Corneal Perforation associated with "Silent Brain Syndrome" / Perfuração corneana associada à "síndrome do cérebro silencioso"

ABSTRACT This case report describes the clinical characteristics and ophthalmic management of a patient who developed corneal perforation due to severe enophthalmos consistent with "silent brain syndrome." A 27-year-old man with a history of congenital hydrocephalus and ventriculoperitoneal shunt was referred with complaints of "sinking of the eyeballs" and progressively decreasing vision in the left eye. Examination revealed severe bilateral enophthalmos in addition to superonasal corneal perforation with iris prolapse in the left eye. The patient underwent therapeutic keratoplasty the next day. Orbital reconstruction with costochondral graft and shunt revision of the intracranial hypotension were performed the next month to prevent further progression.

RESUMO Este relato de caso descreve as características clínicas e o manejo cirúrgico de um paciente que teve perfuração da córnea devido à enoftalmia grave consistente com a "síndrome do cérebro silencioso". Um homem de 27 anos com história de hidrocefalia congênita e derivação ventrículo-peritoneal foi encaminhado com queixas de "afundamento dos globos oculares" e diminuição progressiva da visão no olho esquerdo. O exame revelou enoftalmo bilateral importante, além de perfuração superonasal da córnea com prolapso iriano no olho esquerdo. A paciente foi submetida à ceratoplastia terapêutica no dia seguinte. Foi realizado no mês seguinte a reconstrução da órbita com enxerto costocondral e revisão do shunt para evitar progressão e piora do caso.

Queratoplastia penetrante con fines ópticos. Presentación de cuatro casos / Penetrating keratoplasty with optical aims. Presentation of four cases

RESUMEN La queratoplastia penetrante ha sido el procedimiento empleado, de forma casi universal, para el tratamiento de las patologías corneales que afectan de forma irreversible a la visión. Se reportaron 4 casos clínicos de pacientes con afecciones corneales con compromiso visual severo, dado por visión de cuenta dedos y percepción luminosa. Luego de la evaluación completa en cada caso, se decidió realizar la queratoplastia penetrante con fines ópticos, con el objetivo de recuperar la transparencia de la córnea y la calidad visual. No existieron complicaciones transquirúrgicas y fueron seguidos según protocolo de evaluación postoperatoria de trasplante corneal. Los resultados y evaluación fueron satisfactorios, al año mantenían la transparencia del injerto y se logró mejoría considerable de la agudeza visual (AU).

ABSTRACT Penetrating keratoplasty has been a procedure used, almost universally, to treat corneal diseases affecting vision in an irreversible way. Four clinical cases are reported of patients with corneal affections severely compromising vision, given by short vision and luminous perception. After completely evaluating each case, the authors decided to perform the penetrant keratoplasty with optical aims, to recover cornea transparency and the vision quality. There were not transurgical complications and the patients were followed up according to the protocols of post-surgery evaluation of corneal graft. The results and evaluation were satisfactory; after a year, the transparency of the graft was maintained and visual acuity substantially improved (AU).

Queratoplastia en perforación corneal / Keratoplasty in corneal perforation

RESUMEN La perforación corneal es una emergencia médica que por su gravedad puede poner en peligro la integridad del globo ocular. Se informan los resultados en una serie de 25 pacientes y sus 25 ojos con perforación corneal de diversas etiologías, los cuales constituyen el mayor porcentaje de pacientes con queratopatía herpética a quienes se les realizó queratoplastias primarias terapéuticas, así como dos retrasplantes ópticos, en el Hospital Clínico Quirúrgico "Hermanos Ameijeiras". El 83,4 por ciento de los ojos fueron conservados con agudeza visual desde 0,05 a 0,8 con corrección óptica(AU)

ABSTRACT Corneal perforation is a medical emergency whose severity may jeopardize the integrity of the eyeball. Results are presented of a series of 25 patients and their 25 eyes with corneal perforation of varying etiologies. This group constitutes the largest percentage of patients with herpetic keratopathy undergoing primary therapeutic keratoplasties. Two of them underwent optical retransplantation at Hermanos Ameijeiras Clinical Surgical Hospital. Of the total eyes, 83.4 percent were preserved, with a visual acuity of 0.05 to 0.8 with optical correction(AU)

