presumed diagnosis in 48% of the cases, confirmed the diagnosis in 44%, and did not provide any useful information in 8%. The contribution of the EPS was greater in patients seen in the HUVM and when requested by findings in the examination (P=.001). The false positives in the diagnosis of retinal dystrophy were 60% in patients not evaluated by the University Hospital Virgen Macarena. CONCLUSIONS: Electrophysiological test and specialised management of patients with retinal dystrophies play an important role in the diagnosis of these conditions.

PURPOSE: To evaluate the usefulness of silicone-fluorsilicone copolymer oil (SiFO) as an intraoperative tool and a vitreous substitute in vitreoretinal surgery. METHODS: Handling properties of SiFO were tested and compared with those of perfluorooctane (PFO). The transparency of both substances was measured by spectrophotometry and subjectively assessed. Their tendency to dispersion was observed during injection in balanced saline solution (BSS) and after mechanized and manual shaking. Ease of injection and aspiration through small-gauge instruments was evaluated. Ocular tolerance to SiFO and PFO was studied after intravitreal injection in rabbit eyes: intraocular pressure, anterior segment inflammatory response and dispersion were evaluated, and a histopathological study was performed. RESULTS: Injection and aspiration of SiFO were more difficult than those of PFO because of its higher viscosity. PFO dispersed progressively into small droplets as early as two days after intravitreal injection, whereas SiFO remained as a single bubble for 14 days. Histopathologically both substances induced an inflammatory response over the inferior retina, with microvacuolated macrophages and foreign body giant cells, which were larger in eyes wearing SiFO. CONCLUSIONS: SiFO may be useful as an intraoperative tool, although its main drawback is a more difficult injection and aspiration compared to PFO. It has been well tolerated as a short-term vitreous substitute, but further clinical studies are needed.

PURPOSE: To establish the incidence, evolution and final visual outcome of corneal epithelial complications after vitrectomy in a consecutive series performed throughout a period of one year. METHODS: 195 consecutive medical records of patients vitrectomized in 2001 have been retrospectively reviewed. Patients were clinically evaluated the day after vitrectomy, during the first week, and then weekly for 3 months (minimum follow-up). Functional results have been established at the end of this period. RESULTS: 12 out of 195 eyes developed corneal epithelial complications after surgery (6.1%). Eight cases were diagnosed of persistent epithelial defect (4.1%), and four cases (2%) of necrotizing herpetic keratitis. Six out of 12 were diabetic. Corneal epithelial complications affected 10.5% of diabetic and 4.3% of non-diabetic patients (p=0.10). The majority of persistent epithelial defects healed without sequelae in less than two months. Herpetic keratitis required between 3 to 4 months to heal and caused corneal scarring in all cases. CONCLUSIONS: Persistent corneal epithelial defects after vitrectomy are a relatively frequent complication, mainly in diabetic patients. Recurrence of herpetic keratitis must also be kept in mind. This finding has not been previously reported and needs further studies.

PURPOSE: To establish the incidence and characteristics of iatrogenic retinal breaks occurring during vitrectomy and to propose a protocol for their management. METHODS: Retrospective study of 195 consecutive vitrectomies performed in 2001. Minimum follow up was 3 months for all cases. RESULTS: 13 patients with iatrogenic retinal breaks (6.6%) have been detected. In 8 cases the breaks affected the peripheral retina, in 4 cases they were located in the posterior pole and there was one retinal dialysis. In 4 cases there were more than one retinal break. 9 patients (70%) were vitrectomized for diabetic retinal complications. In 12 cases, the breaks were detected during surgery and treated with endolaser and/or cryoretinopexy (3 cases located inferiorly). Nevertheless 7 cases (54%) developed a retinal detachment, 2 of which could be reattached. CONCLUSIONS: Among iatrogenic retinal breaks produced during vitrectomy, the peripheral ones are slightly more frequent than the breaks in the posterior pole. Iatrogenic breaks occur more frequently in diabetic patients, having a bad prognosis and often developing a retinal detachment despite endolaser or cryoretinopexy.

CLINICAL CASES: We report two cases of SO (sympathetic ophthalmia) among 1,456 vitrectomies and 255 silicone oil injections performed since 1990. In both patients intraocular silicone oil was used. Both cases were clinically documented and one pathologically demonstrated. DISCUSSION: No cases were reported among vitrectomies without silicone oil. We found a longer delay between injury and the onset of the disease in comparison to the literature. Pathological findings confirmed a foreign body granulomatous reaction. Chronic inflammation caused by silicone oil might be involved in the development of SO. Larger series are necessary to establish a possible relationship between silicone oil and SO.
