ABSTRACT Purpose: The aim of the present study was to measure the free carnitine and acylcarnitine levels in pterygium tissue and normal conjunctival tissue at the metabolomics level using tandem mass spectrometry. Methods: In this prospective, clinical randomized study, pterygium tissues and normal conjunctival tissues taken during pterygium excision with autograft were compared regarding their free carnitine and acylcarnitine profiles. After tissue homogenization, carnitine levels were measured using tandem mass spectrometry. The data were statistically analyzed with the Wilcoxon signed-rank test. Results: Pterygium and normal conjunctival tissue samples from a single eye of 29 patients (16 females, 13 males; mean age, 54.75 ± 11.25 years [range, 21-78 years]) were evaluated. While the free carnitine (C0) level was significantly high in the pterygium tissue (p<0.001), acylcarnitine levels were significantly high in some esterized derivatives (C2, C5, C5:1, C5DC, C16:1, C18, methylglutarylcarnitine) (p<0.05). No statistically significant difference was determined for the other esterized derivatives (p>0.05). Conclusion: That the carnitine levels in pterygium tissue were higher suggests that acceleration of cell metabolism developed secondary to chronic inflammation and the premalignant characteristics of pterygium tissue. High carnitine levels may also effectively suppress the apoptosis process. The data reported in our study indicate that further, more extensive studies of the carnitine profile could help clarify the pathogenesis of pterygium.
RESUMO Objetivo: O objetivo deste estudo foi medir os níveis de carnitina livre e acil-carnitina a nível metabolómico com espectrometria de massa em tandem no tecido do pterígio e no tecido conjuntivo normal. Método: Neste estudo prospetivo, clínico e aleatório, os tecidos de pterígio e os tecidos normais de conjuntiva, retirados durante a cirurgia de pterígio com autoenxerto, foram comparados em relação ao perfil de carnitina livre e de acil-carnitina. Após a homogeneização dos tecidos, os níveis de carnitina foram medidos por espectrometria de massa em tandem. A análise estatística dos dados foi realizada com o teste dos postos sinalizados de Wilcoxon. Resultados: A avaliação foi feita através de amostras de tecido pterígio e de conjuntiva normal de um único olho de 29 pacientes (16 mulheres, 13 homens). A média de idade dos pacientes foi de 54,75 ± 11,25 anos (faixa dos 21 aos 78 anos). Enquanto o nível de carnitina livre (C0) foi significativamente elevado no tecido pterígio (p<0,001), os níveis de acil-carnitina foram significativamente elevados em alguns derivados esterificados (C2, C5, C5: 1, C5DC, C16:1, C18, metilglutaril carnitina) (p<0,05). Não foi determinada uma diferença estatisticamen te significante noutros derivados esterificados (p>0,05). Conclusão: Os níveis mais elevados de carnitina no tecido do pterígio sugerem que a aceleração do metabolismo celular se tenha tornado secundária com o efeito da inflamação crónica e o caráter pré-maligno do tecido do pterígio. Os níveis elevados de carnitina também podem ser eficazes na supressão do processo de apoptose. Os dados obtidos no estudo indicam que estudos mais extensivos do perfil da carnitina contribuiriam para o esclarecimento da patogénese do pterígio.

ABSTRACT Here, we present a case in which extensive bulbar conjunctival Kaposi's sarcoma was the initial presentation of human immunodeficiency virus in a 36-year-old man. The patient had a 3-month history of recurrent self-limited inferior conjunctiva hyperemia in the right eye, and presented with a painless bullous lesion in the right inferior bulbar conjunctiva persisting for 15 days. Surgical incision biopsy was performed at five locations and revealed a pattern compatible with Kaposi's sarcoma. Serologic testing was positive for human immunodeficiency virus; however, the patient had no other symptoms, or knowledge of human immunodeficiency virus infection. This case highlights the need to consider Kaposi's sarcoma as an early presentation of human immunodeficiency virus even if the patient denies infection.
RESUMO Este relato de caso apresenta um sarcoma de Kaposi extenso na conjuntival bulbar como a apresentação inicial do vírus da imunodeficiência humana em um homem de 36 anos de idade. O paciente tinha história de hiperemia na conjuntiva inferior do olho direito há 3 meses, autolimitada e recorrente e de surgimento de uma lesão bolhosa indolor no mesmo local 15 dias antes da sua apresentação. Uma biópsia incisional cirúrgica foi realizada e revelou um padrão compatível com sarcoma de Kaposi. Teste sorológico posterior revelou positividade para o vírus da imunodeficiência humana, no entanto, o paciente não apresentou outros sintomas, sinais ou conhecimento prévio sobre a infecção. Como conclusão deste caso, deve se ressaltar que a suspeita do diagnóstico do sarcoma de Kaposi deve ser levantada ainda que na apresentação inicial do vírus da imunodeficiência humana ou mesmo naqueles ainda sem este diagnóstico.

