Optic neuritis and mydriasis after vaccination: a case report.

BACKGROUND: Optic neuritis (ON) is an inflammatory demyelinating condition of the optic nerve, with various causes. Its incidence is higher in children and young adults than in older adults of both genders, but is more common in women than in men. ON is rarely associated with mydriasis, and it is seldom triggered by vaccines against tetanus and diphtheria. CASE REPORT: A 36-year-old Caucasian woman presented with bilateral ON that had started 18 days after administration of a booster dose of the double adult vaccine (dT) against diphtheria and tetanus. Bilateral mydriasis persisted after treatment and clinical resolution of the ON. She experienced severe headache, blurred vision, decreased visual acuity in the right eye and bilateral mydriasis, a diagnosis confirmed by imaging tests. Treatment with oral corticosteroids resulted in rapid resolution of the neuritis; however, mydriasis persisted for several months. CONCLUSION: This study describes a very unusual case of bilateral ON associated with prolonged mydriasis after vaccination against tetanus and diphtheria that regressed after treatment with oral corticosteroids. Prolonged mydriasis was the manifestation that differed from the other cases previously described.

Belin/Ambrósio Enhanced Ectasia Display in cataract surgery and relation to final visual acuity / Belin/Ambrósio Enhanced Ectasia Display na cirurgia de catarata e sua relação com a acuidade visual final

ABSTRACT Objective To analyze and describe the coefficients found on maximum Ambrósio Relational Thickness-Maximum (ART-Max) and Belin/Ambrósio Enhanced Ectasia Display total deviation (BAD-D) in eyes with normal corneal topography subjected to cataract surgery with premium intraocular lens implantation and correlated these data with final visual acuity. Methods ART-Max and BAD-D data from 103 eyes of patients subjected to implantation of diffractive bifocal intraocular lens, with normal corneal topography who achieved visual acuity of 20/20 or 20/25 without correction after cataract surgery were analyzed. The groups with normal and abnormal values were compared using the chi-square test. Results Thirty-two (31.1%) and 71 (68.9%) eyes presented normal and abnormal ART-Max values, respectively. The difference between these groups was significant (p=0.0002). Fifty-five (53.4%) and 48 (46.6%) eyes had normal and abnormal BAD-D, respectively, and intergroup difference was not significant (p=0.9576). Conclusion Among patients with normal corneal topography who underwent premium intraocular and had good final visual acuity of 20/20 or 20/25, suspicious or abnormal indices of ART-Max and BAD-D were frequent, providing evidence that it possibly should not be a contraindication.

RESUMO Objetivo Analisar e descrever os coeficientes numéricos encontrados nos exames Ambrósio Relational Thickness-Maximum (ART-Max) e desvio total do Belin/Ambrósio Enhanced Ectasia Display (BAD-D) em olhos com topografia normal submetidos ao implante de lente intraocular premium na cirurgia de catarata, correlacionando-os com a acuidade visual final pós-operatória. Métodos Foram analisados os resultados de ART-Max e BAD-D de 103 olhos de pacientes submetidos ao implante de lentes bifocais difrativas, que apresentavam exame topográficos normal e alcançaram acuidade visual 20/20 ou 20/25 sem correção visual no pós-operatório final. Para a análise estatística entre os grupos normais e anormais ou suspeitos, utilizou-se o teste do qui-quadrado. Resultados Foram encontrados 32 (31,1%) olhos com ART-Max normal e 71 (68,9%) com ART-Max suspeito/anormal. A diferença entre os grupos foi significativa (p=0,0002). Quanto ao BAD-D, foram encontrados 55 (53,4%) olhos com resultados normais e 48 (46,6%) com resultados suspeitos/anormais. A diferença entre os grupos não foi significativa (p=0,9576). Conclusão Entre os pacientes com topografia normal submetidos ao implante de lentes premium e que alcançaram acuidade visual 20/20 ou 20/25, os índices suspeitos ou anormais de ART-Max e BAD-D eram frequentes, não se configurando em contraindicação para a realização do implante.

A Comparative Study Between the Goldmann Applanation Tonometer and the Non-Contact Air-Puff Tonometer (Huvitz HNT 7000) in Normal Eyes.

