ABSTRACT Normal-tension glaucoma (NTG) is a glaucomatous optic neuropathy that occurs in the absence of intraocular hypertension, and its pathophysiology is not solely dependent on pressure-related factors. Extrinsic mechanisms, such as autonomic dysfunction and microvascular hemodynamic alterations, have been implicated in its progression, with obstructive sleep apnea (OSA) standing out as an important contributing factor. We report the case of a patient with NTG and severe OSA confirmed by polysomnography, who exhibited progressive structural and functional loss despite controlled intraocular […]

ABSTRACT This case series presents the shamrock sign, a novel aberrometry pattern characterized by trefoil and coma, as a potential diagnostic marker for nuclear cataracts associated with myopic shift. This study highlights its clinical relevance and contribution to early detection and management. The primary diagnosis was nuclear cataracts inducing myopic shift. All patients underwent phacoemulsification with intraocular lens implantation. Postoperatively, all cases showed marked reductions in higher-order aberrations, including spherical aberration and trefoil, with complete resolution of the shamrock sign. […]

ABSTRACT We report a rare case of spontaneous extrusion of a Müller sphere implant three decades after ocular evisceration. A 44-year-old woman, with a history of evisceration of the left eye due to phthisis bulbi from congenital syphilis, presented with extrusion of an orbital implant. Surgical management consisted of reimplantation of a new sphere using a reconstructive technique with scleral shell and biological support. Postoperative recovery was favorable, and progressive prosthetic rehabilitation provided satisfactory functional and cosmetic outcomes. This case […]

ABSTRACT This study was aimed at reporting a case of Valsava Retinopathy (VR) successfully treated with early YAG laser membraniectomy. This is a case report with analysis of medical records, performance, and recording of complementary exams, performing the laser procedure, assessment of immediate visual acuity, 7 and 30 days after the laser procedure. The patient demonstrated full recovery of visual acuity within 1 week. YAG laser membranectomy has proven effective in dispersing bleeding, accelerating visual recovery faster and more accessible […]

ABSTRACT Amyloidosis is characterized by the extracellular deposition of amyloid protein fibrils in tissues, including the conjunctiva, due to their insolubility in proteolytic enzymes. Conjunctival amyloidosis, particularly involving the eyelid conjunctiva, is a rare clinical entity. We report the case of a 60-year-old Caucasian female who presented with a unilateral lesion in the inferior bulbar conjunctiva, extending to the entire inferior tarsal region and fornix. The lesion appeared as an extensive, elevated, pinkish-yellowish nodular mass with poorly defined borders. An […]

ABSTRACT The objective of this study was to report a case of retinitis pigmentosa in a patient with HIV and ocular syphilis, highlighting the complexity of diagnosis and treatment in overlapping systemic and ocular conditions. A descriptive, qualitative analysis of the patient’s clinical evolution was conducted using medical records and patient interviews. A literature review was performed through PubMed® and SciELO. Data collection followed ethical standards, with informed consent obtained. Treatment with antiretroviral therapy and specific antibiotics for syphilis led […]

ABSTRACT Pilomatrixoma is a rare benign neoplasm derived from hair matrix cells, with a preference for the head and neck region, especially in children and adolescents. Its occurrence in adults, particularly in the eyelid, is uncommon and often leads to misdiagnosis. Clinically, it presents as a firm, painless, subcutaneous nodule with progressive growth. Definitive diagnosis is established through histopathological examination, and the standard treatment is complete surgical excision, with low recurrence rates. This article describes a case of eyelid pilomatrixoma […]

ABSTRACT This article is aimed at presenting the clinical features and management of two distinct subtypes of Iridocorneal Endothelial Syndrome (ICE), highlighting the importance of differential diagnosis and individualized treatment. It shows two case reports of female patients with progressive visual loss. Ophthalmologic examination was performed, including biomicroscopy, gonioscopy, and specular microscopy. Treatment was defined according to clinical need. The first patient, diagnosed with Cogan-Reese Syndrome, presented with pigmented nodules on the iris, uveal ectropion, and posterior synechiae, being treated […]
