RESUMO
PURPOSE: This study aimed to describe the impact of COVID-19 pandemic on the presentation characteristics, timings, and surgical decisions for primary rhegmatogenous retinal detachment (RRD). METHODS: A historical cohort including all patients who presented to the Surgical Retina Section at Centro Hospitalar Universitário do Porto (CHUPorto), over a 2-year period, was recruited and divided into 2 groups: pre-COVID and COVID groups. The onset of the COVID-19 pandemic was recorded as starting on March 18, 2020, the same day the first pandemic-related lockdown came to effect in Portugal. RESULTS: This study enrolled 449 eyes of 443 patients: 272 in the pre-COVID group and 177 in the COVID one. Of the patients, 63.6% were male, and the mean ± SD age was 63.0 ± 13.2 years (range 13-92 years). Of the eyes, 55.5% (n = 151) presented with macular detachment in the pre-COVID group compared with 66.9% (n = 119) in the COVID group (odds ratio [OR] 1.62; 95% confidence interval [CI]: 1.09-3.86; p = 0.016). The time from symptom onset to hospital admission (p = 0.021) and from admission to surgery (p < 0.001) was longer in the COVID era. In the COVID period, silicone oil (OR 2.03, 95% CI: 1.09-3.79, p = 0.025) and C3F8 gas (OR 2.42, 95% CI: 1.57-3.71, p < 0.001) were used more often. No differences in anatomical success or final visual acuity were found. CONCLUSIONS: The lockdown due to COVID pandemic affected the epidemiology of RRD. The services must adapt to the novel reality and produce backup plans for similar events. Despite the contingencies, the final results were not different between groups.

PURPOSE: To assess the outcomes of vitrectomy with or without cataract surgery for the treatment of idiopathic ERM in phakic eyes and evaluate predictors of functional and anatomical outcomes. METHODS: Retrospective cohort of consecutive phakic ERM eyes distributed in three groups: a) combined (phacovitrectomy) group, b) PPV-only group, and c) consecutive group (PPV followed by cataract surgery). Main outcomes were final visual acuity (VA) and cystoid macular edema (CME) occurrence. Potential predictors of VA or CME included clinical variables and SD-OCT parameters. RESULTS: A total of 108 eyes were included in this study. There were no differences in the final VA between consecutive and combined groups (0.22 vs 0.10 logMAR, p = 0.851). Twelve eyes from the combined group (23%) and one eye from the PPV-only group presented CME (p = 0.001). There were no differences between postoperative CME occurrence in combined versus consecutive group (12 vs 7, p = 0.38). The presence of cotton-ball sign predicted the development of CME [OR 2.86 (95%CI 1.01-8.18), p = 0.049] while separated ERM-ILM complex was found to be protective [OR 0.25 (95%CI 0.08-0.77), p = 0.015]. CONCLUSIONS: Functional and anatomical results of PPV with ERM and ILM peeling combined with cataract surgery was equivalent to the consecutive procedure, with both strategies being effective. Separated ERM-ILM complex has prognostic value in these patients, as its presence at baseline was found to be protective for postoperative CME.