OBJECTIVE: To assess whether the non-contact air-puff tonometer (NCT) is an appropriate alternative to the Goldmann applanation tonometer (GAT) for measuring intraocular pressure (IOP). PATIENTS AND METHODS: An observational, cross-sectional, and comparative study with a quantitative approach was carried out. Two techniques for IOP measurements using the standard GAT and the NCT were compared. A total of 180 eyes from 90 patients were included in the study. RESULTS: The total mean IOP according to NCT measurements was 14.12 mmHg, and the total mean IOP according to the GAT was 12.98 mmHg; these values were significantly different (p=0.0018). When dividing the participants into three groups according to the measurement range obtained and comparing the mean NCT and GAT measurements in each group, in Group 1 (10-15 mmHg), no statistically significant difference was found between the means of the two tonometers (p=0.3100), a difference was observed between Group 2 (16-19 mmHg) and Group 3 (20 mmHg or more) (p<0.001). When dividing the participants by age group, the means obtained by the two tonometers also differed significantly between Group 4 (40-59 years) and Group 5 (60 years or more) (p<0.0001). In all groups, the mean measurements by the NCT were higher than those by the GAT. CONCLUSION: The NCT presented an approximate mean of the measures with the GAT in group 1 but was overestimated in the measurements of the groups 2 and 3.

Uncommon progression of toxoplasmic papillitis: patient perception and case report / Papilite por toxoplasmose ocular com evolução incomum: percepção do paciente e relato de caso

ABSTRACT Ocular toxoplasmosis frequently presents as necrotizing retinochoroiditis and, less often, as peripapillary chorioretinitis and/or papillitis. The progression from papillitis to peripapillary retinochoroiditis has been rarely described. We report the case of a 52-year-old patient living in southern Brazil, who developed papillitis in the right eye and was treated with systemic corticosteroids (prednisone 0.6 mg/kg/day and pulse therapy with methylprednisolone 15 mg/kg/day, for 3 days). After 14 days, the patient developed peripapillary retinochoroiditis with vitritis and decreased visual acuity (20/60), and was immediately initiated on the classic oral treatment for toxoplasmosis, consisting of pyrimethamine (50 mg/day), sulfadiazine (4 g/day), folinic acid (15 mg every 3 days) and prednisone (0.6 mg/kg/day). The visual acuity of the right eye normalized after treatment (20/20), which lasted approximately 70 days, but scotomas were detected on visual field examination, especially in the lower nasal quadrant. Although two studies mentioned this presentation, our report emphasizes the possible manifestation of ocular toxoplasmosis as papillitis in the initial phase, with progression to peripapillary retinochoroiditis and permanent visual field defects, which justifies early treatment for toxoplasmosis in suspected cases, especially in endemic regions.

RESUMO A toxoplasmose ocular manifesta-se com maior frequência por um quadro de retinocoroidite necrotizante e, com menor frequência, por coriorretinite justapapilar e/ou papilite. A evolução de papilite para retinocoroidite justapapilar raramente foi descrita. Apresenta-se o relato de caso de uma paciente de 52 anos, habitante da Região Sul do Brasil, que iniciou com quadro de papilite em olho direito, sendo tratada com corticoides sistêmicos (prednisona 0,6/mg/kg ao dia e pulsoterapia com metilprednisolona 15mg/kg ao dia, por 3 dias), mas, após 14 dias, evoluiu para retinocoroidite justapapilar, com vitreíte e diminuição de acuidade visual (20/60), sendo imediatamente instituído o tratamento via oral clássico para toxoplasmose, com pirimetamina (50 mg ao dia), sulfadiazina (4 g ao dia) e ácido folínico (15 mg a cada 3 dias), e mantida a prednisona (0.6 mg/kg/dia). A acuidade visual do olho direito normalizou após o tratamento (20/20), que durou em torno de 70 dias, porém desenvolveu escotomas ao exame de campo visual, sobretudo de quadrante nasal inferior. Embora tenham sido encontrados dois trabalhos que mencionam essa forma de apresentação, o presente relato destaca-se por enfatizar a possibilidade de manifestação da toxoplasmose ocular por meio de papilite na fase inicial, que evolui com retinocoroidite justapapilar, causando defeito permanente de campo visual, justificando que se avalie a instituição de tratamento precoce para toxoplasmose dos casos suspeitos, sobretudo em região endêmica.

