While invasive aspergillosis occurs typically in severely immunocompromised patients, cases of surgical site infections have been reported in immunocompetent individuals. The purpose is to report an eye with post-operative Aspergillus endophthalmitis, which achieved a good visual outcome following early and aggressive treatment. A young patient, known case of allergic bronchopulmonary aspergillosis presented to us with post-cataract surgery endophthalmitis. He was treated with pars plana vitrectomy and intravitreal voriconazole and systemic itraconazole. The patient regained a vision of 20/30 with follow up of 2 years.

While invasive aspergillosis occurs typically in severely immunocompromised patients, cases of surgical site infections have been reported in immunocompetent individuals. It was unique case of aspergillous endophthalmitis associated with allergic broncho-pulmonary aspergillosis. No such case has been reported till date. Our case indicates that early pars plana vitrectomy and aggressive treatment with intravitreals and systemic anti-fungal drugs can lead to better visual outcome.
| Case Report|| |
A 25-year-old male was referred to us with a 10-day history of decreased vision in the left eye after cataract surgery elsewhere. There was no history of diabetes or ocular trauma.
Initial examination revealed a visual acuity of counting finger close to face in left eye and 20/30 in right eye. The anterior segment in right eye revealed aphakia after being operated for steroid-induced cataract elsewhere and in left eye showed 3 mm hypopyon and intraocular lens. Cornea was clear. Vitreous cavity was hazy with no view of the retina in left eye. Ultrasonography showed multiple moderate to high reflective echoes with attached retina.
He was a known case of bronchial asthma and was on irregular treatment of steroids. He was diagnosed to be a case of allergic bronchopulmonary aspergillosis at our institute on the basis of diagnostic criteria for diagnosing ABPA.  His total white blood cell count was 19000/cmm. Differential leukocyte count revealed raised eosinophil count. Serum Ig E levels were 145 IU/ml. 3 ESR was 58 mm/hr, and C-reactive protein was 1 mg/L. Wheal-and-flare skin reaction to Aspergillus antigen was positive. Sputum for acid-fast bacilli was negative. Serology for HIV and VDRL was negative. Chest X-ray revealed wedge-shaped pleural-based densities.
Diagnostic and therapeutic pars plana vitrectomy was done on the second day of presentation. Vitreous aspirate showed moderate number of neutrophils, branching septate hyphae and no bacteria on Gram stain [Figure 1]. KOH mount revealed brancing septate hyphae. Intravitreal voriconazole 50 microgram/0.1 ml was given. The culture for bacteria was negative, but Sabouraud's agar grew A. flavus.
He was put on topical voriconazole (10 mg/ml) drops one-hourly, and oral Itraconazole 200 mg twice-a-day was given for 6 wks. Oral prednisolone 1 mg/kg/bodyweight and topical prednisolone 1% were started in tapering doses. Two weeks post-vitrectomy BCVA in left eye was 20/50, anterior segment showed no activity [Figure 2]. Retina was attached. One-month postoperative visual acuity improved to 20/30 in left eye. Fundus examination showed posterior vitreous detachment and a horseshoe tear in superonasal quadrant. Barrage laser was done for the same. After 1 month, his vision dropped to 20/70 and fundus showed a partial rhegmatogenous retinal detachment. He underwent revitrectomy with Belt Buckle with 360 degree Endolaser with silicone oil insertion. One-week post-operative showed attached retina [Figure 3]. Two months post-surgery vision improved to 20/30. He was followed every month for 1 year, during which no complications developed. After Silicone oil removal, his BCVA is 20/30.
| Discussion|| |
Allergic bronchopulmonary aspergillosis is a hypersensitivity reaction to A. fumigatus that occurs almost exclusively in patients with asthma or, less commonly, cystic fibrosis. Symptoms and signs are those of asthma with the addition of productive cough and, occasionally, fever and anorexia. Diagnosis is suspected based on history and imaging tests and confirmed by Aspergillus skin testing and measurement of IgE levels, circulating precipitins, and A. fumigatus-specific antibodies. Treatment is with corticosteroids and, in patients with refractory disease, itraconazole.
Endogenous Aspergillus endophthalmitis is reported in immunocompromised individuals. ,, Exogenous Aspergillus endophthalmitis is reported following cataract surgery, keratoplasty, and eye trauma.
A review of literature revealed only 5 other cases of endogenous Aspergillosis endophthalmitis in immunocompetent patients. ,, Recognized risk factors include a history of immunocompromise, malignancy, organ transplantation, long-term corticosteroid use, drug abuse, ocular surgery, trauma, endocarditis, and chronic obstructive airways disease. ,, As in our patient, 3 of the reported immunocompetent cases had been treated with corticosteroids for their symptoms prior to the diagnosis being made. , The portal of entry in our case was probably the lungs. It would be reasonable to assume that the administration of steroids in the absence of anti-fungal agent may have worsened the condition in our case.
There are only 2 patients reported in the literature with endogenous A. flavus who recovered useful vision, from a total of 6 patients, with endogenous Aspergillous spp. who received a final visual acuity of 20/200 or better. Both patients underwent an early pars plana vitrectomy with intravitreal and systemic amphotericin B and recovered vision to 20/70. During the vitrectomy, it is preferred to avoid a very posterior vitrectomy as well as peeling of exudates and membranes over the retina to avoid iatrogenic retinal tears. These can occur in endophthalmitis as the retina tends to be edematous, necrotic, and friable.  Poor visual outcomes were correlated with macular lesions of Aspergillous. ,
Voriconazole is a second generation synthetic derivative of fluconazole.  Voriconazole is an effective agent for treatment of fungal endophthalmitis; it has a broad spectrum of activity. Intravitreal dose of Voriconazole up to 100 microgram/ml is considered safe for the retina.  Voriconazole is superior or at least similar to amphotericin B against common and rare yeast and mould infections. It is suggested that voriconazole should be considered as a first-line intravitreal agent for treatment of fungal endophthalmitis. 
Itraconazole exhibits a favorably low MIC for many species of Aspergillous, and in selected reports, it has shown a favorable response for the treatment of invasive aspergillosis. The vitreous penetration of itraconazole is better than amphotericin but remains only a fraction of the serum level. , It is suggested that oral fluconazole or itraconazole should be included in the regime.
| Conclusion|| |
Endogenous fungal endophthalmitis should be considered in the differential diagnosis of progressive intraocular inflammation of unknown cause in persons predisposed to systemic fungal infection. When the infection is isolated to the choroid and retina, systemic treatment alone may be curative. When there is vitreous involvement, a vitrectomy and intravitreal injection of voriconazole should be considered. Fungal endophthalmitis following early and aggressive treatment results in good visual outcome.