PURPOSE: To evaluate the ellipsoid zone (EZ) structural recovery, hole closure rate, and visual acuity improvement after inverted internal limiting membrane (ILM) flap technique. METHODS: Retrospective cohort of eyes affected by idiopathic macular holes (MH) that underwent pars plana vitrectomy combined with inverted ILM flap technique in a tertiary center, over an 8-year period (2011-2019). The main outcomes were the postoperative qualitative analysis of EZ structure on spectral-domain optical coherence tomography, hole closure rate, and best-corrected visual acuity (BCVA) improvement of ≥ 0.3 units in the logarithm of minimal angle of resolution (logMAR) scale. RESULTS: Our study included 76 eyes of 72 patients; 65% were female, with a mean age of 70 ± 8 years-old. Median (range) follow-up was 21 (3-92) months. Hole closure rate was 92%. Structural defects in EZ were observed in 66% of closed holes (EZ atrophy in 33%, EZ disruption in 22%, and EZ thinning in 11%). The mean final BCVA was 0.5 ± 0.4 logMAR (Snellen 20/63), but visual acuity improvement occurred in 80% of the eyes. Final BCVA was significantly worse in eyes with EZ atrophy compared with eyes with EZ disruption (0.75 vs. 0.36 logMAR, p = 0.004) and EZ thinning (0.75 vs. 0.32 logMAR, p = 0.015). In multivariate regression, minimum linear diameter (OR 1.01; IC 95% 1.01-1.02) independently predicted a final BCVA (logMAR) < 0.3 units. CONCLUSION: Inverted ILM flap technique provided a hole closure rate above 90%, similar to previous studies. Although the modest value of the final BCVA, a significant visual acuity improvement occurred in most eyes. Structural defects of EZ were found in more than half of closed MHs after surgery. Evidence of postoperative retinal atrophy was associated with a worse visual outcome.

Purpose: To address if corneal biomechanical behavior has a predictive value for the presence of glaucomatous optical neuropathy in eyes with high myopia. Patients and Methods: This observational cross-sectional study included 209 eyes from 108 consecutive patients, divided into four groups: high myopia and primary open-angle glaucoma (POAG) - HMG, n = 53; high myopia without POAG - HMNG, n = 53; non-myopic with POAG - POAG, n = 50; non-myopic and non-POAG- NMNG, n = 53. Biomechanical assessment was made through a Scheimpflug-camera-based technology. Receiver operating characteristic curves were made for the discrimination between groups. Multivariable logistic regression models were performed to address the predictive value of corneal biomechanics for the presence of glaucoma. Results: Areas Under the Receiver Operating Characteristic (AUROCs) above 0.6 were found in 6 parameters applied to discriminate between HMG and HMNG and six parameters to discriminate between POAG and NMNG. The biomechanical models with the highest power of prediction for the presence of glaucoma included 5 parameters with an AUROC of 0.947 for eyes with high myopia and 6 parameters with an AUROC of 0.857 for non-myopic eyes. In the final model, including all eyes, and adjusted for the presence of high myopia, the highest power of prediction for the presence of glaucoma was achieved including eight biomechanical parameters, with an AUROC of 0.917. Conclusion: Corneal biomechanics demonstrated differences in eyes with glaucoma and mainly in myopic eyes. A biomechanical model based on multivariable logistic regression analysis and adjusted for high myopia was built, with an overall probability of 91.7% for the correct prediction of glaucomatous damage.
RESUMO
Purpose: To evaluate the agreement between conventional fundus photography (CFP) and multicolor fundus imaging (MFI) for the detection of lesions of diabetic retinopathy (DR) and retinal vein occlusion (RVO). Methods: Cross-sectional analysis of eyes with DR or RVO who underwent CFP and MFI. All images were independently analyzed by two observers (O1 and O2), and the evaluated lesions were classified as "present" or "absent". Then, a paired comparison between both exams of the same eye was performed, to assess which made it easier to detect the lesions. Results: Considering DR, the agreement was substantial for cotton wool spots and photocoagulation scars for both observers (O1: κ=0.75 and κ=0.67; O2: κ=0.71 and κ=0.64, respectively) and for hard exudates for O1 (κ=0.80). These lesions were detected more frequently on MFI. Regarding RVO, the agreement was considered substantial for venous sheathing by O1 (κ=0.64) and moderate for optociliary shunts by O2 (κ=0.60). Optociliary shunts were detected more frequently in CPF by both observers and venous sheathing on MFI by O1. For microaneurysms, retinal hemorrhages, retinal neovascularization, and proliferative membranes, in DR, and retinal hemorrhages, venous engorgement, and retinal neovascularization in RVO, the agreement was almost perfect (κ>0.82). In the paired analysis, both observers considered that, in DR, microaneurysms and retinal hemorrhages were easier to detect on CFP and that retinal neovascularization, cotton wool spots, and photocoagulation scars were easier to identify on MFI. Regarding RVO, optocilliary shunts were easier to identify on CFP and venous engorgement on MFI. Conclusion: The agreement of MFI and CFP was substantial to almost perfect for most lesions. MFI seems better to detect cotton wool spots and photocoagulations scars in DR and venous sheathing in RVO. Optocilliary shunts seem easier to detect on CFP.