ABSTRACT Purpose: We evaluated the role of the conjunctival flap rotation technique using 5-fluorouracil and adjuvant therapy with topical cyclosporine A at 0.05% during short pre- and postoperative periods for the prevention of primary pterygium recurrence. Methods: In this prospective study, 76 patients with primary pterygium (76 eyes) were categorized into two groups: the control group with 31 patients who did not receive cyclosporine treatment, and the cyclosporine group with 45 patients who received topical cyclosporine A (0.05%) twice a day, for 10 days before and 10 days after the pterygium excision operations. Patients were examined for disease recurrence, side effects, and complications at 10 and 21 days, and at 2 and 6 months after the operation. Data on demography, systemic diseases, and ophthalmologic histories were obtained from all patients, and these data were analyzed using descriptive statistics involving the absolute and relative percentages of frequency distribution. Goodman test was used for contrasts among multinomial populations to study the association between cyclosporine A and recurrence. Results: Most patients were between 30 and 60 years of age, and 67.1% were women. We confirmed a higher recurrence in patients with occupational sunlight exposure. The cyclosporine A used topically 10 days before and 10 days after the pterygium removal did not significantly reduce the recurrence of the pterygium. Conclusion: Topical 0.05% cyclosporine A when used for 10 days before and 10 days after the pterygium removal does not prevent or reduce the recurrence of primary pterygium.
RESUMO Objetivo: Avaliamos os resultados da técnica de rotação de retalho conjuntival com uso de 5-fluorouracil e terapia adjuvante com ciclosporina A tópica a 0,05%, usada no pré e pós-operatório por curto período, quanto à prevenção da recidiva do pterígio primário Métodos: Estudo prospectivo, com 76 pacientes portadores de pterígio primário (76 olhos), divididos em dois grupos: controle com 31 pacientes que não receberam tratamento com ciclosporina e grupo ciclosporina com 45 pacientes que receberam ciclosporina tópica A (0,05%) duas vezes ao dia, por 10 dias antes e 10 dias após a cirurgia de excisão do pterígio. Os pacientes foram avaliados quanto à recorrência, efeitos colaterais e complicações com 10, 21 dias, 2 e 6 meses de pós-operatório. Dados demográficos, doenças sistêmicas e histórico oftalmológico foram coletados de todos os pacientes e esses dados foram analisados por meio de estatística descritiva envolvendo o percentual absoluto e relativo de distribuição de frequência. O teste de Goodman para contrastes entre populações multinomiais foi utilizado para o estudo da associação entre a ciclosporina A e a recorrência Resultados: A maioria dos pacientes tinha entre 30 e 60 anos e 67,1% eram mulheres. Confirmamos uma maior recorrência em pacientes com exposição ocupacional ao sol. A ciclosporina A tópica utilizada 10 dias antes e 10 dias após a remoção do pterígio não reduziu significativamente a sua recorrência Conclusão: A ciclosporina A tópica a 0,05% quando utilizada por 10 dias no pré e 10 dias no pós-operatório, não previne ou reduz a recidiva do pterígio primário significativamente.