Use of gabapentin in management of postoperative pain after crosslinking / Uso da gabapentina no manejo da dor pós-operatória do crosslinking

ABSTRACT Objective: The objective was to evaluate the efficacy of gabapentin in the management of neuropathic pain in patients with keratoconus, who were treated with fast (10 minutes) epi-off corneal crosslinking (CXL). Methods: This was a prospective, double-blind, randomized study. The sample comprised patients with bilateral progressive keratoconus, aged 12 years or older, who underwent a bilateral epi-off corneal CXL (fast - 10 minutes) procedure. One group was given placebo orally, and the other group received gabapentin 600 mg orally, both preoperatively. The visual analogue scale (VAS) was applied to record postoperative pain up to 48 hours after procedure. The study was conducted at the Belotto Stock Centro Oftalmológico, in the city of Joaçaba, Santa Catarina, Brazil, from June 2018 to September 2019. Results: At no point in the study significant differences were observed between groups, in terms of pain intensity measured by means of the VAS questionnaire, or of opioid use (Paco®), though opioid consumption was 21% lower in the group receiving gabapentin. Conclusion: We concluded gabapentin has no efficacy in postoperative pain control after epi-off corneal CXL (fast - 10 minutes). Although there was no statistically significant difference, the group that received gabapentin suffered less pain, resulting in lower opioid consumption. UTN number: U1111-1256-0330.

RESUMO Objetivo: Avaliar a eficácia do uso da gabapentina no manejo da dor neuropática em pacientes portadores de ceratocone submetidos ao tratamento de crosslinking corneano epi-off fast de 10 minutos. Métodos: Tratou-se de pesquisa prospectiva, duplo-cega, randomizada. A amostra foi composta de pacientes com ceratocone progressivo bilateral, a partir dos 12 anos de idade, submetidos ao procedimento de crosslinking corneano acelerado epi-off fast de 10 minutos bilateral. Um grupo recebeu placebo via oral e o outro, gabapentina 600mg, via oral, ambos no pré-operatório. A Escala Visual Analógica foi aplicada para registrar a dor pós-operatória até 48 horas após o procedimento. A pesquisa foi realizada no período de junho de 2018 a setembro de 2019 em um centro oftalmológico. Resultados: Não foram observadas diferenças estatísticas significativas para ambos os grupos, tanto na intensidade da dor medida pela Escala Visual Analógica, como na redução do uso do opioide (Paco®), em qualquer horário analisado durante um período de 48 horas. No entanto, houve redução de 21% no consumo de opioides pelo grupo que fez uso da gabapentina. Conclusão: A gabapentina não demonstrou eficácia no controle da dor no pós-operatório do crosslinking corneano epi-off fast de 10 minutos. No entanto, observou-se que, mesmo não havendo diferença estatisticamente significativa, houve diminuição da dor no grupo em que foi usada a gabapentina, resultando na redução do consumo de opioides. Número UTN: U1111-1256-0330.

Efficacy of Standard and Accelerated (10 Minutes) Corneal Crosslinking in Keratoconus Stabilization.

PURPOSE: To evaluate whether Accelerated CXL for 10 minutes is as effective as standard CXL for 30 minutes for the treatment of progressive keratoconus. PATIENTS AND METHODS: Eighty-two eyes of 62 patients with keratometry examinations performed before and 6 months after surgery were studied. A total of 39 eyes underwent standard CXL with UVA irradiation of 3 mW/cm2 for 30 minutes and 32 eyes underwent Accelerated CXL UVA irradiation of 9 mW/cm2 for 10 minutes. The eyes of all patients had corneal thicknesses of at least 450 microns (400 microns after epithelium removal). RESULTS: The means of the keratometry measurements in the preoperative period for the eyes subjected to standard CXL were 46.27 dioptres (D) on the flat axis (K1) and 48.93 D on the steep axis (K2). Postoperatively, K1 was 46.21 D and K2 was 48.97 D, a difference without statistical significance (p = 0.47 and p = 0.48, respectively). In the Accelerated CXL protocol, the preoperative measurements were 44.55 D and 46.19 D for K1 and K2, respectively. In the postoperative period, K1 was 43.37 D, and K2 was 46.64 D (p = 0.38 and p = 0.27, respectively). In the standard group, the mean maximum keratometry (Kmax) preoperatively was 55.87 D, with no statistical significance (p = 0.29). In the preoperative period, the Kmax of the Accelerated group was 51.15 D, with no statistical significance (p = 0.32). CONCLUSION: Based on the keratometry results, the accelerated protocol was as effective as the standard protocol for keratoconus stabilization.

Surgical debridement of corneal shield ulcers in pediatric patients: two case reports and a review of the literature.

