A 60-year-old woman with hypothyroidism, hypertension, and dyslipidemia presented with left-sided strabismus, diplopia, occasional ocular pain, and progressive left-sided proptosis over two years (). Computed tomography (CT) revealed a well-circumscribed, intraorbital mass with ground glass appearance, suggestive of fibro-osseous lesion, unconnected to the adjacent bony structure (). Surgical excision was performed, and histopathological analysis confirmed the diagnosis of fibrous dysplasia (). Fibrous dysplasia is a sporadic, non-hereditary genetic disorder resulting from a mutation in the GNAS1 gene located on chromosome […]

Homem de 69 anos, assintomático, observado em contexto de rotina. A autofluorescência de campo ultra-amplo evidenciou, em ambos os olhos, áreas lineares de hipoautofluorescência ao longo das veias retinianas, delimitadas por bandas de hiperautofluorescência. A imagem A, correspondente ao olho direito, mostra ainda marcas residuais de fotocoagulação panretiniana; a imagem B, do olho esquerdo, apresenta padrão semelhante. Após a exclusão de causas infecciosas e inflamatórias, o conjunto dos achados suportou o diagnóstico de atrofia retinocoroideia paravenosa pigmentada (PPRCA).() Trata-se de […]

A 34-year-old man presented with pain and blurring vision in the right eye for 24 hours. The best-corrected visual acuity was 9/10 in the right eye. Slit-lamp examination of the right eye revealed conjunctival injection, three white granulomatous corneal precipitates (), one of them behind a stromal infiltrated area. A white tyndall effect in the anterior chamber at one cross and ocular hypertension at 50 mmHg were noticed. Gonioscopy shows a 360° open angle with a flat iris insertion root. […]

A 62-year-old healthy man with left-sided headaches for 3 days and redness of the left eye for 24 hours. The best corrected visual acuity of both eyes was 10/10. The left side of the forehead showed incipient vesicles on an erythematous background (). The left eye was slightly injected. Biomicroscopic examination disclosed a large temporal corneal pseudodendrite (). Fluorescein staining under a cobalt-blue filter confirmed this pattern (). Valacyclovir associated with lubricant eyedrops was started. Follow-up examination revealed complete resolution […]

A 35-year-old man presented to the ophthalmology clinic with immediate blurry vision and central scotoma in the right eye after sustaining accidental exposure to a handheld laser pointer (power < 1 mW, wavelength 640 to 660 nm; according to the label on the device) from approximately 5 m away, for a duration that he described as 1 to 2 seconds during a PowerPoint presentation in a conference room. Visual acuity was 20/80 in the right eye and 20/20 in the […]

We present the case of an 80-year-old patient diagnosed with severe pseudoexfoliation syndrome (PEX) in both eyes (OU), who underwent uneventful bilateral phacoemulsification with in-the-bag intraocular lens (IOL) implantation 10 years ago. However, 4 years postoperatively, the patient developed subluxation of the capsular bag-IOL complex in the left eye, attributable to the progressive zonular insufficiency characteristic of PEX. Consequently, the subluxated IOL was removed, and an iris-fixated lens was implanted. During follow-up, 6 years after the initial surgery, a similar […]

CASE REPORT […]

Corneal dystrophy is a hereditary non-inflammatory disorder in which substances accumulate in the cornea. A 32-year-old woman presented for routine ophthalmic examination. The patient has myopia of −6.25 in both eyes with best corrected visual acuity at 8/10 bilaterally. On slit-lamp examination, she was found to have crumb-like and star opacities, grey-white deposits in the anterior corrneal stroma (-). Clear areas were present between the opacities. The peripheral cornea was clear. Her best corrected visual acuity was 8/10 bilaterally. A […]