Introdução: A reconstrução de pálpebra inferior representa um desafio peculiar ao cirurgião plástico, uma vez que traduz uma região facial de importância estética e funcional. O objetivo é apresentar uma técnica opcional para a reconstrução de defeitos da pálpebra inferior com o retalho cutâneo zigomáticopalpebral. Esta técnica mostra uma alternativa nos casos de pele escleroatrófica de pessoas idosas, bem como para pessoas jovens, que não apresentam redundância da pele palpebral superior, impossibilitando por exemplo o uso de enxertos de pálpebra superior ou retalhos como o de Fricke ou Tripier. Métodos: Os autores mostram a indicação do retalho em casos de ectrópio cicatricial, reconstrução após ressecção de neoplasias, associação com outros retalhos como de Hughes ou para cobertura de enxertos cartilaginosos. É um retalho de transposição composto por pele e subcutâneo, randomizado. A técnica baseia-se no uso de retalho local, de características muito semelhantes à área do defeito, o que permite mimetização, segurança e exequibilidade. Resultados: Os resultados imediatos e tardios são satisfatórios e bem aceitos pelos pacientes e pela equipe cirúrgica em termos estéticos e funcionais, com oclusão palpebral adequada e lubrificação ocular preservada. Conclusão: O retalho zigomático-palpebral apresenta como vantagens a simplicidade de execução, sangramento mínimo, baixa morbidade de área doadora e feito sob anestesia local. O objetivo de reconstruir defeitos da pálpebra é restaurar a anatomia e função. Esta pode ser uma tarefa desafiadora, especialmente em defeitos maiores que podem estar presentes nos procedimentos oncológicos em jovens e em idosos com pele escleroatrófica e mínima frouxidão.
Introduction: Lower eyelid reconstruction represents a unique challenge to plastic surgeons, since it involves a facial region of aesthetic and functional importance. The objective is to present an optional technique for the reconstruction of lower eyelid defects using zygomatic-palpebral skin flap. This technique represents an alternative in cases of scleroatrophic skin in older patients, and for young people who do not have an upper eyelid skin redundancy, which prevents, for example, the use of upper eyelid grafts or flaps such as those of Fricke or Tripier. Methods: The authors describe the flap used in cases of cicatricial ectropion and reconstruction after resection of neoplasms and association with other flaps, such as those of Hughes, or for coverage of cartilage grafts. The flap consisted of a transposition flap made up of skin and underlying subcutaneous tissues, randomized . The technique was based on the use of a local flap with highly similar characteristics to the defect area, which allowed it to mimic functions, while being safe and feasible. Results: The immediate and late results in terms of aesthetics and function were satisfactory and well accepted by patients and the surgical team, with adequate eyelid occlusion and preserved ocular lubrication. Conclusion: The advantages of the zygomatic-palpebral flap are its ease of execution, minimal bleeding, low morbidity of the donor area, and the use of local anesthesia. The reconstruction of eyelid defects aims to restore anatomy and function. This can be a challenging task, especially in cases with larger defects that may be present after oncologic procedures both in young and old patients presenting with scleroatrophic skin and minimal tissue laxity.

ABSTRACT We report the case of a patient who received conjunctival tattooing for cosmetic purposes with associated complications. A 28-year-old male experienced severe ocular pain after undergoing conjunctival tattooing. Slit-lamp examination revealed blue deposits over the conjunctiva in association with intense conjunctival edema and a 4+ anterior chamber cellular reaction. The patient underwent clinical treatments to control ocular inflammation. Two months after the injury, the patient was still in follow-up to ensure that any further complications were managed and documented. This unusual case of conjunctival tattooing resulted in conjunctival edema and anterior uveitis. Because of the increasing popularity of eyeball tattooing, the potentially severe complications of this procedure may become more common.
RESUMO Relatamos um caso de um paciente que realizou tatuagem conjuntival para fins cosméticos com complicações associadas. Um homem de 28 anos de idade apresentou dor ocular importante após tatuagem conjuntival. O exame da lâmpada de fenda revelou depósitos azuis sobre a conjuntiva, associados a um intenso edema conjuntival e uma reação de câmara anterior de 4+ de células. O paciente foi submetido a tratamentos clínicos para controlar a inflamação ocular. Dois meses após o ocorrido, o paciente ainda estava em acompanhamento para garantir que quaisquer outras complicações fossem gerenciadas e documentadas. Um caso incomum de tatuagem conjuntival resultou em edema conjuntival e uveíte anterior. Devido à crescente popularidade da tatuagem no globo ocular, complicações potencialmente graves deste procedimento podem se tornar mais comuns.