Corneal Collagen Cross-linking for Corneal Ulcer from Moraxella Group

PURPOSE: To report a case of corneal collagen cross-linking for corneal ulcer caused by the Moraxella group.CASE SUMMARY: A 77-year-old male had decreased visual acuity for several days in his right eye. The patient showed severe stromal ring infiltrates with a corneal epithelial defect measuring (5.0 × 7.0 mm), a corneal endothelial plaque, and a hypopyon measuring less than 1.0 mm in height in the anterior chamber of the right eye. There was no abnormal finding in the right eye using B-scan ultrasonography. Before starting treatment, a corneal culture was conducted. The culture tests showed the presence of the Moraxella group. Because the patient was diagnosed with a corneal ulcer caused by the Moraxella group, corneal collagen cross-linking (CXL) was performed. The antimicrobial susceptibility test confirmed that this Moraxella group was sensitive to ceftazidime, so the patient was treated with 5% ceftazidime eye drops and 0.5% moxifloxacin eye drops every 2 hours for 9 months after corneal collagen CXL. The uncorrected visual acuity was 0.1 in the right eye, and there was almost no corneal stromal melting on anterior segment optical coherence tomography.CONCLUSIONS: This is the first known case of a corneal ulcer, in the Republic of Korea, caused by the Moraxella group and treated with corneal collagen CXL. Corneal collagen CXL should be considered as a surgical treatment for patients who have an impending corneal perforation due to a corneal ulcer because it is a simple procedure and causes fewer serious complications than other treatments.

Úlcera corneal bilateral en un anciano con pénfigo vulgar / Bilateral corneal ulcer in an old man with pemphigus vulgaris

Se describe el caso clínico de un paciente de 72 años de edad, con diagnóstico de pénfigo vulgar, quien fue asistido en la consulta de Oftalmología del Hospital General Docente Dr. Juan Bruno Zayas Alfonso de Santiago de Cuba porque padecía enrojecimiento ocular, unido a disminución de la visión y secreciones abundantes de aproximadamente 5 días de evolución. En el examen oftalmológico se confirmó la presencia de úlcera corneal bilateral por perforación infecciosa. Se indicó tratamiento con colirios de antibióticos (ceftazidima y amikacina), antiinflamatorio no esteroideo, agentes antihipertensivos y lente de contacto, con lo cual mejoraron las lesiones de ambos ojos. El proceso infeccioso pudo deberse a cierta susceptibilidad a los esteroides e inmunosupresores sistémicos, como terapia asociada al pénfigo vulgar, o al mecanismo autoinmune característico de esta dermatopatía.

The case report of a 72 years patient is described, with diagnosis of pemphigus vulgaris who went to the Ophthalmology Service of Dr. Juan Bruno Zayas Alfonso Teaching General Hospital in Santiago de Cuba because he suffered from ocular redness, together with a decrease vision and abundant secretions of approximately 5 days of history. In the ophthalmological examination the presence of bilateral corneal ulcer was confirmed due to infectious perforation. Treatment was indicated with antibiotic eyewashes (ceftazidime and amikacine), non esteroidal anti-inflammatory drugs, antihypertensive agents and contact lens, with which the injuries of both eyes improved. The infectious process could be due to certain susceptibility to the steroids and systemic inmunosupressors, as therapy associated with pemphigus vulgaris, or to the autoinmune mechanism characterizing this dermatopathy.

ABSTRACT We present the clinical case of a male patient, aged 27 years, with corneal ectasia and keratoglobus in both eyes. The clinical manifestation was progressive and slow decrease of the visual acuity in both eyes and pain in the left eye. At the ophthalmologic examination, acute corneal hydrops was found in the left eye, and also other complications that are proper of this anomaly. An ophthalmologic study was carried out that lead to an accurate diagnosis. The correspondent therapy was applied and several therapeutic options were suggested (AU).