BACKGROUND: Ocular allergy is a common disease, especially in the pediatric population, with unpleasant and long-term consequences, including corneal complications and decreased visual acuity. This study reports two cases of corneal shield ulcer due to vernal keratoconjunctivitis, with good results of surgical debridement performed after failure of long-term clinical treatment. Furthermore, this study highlights that this therapeutic approach, although less common, is efficient in treating refractory cases that cause suffering in pediatric patients. CASE PRESENTATION: The first patient was a 7-year-old Caucasian boy with chronic ocular allergy, especially photophobia, who had been treated with eye drops, antihistamine, and corticosteroids for 60 days without success. Biomicroscopy of the right eye showed the presence of gelatinous limbus, giant papillae in the tarsal conjunctiva, and a shield ulcer measuring 6.0 mm vertically and 2.7 mm horizontally. Surgical debridement was performed, and the ulcer did not recur. The second patient was a 4-year-old Caucasian boy with chronic ocular allergy, especially itching and photophobia, who had been treated with eye drops for 1 year without success. Biomicroscopy of the left eye showed a shield ulcer, with a dense central corneal plaque, measuring 8 mm vertically and 3.5 mm horizontally. Surgical debridement of the ulcer was performed immediately because of the chronicity of the case and severity of the lesion, and the treatment was effective. CONCLUSIONS: The treatment of shield ulcers caused by vernal keratoconjunctivitis in the two reported cases was curative and definitive by surgical debridement in the 7-month follow-up period. Therefore, the early debridement of shield ulcers refractory to drug treatment can considerably reduce the time of disease evolution and the probability of ocular complications caused by clinical treatment or disease chronicity. However, this approach is rarely described in the literature and needs to be included in the ophthalmologist's therapeutic arsenal.

Atendimento às urgências oftalmológicas em unidade de pronto atendimento / Assistance to ophthalmic urgencies in emergency care unit

Objetivo: Descrever os atendimentos oftalmológicos realizados em uma unidade geral de pronto atendimento. Métodos: Estudo prospectivo, observacional e descritivo cuja coleta de dados foi realizada em prontuários de pacientes atendidos na unidade por queixas oftalmológicas no período entre julho e novembro de 2018. Resultados: Foram revisados 445 prontuários de pacientes oftalmológicos, representando 2,18% do número total de pacientes atendidos no período. Foram encontrados 182 (40,89%) pacientes com diagnóstico de conjuntivite, 139 (31,23%) de trauma ocular e 78 (17,52%) com outros diagnósticos. Dentre os pacientes com trauma ocular, 115 (82,73%) eram do sexo masculino e 42 resultaram de acidente de trabalho. Conclusões: Conclui-se que a maioria dos pacientes oftalmológicos foi atendida com diagnóstico de conjuntivite ou trauma ocular e parte desses não faziam uso de EPI no momento da ocorrência. Os resultados permitem inferir que os médicos plantonistas precisam ter noções sobre as doenças oftalmológicas prevalentes na unidade de pronto atendimento e que desponta a necessidade de se promover campanhas para a prevenção de acidentes de trabalho junto às empresas da região, acompanhadas de fiscalização, para reduzir o acometimento de pacientes com trauma ocular resultante da não observância das normas de proteção.

Objective: To describe the ophthalmologic services performed in a general emergency care unit. Methods: Prospective, observational and descriptive study whose data collection was performed on medical records of patients seen at the unit for eye complaints in the period between July and November 2018. Results: 445 medical records of ophthalmological patients were reviewed, representing 2,18% of the number total number of patients seen in the period. 182 (40.89%) patients were diagnosed with conjunctivitis, 139 (31.23%) with ocular trauma and 78 (17.52%) with other diagnoses. Among the patients with ocular trauma, 115 (82.73%) were male and 42 resulted from an occupational accident. Conclusions: Most ophthalmologic patients were treated with a diagnosis of conjunctivitis or ocular trauma and part of them did not use PPE at the moment of the accident. The results allow us to infer that physicians on duty need to have knowledge about the ophthalmological diseases prevalent in the emergency care unit and that there is a need to promote campaigns for the prevention of work accidents with companies in the region, accompanied by inspection, reducing the involvement of patients with eye trauma who were not obeying the rules of protection.

Phacoemulsification: an alternative for prophylaxis of a glaucomatous crisis.