Resumo Pterígios são lesões geralmente benignas que na maioria dos casos não requer tratamento específico. É um crescimento fibrovascular sobre a córnea, geralmente a partir do lado nasal. Sua causa ainda não foi elucidada, mas parece estar relacionada à exposição aos raios ultravioleta. Quando os sintomas não são controlados com tratamento conservador, a cirurgia é indicada, porém o índice de recidiva ainda é alto, e os esforços têm sido no sentido de reduzir esse índice. A mitomicina C (MMC) é uma opção de adjuvante à cirurgia por ser um inibidor da proliferação de fibroblastos, diminuindo o risco de recorrência do pterígio. Relatamos aqui um caso que descreve cirurgia de pterígio realizada em ambos os olhos de uma mesma paciente, sendo um com MMC e outro sem ela. Os resultados e o índice de proliferação celular dos dois olhos foram comparados entre si.
Abstract Pterygia are usually benign lesions that do not require specific treatment. It is a fibrovascular growth onto the nasal side of the cornea. It`s cause has not been fully elucidated yet, but seems to be related to long -term ultraviolet ray exposure. When symptoms are not controlled with conservative treatment surgery is considered, but the recurrence rate is still high, and efforts have been made to avoid it. Mitomycin C (MMC) is a fibroblast proliferation inhibitor that can be used as adjuvant to surgery to reduce recurrence. We report here a case that describes pterygium surgery performed in both eyes of the same patient, being one with MMC and the other eye without it. Both pterygium were sent to laboratory analysis. The results and proliferation index were compared between the eyes.

ABSTRACT Pilomatrixoma is a rare benign tumor, which usually affects young women in the head and neck region. The eyelid is a common site of the disease, though it is very rare in the tarsal conjunctiva.The pilomatrixoma has clinical pleomorphism, which confuses this disease with other similar conditions. The diagnosis is made by pathological examination in most cases. The treatment is surgical, performed by total excision of the lesion with clear margins and recurrence is very uncommon.We present an unusual case of probable recurrent pilomatrixoma in the left upper tarsal conjunctiva.
RESUMO O pilomatricoma é uma neoplasia benigna rara, geralmente acomete mulheres jovens, ocorrendo na região da cabeça e pescoço. A pálpebra é um local comum de aparecimento do pilomatricoma, contudo, seu aparecimento na conjuntiva tarsal é muito raro. O diagnóstico é feito pelo exame anátomo-patológico na maioria dos casos, pois seu pleomorfismo clínico o confunde com outras alterações. O tratamento é cirúrgico, realizado por meio da exérese total da lesão com margens livres. São raros os casos de recidiva. Apresentamos um caso atípico de provável recidiva de pilomatricoma, localizado na conjuntiva tarsal superior à esquerda.

