Long-term outcome of autologous fascia lata grafting with conjunctival flap overlay in horses with ulcerative keratitis and keratomalacia.

OBJECTIVES: To describe the technique, postoperative complications, and outcome after autologous fascia lata grafting with conjunctival flap overlay in horses with ulcerative keratitis and keratomalacia. STUDY DESIGN: Retrospective case series. ANIMALS: Eleven horses with ulcerative keratitis and keratomalacia. METHODS: Horses included had undergone fascia lata grafting with conjunctival flap overlay due to impending or recent corneal perforation. Preceding therapy, lesion characteristics, postoperative complications, and short- and long-term outcomes were recorded. RESULTS: Postoperative complications included complete (1/11) or partial (2/11) dehiscence of the conjunctival flap and fascia lata graft, postoperative pneumonia (1/11), intermittent hypercreatinemia (2/11) and mild uveitis after trimming of the conjunctival flap (9/10). The donor sites healed without complications (11/11). A satisfactory short-term outcome (at cessation of medical therapy) was achieved in all horses (11/11). Long-term follow-up (median 29 months, range 7-127 months) was available for 10/11 horses. A comfortable eye with functional vision was achieved in 9/10 horses with long-term follow-up, including 3/4 horses with prior corneal perforation and 1/11 horses in which the fascia lata graft completely dehisced 15 days after surgery. Enucleation was required in a single horse (1/10) after phthisis bulbi developed 7 months postoperatively. CONCLUSION: Fascia lata grafting with conjunctival flap overlay appears to be a viable solution for globe preservation in horses with ulcerative keratitis and keratomalacia. Long-term ocular comfort with functional visual outcomes can be achieved in most cases with limited concerns for donor site morbidity while bypassing acquisition, storage or lesion-size limitations related to other biomaterials.

Peripheral Ulcerative Keratitis Associated With Lichen Planus.

PURPOSE: The aim of this study was to report a case of peripheral ulcerative keratitis (PUK) associated with lichen planus. METHODS: A 42-year-old woman with histological confirmation of lichen planus from an oral buccal mucosa biopsy presented with bilateral peripheral stromal thinning and an epithelial defect, in keeping with PUK. RESULTS: All screening for known causes of PUK were negative, and lichen planus was presumed as the etiological factor. Oral prednisolone 1 mg/kg was initiated, alongside topical steroids and topical ciclosporin. The PUK resolved after 3 months, and a slow-tapering regimen of oral prednisolone was needed to prevent a relapse of ocular surface inflammation. Topical steroids were also tapered and discontinued after 5 months, and the ocular surface remained stable with topical ciclosporin with no relapse after 1 year. CONCLUSIONS: Ocular manifestations of lichen planus are rare and mostly involve the conjunctiva; however, PUK might also develop, presumably due to its similar mechanisms with other T-cell autoimmune diseases. Systemic immunosuppression is required initially but further control of the ocular surface can be achieved successfully with topical ciclosporin.

Fungal Keratitis and Corneal Perforation as a Rare Complication of Corneal Collagen Cross-Linking Treatment.

PURPOSE: The aim of this study was to report a case of fungal keratitis with subsequent corneal perforation after corneal collagen cross-linking (CXL) treatment performed for keratoconus. CASE REPORT: A 20-year-old woman presented with redness and discharge in the left eye. She had a history of bilateral CXL procedure performed for keratoconus elsewhere 4 days earlier. The visual acuity was hand motion in the left eye. Slit-lamp examination revealed extended corneal melting with surrounding infiltrates. The patient was hospitalized, and corneal epithelial scraping samples were sent for microbiological assessment. In the meantime, empirical antibiotic therapy (fortified topical antibiotics: vancomycin 50 mg/mL, ceftazidime 50 mg/mL, and fluconazole 2 mg/mL q1 hour) was initiated. In direct microscopy of the corneal scraping, septate hyaline fungal hyphae were detected and topical fluconazole was switched to topical voriconazole (10 mg/mL). Three days after hospitalization, corneal melting progressed to perforation and corneal suturing with 10-0 monofilament was performed to reform the anterior chamber. Complete resolution of keratitis with residual scarring was noticed in 2 weeks. Three months later, penetrating keratoplasty was performed to obtain better visual acuity. CONCLUSIONS: CXL with riboflavin has become a common procedure to prevent keratoconus progression by strengthening the biomechanical specialties of the cornea. Although the treatment itself has been used in the management of microbial keratitis and related corneal melting, fungal keratitis and corneal perforation after a CXL procedure for keratoconus might also be detected. Clinicians should be aware of this rare but devastating complication of CXL treatment and start prompt treatment when suspected.