PURPOSE: To evaluate the effectiveness of phacoemulsification for the prophylaxis of a glaucomatous crisis in the affected and contralateral eyes; to investigate the evolution of intraocular pressure levels after iridotomy and phacoemulsification; to assess the need for antiglaucoma medication after the proposed treatments; and to identify potential complications associated with phacoemulsification. PATIENTS AND METHODS: This retrospective observational study evaluated 22 eyes of 12 patients between September 2006 and September 2018, with a minimum follow-up period of 9 months. RESULTS: After iridotomy, a persistent increase in intraocular pressure was observed in 42.85% of the cases, 100% of the patients required antiglaucoma medications, and recurrence of angle closure was observed in 28.57% of the cases. In contrast, during follow-up of phacoemulsification, the intraocular pressure levels in all eyes evaluated remained normal, without the need for medication, and no recurrence of the glaucomatous crisis or other complications was observed. CONCLUSION: Phacoemulsification maybe consequently more effective than laser iridotomy for the resolution of angle-closure glaucoma and particularly for preventing its relapses.

Comparison of macular thickness by optical coherence tomography measurements after uneventful phacoemulsification using ketorolac tromethamine, nepafenac, vs a control group, preoperatively and postoperatively.

PURPOSE: To analyze, using optical coherence tomography, the macular thickness values of patient groups using nonsteroidal anti-inflammatory drug (NSAID) eye drops or artificial tears during uncomplicated cataract surgery. METHODS: A total of 77 eyes from 42 patients were analyzed. The patients were divided into three groups, each using one of the following ophthalmic sterile suspensions: nepafenac (21 eyes), propylene glycol (24 eyes), or ketorolac tromethamine (32 eyes). RESULTS: The mean macular thicknesses of the nepafenac group, preoperatively as well as at 1, 7, and 45 days postoperatively, were 216.42, 216.61, 222.47, and 218.28, respectively; those of the propylene glycol control group were 218.29, 214.50, 219.37, and 228.45, respectively; and those of the ketorolac tromethamine group were 217.46, 220.71, 225.25, and 228.46, respectively. There were no significant differences between groups at any time, with p-values of 0.971, 0.6742, 0.6711, and 0.327, respectively. CONCLUSION: During the study period, no significant differences in macular thickness were observed between the patient groups using two types of NSAIDs or between those groups and the control group that used propylene glycol, indicating that neither drug was superior to the other or the placebo. However, a slight macular thickening, without reduction of visual acuity, was observed in all groups.

Subjective evaluation of uncorrected vision in patients undergoing cataract surgery with (diffractive) multifocal lenses and monovision.

PURPOSE: To analyze patient satisfaction and difficulties with bilateral multifocal intraocular lenses (IOLs) implantation and aspheric monofocal IOLs implantation using monovision, after cataract surgery. MATERIALS AND METHODS: A total of 61 participants were included in the study, 29 with monovision and 32 with multifocal lenses. The inclusion criteria were patients undergoing phacoemulsification for bilateral visual impairment due to cataracts and presenting with postoperative visual acuity of 20/30 or better for distance and line J3 or better for near vision. RESULTS: The 2 groups had similar results regarding difficulties with daily activities such as distance vision, near vision, watching television, reading, cooking, using a computer or cellphone, shaving/putting on makeup and shopping. There were differences in responses between the groups regarding difficulty with night vision (P=0.0565) and night driving (P=0.0291). Degree of satisfaction in terms of distance vision without glasses was statistically significantly better in monovision group (P=0.0332), but not for near (P=0.9101). CONCLUSION: Both techniques yielded satisfactory results regarding visual acuity for different activities without the need to use glasses. Multifocal lenses are a good option for patients with the exception of night driving, and who desire independence from glasses.

Ergophthalmology in accounting offices: the computer vision syndrome (CVS) / Ergoftalmologia em escritórios de contabilidade: a síndrome visual do computador (SVC)

Abstract Purpose: This study aimed to determine the presence of the symptoms of computer vision syndrome (CVS) accounting office employees. Methods: The research tools used were a questionnaire based on the set of symptoms of CVS rated by Likert scale (1-5) and workplace observations based on Ergonomic Workplace Analysis (EWA). Results: The participants who worked with a viewing angle of less than 10º relative to the screen had more symptoms, particularly of pain in the back of the neck and back (p = 0.0460). The participants who used lighting other than 450 and 699 lux reported significant headache (p = 0.0045) and dry eye (p = 0.0329) symptoms. Younger workers had more headaches (p = 0.0182), and workers with fewer years of employment had more headaches and dry eyes symptoms (p = 0.0164 and p = 0.0479, respectively). A total of 37% of the participants reported a lack of guidance regarding prevention and painful symptoms in the back of the neck and back (p = 0.0936). Conclusion: Younger participants with fewer years of employment, who had not received information regarding proper computer use, who did not use lighting between 450 and 699 lux or who worked with viewing angles of less than 10º had more computer vision syndrome symptoms.