Objetivo: evaluar los resultados del tratamiento de la orbitopatía tiroidea y determinar cuáles son los factores que influyen sobre ellos. Métodos: se realizó un estudio observacional en una cohorte de 82 pacientes con orbitopatía tiroidea, durante el período 1997-2009. Resultados: en los casos con orbitopatía tiroidea activa, la corticoterapia se inició a los 19 meses de evolución y no fue satisfactoria en la mayoría de ellos, por lo que para preservar la visión se realizaron varias intervenciones quirúrgicas. Los factores que influyeron sobre la respuesta terapéutica fueron el tabaquismo y la actividad de la orbitopatía tiroidea (OR= 30,479 y OR= 14,557, respectivamente). Se obtuvieron buenos resultados con el uso de la toxina botulínica A y con la cirugía en la corrección del estrabismo y la retracción. Conclusiones: el diagnóstico y el tratamiento precoz es la conducta terapéutica ideal para los pacientes con orbitopatía tiroidea. El tabaquismo y la actividad de la orbitopatía tiroideainterfirieren en la respuesta terapéutica. La toxina botulínica A y la cirugía son efectivas en la corrección del estrabismo y la retracción palpebral de la orbitopatía tiroidea(AU)
Objective: to evaluate the results of the treatment of thyroid orbinopathy and to determine the factors affecting them. Methods: observational study of a cohort of 82 patients with thyroid orbinopathy during the 1997-2009 period. Results: corticosteroid-bases therapy began nineteen months after the onset of disease and was unsatisfactory in most of cases with active thyroid orbitopathy, so it was necessary to perform several surgeries to preserve the vision. The influential factors on the therapeutic response were smoking and thyroid orbinopathy activity (OR= 30,479 and OR= 14,557, respectively). Good results were attained with botilinum toxin A and strabismus correction surgery and retraction. Conclusions: early diagnosis and treatment is the best therapy for patients with thyroid orbinopathy. Smoking and thyroid orbinopathy negatively affect the therapeutic response. Botulinum toxin A and surgery are effective options in the strabismus correction and palpebral retractions of thyroid orbinopathy(AU)

We describe a patient with acute scleral dellen (SD) after pterygium excision with simple conjunctival closure. In addition, we present a PUBMED review on the medical literature on early SD after pterygium surgery. This case describes a 45-year-old man who presented with severe SD, 7 days after pterygium surgery with minimal cauterization of episcleral vessels and simple conjunctival closure. No other adjunctive therapy was used intraoperatively. The patient refused conjunctival flap coverage of the lesion. Therefore, medical treatment consisted of antibiotic ointment, patching, and daily follow-up. After 7 days, the patching was changed for intensive ocular lubrication. Five weeks later, the surrounding conjunctiva had completely covered the affected sclera. To the best of our knowledge, this is the first report of early SD following pterygium excision and simple conjunctival closure with no other adjunctive therapy. When performing pterygium excision with conjunctival coverage of the sclera, a close follow-up is recommended to rule out wound dehiscence and SD, even when surgical wound closure is considered to prevent SD. If this complication is detected, the treatment can be conservative.
Descrevemos um paciente com "dellen" escleral agudo (SD) após excisão de pterígio com fechamento conjuntival simples. Uma revisão adicional da literatura médica sobre SD precoce após a cirurgia de pterígio também é realizada. Este caso descreve um homem de 45 anos de idade, que apresentou SD grave, sete dias após a cirurgia de pterígio com cauterização mínima de vasos episclerais e fechamento conjuntival simples. Nenhuma outra terapia adjuvante foi utilizada no intraoperatório. O paciente recusou-se à cobertura de retalho conjuntival da lesão. Portanto, o tratamento médico consistiu em pomada antibiótica, oclusão e acompanhamento diário. Após sete dias, a oclusão foi mudada para a lubrificação ocular intensiva. Cinco semanas após, a conjuntiva cobriu completamente a esclera afetada. Ao melhor de nosso conhecimento, este é o primeiro relato de SD precoce após a excisão do pterígio e fechamento conjuntival simples com nenhuma outra terapia adjuvante. Ao realizar a excisão do pterígio com cobertura conjuntival da esclera, um acompanhamento frequente é recomendado para descartar a deiscência da ferida e SD. Se esta complicação for detectada, o tratamento pode ser conservador.

A 50-year-old male was referred with a previous history of conjunctival flap [CF] for a nonhealing fungal corneal ulcer with extreme corneal thinning in the right eye. The peritomy for the CF extended from 6:30 to 9-30 clock h on the cornea. The CF was disengaged, peritomy area deepithelialized, and CF was repositioned. He later underwent penetrating keratoplasty and achieved 20/40 best corrected visual acuity. The authors present a new concept for surgically repositioning CF s to the original site immediately after healing of the corneal ulcer