Recubrimiento conjuntival en afecciones corneales / Conjunctival flap in corneal diseases

Objetivo: Determinar la eficacia del recubrimiento conjuntival en afecciones corneales. Métodos: Se realizó un estudio descriptivo retrospectivo de corte transversal, entre los años 2015 y 2017 en el Instituto Cubano de Oftalmología Ramón Pando Ferrer. La muestra quedó conformada por 52 pacientes quienes asistieron a la consulta externa del Servicio de Córnea de la mencionada institución. Resultados: Predominó el sexo masculino con el 63,5 por ciento de los pacientes. El grupo etario comprendido entre los 50 y 59 años de edad representó el 26,9 por ciento. Entre las afecciones corneales, el mayor porcentaje correspondió al descemetocele (30,8 por ciento), seguido de las úlceras corneales (23,1 por ciento). La técnica más empleada fue el recubrimiento conjuntival total representada por el 46,2 por ciento de las cirugías realizadas. El 80,8 por ciento de los casos evolucionó a la cicatrización corneal. La complicación más frecuente fue la retracción del colgajo (9,6 por ciento). Conclusiones: Los recubrimientos conjuntivales resultan un simple y eficaz procedimiento quirúrgico en pacientes que no responden a tratamiento médico o perforaciones corneales menores o iguales a 3 mm. Es un procedimiento extraocular que puede realizarse de urgencia para disminuir el dolor y la inflamación y puede ser revertido para realizar cirugías con fines visuales en un segundo tiempo(AU)

Objective: To determine the effectiveness of the conjunctival flap to treat corneal diseases. Methods: Retrospective, descriptive and cross-sectional study was carried out from 2015 to 2017 at "Ramon Pando Ferrer" Cuban Institute of Ophthalmology. The sample was made up of 52 patients who went to the outpatient Service of the Corneal Department of the institution. Results: Males represented 63.5 % of patients. The 50-59 y group represented 26.9 percent. Among the corneal diseases, descemetocele exhibited the highest percentage (30.8 percent) followed by corneal ulcers (23.1 percent). The most used surgical technique was the total conjunctival flap in 46.2 percent of surgeries. 80.8 percent of patients evolved into corneal scarring. The most frequent complication was flap retraction (9.6 percent). Conclusions: The conjunctival flaps represent a simple and effective surgical procedure in patients who do not respond to medical treatment or in corneal perforations equal or under 3 mm. This is an extraocular procedure that may be performed in emergency in order to release pain and inflammation and may be reversed later to perform surgeries aimed at visual problems(AU)

Treatment of perforated cornea with an autologous lamellar scleral graft: histologic findings / Tratamento de córnea perfurada com enxerto autônomo de esclera lamelar: achados histológicos

ABSTRACT We report a case of central corneal perforation treated with an autologous lamellar scleral graft and histologic findings obtained after a subsequent penetrating keratoplasty. A corneal perforation within a large Pseudomonas ulcer in a 55-year-old male rigid gas permeable contact lens wearer was sealed by a lamellar scleral graft from the same eye, followed by an uneventful penetrating keratoplasty 6 months later. Histology of the excised button revealed that the well-apposed graft, which maintained the irregular arrangement of the scleral collagen fibers, was embedded in the corneal stroma over the deep blood vessels and a rupture in Descemet's membrane. The clinical and histologic findings showed that autologous lamellar scleral grafts can be successfully used for the emergency treatment of corneal perforation when a corneal transplant is not available. The distinctive scleral structure revealed by histology and the inadequate graft transparency indicate that visual rehabilitation of eyes with a central corneal perforation can be achieved only by a subsequent optic penetrating keratoplasty.

RESUMO Relatamos um caso de perfuração corneana central tratada com enxerto autólogo lamelar de esclera e os achados histológicos obtidos após ceratoplastia penetrante (CP) subsequente. Uma perfuração da córnea devido a uma grande úlcera por Pseudomonas em um usuário de lentes de contato rígidas gás permeável de 55 anos de idade foi selada por um enxerto escleral lamelar do mesmo olho, seguida de ceratoplastia penetrante, sem intercorrências, seis meses depois. A histologia do botão excisado revelou que um enxerto bem posicionado, que manteve o arranjo irregular das fibras de colágeno escleral, foi incorporado no estroma corneano sobre os vasos sanguíneos profundos e uma ruptura na membrana de Descemet. Os achados clínicos e histológicos demonstraram que o enxerto autônomo de esclerose lamelar pode ser usado com sucesso como tratamento de emergência da perfuração da córnea, quando o transplante de córnea não é possível. A estrutura escleral característica revelada pela histologia e a transparência inadequada do enxerto indicam que a reabilitação visual dos olhos com uma perfuração corneana central só pode ser alcançada através de uma ceratoplastia penetrante óptica subsequente.