Haemophilus Influenzae-Induced Corneal Ulcer and Endophthalmitis Triggered by Hair Dye.

ABSTRACT: The present report describes a 79-year-old woman developed eye pain in her right eye after accidental exposure to the hair dye when she dyed her hair. Her visual acuity was no light perception and intraocular ocular pressure was 10 mmHg in her right eye. Slit-lamp biomicroscopy revealed a huge corneal ulcer with the central cornea almost perforated and severe hypopyon in anterior chamber and moderate opacity in vitreous. Time-of-flight mass-spectrum of cornea scraping confirmed that the pathogen was haemophilus influenzae. Right-eye enucleation was performed. Topical chloramphenicol eye drops (0.25%) and ciprofloxacin (0.3%) and the ceftezole intravenous infusion were applied. The infection was controlled and the patient recovered well on 1 month follow-up. Doctors should be aware of the diagnosis and treatment of this complication associated with the application of hair dye as the popularity of this procedure increases.

Treatment of Mooren's ulcer coexisting with a pterygium using an intrastromal lenticule obtained from small-incision lenticule extraction: case report and literature review.

The coexistence of Mooren's ulcer and a pterygium is an extremely rare ocular condition that has been infrequently reported in the literature to date. We herein present the first case of treatment of Mooren's ulcer coexisting with a pterygium using a lenticule obtained by myopic small-incision lenticule extraction (SMILE). A 61-year-old woman presented with a 3-month history of recurrent ocular pain and red eye caused by Mooren's ulcer coexisting with a pterygium. She received topical immunosuppressive and anti-infection treatments for almost 3 months. However, her ocular symptoms and signs did not substantially improve. Therefore, we performed lamellar keratoplasty with a corneal lenticule obtained by SMILE, followed by pterygium excision combined with conjunctival autografting. The patient recovered well with no complications or recurrence 1 year postoperatively. Our success suggests that combined surgery may be an effective management for coexistence of Mooren's ulcer and a pterygium if conservative treatments fail. A corneal lenticule obtained by SMILE can be used as the lamellar keratoplasty graft in such patients.

ABSTRACT Introduction: Spontaneous evolution or poorly treated cases of corneal ulcer carry the risk of extension of the infection, with severe visual impairment and damage to the structural integrity of the eye. Objective: To describe the clinical-epidemiological characteristics of patients with severe bacterial corneal ulcer treated with local ozone therapy as an adjunct to the standard protocol treatment. Method: An observational, descriptive and cross-sectional study was carried out on 48 patients admitted to the Ophthalmology service of the Hospital General Docente "Dr. Juan Bruno Zayas Alfonso", from Santiago de Cuba, in the period from January 2017 to December 2019. The study variables were: age, gender, predisposing factors, microorganisms, signs of clinical improvement, treatment results and complications. Chi-square test was used for statistical validation. Results: The average age of the patients was 54.1 years; 62.5% of them were men. Ocular trauma (63.3%) predominated in males, and ocular diseases (44.4%) in females. The improvement of the signs was more common after 14 days. Satisfactory results were achieved in 100% of patients with gram-positive organisms. 10.4% presented corneal perforation. Conclusions: Ozone therapy is valid as a treatment for severe corneal ulcer of bacterial etiology, and responds to the search for alternatives for patients with resistance to the antibacterial treatments that are offered in the basic health system.

Streptococcus pneumoniae endophthalmitis: clinical settings, antibiotic susceptibility, and visual outcomes.