RESUMO
PURPOSE: To report the case and multimodal imaging findings of a healthy young woman who developed paracentral acute middle maculopathy 9 weeks after COVID-19. METHODS: Case report. Ultra-widefield fundus photography, macular spectral domain optical coherence tomography, fluorescein angiography, and optical coherence tomography angiography were performed. RESULTS: A 36-year-old woman went to the emergency department with sudden, painless, left eye vision loss. The only relevant medical history was COVID-19 9 weeks before. The best-corrected visual acuity was 20/200, a left eye relative afferent pupillary defect was present, and superficial hemorrhages throughout the macular area and peripheral retina were found. Nearly 4 hours after admission, the left eye best-corrected visual acuity recovered to 20/20 without relative afferent pupillary defect. Five days after presentation in the emergency department, the patient returned with recurrent left eye vision loss, with spontaneous recovery within 12 hours. Macular spectral domain optical coherence tomography revealed hyperreflectivity of the inner plexiform and inner nuclear layers, and the diagnosis of paracentral acute middle maculopathy was established. The patient started oral acetylsalicylic acid and oral prednisolone. The patient did not report any new episodes of vision loss, and there was a progressive resolution of abnormal fundus findings. CONCLUSION: SARS-CoV-2 infection increases the risk of vascular thrombotic events with possible involvement of the retinal circulation, and paracentral acute middle maculopathy may present as a possible complication. Ophthalmologists should be able to recognize it promptly through multimodal imaging findings.

BACKGROUND: The main options for intraocular lens (IOL) placement without capsular bag support and/or zonular weakness are iris-fixated IOL and scleral-fixated IOL (SFIOL). PURPOSE: To describe the surgical technique and the outcomes of intrascleral knotless zigzag suture fixation of Akreos AO60 foldable IOL. METHODS: Retrospective cohort study of consecutive cases. RESULTS: Ninety-nine eyes of 92 patients were retrospectively studied. The mean age was 72.1±15.2 years (range 18-94), and the median follow-up duration was 19.5 months (range 3-81). The best-corrected visual acuity improved from a mean±SD of 1.34±0.70 logarithm of the minimum angle of resolution (logMAR) units at baseline to 0.49±0.56 logMAR at the end of follow-up (p<0.001). The mean±SD final SE was -1.24±1.82 diopters. The mean±SD prediction error was -0.51±1.16 diopters. The overall perioperative complications rate was 44.4% (n=44). The rate of complications requiring invasive treatment was 19.2% (n=19). The most common perioperative complications were ocular hypertension (OHT, 20.2%, n=20), and cystoid macular edema (CME, 15.2%, n=15). The rate of IOL dislocation was 7% (n=7). CONCLUSION: This knotless technique avoids the risks of haptics fixation but is more prone to IOL dislocation in cases of suture deterioration. Past ophthalmic history needs to be carefully considered in candidates who underwent SFIOL implantation.