A Case of Monocular Gonococcal Conjunctivitis in an Adult Male / 계명의대학술지

Gonococcal conjunctivitis is rare in adults and, if not treated properly, can cause corneal perforation. Gonococcal conjunctivitis typically presents with a severe mucopurulent discharge, similar to that associated with viral conjunctivitis. Here, we describe a case of monocular gonococcal conjunctivitis, including its clinical characteristics and slit-lamp images, which was initially misdiagnosed as epidemic conjunctivitis. A 20-year-old man was referred to our hospital with no improvement in monocular infection and purulent ocular discharge after 2-wk treatment using antibiotic and 0.1% fluorometholone eye drops at the local ophthalmic clinic. Initially, 0.5% loteprednol eye drops were used since we suspected viral conjunctivitis. Following this treatment, conjunctival infection worsened and a yellow-white ocular discharge covered the conjunctiva and cornea surface. Additional history taking revealed that the patient had sexual contact with a prostitute 1 wk prior to symptom presentation and, after the encounter, he took antibiotics for genital discharge at the local urology clinic, but self-discontinued treatment. A Gram staining showed gram-negative diplococci and culture of collected ocular discharge from the palpebral conjunctiva revealed growth of Neisseria gonorrhoeae, confirming gonococcal conjunctivitis. Following this, the patient was systemically treated with 3rd generation cephalosporin antibiotics. After 3-d treatment, conjunctival infection and purulent ocular discharge had significantly improved. When clinical symptoms are aggravated following steroid eye drop treatment for suspected monocular viral conjunctivitis, gonococcal conjunctivitis must be considered as a differential diagnosis

A Case of Spontaneous Corneal Perforation Combined with Primary Pterygium

PURPOSE: We report a case of spontaneous corneal perforation combined with primary pterygium. CASE SUMMARY: A 66-year-old male presented with a foreign body sensation in his right eye. He had no systemic or ocular inflammatory diseases. He had undergone penetrating keratoplasty following amniotic membrane transplantation for corneal perforation at 1 day after pterygium excision in his left eye. The uncorrected visual acuity (UCVA) and intraocular pressure (IOP) in his right eye were 0.8 and 2 mmHg, respectively. Active leakage of an aqueous humor on the head of the pterygium was found on slit lamp examination. With the impression of spontaneous corneal perforation combined with primary pterygium, emergent amniotic membrane transplantation was performed. Diffuse corneal thinning around the 2 mm-sized perforation site was found 3mm away from the limbus in the 5 o'clock after removing the pterygium. The perforation site was covered with amniotic membrane after applying fibrin glue. UCVA and IOP in his right eye were 1.0 and 9 mmHg, respectively, at postoperative 6 months. No definite recurrence of pterygium or additional corneal perforation was found. CONCLUSIONS: Spontaneous corneal perforation may be related to primary pterygium.

C-type Anterior Lamellar Keratoplasty Using Cryopreserved Leftover Cornea for Terrien's Marginal Degeneration

PURPOSE: To report a case of Terrien's marginal degeneration treated with C-type anterior lamellar keratoplasty using cryopreserved leftover cornea. CASE SUMMARY: A 63-year-old female visited our clinic because of left ocular discomfort and visual deterioration over several years. The patient had +2.25 Dsph = -5.00 Dcyl × 111° of astigmatism, and best corrected visual acuity was 20/20. Microscopic slit lamp examinations revealed an approximately 10.0 mm width semilunar shaped stromal opacity with surrounding stromal lipid deposit, as well as superficial neovascularization with thinning at superior perilimbal cornea. Anterior segment optical coherence tomography confirmed extreme thinning at the opacified cornea. The patient was diagnosed with Terrien's marginal degeneration. To prevent corneal perforation, C-type anterior lamellar keratoplasty using cryopreserved leftover cornea was performed. After 18 months after operation, donor graft was successfully attached via the anterior segment optical coherence tomography and microscopic slit lamp examination and graft rejection was not observed. CONCLUSIONS: C-type anterior lamellar keratoplasty using a cryopreserved cornea can be an effective therapeutic strategy for Terrien's marginal degeneration.

