59 Possible Causes for Central Scotoma, Transillumination of the Iris, Visual Acuity Decreased

  • Glaucoma

    The patient had severe bilateral iris transillumination defects with posterior synechiae formation and 3 pigment with rare cell in the anterior chamber.[] After 2 months, choroidal swelling had completely resolved, best-corrected visual acuity was 20/50, and intraocular pressure was 11 mm Hg.[] […] vision was defined as the proportion of participants with a decrease of 2 or more lines on the Snellen chart or one or more categories of visual acuity when unable to read[]

  • Choroid Hemangioma

  • Albinism

    An African girl with OCA-2 showing iris transillumination, yellowish tinted hair and many solar lentigines.[] A 39-year-old man with foveal hypoplasia, nystagmus, and decreased visual acuity was found to have multiple, cutaneous, hypopigmented macules.[] A subset of patients with later onset of disease has been reported to have optic atrophy, thinning of the nerve fiber layer, and a central scotoma.[]

  • Open-Angle Glaucoma

    His visual field (VF) was characterized by bilateral progressive central scotoma.[] POAG but IOP always measured within normal limits) Primary angle closure glaucoma (narrow drainage angle on gonioscopy) Pigment dispersion glaucoma (Krukenberg spindle, iris[] At age 37, her visual acuity was 1/50 with a central scotoma and optic nerve atrophy in each eye.[]

  • Diabetic Cataract

    iris transillumination has been noted.[] In majority of the subjects, best corrected visual acuity (BCVA) gradually improved in each subsequent follow-up visit.[] Complications of focal/grid photocoagulation Impaired central vision. Paracentral scotoma. Choroidal neovascularisation. Epiretinal membrane formation.[]

  • Chediak Higashi Syndrome

    The iris has transillumination defects and the retina is hypopigmented. Patients are photophobic and often have nystagmus.[] Hermansky-Pudlak syndrome, type 2, displays cutaneous albinism, decreased visual acuity, prolonged bleeding, neutropenia and recurrent infections.[] […] manifest as iris transillumination or reduced retinal pigmentation.[]

  • Posterior Uveitis

    Presenting complaints were blurred vision (18), red eye (5), floaters (3), tearing (1), eye pain (1), and central scotoma (1).[] Corneal sensation with careful inspection of the iris for subtle transillumination defects may help identify underlying herpetic disease.[] However, thereafter the visual acuity decreases again. Cataract and elevated IOP are common side effects.[]

  • Retinal Pigmentary Dystrophy

    The disease usually begins at an early age, has a slow progression, and leads to decreased central visual acuity and central scotoma.[] The classic triad of PPDS is the presence of Krukenberg spindles (KS), transillumination iris defects (TID), and trabecular pigmentation. [2], [5], [6], [7], [8] Qing et al[] Therefore, if visual acuity decreases or metamorphopsia (crooked lines and different sized squares on an Amsler Grid) develops in these patients, careful fluorescein or Indocyanine[]
