  • Multimodal Imaging for Differentiating Unilateral Pseudo Optic Disc Swelling(Buried Drusen) From True Optic Disc Swelling

    Feb 7 2024 by Fawwaz F Al Mamoori, MD, Medical Retina Consultant

    27-year-old male, medically free, presented with left unilateral optic disc swelling. BCVA=1.0(OU), color vision, and contrast sensitivity were normal (OU)with no RAPD in the left eye. Swept Source OCT: showed elevated left optic disc with hyporeflective mass (Fig-1 B). Enface OCT: Showed left peripapillary multiple ovoid mass lesions(drusen) (Fig-2 d, Fig3 F). FAF: of the left eye showed superonasal hyper autofluorescent drusenoid lesions)(Fig3 E). Orbital MRI with contrast was requested to exclude any compressive lesions like tumors(menigioma)or inflammatory lesions like granuloma(sarcoid granuloma). orbital MRI result was normal.

    Feb 7 2024 by Fawwaz F Al Mamoori, MD, Medical Retina Consultant

    A 27-year-old male patient, medically free, presented with unilateral left optic disc swelling. BCVA=1.0(OU), color vision, and contrast sensitivity were normal (OU) with no RAPD in the left eye. SS-OCT: showed left optic disc elevation with hyporeflective mass lesion (Fig-1 B). Enface OCT: showed left peripapillary hyperreflective ovoid mass lesions(Fig-2 D, Fig-3 F), FAF: showed left superonasal hyperautofluorescent drusenoid lesions. Orbital MRI with contrast was requested to exclude any optic nerve compressive lesions like (tumors: like mengioma or inflammatory lesions like granuloma (sarcoidosis). the result of orbital MRI was normal.

  • Non invasive multimodal imaging for differentiating unilateral pseudo swelling buried optic disc drusen from true optic disc swelling

    Feb 7 2024 by Fawwaz F Al Mamoori, MD, Medical Retina Consultant

    27-year-old male, medically free, routine fundus examination showed left optic dic swelling, BCVA =1.0(OU), color vision, and contrast sensitivity were normal with no RAPD (OU). SS-OCT of the left optic disc showed a hyporeflective mass. Enface OCT shadogram showed peripapillary ovoid structures (drusen).FAF: showed drusenoid autofluorescence in the superonasal part only. Orbital MRI with contrast was requested to exclude any optic nerve tumor and it was normal.

  • Central Retinal Vein Occlusion

    Dec 22 2018 by FELIPE PEREIRA

    25-year-old male patient with acute and painless vision loss of left eye. The fundus examination demonstrate optic disc swelling, venous tortuosity, diffuse intraretinal hemorrhage and severe macular edema. There is also extensive exudative retinal detachment with lipid deposits in the posterior pole, mainly around the vessels. The systemic work up was negative, including serologies, rheumatologic and hematological markers and cholesterol and triglycerides within normal limits.