Streptococcus pneumoniae endophthalmitis is clinically more severe, more difficult to treat, and carry a higher risk of vision loss, evisceration, or enucleation. This study is to investigate the clinical settings, antibiotic susceptibility, and visual outcomes of S. pneumoniae endophthalmitis at a tertiary referral center in Taiwan. S. pneumoniae endophthalmitis was diagnosed in 38 eyes of 38 patients. The main clinical features were postcataract endophthalmitis (n = 13, 34%) and endophthalmitis associated with corneal ulcer (n = 12, 32%), trauma (n = 6, 16%), endogenous etiology (n = 4, 11%), trabeculectomy (n = 2, 5%), and pterygium excision-related scleral ulcer (n = 1, 3%). Presenting visual acuity ranged from counting fingers to no light perception. Pars plana vitrectomy with intravitreal antibiotics was performed in 17 eyes (39%) in primary or secondary treatments. S. pneumoniae isolates were susceptible to vancomycin (38/38, 100%), penicillin (37/38, 97%), ceftriaxone (37/38, 97%), cefuroxime (12/15, 80%), levofloxacin (13/15 ,87%), and moxifloxacin (15/17, 88%). Final visual acuity was better than 20/400 in 3 of 38 eyes (8%), 5/200 to hand motions in 3 eyes (8%), and light perception to no light perception in 32 eyes (84%). Ten eyes (26%) underwent evisceration or enucleation. Although S. pneumoniae isolates were susceptible to vancomycin, S. pneumoniae endophthalmitis had a very poor visual prognosis.

Erythema elevatum et diutinum as a systemic disease.

Erythema elevatum et diutinum (EED) is a rare, chronic dermatosis. It has been associated with extracutaneous findings, including arthralgias, scleritis, panuveitis, peripheral ulcerative keratitis, oral and penile ulcers, and neuropathy. Additionally, EED is connected with various systemic diseases, including HIV, IgA paraproteinemia, myelomas, neutrophilic dermatoses, and inflammatory bowel diseases. The presence of such extracutaneous manifestations in EED patients suggests that EED may be a multiorgan entity. Extracutaneous manifestations in EED may involve deposition of circulating immune complexes; thus, patients with EED should be evaluated for systemic manifestations to ensure targeted management.

Clinical course and risk factors of recurrent corneal erosion: Observational study.

Recurrent corneal erosion (RCE) is a common disorder causing ocular pain, tearing, photophobia, and visual impairments. Various factors such as ocular trauma, ocular surgery, corneal dystrophy, contact lens wear, and diabetes mellitus (DM) can cause RCE. The purpose of this study was to determine the causative factors and clinical course of RCE.We retrospectively examined 21 eyes of 21 patients with RCE and investigated the patients' background, type of treatments, and clinical course after the treatments. All patients were treated with eye drops, ocular lubrication, or contact lens bandage for the RCE.Among the 21 patients with RCE, 9 were caused by trauma (Trauma group), 8 by DM (DM group), 1 by bacterial corneal ulcer, 1 by lagophthalmus and bacterial corneal ulcer, 1 by bandkeratopathy, and 1 by eyelid tumor (one eye). The mean age of the patients was 57.8 years with a range 34-91 years. The mean duration from the trauma to the onset of RCE was 5.2 ±â€Š5.0 months (mean ±â€ŠSD). The time required for a complete recovery of RCE was longer in the DM group (10.3 ±â€Š3.1 weeks) than in the Trauma group (2.7 ±â€Š1.1 weeks, P < .01). The presence of DM was significantly associated with the recovery duration of RCE (r = 0.72; P < .01). Multivariate analyses showed that the recovery duration of RCE was associated with the presence of DM (odds ratio = 139.8, P = .04). On the other hand, the type of treatments had no effect on the recovery duration of RCE.These findings suggest that trauma and DM are important causes of RCE. Wound recovery after RCE may be delayed in patients with DM.

A novel herpesvirus associated with chronic superficial keratitis and proliferative conjunctivitis in a great horned owl (Bubo virginianus).

An adult great-horned owl (Bubo virginianus; GHOW) presented with a history of recurrent corneal ulceration of the right eye (OD). Findings included ulcerative superficial keratitis, proliferative conjunctivitis, and iris pigmentary changes. The ulcer was initially nonresponsive to medical therapy, but showed rapid and appropriate healing following diamond burr debridement. Proliferative conjunctivitis markedly improved following topical antiviral therapy with cidofovir 1%, interferon alpha 2B ophthalmic solutions, and oral l-lysine. Histopathologic evaluation of a conjunctival biopsy revealed epithelial features suspicious for viral cytopathic changes and intranuclear structures suspicious for viral inclusions, suggestive of a possible viral-induced papillomatous conjunctivitis. A novel alphaherpesvirus, referred to as Strigid Herpesvirus 1 (StrHV1), was identified using PCR and gene sequencing. This case represents a new clinical manifestation of a previously unreported herpesvirus in the GHOW. Identification of the herpes virus was critical to administration of appropriate therapy and resolution of the conjunctivitis, and corneal epithelial debridement promoted resolution of the chronic corneal epithelial defect.