RESUMO
Background: Understanding how strabismus impacts a child's quality of life, as well as their families, should be an important key to guide treatment, not only from the ophthalmological point of view but also regarding psychological and social aspects, which are fundamental for a healthy and harmonious development. Methods: A cross-sectional study was performed to evaluate the functional vision and eye-related quality of life (ER-QOL) in a population of children with strabismus submitted or not to corrective surgery, using the recently developed Pediatric Eye Questionnaire (PedEyeQ) and to compare with age and gender-matched visually normal children. The PedEyeQ was applied to non-operated children with strabismus (n = 18), operated children with strabismus (n = 24), and visually normal children (n = 21). This instrument is composed of 3 components (Child, Proxy, and Parent) and has different versions according to the child's age (0-4, 5-11, or 12-17 years-old versions). Clinical data such as age, type of strabismus, angle of deviation, amblyopia, occlusion treatment, and surgical outcome were also recorded. Results: All PedEyeQ domain scores were significantly lower in children with strabismus compared with visually normal children, except the Child "functional vision" domain. Children with strabismus with successful corrective surgery had significantly lower scores in many domains of the Child, Proxy, and Parent components, compared with visually normal children. Conclusion: This study showed that strabismus has an important impact on affected children and their families, as assessed by PedEyeQ. Interestingly, children with prior successful corrective strabismus surgery had worse PedEyeQ scores compared to visually normal children. Educational programs and psychosocial rehabilitation interventions should be implemented in children with strabismus and their families.
RESUMO
BACKGROUND: To evaluate biomechanical parameters of the cornea provided by Corvis ST in patients with ocular hypertension, primary open-angle glaucoma, and amyloidotic glaucoma and to compare with healthy controls. METHODS: This was a cross-sectional study of patients with ocular hypertension, primary open-angle glaucoma, and amyloidotic glaucoma that underwent Corvis ST imaging. Primary outcome was the comparison of corneal biomechanical parameters between study groups after adjusting for age, gender, Goldmann intraocular pressure (GAT-IOP), and prostaglandin analogues medication. Secondary outcome was the comparison of different IOP measurements in each group. RESULTS: One hundred and eighty-three eyes from 115 patients were included: 61 with primary open-angle glaucoma, 32 with amyloidotic glaucoma, 37 with ocular hypertension and 53 were healthy controls. Amyloidotic glaucoma group had smaller radius (p=0.025), lower deflection amplitude at highest concavity (p=0.019), and higher integrated radius (p=0.014) than controls. Ocular hypertension group had higher stiffness parameter at first applanation (p=0.043) than those with primary open-angle glaucoma, and higher stress-strain index (p=0.049) than those with amyloidotic glaucoma. Biomechanically corrected intraocular pressure was significantly lower than Goldmann intraocular pressure in group with primary open-angle glaucoma (p=0.005) and control group (p=0.013), and Goldmann intraocular pressure adjusted for pachymetry in group with primary open-angle glaucoma (p=0.01). CONCLUSION: Eyes with amyloidotic glaucoma have more deformable corneas, while eyes with ocular hypertension have less deformable corneas. These findings may be linked to the susceptibility to glaucomatous damage and progression. There were significant differences between Goldmann applanation tonometry and biomechanically corrected intraocular ocular pressure provided by Corvis ST.
RESUMO
Surgical treatment is generally necessary to repair full-thickness macular holes (FTMH). Although vitrectomy with or without internal limiting membrane (ILM) peeling remains the standard surgical technique, the inverted ILM flap procedure has increasingly assumed a role in the primary surgical repair of FTMHs. Some vitreoretinal surgeons reserve this technique to treat large or myopic holes, whereas others use it routinely in all cases. This paper is a comprehensive review of the current scientific evidence on the anatomical and functional outcomes of the inverted ILM flap technique in the repair of macular holes, following the International Vitreomacular Traction Study (IVTS) group classification.
RESUMO
Hereditary gelsolin amyloidosis is a rare subtype of hereditary systemic amyloidosis. An old male presented with the characteristic triad of symptoms, including bilateral facial palsy, cutis laxa, and corneal lattice amyloidosis. The diagnosis was confirmed by the detection of the mutation in gelsolin gene located on chromosome 9. Although the presenting symptoms were highly suggestive of the disease, reports of severe ocular involvement are scarce in the literature.
