Sterile endophthalmitis after intravitreal injection of triamcinolone acetonide: case report and literature review.

Objectives: The first purpose is to present the diagnosis and therapeutic approach in a patient with sterile endophthalmitis associated with triamcinolone acetonide injection. The secondary objective is to assess the incidence of this complication and to summarize the risk factors described in the literature. Case presentation: A 76-year-old male patient presented for painless, unilateral, decreased visual acuity, four days after cataract surgery and simultaneously intravitreal triamcinolone acetonide injection for diabetic macular edema in the right eye. The diagnosis of sterile endophthalmitis was made. Eight days after the presentation, the symptoms subsided, the maximum corrected visual acuity reaching that before the procedures. Discussions: The incidence of sterile endophthalmitis varies in the literature between 0% and 23.8%. Visual prognosis is good, although the pathogenesis is not fully understood. Preservatives in injectable solutions have been suggested, however, there are studies in which inflammation was also present with preservative-free products. The particle size of triamcinolone was analyzed, demonstrating an association between smaller particles and an increased frequency of adverse reactions of this type. History of uveitis, posterior capsule rupture following cataract surgery, and Irvine-Gass syndrome are other associations described. Conclusion: The physiopathological mechanism of sterile endophthalmitis is not fully understood. However, the visual prognosis is good, the final vision being dependent on the underlying pathology.

Diagnostic and therapeutic challenges in non-specific orbital inflammation - a case report.

Objective: The aim of this report is to present the diagnostic and therapeutic approach in a case of non-specific orbital inflammation complicated with sight-threatening exposure keratopathy. Case presentation: An 81-year-old female patient presented to our Ophthalmology Department for left, painful, unilateral exophthalmia and decreased vision in the same eye. The clinical examination revealed left proptosis, inferior dystopia, upper lid edema, erythema and moderate retraction, ocular motility restriction, chemosis and corneal epithelial defect. The keratopathy complicated in evolution with hypopyon. The patient received treatment for the exposure keratopathy and, after every specific cause of unilateral exophthalmia was ruled out using imagistic and laboratory examinations, systemic corticosteroid treatment was initiated. Although the response to treatment was prompt, it was incomplete because of the long-standing evolution. Discussions: In this case, the diagnosis was difficult because a malignant breast tumor was encountered and an orbital biopsy was impossible to be performed. The presence of exposure keratopathy complicated with hypopyon imposed the exclusion of an infectious process and delayed the initiation of the corticosteroid therapy. Conclusions: The diagnosis and treatment of this disease represent a challenge given the need to rule out all the local and systemic conditions that may present with exophthalmia.

Phacolytic glaucoma - case report.

We presented a case of a 76-year-old male patient with phacolytic glaucoma and a rather atypical clinical presentation. The sudden onset of intense pain forced the patient to seek medical help and by doing so, further damage of the optic nerve was prevented and a good visual acuity was obtained following cataract surgery.

The effect of intravitreal bevacizumab in a rare case of retinal dystrophy with secondary cystoid macular edema.

The authors presented a clinical case of retinitis punctate albescens in a 26-year-old female patient, with a family history of typical retinitis pigmentosa (father) and bilateral cystoid macular edema treated with anti-VEGF (bevacizumab).

Penetrating keratoplasty: from aid dependence to independence.

The authors present five cases of bilateral corneal disorders, on which they performed penetrating keratoplasty. All five patients were clinically blind and after the surgery on one eye, they gained their visual independence. Visual acuity, intraocular pressure, fundus examination, and ultrasonography were used to evaluate the patients before and after the surgery.