Stenciling-Based "Prick and Print" Technique for Harvesting Shaped Corneal Grafts for Management of Peripheral Corneal Perforations.

PURPOSE: To evaluate a new surgical technique ("prick and print") for harvesting shaped donor corneal grafts in cases with perforated peripheral ulcerative keratitis (PUK). METHODS: We conducted a retrospective case series at a tertiary center. Medical records of 13 patients with perforated PUK, who underwent tectonic eccentric keratoplasty using the stenciling-based prick and print technique during the past 1 year, were reviewed. All patients (15 eyes of 13 patients) received grafts of varying sizes and shapes (14 crescentic and 1 biconvex). Factors evaluated were tectonic integrity, graft apposition, and complications, if any. Surgical success was defined as maintenance of corneal integrity and healing of PUK. RESULTS: Mean age of patients was 40.6 ± 19.4 years. Mean follow-up was 10 months. We achieved surgical success in 80% (12/15 eyes) of cases. Two eyes had graft infection, and regrafting (large circular graft) was performed for both. One eye developed new-site PUK, which was managed medically, and the graft remained viable tectonically. After surgery, 9 eyes achieved a best-corrected visual acuity of logarithm of the minimum angle of resolution +0.3 or better. No cases had graft rejection or peripheral anterior synechiae by final follow-up. CONCLUSIONS: The stenciling-based prick and print technique for making shaped donor corneal grafts may offer a simple, easy-to-learn surgical technique that can be used to make any shape or pattern of donor corneal grafts without involving the optical center, even in extensive peripheral corneal lesions.

Predominó la etiología bacteriana y la úlcera central profunda. Dentro de los factores de riesgo ocular los resultados señalan como principal factor el trauma ocular (56,5%), el uso de antibiótico tópico y sistémico por tiempo prolongado. Todos los pacientes recibieron tratamiento tópico con colirio fortificado, entre las complicaciones se presentó el descematocele en un 30,4 % de los casos. Conclusiones: La fundamentación teórica de los colirios fortificados y los resultados obtenidos en esta investigación, demuestran la eficacia del uso en la úlcera grave de la córnea (AU).

Introduction: the corneal ulcer is a suppurated inflammation that may have several etiologies and clinical manifestations. It is a potentially serious entity endangering the patient´s vision and could cause blindness. Objective: to describe the theoretical fundaments supporting the use of fortified eye drops in the treatment of severe corneal ulcer; to identify the clinic-epidemiological variables of the studied group; to arrive to the clinical and etiological diagnosis of the corneal ulcer and to assess disease evolution and complications incidence. Materials and methods: a descriptive, cross-sectional research was carried out in the period from January 2015 to January 2016. The patients diagnosed with severe corneal ulcer who were admitted in the hospital were taken into consideration. The sample was formed by 23 patients diagnosed with severe corneal ulcer. Results: among the 23 patients diagnosed with severe corneal ulcer predominated male sex and people aged more than 60 years. The bacterial etiology and deep central ulcer predominated. As for the ocular risk factors, the results show ocular trauma as main factor (56.5 %) and the use of systemic and topical antibiotic for a long time. All the patients were topically treated with fortified eye drops. Descematocele was found among the complications in 30.4 % of the cases. Conclusions: the theoretical fundament of the fortified eye drops and the results obtained in this research show the efficacy of their use in the severe corneal ulcer (AU).

Unusual ulcerative keratitis caused by Prototheca wickerhamii in a diabetic patient.

The purpose of the study was to report a case of ulcerative keratitis caused by an unusual algae Prototheca wickerhamii in a diabetic patient. This study design was a case report. A 46-year-old male, who was a known diabetic for 3 years, had an injury to the left cornea with the sparks of fire from wielding at work that developed into an ulcerative keratitis over a period of next 3 months as the patient was not on any medication. Corneal scraping culture report and Vitek 2 system investigation result confirmed it to be a P. wickerhamii infection. The patient was started on intensive topical 1% voriconazole and 5% natamycin for 1 month and with no improvement subsequently underwent penetrating keratoplasty. No recurrence of infection postoperatively was noted. This opportunistic algae rarely known to cause human eye infections is so far reported in either patients with severe systemic immunosuppression causing posterior segment eye involvement or as postcorneal surgery infections. We report an ulcerative keratitis by P. wickerhamii in a diabetic patient post corneal trauma with no prior ocular surgery.