Resumo Objetivo: Este trabalho objetivou averiguar a presença dos sintomas da Síndrome Visual dos Computadores (SVC) trabalhadores de escritórios de contabilidade. Métodos: Como instrumentos de pesquisa utilizou-se um questionário baseado no conjunto de sintomas da SVC, avaliado por Escala Likert (1-5), e foram realizadas observações no local de trabalho baseadas na Avaliação Ergonômica de Postos de Trabalho. Resultados: Os participantes que trabalhavam com o ângulo de visão menor do que 10º em relação à tela foram os que apresentaram mais sintomas sobretudo de dor na parte posterior do pescoço e nas costas (p=0,0460). Aqueles que usavam iluminação diferente de 450 e 699 lux reportaram sintomas significativos para dor de cabeça (p=0,0045) e ressecamento ocular (p=0,0329). Os mais jovens apresentaram mais dor de cabeça (p=0,0182) e aqueles com menor tempo de trabalho mais sintomas de dor de cabeça e ressecamento ocular (respectivamente p=0,0164 e p=0,0479). A falta de recebimento de orientações sobre prevenção foi confirmada por 37% participantes que referiram mais sintomas de dor na parte posterior do pescoço e nas costas (p=0,0936). Conclusão: Os participantes mais jovens, com menor tempo de trabalho, que não haviam recebido informações sobre o uso de computador, não utilizavam iluminação entre 450 e 699 lux ou trabalhavam com o ângulo de visão menor do que 10º apresentaram mais sintomas da síndrome visual do computador.

Acute corneal hydrops during pregnancy with spontaneous resolution after corneal cross-linking for keratoconus: a case report.

BACKGROUND: Keratoconus may progress to acute corneal hydrops even after cross-linking. In some cases, keratoconus progresses during pregnancy. In this report, we present a case of a patient with increased anterior stromal resistance after cross-linking that would favor nonprogression of keratoconus during pregnancy. CASE PRESENTATION: We report that cross-linking is likely to have had a protective effect in a white pregnant patient with acute corneal hydrops who showed rapid improvement, as documented by corneal topography. Improvement occurred within 8 days, whereas up to 250 days are reported in the literature. No keratoconus progression occurred in the 20-month follow-up period. CONCLUSIONS: Cross-linking failed to prevent the occurrence of acute corneal hydrops after rupture of Descemet's membrane but most likely helped to accelerate the resolution of the condition. Corneal hardening resulting from cross-linking may have also contributed to stabilizing keratoconus during pregnancy.

Infectious crystalline keratopathy caused by Cladosporium sp. after penetrating keratoplasty: a case report.

BACKGROUND: Infectious crystalline keratopathy is a rare, progressive infection characterized by the insidious progression of branches and crystalline corneal opacities with minimal or no inflammation. This case report describes the evolution of an infectious crystalline keratopathy caused by Cladosporium sp., which developed after tectonic keratoplasty in a patient with a history of ocular trauma. CASE PRESENTATION: A 40-year-old Brazilian male was the victim of firework-induced trauma to the left eye, which resulted in a corneal laceration that could not be sutured as well as a severe traumatic cataract. The patient underwent penetrating keratoplasty and phacoemulsification. During postoperative follow-up, another therapeutic keratoplasty was required because unresponsive infectious keratitis was observed. The infiltrate's characteristics were suggestive of infectious crystalline keratopathy; in particular, the infiltrate was insidious and progressive, and grayish-white branches appeared in the anterior corneal stroma. As different therapies were administered, inflammatory reactions ranging from mild to severe were observed. The infection was unresponsive to typical antifungal drugs. This lack of response most likely occurred due to steroid treatment and the diffuse corneal spread of an atypical microorganism, which was subsequently identified in culture as Cladosporium sp. After the second therapeutic keratoplasty, the patient's eye integrity was successfully reestablished. CONCLUSION: This study likely provides the first report describing a case of infectious crystalline keratopathy caused by Cladosporium sp. This case emphasizes the clinical characteristics and outcome of this type of keratitis.