OBJECTIVE: To compare the efficacy of transconjunctival needling revision with 5-fluorouracil versus medical treatment in glaucomatous eyes with uncontrolled intraocular pressure due to encapsulated bleb after trabeculectomy. METHODS: Prospective, randomized, interventional study. A total of 40 eyes in 39 patients with elevated intraocular pressure and encapsulated blebs diagnosed at a maximum five months after primary trabeculectomy with mitomycin C were included. The eyes were randomized to either transconjunctival needling revision with 5- fluorouracil or medical treatment (hypotensive eyedrops). A maximum of two transconjunctival needling revisions per patient was allowed in the needling arm. All patients underwent follow-up for 12 months. Successful treatment was defined as an intraocular pressure ≤ 18 mmHg and a 20% reduction from baseline at the final follow-up. Clinicaltrial.gov: NCT01887223. RESULTS: Mean intraocular pressure at the final 12-month follow-up was lower in the transconjunctival needling revision group compared to the medical treatment group. Similar numbers of eyes reached the criteria for treatment success in both the transconjunctival needling revision group and the medical treatment group. CONCLUSIONS: Despite similar success rates in eyes randomized to transconjunctival needling revision with 5-fluorouracil compared to eyes receiving medical treatment, there was a significantly lower mean intraocular pressure at 12 months after transconjunctival needling revision. .

Bleb dysesthesia is a common but under recognized late complication of trabeculectomy, sometimes requiring surgical revision if conservative measures fail. We describe in detail a surgical technique for closure of a large conjunctival defect following bleb excision for refractory dysesthesia. Two subconjunctival 5-fluorouracil injections were given to improve bleb function. Eight months post-operatively, the intraocular pressure is well controlled on two agents, and the patient has had resolution of dysesthesia

A 65-year-old diabetic and hypertensive male presented with a sudden diminution of vision after sustaining a trivial fingernail injury to his only good-seeing [right] eye. The patient underwent phacotrabeculectomy with posterior chamber intraocular lens [PCIOL] implantation 22 years previously. In his right eye visual acuity at presentation was counting fingers at 1.5 m with an accurate projection of light. Intraocular pressure [IOP] was 4 mmHg. The anterior chamber was uniformly shallow with a peripheral iridocorneal touch. Angle details could not be visualized. The bleb was avascular, thin and cystic with a positive forced Seidel test. Fundus examination showed 360degree choroidal detachments. B-scan ultrasound revealed massive choroidals. Revision of dysfunctional filtering bleb by conjunctival advancement with bleb preservation and anterior chamber reformation with healon was performed. Postoperatively, the first day visual acuity improved to 6/36, the anterior chamber was deep, bleb was well covered with conjunctiva, the IOP was 10 mmHg and fundus examination revealed resolving choroidals. At the final follow up at 4 months, the patient did not require medication and visual acuity was 6/12, the bleb was functioning well with an IOP of 14 mmHg. Examination of the fundus revealed a cup-to-disc ratio of 0.5 with moderate non-proliferative diabetic retinopathy changes. The patient has been advised to maintain a strict glycemic control and return for routine follow up after 3 months.