Fonsecaea pedrosoi as a rare cause of acute conjunctival ulceration / Fonsecaea pedrosoi como agente raramente associado à úlcera conjuntival aguda

ABSTRACT Conjunctival ulceration accompanied with secretion and pain was observed in a 30-year-old male, 3 days after a perforating corneal trauma. Cultures of conjunctival ulcer samples grew Fonsecaea pedrosoi, a major causative agent of chromoblastomycosis that is typically transmitted during trauma. The conjunctival ulcer was successfully treated with amphotericin B, itraconazole, and fluconazole. This case report summarizes the diagnosis and treatment of a conjunctival ulcer due to F. pedrosoi, which is a rare complication of contaminated ocular trauma. To the best of our knowledge, this is the first reported case of F. pedrosoi causing acute conjunctival ulceration in the literature.

RESUMO O quadro clínico de uma úlcera conjuntival acompanhada de secreção e dor foi observado em homem de 30 anos de idade, 3 dias após um trauma perfurante da córnea. As culturas de uma amostra retirada da úlcera conjuntival foi positiva para Fonsecaea pedrosoi, uma cromoblastomicose, geralmente transmitido após traumatismos. O caso foi tratado com sucesso com a anfotericina B, itraconazol e fluconazol. Este relato de caso reporta o diagnóstico e tratamento de uma úlcera conjuntival causada por F. pedrosoi, que raramente é visto nos olhos expostos a traumatismos contaminados. Até onde sabemos, este é o primeiro caso relatado na literatura de F. pedrosoi causando úlcera conjuntival aguda.

Ocular manifestation of Ichthyosis

Purpose: Ichthyosis is a rare dermato-ocular disease. This study evaluates the presenting ocular signs, symptoms, complications and prognosis of ichthyosis in a case series from Saudi Arabia

Methods: A retrospective chart review was performed for 11 patients with ichthyosis who presented to King Khaled Eye Specialist Hospital, Riyadh, Saudi Arabia, over the last 20 years

Results: The most common presenting ocular diagnosis was ectropion of both the lids. Two patients developed corneal perforation with poor prognosis. Most of the patients underwent skin grafting to repair eyelid ectropion. The visual prognosis was excellent because timely surgical interventions were performed. Hence the rate of corneal complications such as perforation was low

Conclusion: The most ocular presentation of ichthyosis is ectropion of both the upper and lower lids. Despite good visual prognosis, there were some devastating corneal complications such as perforation with unpredictable outcomes

Tectonic Lamellar Keratoplasty Using Cryopreserved Cornea in a Large Descemetocele

We describe herein a case of an impending corneal perforation with a large descemetocele in a patient with previous penetrating keratoplasty (PKP) that subsequently was treated with an emergent lamellar keratoplasty using frozen preserved cornea. A 76-year-old male patient, who had a PKP, presented with a completely whitish and edematous graft accompanied by large epithelial defects. Although antibiotics and antiviral agents were tried for three days, the corneal stroma abruptly melted, except for the Descemet's membrane and endothelium. Cryopreserved corneal tissue that was kept at -80degrees C was thawed and sutured on top of the remaining Descemet's membrane and endothelium. Pathological and microbiological tests were conducted using the remaining donor and recipient corneal tissues. After tectonic corneal transplantation on top of a large descemetocele, a healthy graft and relatively clear interfaces between graft-host junctions were maintained without serious adverse reactions throughout 6 month follow-up period. Microbiological evaluations of donor tissue at the time of thawing and tissue preparation were done, and the results were all negative. Tissue that was taken intraoperatively from the recipient cornea also showed negative microbiological results. In conclusion, tectonic lamellar keratoplasty, using cryopreserved corneal tissue, only onto the remaining Descemet's membrane and endothelium in an emergent condition, was a safe and effective treatment.