Sealing the gap between conjunctiva and Tenon's capsule in primary pterygium surgery / Adição do selamento entre conjuntiva e cápsula de Tenon em cirurgia de pterígio primário

Objetive: To assess the results of an alternative surgical approach in the excision of primary pterygium by analyzing the rates of recurrence and of intraoperative and postoperative complications. Methods: Retrospective cross-sectional study based reviewing the clinical records of individuals subjected to surgery for pterygium, with conjunctival autograft transplantation, fibrin glue and intraoperative application of mitomycin C. In addition, sealing was performed by suturing the gap between the conjunctiva and Tenon’s capsule. A total of 36 eyes from 35 individuals were subjected to the assessed techniques. The study variables were complications of surgery and recurrence rates during a minimun follow-up period of 6 months. Results: No recurrence occurred during the follow-up period. One graft (2.8%) exhibited partial retraction, but pterygium did not recur. The intraocular pressure increased in one eye (2.8%) and was controlled by clinical methods. Conclusion: Eyes in which a barrier was established between the conjunctiva and Tenon’s capsule by sealing the gap between them showed an absence of recurrence in the sample studied. However, there is the need of a random prospective study with a control group for a more accurate conclusion on the efficacy of the technique .

Objetivo: Avaliar os resultados de uma abordagem cirúrgica alternativa na excisão de pterígio primário por meio da observação das taxas de recidiva e de complicações intraoperatórias e pós-operatórias Métodos: Estudo retrospectivo e transversal realizado a partir da revisão de prontuários de pacientes submetidos à cirurgia de pterígio com transplante autólogo de conjuntiva, cola de fibrina e aplicação intraoperatória de mitomicina C. Além disso, foi realizado através de sutura, o selamento da lacuna entre a conjuntiva e cápsula de Tenon. No total, 36 olhos de 35 pacientes foram submetidos à técnica. As variáveis do estudo foram complicações da cirurgia e taxas de recidiva durante um período mínimo de 6 meses de seguimento. Resultados: Não foram constatadas recidivas durante o tempo de seguimento. Um enxerto (2,8%) desenvolveu retração parcial, sem posterior recorrência do pterígio, e um olho (2,8%) apresentou aumento da pressão intraocular, que foi controlada clinicamente. Conclusão: A criação de uma barreira entre a conjuntiva e cápsula de Tenon, por meio do selamento da lacuna, mostrou ausência de recidiva na amostra estudada. Necessita-se, no entanto, de um estudo prospectivo randomizado com grupo controle para uma conclusão mais precisa da eficácia da técnica. .

Indicações de ceratoplastia: estudo retrospectivo em um Hospital Universitário / Indications of keratoplasty: a retrospective study in a University Hospital

OBJETIVO: Descrever o perfil demográfico-epidemiológico e as indicações de ceratoplastia no Hospital Universitário Santa Terezinha de Joaçaba/SC no período de outubro de 2006 a abril de 2011. MÉTODOS: Os prontuários foram examinados no Centro Oftalmológico Belloto Stock de Joaçaba (SC) e os pacientes foram acompanhados antes e depois da ceratoplastia. Os dados analisados foram cidade de origem, idade, gênero, etnia e indicação da ceratoplastia. RESULTADOS: Foram analisados os prontuários de 85 pacientes em que foram realizadas 100 ceratoplastias. Quanto à origem, 79% dos pacientes provinham da região do Meio-Oeste e os demais de outras regiões de Santa Catarina. A média de idade foi de 38 ± 17,61 anos, variando de 13 a 87. Quanto ao gênero encontrou-se prevalência do sexo masculino em 57,6%. A etnia branca foi declarada por 94,1% dos pacientes e a parda por 5,9%. As indicações de ceratoplastia foram ceratocone em 51 (51%) olhos, retransplante em 15 (15%), todos pacientes provenientes de outros serviços, leucoma pós-herpes em 13 (13%), ceratopatia bolhosa pós-facectomia em 6 (6%), distrofia corneana em 5 (5%), leucoma pós-trauma perfurante em 4 (4%), úlcera bacteriana sem resposta ao tratamento clínico em 3 (3%) e outras causas em 3 (3%). Das 100 ceratoplastias realizadas 98 (98%) foram penetrantes e 2 (2%) lamelares anteriores profundas. CONCLUSÃO: O estudo concluiu que o perfil dos pacientes submetidos à ceratoplastia caracterizou-se como jovem, de etnia branca, com predominância do sexo masculino e as quatro principais indicações de ceratoplastia foram ceratocone, retransplante, leucoma pós-herpes e ceratopatia bolhosa pós-facectomia.