Peripheral Ulcerative Keratitis Associated with Granulomatosis with Polyangiitis Emerging Despite Cyclophosphamide, Successfully Treated with Rituximab.

A 67-year-old Japanese man was diagnosed with granulomatosis with polyangiitis based on the presence of right maxillary sinusitis, proteinase 3 antineutrophil cytoplasmic antibody positivity, and right scleritis. A conjunctival biopsy specimen showed neutrophil-predominant infiltration around the vessels without granuloma. Because there was a risk of blindness, pulsed methylprednisolone and intravenous cyclophosphamide pulse therapy (IVCY) were started. However, it was ineffective, and peripheral ulcerative keratitis newly emerged. We promptly switched the treatment from IVCY to rituximab, and ophthalmologists performed amniotic membrane transplantation, which avoided blindness. The close and effective working relationship between physicians and ophthalmologists improved our patient's ocular prognosis.

Corneal perforation from peripheral ulcerative keratopathy in patients with rheumatoid arthritis: epidemiological findings of the British Ophthalmological Surveillance Unit.

BACKGROUND/AIMS: This study quantifies the threat to vision and the survival in patients presenting with peripheral ulcerative keratopathy (PUK) corneal perforation associated with rheumatoid arthritis (RA) in the UK. METHODS: New cases of corneal perforation from PUK in patients with RA were prospectively collected from the UK via the British Ophthalmological Surveillance Unit from July 2012 to June 2014. An initial questionnaire collected data on presentation and the first 2 weeks' management, and a follow-up questionnaire collected 1-year data on ocular morbidity and mortality. RESULTS: 30 eyes of 28 patients were identified over 2 years, estimating a UK incidence of 0.234/million/year. 20/27 (74%) were female, with a median age of 68 years (range 41-84). The most common initial management was cyanoacrylate glue with a bandage contact lens, oral steroids, topical and oral antibiotics, and lubricants. Long-term management included corneal grafting in 12/20 (60%) eyes of patients living at 1 year. The 1-year all-cause mortality was 6/25 (24%), which increased to 1/2 (50%) if both eyes had perforated. In the remaining patients alive at 1-year follow-up, there was a 13/20 (65%) poor visual outcome of less than or equal to counting fingers. 8/25 (40%) patients had bilateral PUK, with 2/25 (8%) having bilateral perforation. 5/19 (26%) patients alive at 1-year follow-up were eligible for sight impairment registration. CONCLUSION: This study highlights the serious ocular morbidity and high mortality associated with corneal perforation from PUK in patients with RA despite treatment. The mortality doubled if both eyes perforated, which should serve as a harbinger of impending serious medical problems.

Impacto do grau de uveíte em diferentes tipos de úlceras de córneas em cães submetidos ao enxerto pediculado de conjuntiva bulbar - 34 casos / Impact of uveitis score on different types of corneal ulcers in dogs subjected to the bulbar conjunctival pedicle graft - 34 cases

O presente trabalho objetivou avaliar os resultados de 34 olhos submetidos ao enxerto conjuntival pediculado (ECP) em ceratites ulcerativas profundas (n=5), em ceratites ulcerativas com colagenólise (n=2), descemetocele (n=7), perfuração corneal (n=15) e prolapso de íris (n=5). Os impactos do grau de uveíte e da integridade da córnea foram correlacionados com presença e ausência de visão por tabelas de contingência. Raças braquicefálicas foram acometidas em 91,11% dos casos. O número de córneas consideradas perfuradas [20/34 (58,82%)] foi maior que o de córneas íntegras [14/34 (41,17%)]. Ao 50º dia de pós-operatório, o número de olhos visuais que apresentavam córneas íntegras previamente às cirurgias (n=13) não diferiu significativamente dos olhos com córneas perfuradas (n=12) (P=0,05). Avaliações relativas ao grau de uveíte, revelaram que a metade dos casos foi considerada severa [17/34 (50%)] e na outra metade as uveítes foram consideradas discretas. Dos 17 casos que apresentaram uveíte severa, oito recuperaram a visão. Já nos 17 olhos onde a uveíte foi considerada leve, 15 mantiveram a visão ao final do período de avaliação. Apesar de a integridade da córnea não se correlacionar com a severidade da uveíte (P=0,48), constatou-se que o número de olhos visuais com uveíte discreta foi significativamente maior que os olhos com uveíte severa (P=0,006). Neste estudo, a taxa geral de sucesso visual após ECP foi de 73,52% e a integridade da córnea não exerceu impacto significativo sobre a manutenção da visão. Todavia, olhos acometidos por uveítes severas apresentaram menor chance de recuperar a visão.(AU)