RESUMO
Vitamin D may be implicated in the pathophysiology of several ocular diseases, but its role in age-related macular degeneration (AMD) remains uncertain. We sought to review systematically the existing evidence to evaluate the association between serum 25-hydroxyvitamin D 25(OH)D levels and AMD. A four-database search (PubMed, ISI Web of Science, Cochrane, and Scopus) was performed from inception to May 2020 using the MeSH terms: ("Macular Degeneration" OR "Age-related macular degeneration" OR "Retinal degeneration" OR "Macula lutea") AND ("Vitamin D" OR "Ergocalciferols" OR "Cholecalciferol" OR "25-Hydroxyvitamin D"). Random-effects meta-analyses were performed to compute 1) the standard mean difference in 25(OH)D concentration between AMD and non-AMD patients and 2) the AMD risk according to serum 25(OH)D levels. Eighteen observational studies enrolling 75,294 patients after a selection process among 375 original abstracts were selected. No significant differences were found, but there appears to exist a trend for late AMD among subjects with a serum 25(OH)D level below 50 nmol/L (odds ratio, 1.8; 95% confidence interval: 1.00-3.24, P = 0.05). There is no clear evidence of a definitive association between serum 25(OH)D and AMD risk, mainly due to heterogeneity in study procedures and lack of longitudinal designs.

PURPOSE: The primary objective of this study was to better understand the epidemiological risk factors associated with severe eye injury of patients and the secondary objective was to evaluate functional outcomes of these severe eye injuries. METHODS: A retrospective, noncomparative cohort study of severe ocular trauma, in patients assessed in an emergency room from January 2004 to December 2018 at Centro Hospitalar Universitário do Porto was performed and statistically analyzed. RESULTS: This study included a total of 751 patients (758 eyes) suffering ocular trauma. Men had a higher rate of ocular trauma than women (81.4% vs 18.6%). The mean age was 48.9 years old. The most common types of injury were rupture (33.8%) and penetrating (20.9%). Work-related accidents were responsible for 19.3% of injuries. Home was the most common location of trauma (46.3%). In 8.8% of trauma the best corrected visual acuity at presentation was superior to 20/40 while in 6.5% of cases no light perception (NLP) was registered. In 44.8% of trauma the best corrected visual acuity at last follow-up visit (BCVAF) was superior to 20/40 while in 15.7% of cases NLP was registered. CONCLUSION: The epidemiological high-risk factors identified were: adult males, economic crisis, home, blunt objects in man and falls in woman. Future primary prevention should take into account these factors. This study also demonstrated an important visual impairment associated with severe ocular trauma, even with timely surgical treatment, with BCVAF of NLP in 15.7% of cases.

BACKGROUND: Cystoid macular edema (CME) due to Irvine-Gass syndrome (IGS) is one of the common causes of painless visual impairment post-cataract extraction. The treatment of recurrent cases remains unstandardized. OBJECTIVE: To evaluate the effectiveness and safety of fluocinolone acetonide intravitreal implant (0.2 µg/day; ILUVIEN®) in the off-label treatment of recurrent CME due to IGS. METHODS: Retrospective 36-month case series in the Ophthalmology Department of Centro Hospitalar Universitário do Porto, Portugal. Consecutive eyes of patients with recurrent cystoid macular edema due to Irvine-Gass syndrome who underwent a single intravitreal injection of fluocinolone acetonide intravitreal implant were included. Best-corrected visual acuity (logMAR), central macular thickness (µm) and safety (intraocular pressure, mmHg) at baseline and at 6, 12, 24 and 36 months post-administration of the fluocinolone acetonide intravitreal implant were recorded. RESULTS: Five eyes from three patients were included. The duration of cystoid macular edema was 67.8±25.9 months and all five eyes received more than 2 intravitreal injections of a corticosteroid (triamcinolone and/or dexamethasone implant) prior to fluocinolone acetonide intravitreal implantation. At baseline (median - interquartile range), best-corrected visual acuity was 0.3-0.3; central macular thickness was 492.0-38.0; and intraocular pressure was 16.0-0. By Month 36, best-corrected visual acuity was 0.4 -0.3; central macular thickness was reduced to 369.0-324.0 and intraocular pressure was 17.0-3.0. Four of five eyes had increased intraocular pressure and were managed with intraocular pressure-lowering eye drops. CONCLUSION: We report improved functional and anatomical outcomes after treatment with fluocinolone acetonide intravitreal implant, indicating its use as a therapeutic alternative in recurrent cases of cystoid macular edema due to Irvine-Gass syndrome. Additionally, in eyes with suboptimal response to intravitreal therapies, fluocinolone acetonide intravitreal implant may provide longer recurrence-free periods with reduced treatment burden.