OBJECTIVE: To describe the demographic-epidemiological profile and indications of keratoplasty at the University Hospital Santa Terezinha of Joaçaba (SC) from october 2006 to april 2011. METHODS: The records were obtained from the files of the Eye Center Belloto Stock of Joaçaba (SC), where the patients were accompanied before and after keratoplasty. The data analyzed were city of origin, age, gender, ethnicity and indication of keratoplasty. RESULTS: The medical records of 85 patients were analyzed, who underwent 100 keratoplasties. As to the origin, 79% of patients were in the region of the Midwest and the rest from other regions of Santa Catarina. The average age of patients was 38 ± 17.61 years, ranging from 13 to 87 years. As the gender, male prevalence was 57.6%. The white race was declared by 94.1% of patients and 5.9% for mixed. The indications for keratoplasty were keratoconus in 51 (51%) eyes, regraft in 15 (15%), leucoma post-herpes in 13 (13%), bullous keratopathy after cataract surgery in 6 (6%), corneal dystrophy in 5 (5%), leucoma after penetrating trauma in 4 (4%), bacterial ulcer unresponsive to medical treatment in 3 (3%) and other causes in 3 (3%). Of the 100 keratoplasties performed, 98 (98%) were penetrating and 2 (2%) lamellar. CONCLUSION: The study concluded that the profile of patients undergoing keratoplasty was characterized as a population of young caucasians, with a slight male predominance, and the four most common indications for keratoplasty were keratoconus, regraft, post-herpes leucoma and bullous keratopathy after cataract extraction.

Solar retinopathy without abnormal exposure: case report.

Solar retinopathy is photochemical damage to the retina, usually caused, by direct or indirect solar observation resulting from the use of hallucinogenic drugs, mental disorders or during eclipses. There may be a loss of visual acuity. We report the case of a 38-year-old patient who presented with a clinical diagnosis of solar retinopathy in the left eye, no prior history of sun exposure, normal visual acuity and complaints of metamorphopsia. Optical coherence tomography showed a rupture of the retinal pigment epithelium, confirming class II solar retinopathy. Visual acuity tends to normalize after 3 to 9 months, but not always. Thus, there is a real need to educate people about using eye protection during sun exposure especially given that some people may be highly susceptible to retinal damage, which was presumably the case for this patient. Finally, we note the importance of optical coherence tomography in diagnosing solar retinopathy.

Idiopathic dilated episcleral vessels (Radius-Maumenee syndrome): case report.

Radius-Maumenee syndrome comprises idiopathic dilated episcleral vessels that are usually associated with glaucoma. The case described herein is of a male patient, 69 years old, with chronic dilation of the episcleral vessels and glaucoma in his left eye, with no history of systemic disease. Visual acuity and fundoscopy were normal in both eyes. Tonometry measured 14 mmHg in the right eye and 25 mmHg in the left. Computed tomography angiography (CTA) was negative for carotid-cavernous fistula. The intraocular pressure of the left eye decreased to 20 mmHg with clinical treatment without regression of episcleral venous dilation. Trabeculectomy normalized the intraocular pressure and reduced the vessels. There was choroidal effusion on day 16 of the postoperative period, which resolved with corticosteroids. Although choroidal effusion can occur, the efficacy of trabeculectomy in controlling glaucoma and the reduction of episcleral vessels are clearly demonstrated.

Retinopatia solar é o dano fotoquímico à retina causado, geralmente, pela observação solar, direta ou indireta, devido ao uso de drogas alucinógenas, distúrbios psíquicos ou durante eclipses. Pode haver, ou não, perda de acuidade visual. Relata-se o caso de uma paciente, 38 anos, com quadro de retinopatia solar em olho esquerdo, sem história prévia de exposição solar, apresentando acuidade visual normal e queixa de metamorfopsia. A tomografia de coerência óptica mostrou ruptura do epitélio pigmentar da retina, confirmando retinopatia solar padrão II. A acuidade visual tende a normalizar-se entre 3 a 9 meses, mas nem sempre. Assim, enfatiza-se a necessidade de orientação à população sobre proteção ocular durante exposição solar pela possibilidade de existirem pessoas com susceptibilidade elevada ao dano retiniano, como se presume possa ter ocorrido com esta paciente. Finalmente, destaca-se a importância da tomografia de coerência óptica para o diagnóstico da retinopatia solar.