OBJETIVO: Avaliar o uso do enxerto dermoadiposo no tratamento da cavidade anoftálmica. MÉTODOS: Estudo retrospectivo, do qual participaram 28 portadores de cavidade anoftálmica secundária, tratados com enxerto dermoadiposo. Os dados avaliados foram: idade, sexo, motivo da primeira cirurgia, tipo de cavidade, razão da opção pelo enxerto dermoadiposo, resultados e complicações. Os dados foram analisados segundo a frequência de ocorrência. RESULTADOS: dos 28 pacientes analisados, 19 (67,8 por cento) eram do sexo masculino, 46,4 por cento deles apresentando de 40 a 60 anos de idade. A principal causa da perda do olho foi o trauma (7 casos - 25,0 por cento). A cavidade onde mais se empregou o enxerto dermoadiposo foi a do tipo III (32,1 por cento). Como primeira cirurgia, a evisceração havia sido realizada em 13 casos, a enucleação em 11 e o enxerto de pele em dois pacientes e em outros dois, não havia informação sobre a primeira cirurgia a que haviam sido submetidos. A opção pelo enxerto dermoadiposo foi feita com a finalidade de repor volume na cavidade e, ao mesmo tempo, conseguir maior superfície anterior da cavidade, já que a maioria possuía cavidades contraídas. A maioria dos pacientes (53,6 por cento) não apresentou complicações, tendo sido a necrose do enxerto a complicação mais observada (32,1 por cento). O resultado final da cirurgia foi considerado bom em 71,4 por cento dos pacientes e ruim em 7,1 por cento. CONCLUSÃO: O enxerto dermoadiposo é uma técnica cirúrgica simples e de bons resultados para reposição de volume em cavidades anoftálmicas. Os autores estimulam o ensino da mesma nos serviços de treinamento de jovens cirurgiões.
PURPOSE: To evaluate the dermofat graft in the anophthalmic socket treatment. METHODS: A retrospective study including 28 anophthalmic cavity carriers treated with dermofat graft was carried out. The patients were analyzed according to age, sex, socket contraction degree, first surgery performed, reason for graft choice, procedure´s results and complications. The data were analyzed according to the frequency of occurrence. RESULTS: Nineteen (67.8 percent) of the 28 analyzed patients were male. According to age the majority of patients were between 40 to 60 years old (13 patients - 46.4 percent) and the most common cause of eyeball loss was trauma (seven cases - 25 percent). Anophthalmic socket type III was the most frequently observed (32.1 percent). The evisceration was the first procedure in 13 cases, enucleation in 11 and skin graft was done in two patients. Two patients came to the service after evisceration and did not provide any information about the first surgery. The choice to use the dermofat graft was to replace volume at the socket of 12 patients (42.8 percent). Most of the patients (53.6 percent) had no complications and graft necrosis was the problem most frequently observed (32.1 percent). The surgery was considered good in 71.4 percent and not good in only 7.1 percent. CONCLUSION: the dermofat graft is an efficient and easy technique to reconstruct the anophthalmic cavity. The authors suggest this procedure must be introduced in the medical training services since it provide good results.

El objetivo del presente informe es describir un caso de queratopatía cristalina causada por microorganismos pertenecientes al grupo Streptococcus mitis en una paciente que concurrió a la consulta oftalmológica por molestias en su ojo derecho. Al examen oftalmológico presentó un punto de sutura interrumpida de nylon 10-0 sin tensión y con secreciones mucosas adheridas. El punto flojo fue retirado bajo normas de asepsia. Se indicó colirio de moxifloxacina al 0,5 %; el ojo tuvo una evolución adecuada, con una correcta epitelización. Sin embargo, luego de 15 días desarrolló un infiltrado blanquecino arboriforme. Se tomó una muestra en el quirófano, enhebrando el trayecto intraestromal de la sutura retirada con sutura de vicryl 7-0. Se indicaron colirios de vancomicina con 50 mg/ml. El infiltrado se mantuvo estable durante 45 días, luego se incrementó el tamaño y se produjo necrosis tisular con peligro de perforación corneal. Se realizó un recubrimiento conjuntival bipediculado. La paciente evolucionó favorablemente y luego de la retracción espontánea del recubrimiento, se observó leucoma cicatrizal y neovasos corneales.
Crystalline keratopathy: an infrequent corneal infection produced by the Streptococcus mitis group. The objective of this report is to describe a case of crystalline keratopathy caused by the Streptococcus mitis group corresponding to a patient who attended hospital for discomfort in his right eye. The ophthalmological examination showed an interrupted stitch of 10-0 nylon suture without tension and with attached mucus secretions. The loose suture was removed under aseptic conditions. Moxifloxacin 0.5 % eye drops were topically indicated. The treated eye successfully epithelialized and evolved favorably. However, after 15 days, a white tree-shaped infiltrate developed. A corneal sample was taken in the operating room, threading the intrastromal path of the removed stitch with a 7-0 vicryl suture. Vancomycin 50 mg/ml drops were indicated. The infiltrate, which was stable for 45 days, later increased its size and tissue necrosis occurred with danger of corneal perforation. A bipedicle conjunctival flap was performed in the affected corneal area, which evolved favorably. After spontaneous conjunctival flap retraction, only corneal scarring and neovascularization outside the visual axis were observed.