RESUMO
PURPOSE: To characterize a population of high myopes with myopic traction maculopathy (MTM), to assess their retinal function, and to correlate it with anatomic status. PATIENTS AND METHODS: This was an observational cross-sectional study including 50 eyes from 27 patients. Demographic and clinical data were analyzed. Macular structure was assessed with spectral domain optical coherence tomography (SD-OCT, Heidelberg®) and macular function was studied with Microperimeter MP-3, NIDEK®. RESULTS: The average for central foveal thickness (CFT) and choroid thickness (CT) was 213±151 µm and 36±23 µm, respectively, in a total of 50 eyes from 27 patients. In the microperimetry analysis, the average sensitivity on the foveal-centered 12º polygon (CPS) was 14.37±9.1 dB. CT was negatively associated with the bivariate contour ellipse areas (BCEA) 1 (r=-0.314; p=0.034), 2 (r=-0.314; p=0.034), and 3 (r=-0.316; p=0.033). CPS had a strong positive correlation with best-corrected visual acuity (BCVA) (r=0.661; p=0.000). We found a trend to worse microperimetric results in eyes with schisis (n=19) (p>0.05) but eyes with atrophic areas (n=33) presented significant inferior CPS (p<0.001). The presence of staphyloma showed significant impact on macular sensitivities in eyes with areas of macular atrophy/fibrosis (p<0.05). CONCLUSION: Macular microperimetry analysis can have a role as part of a multimodal anatomo-functional assessment for a more precise characterization of the high myopic patients with MTM, optimizing medical and surgical decisions.
RESUMO
AIM: Diabetic retinopathy staging system and progression predictors are soon to be considered insufficient for ophthalmologic practice. Given the growing evidence of the role of choroidal dysfunction, our purpose was to assess choroidal vascular changes with intravitreal ranibizumab (RBZ) treatment in diabetic macular edema (DME). METHODS: This was a prospective longitudinal cohort study. The study included DME eyes, grouped in vitrectomized (group 1) and non-vitrectomized (group 2) eyes, submitted to RBZ in a pro re nata regimen, with 24 weeks of follow-up. Main outcome measures such as central subfield foveal thickness (CFT), choroidal thickness (CT), and choroidal vascular index (CVI) were obtained from structural OCT, and choriocapillaris flow density (CCD) was obtained from OCT angiography and analyzed before and after treatment. RESULTS: Thirty-one patients were included, 10 eyes in group 1 and 24 eyes in group 2. The mean number of injections was 5.18 (range 2-6). Globally, there was an improvement in BCVA (+4.3 ETDRS letters, p=0.004) and CFT (-84.6 µm, p<0.001) with no changes in CT, CVI, or CCD (p>0.05). When considering only group 2, there was a significant decrease in CT (p=0.033) and a significant increase in CCD (p=0.010) 6 months after treatment, with no differences in CVI (p=0.111). Baseline CVI was correlated with visual acuity at week 24 both globally (r=0.406, p=0.029) and in group 2 (r=0.604, p=0.004). CONCLUSION: In non-vitrectomized eyes, choriocapillaris blood flow improves with RBZ. Baseline CVI may correlate with visual function after RBZ. ClinicalTrials.gov NCT04387604.