The present study aimed to evaluate the results of 34 eyes of dogs presenting deep corneal ulcer (n=5), colagenolytic corneal ulcer (n=2), descemetocele (n=7), corneal perforation (n=15), and iris prolapse (n=5) that were corrected by the bulbar conjuntival pedicle graft (CPG). The uveitis score and the corneal integrity were correlated with the presence or absence of vision by contingency tables. Brachycephalic breeds accounted for 91.11% of all cases. The number of perforated corneas [20/34 (58.82%)] were higher than the non-perforated ones [14/34 (41.17%)]. At post-operative day 50, the number of visual eyes with non-perforated corneas before surgery (n=13) did not differ significantly from the eyes with perforated corneas (n=12) (P = 0.05). In half of the cases, uveitis score was considered severe [17/34 (50%)], and in the other half, mild. Eight out of 17 eyes classified with severe uveitis regained vision. In 17 eyes where uveitis score was considered mild, 16 regained vision at the end of the study. Although corneal integrity was non-correlated with the uveitis score (P = 0.48), the number of visual eyes scored with mild uveitis were significantly larger than the eyes with severe uveitis (P = 0.006). In this study, the overall success visual rate after CPG was 73,52% % and the corneal integrity did not play an important role regarding maintenance of vision. However, eyes presenting severe uveitis score had less chance to regain vision.(AU)

Clinical course and outcomes in patients with Mooren ulcer who had cataract surgery.

PURPOSE: To report outcomes of cataract surgery in patients with Mooren ulcer. SETTING: L.V. Prasad Eye Institute, Hyderabad, India. DESIGN: Retrospective case series. METHODS: The medical records of patients with Mooren ulcer who had cataract surgery between 2000 and 2015 were assessed. The main outcome measures were the role of preoperative immunosuppression and disease inactivity, cataract surgery safety, visual outcomes, and postoperative ulcer recurrence. RESULTS: Of 22 patients (26 eyes), the mean corneal ulceration was 6.8 clock hours ± 2.9 (SD). Corticosteroids were the most commonly used (84.6% of the 26 eyes) preoperative immunosuppression agents and 38.5% of the 26 eyes were under maintenance immunosuppression. The median disease inactivity before surgery was 7 months. Cataract surgery was extracapsular in 10 patients, small incision in 3 patients, and phacoemulsification in 13 patients. Twenty-two eyes had scleral incisions. The median follow-up was 6 months (interquartile range, 10 months). The median corrected distance visual acuity (CDVA) improved from 1.48 logarithm of minimum angle of resolution (logMAR) before surgery to 0.30 and 0.35 logMAR at 1 month and at the last follow-up after surgery, respectively (P ≤ .0001). Mooren ulcer recurred in 5 eyes between 3 months and 7 years after surgery. No disease activity was seen in the immediate postoperative period. No significant risk factors for disease recurrence were noted. CONCLUSIONS: With adequate immunosuppression, cataract surgery in eyes with Mooren ulcer was safe and CDVA improved significantly with no disease reactivation immediately after surgery. No proven role of maintenance immunosuppression was observed. The type of cataract surgery had no influence on ulcer reactivation. Patients with a disease-free interval of 6 months or more before surgery and those who had scleral incisions had favorable outcomes.

Acquired anterior staphyloma after corneal ulcer associated with the use of crack.

We describe an unusual case of acquired anterior staphyloma in a patient addicted to crack cocaine. At the beginning of his crack cocaine abuse, he noticed redness and irritation of his eyes. Over the next 4 months, the patient also noticed the onset of decreasing visual acuity in his right eye (OD). Initially, his visual acuity was light perception in OD, and slit-lamp examination revealed a corneal infiltrate with a peripheral perforation and an iris prolapse. The patient was hospitalized to ensure compliance with the prescribed treatment and was advised to undergo therapeutic keratoplasty; however, the patient left the hospital against medical advice and was lost to follow-up for the next 6 months. He returned with complaints of photophobia and the inability to close his right eyelids. At this time, his cornea had developed an anterior staphyloma and required a sclerokeratoplasty. Following surgery, the patient was again lost to follow-up.
