ABSTRACT This study aims to report the case of a patient with Multiple Sclerosis (MS) and investigate the relationship between hypovitaminosis C and the development of the disease, as well as evaluate the impact of vitamin C supplementation on controlling clinical symptoms. A 21-year-old male patient diagnosed with MS, presenting visual complaints and a relevant family history. The investigation included clinical, laboratory, and imaging exams, identifying hypovitaminosis C. The treatment consisted of prednisone administration and vitamin C supplementation. Vitamin C […]

ABSTRACT Case report of a 14-year-old male presented with acute painless vision loss and left optic disc swelling. Extensive diagnostic investigations, including magnetic resonance imaging and serum MOG antibody testing, were conducted. Magnetic resonance imaging showed an extensive T2 hyperintense signal in the anterior portion of the left optic nerve without involving chiasm or retrochiasmatic areas. The management strategy involved intravenous methylprednisolone followed by azathioprine, resulting in complete vision recovery. This case highlights the importance of considering MOG antibody-associated optic […]

ABSTRACT Sickle cell disease is the most common hemoglobinopathy, and the perioperative period can be an exacerbation of the disease. The aim of this report is to describe the case of a patient with Sickle Cell Disease who underwent surgery to correct his strabismus and developed Acute Thoracic Syndrome, the most feared complication in patients with this disease. The adversities of this disease result from the sickling process of red blood cells, which can be triggered by cold, dehydration, and […]

ABSTRACT Stiff-Person syndrome is a rare neuro-immunological condition predominantly affecting proximal and axial limb muscles, with a higher incidence in females aged between the third and seventh decades of life. Ophthalmological involvement is a significant aspect, often correlated with cerebellar dysfunction and various nystagmus forms. A 53 year-old female with a history of hypothyroidism and rectal polypectomy, presenting with diplopia, dizziness, and postural instability, eventually diagnosed with Stiff-Person syndrome. Treatment involves medications like diazepam and gabapentin, besides intravenous immunoglobulin therapy […]

ABSTRACT We present a case of an autosomal dominant optic neuropathy, known as Kjer’s disease. The condition can manifest since childhood, presenting with bilateral symmetric optic atrophy and progressive vision loss. Genetics play a crucial role in the differential diagnosis, due to the association with the OPA-1 gene. In this report, we describe the case of a young vegan woman, initially diagnosed with optic neuropathy due to nutritional deficiency, but with laboratory tests within normal limits and a significant family […]

ABSTRACT We describe a case of Irvine-Gass syndrome and the clinical decompensation of glaucoma after uneventful cataract surgery with resistance to conventional clinical treatment. Drainage tube implantation and intravitreal injection of dexamethasone were performed simultaneously with the resolution of cystoid macular edema and good control of intraocular pressure, which remained consistent after 1 year of follow-up.

ABSTRACT Retinal vasoproliferative tumor is a rare disease associated with several sight-threatening complications. The optimum management of retinal vasoproliferative tumor is unknown and the need of surgery arises when there is diagnostic uncertainty or sight-threatening complications, such as 23G pars plana vitrectomy, perfluorooctane retinal flattening, fluid drainage through a peripheral retinotomy, fluid-air exchange, laser photocoagulation of the retinal vasoproliferative tumor, and 12.5% C3F8 tamponade. We described two cases of retinal vasoproliferative tumor with exudative retinal detachment threatening the macula, treated […]

ABSTRACT Our objective was to report the case of the use of Xen® Gel Stent in the surgical treatment of glaucoma secondary to iridocorneal endothelial syndrome. Female patient, 38 years old, with unilateral glaucoma secondary to iridocorneal endothelial syndrome in the right eye, using maximum tolerable medications (three medications), with medicated intraocular pressure oscillating between 16 and 18 mmHg, demonstrating structural and functional progression, underwent minimally invasive bleb surgery with ab interno closed-conjunctival implantation of a Xen® Gel Stent. The […]