RESUMO
INTRODUCTION: The purpose of this study was to provide objective and real-life data concerning the impact of the COVID-19 pandemicon ophthalmology residency training in Portugal. MATERIAL AND METHODS: Descriptive survey-based study applied to current Portuguese ophthalmology residents (n = 80 eligible). RESULTS: Seventy-five residents participated (94% response rate). All except one (99%) admitted a change in their routine clinical practice during the pandemic, and most (89%) continued to be engaged in ophthalmology department duties. Twenty-five percent were deployed to COVID-19 units, which was combined with ophthalmological activities in about half of them (47%). A significant proportion of participants stated that they were enrolled in the following ophthalmological activities: emergency/inpatient care (87%), outpatient visits (73%; general 70% vs subspecialty 29%), and surgical procedures (64%). Twenty-five percent did not assist in any outpatient visits and 36% did not participate in any surgical procedures. On a scale from 1 (no impact) to 5 (maximum impact), most participants classified their perceived negative impact of the pandemic on the training program as 3 (24%), 4 (40%), or 5 (27%). Participants highly agreed with the extension of the residency program (80%) in order to to make up for training disruption. DISCUSSION: Most trainees provided ophthalmological care during the pandemic. However, those clinical activities were essentially related to general and emergency care. Surgical experience was significantly curtailed. As such, strategies are needed to guarantee a high-quality learning process. Further studies are required to develop an international perspective on how ophthalmology training programs have been affected so that educational organizations can make recommendations regarding standardized adjustments to training programs. CONCLUSION: The COVID-19 pandemic has significantly impacted the training of ophthalmology residents nationwide.
Introdução: Este estudo teve como objetivo avaliar o impacto da pandemia COVID-19 no internato de Formação Específica de Oftalmologia em Portugal. Material e Métodos: Estudo descritivo dos resultados obtidos de um questionário aplicado a todos os internos de Formação Específica de Oftalmologia em Portugal (n = 80). Resultados: Setenta e cinco internos participaram no estudo (taxa de resposta de 94%). Excetuando um caso, todos (99%) admitiram alteração da sua prática clínica durante a pandemia, e a maioria (89%) manteve atividades clínicas no seu serviço de Oftalmologia. Vinte e cinco porcento foram integrados em unidades COVID-19, e metade desses inquiridos (47%) desempenharam concomitantemente atividades no âmbito da oftalmologia. Uma percentagem significativa dos inquiridos referiu estar envolvido nas seguintes atividades clínicas oftalmológicas: serviço de Urgência/consultas internas (87%), consultas externas (73%: geral 70% vs subespecialidade 29%), e cirurgias (64%). Vinte e cinco porcento não participaram em consultas externas, e 36% em procedimentos cirúrgicos. Numa escala de 1 (sem impacto) a 5 (máximo impacto), a maioria dos inquiridos classificou o impacto percecionado da pandemia no internato de Formação Específica de Oftalmologia em 3 (34%), 4 (40%) e 5 (27%). Oitenta porcento dos inquiridos enumerou a extensão do período do internato de Formação Específica como uma medida a adotar para minimizar o impacto negativo da pandemia. Discussão: A maioria dos internos mantiveram-se a desempenhar atividades clínicas no seu serviço de Oftalmologia, principalmente no âmbito da oftalmologia geral e de urgência. O desempenho de atividade cirúrgica foi largamente afetado. São necessárias estratégias adaptativas para garantir a continuação adequada da formação dos internos. Futuros estudos noutros contextos geográficos permitirão perceber de que forma os programas de formação em oftalmologia estão a ser afetados ao nível internacional, para que as organizações educacionais possam elaborar recomendações. Conclusão: A pandemia COVID-19 teve um impacto significativo no internato de Formação Específica de Oftalmologia em Portugal.