A Case of Descemet's Membrane Detachment during Lidocaine Injection for Hordeolum Incision and Drainage

PURPOSE: To report a case of Descemet's membrane detachment and corneal edema caused by an iatrogenic corneal perforation created while performing a local anesthetic (lidocaine) injection into the eyelid for a hordeolum incision and a drainage procedure. The detachment resolved after 14% C₃F₈ gas and air injections into the anterior chamber. CASE SUMMARY: An 8-year-old female visited our clinic after the onset of severe pain and decreased visual acuity while receiving a local anesthetic injection into the upper eyelid in preparation for a hordeolum incision and drainage procedure. Corneal optical coherence tomography (OCT) showed Descemet's membrane detachment. Three days after the first visit, the corneal epithelium had entirely healed. However, Descemet's membrane detachment persisted even after three weeks of follow-up. A corneal OCT was repeated after three weeks and showed a partial Descemet's membrane rupture. A more aggressive treatment method was deemed necessary, and gas and air injections into the anterior chamber were performed. After 48 hours, aside from some Descemet's membrane rolling at the site of rupture, overall reattachment of Descemet's membrane was noted. After three months of follow-up, the patient showed a stable corneal state and normalized vision. CONCLUSIONS: Descemet's membrane detachment and rupture resulting from an iatrogenic corneal perforation during an injection of lidocaine to the eyelid led to decreased visual acuity from corneal edema. As a more aggressive treatment method, 14 % C₃F₈ gas and air injections into the anterior chamber were performed and resulted in near complete reattachment of Descemet's membrane's and normalization of the patient's visual acuity.

Keratitis Caused by Paecilomyces lilacinus after Cataract Surgery in a Patient with Systemic and Autoimmune Disease

PURPOSE: To report a case of Paecilomyces lilacinus fungal keratitis after cataract surgery in a patient with chronic systemic and autoimmune disease who was treated with medical therapy and penetrating keratoplasty. CASE SUMMARY: A 72-year-old female was referred for decreased visual acuity and ocular pain in the left eye. She underwent cataract surgery in the left eye 1 month earlier and was treated for 2 weeks for corneal edema and stromal infiltration around the corneal suture. She had a chronic systemic disease with hypertension, hyperlipidemia, hepatitis C and rheumatoid arthritis. Suspecting infectious keratitis, the patient was instructed to stop applying topical and systemic steroids and use topical amphotericin B (0.15%) and moxifloxacin (0.5%). However, without improvement, amphotericin B (0.15%) and moxifloxacin (0.5%) were changed to natamycin (5%) and topical voriconazole (2%) and systemic voriconazole was added. However, her systemic status deteriorated and corneal melting developed, scleral graft implantation and amniotic membrane implantation were performed to prevent corneal perforation 6 weeks after the initial visit. Paecilomyces lilacinus was identified in culture at 7 weeks and penetrating keratoplasty was performed 12 weeks after the initial visit. After penetrating keratoplasty, corneal status was stable for 6 months and no signs of recurrence were observed. CONCLUSIONS: In a patient with Paecilomyces lilacinus fungal keratitis and chronic systemic and autoimmune disease, penetrating keratoplasty showed good prognosis when the disease was refractory to topical and systemic antifungal agents.

