82 Possible Causes for Mydriasis, 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.[ncbi.nlm.nih.gov] After 2 months, choroidal swelling had completely resolved, best-corrected visual acuity was 20/50, and intraocular pressure was 11 mm Hg.[ncbi.nlm.nih.gov] In older cases the pupil will dilate and this is called mydriasis.[doi.org]

  • Uveitis

    Tugal–Tutkun, Onal S, Garip A et al., Bilateral acute iris transillumination, Arch Ophthalmol,2011;129(10):1312–9.[touchophthalmology.com] Visual acuity is only decreased in severe cases associated with hypopyon. The signs of anterior uveitis include the following.[symptoma.com] RESULTS: We found intraocular hypertension, cells in the anterior chamber, paralytic mydriasis, iris atrophy with transillumination defects, and variable anterior vitreous[ncbi.nlm.nih.gov]

  • Pseudoexfoliation Syndrome

    Loss of iris pigment and its deposition throughout the anterior segment are refl ected in iris sphincter region transillumination defects, loss of the pupillary ruff, pigment[tmj.ro] Symptoms like a disturbance in the visual acuity or decreased field of vision may manifest in tandem with increased intraocular pressure.[symptoma.com] METHODS: All 674 cataract patients had a comprehensive eye examination, including slitlamp biomicroscopy before and after mydriasis, IOP measurement, and fundus examination[ncbi.nlm.nih.gov]

  • Diabetic Cataract

    iris transillumination has been noted.[ncbi.nlm.nih.gov] In majority of the subjects, best corrected visual acuity (BCVA) gradually improved in each subsequent follow-up visit.[ncbi.nlm.nih.gov] Obtained mydriasis in long-term type 2 diabetic patients. J Ocul Pharmacol Ther. 2011 Dec;27(6):599-602. Epub 2011 Aug 31. 5.[ophthalmologymanagement.com]

  • Ectopia Lentis

    Those patients with simple lens ectopia as well as those with ectopic lenses and pupils had striking transillumination of the iris periphery.[ncbi.nlm.nih.gov] After 2 years, she presented with intermittent ocular pain and decreased visual acuity of the left eye.[synapse.koreamed.org] On slit lamp examination under mydriasis, both eyes revealed ectopia lentis with lens coloboma and stretched zonules.[egms.de]

  • Secondary Glaucoma

    This was evidenced by characteristic transillumination defects in the iris. 3 In 1992, researchers suggested that posterior bowing of the peripheral iris was caused by reverse[reviewofoptometry.com] For one of these three eyes, visual acuity decreased to no light perception.[healio.com] (Top right) Following mydriasis elongated ciliary processes can be seen being pulled into the mass.[clinicalgate.com]

  • Exfoliation Syndrome

    Furthermore, prominent concentric, circular iris transillumination (grade 3) was only observed in XFS.[ncbi.nlm.nih.gov] […] gain. 41 Because the target is not visible to the surgeon transsclerally, there is risk of adjacent tissue damage and resultant inflammation, decreased visual acuity, hypotony[reviewofoptometry.com] METHODS: All 1480 cataract patients had a comprehensive systemic and eye examination, including slit-lamp biomicroscopy before and after mydriasis, IOP measurement, gonioscopy[ncbi.nlm.nih.gov]