A 76-year-old male presented with a small hyperreflective density in the outer nuclear layer with subtle retinal pigment epithelium (RPE) elevation and few intraretinal cysts on spectral-domain optical coherence tomography (SD-OCT). Optical coherence tomography angiography (OCTA) confirmed the presence of a tuft-shaped intraretinal neovascular lesion. SD-OCT performed 2 months before showed a smaller RPE elevation at the same location without intraretinal fluid. A 79-year-old male presented with a small hyperreflective density in the outer retina surrounded by scant intraretinal fluid on SD-OCT and a bright vessel on OCTA, suggesting early-stage type 3 neovascularization. SD-OCT performed 2 months before showed a smaller hyperreflectivity at the same location, without intraretinal fluid. An 84-year-old female presented with hyperreflective foci in the outer retina overlying a serous pigment epithelium detachment (PED) with focal RPE disruption on SD-OCT. SD-OCT performed 2 months before showed the same hyperreflective lesion associated with a shallower PED. No neovascular lesions were found on OCTA after six injections of bevacizumab. To conclude, careful evaluation of SD-OCT allows for early detection of type 3 neovascularization at a pre-exudative stage. OCTA may be useful in confirming the presence of intraretinal neovascular lesion and monitoring response to anti-vascular endothelial growth factor agents.
RESUMO
Resumo Objetivo: A queratite infeciosa é uma doença de incidência relativamente elevada e é responsável por um número importante de internamentos. Neste estudo pretende-se estudar diversas características epidemiológicas e clínicas associadas às queratites infeciosas de alto risco num hospital terciário em Portugal. Métodos: Realizou-se um estudo retrospetivo, onde foram incluídos todos os doentes internados por abcesso da córnea no Centro Hospitalar Universitário do Porto (CHUP), entre Abril de 2013 a Março de 2018. Caracterizou-se a população em relação aos fatores de risco, apresentação clínica, tempo de internamento, resultados de culturas, resistência antibiótica in vitro, tratamento efetuado e resultado funcional. Resultados: O estudo incluiu 105 doentes. Os principais fatores de risco foram antecedentes de cirurgia de córnea, uso de lentes de contacto e história recente de trauma ocular. 74,3% dos doentes tiveram cultura positiva com 87,9% a corresponderem a cultura bacteriana pura, sendo a Pseudomonas aeruginosa e o Streptococcus pneumoniae os agentes etiológicos mais frequentes. 27,9% das culturas positivas eram resistentes a 3 ou mais classes de antibióticos. Todos os doentes iniciaram tratamento com colírios fortificados. 29,5% dos doentes necessitaram de realizar transplante de córnea. Ao final de 6 meses de seguimento, apenas 20,9% apresentavam AV>20/40. Conclusão: Na maioria dos casos, a etiologia foi bacteriana. Observou-se um número considerável de bactérias multirresistentes. Apesar do tratamento ter permitido uma melhoria da visão na maioria dos casos, um número considerável de doentes ficou com sequelas visuais importantes.
Abstract Objective: Infectious keratitis is a pathology with a high incidence and is responsible for a large number of prolonged stay hospital admissions. The purpose was to analyze the epidemiological and clinical data associated with high risk microbial keratitis at a central hospital in Portugal. Methods: A retrospective study of all inpatients presenting with corneal abscess in Centro Hospitalar Universitário do Porto, from April 2013 to March 2018 was performed. Target population was characterized by risk factors, clinical features, length of stay, culture results, in vitro antibiotic resistance, treatment and outcome. Results: This study included 105 patients. The main risk factors were previous corneal surgery, contact lenses wear and recent history of ocular trauma. 74.3% of patients had a positive culture, 87.9% of these corresponding to a pure bacterial culture, with Pseudomonas aeruginosa and Streptococcus pneumoniae being the most common pathogens. 27.9% of positive cultures were resistant to 3 or more classes of antibiotics. All patients began treatment with fortified drops. 29.5% of patients required a corneal transplant. After 6 months of follow-up, only 20.9% presented a VA>20/40. Conclusion: Most cases were caused by bacteria. A considerable number of multi-resistant bacteria was identified. Despite most cases having improved after treatment, a large number of patients had a significant visual acuity sequelae.