A Novel Tectonic Keratoplasty with Femtosecond Laser Intrastromal Lenticule for Corneal Ulcer and Perforation / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Small incision refractive lenticule extraction (SMILE) is an effective laser procedure that treats myopia. This research was to describe a novel approach to treat corneal ulcer or perforation using the corneal lenticules obtained from SMILE and to evaluate the safety and effectiveness of tectonic keratoplasty with femtosecond laser intrastromal lenticule (TEKIL).</p><p><b>METHODS</b>A total of twenty patients (22 eyes) were monitored for at least 6 months and were assessed using slit lamp microscopy, optical coherence tomography, and best-corrected visual acuity (BCVA). Postoperative complications throughout the study period were recorded.</p><p><b>RESULTS</b>Corneal ulcer in 14 patients (16 eyes) and corneal perforation in six patients (6 eyes) were treated with TEKIL. The patients were ten females and ten males, with a mean age of 58.5 ± 16.3 years (range: 16-81 years). In this study, the most causes of corneal ulcer or perforation were immunologic causes (54.5%). After TEKIL procedure, global integrity was achieved in all cases. No immune rejection or perforation was detected. The mean BCVA improved from 0.17 ± 0.20 preoperatively to 0.27 ± 0.25 postoperatively at the final follow-up (t = 2.095, P = 0.052). The postoperative BCVA improved in 12 eyes (54.5%) and maintained in nine eyes (40.9%). Vision function successfully maintained in all eyes (100%). In three cases, corneal ulcers were treated by reoperation of TEKIL at 3 months after the initial surgery for the reason that the residual corneal thickness was <250 μm.</p><p><b>CONCLUSIONS</b>TEKIL seems to be an effective treatment for corneal ulcer and perforation in the condition of emergency and donor shortage.</p>

Síndrome da ceratomalácia (Corneal Melting) periférica na artrite psoriásica tratada com adalimumabe / Peripheral corneal melting syndrome in psoriatic arthritis treated with adalimumab

RESUMOA síndrome do corneal melting periférica é uma rara condição imune caracterizada por afinamento da margem da córnea e, às vezes, perfuração. Está associada a doenças reumáticas e não reumáticas. Poucos casos de síndrome do corneal melting periférica foram relatados em pacientes com psoríase. A patogênese não foi completamente entendida, mas as metaloproteinases podem ter papel patogênico. A terapia Anti-TNF diminuiu os níveis de metaloproteinases na pele e no sangue em psoríase. Reportamos o caso de um homem de 61 anos com síndrome do corneal melting periférica associada à artrite psoriásica que recebeu adalimumabe para controlar a inflamação na pele e no olho. Pelo que sabemos, este é o primeiro caso de síndrome do corneal melting periférica em artrite psoriática tratado com adalimumabe mostrando evolução nas lesões cutâneas e cura total da perfuração da córnea em três meses.

ABSTRACTPeripheral corneal melting syndrome is a rare immune condition characterized by marginal corneal thinning and sometimes perforation. It is associated with rheumatic and non-rheumatic diseases. Few cases of peripheral corneal melting have been reported in patients with psoriasis. The pathogenesis is not fully understood but metalloproteinases may play a pathogenic role. Anti-TNF therapy has shown to decrease skin and serum metalloproteinases levels in psoriasis. We report a 61-year-old man with peripheral corneal melting syndrome associated with psoriatic arthritis who received adalimumab to control skin and ocular inflammation. To our knowledge, this is the first case report of peripheral corneal melting syndrome in psoriatic arthritis treated with adalimumab showing resolution of skin lesions and complete healing of corneal perforation in three months.

A Case of Sympathetic Ophthalmia due to Corneal Perforation in a Patient with Meningioma

PURPOSE: To describe a case of sympathetic ophthalmia due to corneal perforation caused by exposure keratitis in a patient with recurrent sphenoid wing meningioma. CASE SUMMARY: A 34-year-old female patient presented with proptosis in her left eye caused by left sphenoid greater wing meningioma despite tumor debulking surgery and radiation treatment. The cornea was perforated with prolapsed iris due to exposure keratitis, thus enucleation of the left eye was performed. After 2 weeks, an inflammatory reaction occurred in both eyes, keratic precipitates on corneal endothelium, exudative retinal detachment, and multiple granulomatous nodules on the right eye retina. The patient was diagnosed with sympathetic ophthalmia, thus enucleation of the left eye and debulking of the tumor were performed followed by a high-dose intravenous steroid therapy. At 5 months postoperatively, slit lamp biomicroscope showed no chamber reaction; improved disc swelling and exudative retinal detachment in the right eye were observed. CONCLUSIONS: Despite conservative treatment for exposure keratitis due to proptosis caused by malignant sphenoid meningioma, corneal perforation can develop. Because sympathetic ophthalmia can occur, the other eye should be monitored.
