RESUMO
Purpose@#To report a case of unilateral incipient syphilitic papillitis.Case summary: A 53-year-old female visited for a routine ocular examination. Best-corrected visual acuities were 20/20 in both eyes and there was no abnormality in the anterior segment, pupillary response, ocular motility examination, color vision test, and there were no inflammatory cells in the anterior chamber and vitreous cavity of both eyes. However, optic disc edema and corresponding retinal nerve fiber layer (RNFL) thickening in her left eye were observed in a fundoscopic examination and by optical coherence tomography. In orbital magnetic resonance imaging, there was no abnormal enhancement of the optic nerve or optic nerve sheath in both eyes. Serological tests were positive for fluorescent treponemal antibody absorbance (FTA-ABS) immunoglobulin M (IgM) and IgG, the treponema pallidum hemagglutination test, venereal disease research laboratory (VDRL) testing, and a rapid plasma reagin test, but there was no abnormal finding in cerebrospinal fluid analyses including the VDRL and FTA-ABS tests. With the diagnosis of unilateral incipient syphilitic papillitis in her left eye, she was treated with intravenous penicillin for 14 days and high dose systemic steroids for 3 days with complete resolution of the optic disc edema and RNFL thickening. @*Conclusions@#Syphilis can present as a unilateral incipient papillitis. Therefore, in case with unilateral papillitis, serological test for syphilis, appropriate antibiotics and steroid treatment should be considered.
RESUMO
PURPOSE: To report a case of non-glaucomatous retinal nerve fiber layer (RNFL) defect associated with paravascular inner retinal defect (PIRD) in a patient with idiopathic epiretinal membrane (ERM).CASE SUMMARY: A 70-year-old male who was diagnosed with ERM in his right eye and pseudoexfoliative glaucoma in his left eye visited our clinic. His intraocular pressure was 14 mmHg in both eyes while using topical hypotensive medications in both eyes. His right eye showed no glaucomatous change of the optic disc head, and also no glaucomatous visual field defect on standard automated perimetry. Red-free fundus photography and swept-source optical coherence tomography showed an ERM and wedge-shaped RNFL defect starting from the PIRD, not the optic disc head. He was diagnosed with non-glaucomatous RNFL defect in the right eye and was told to stop using topical hypotensive medication for the right eye. After 2 years of discontinuing the medication, the IOP was within the normal range, the RNFL defect showed no progression, and the visual field remained stationary.CONCLUSIONS: A non-glaucomatous RNFL defect can develop in association with PIRD in patients with idiopathic ERM. Examinations for PIRD as well as evaluation of the optic disc head are therefore necessary in patients with ERM and RNFL defect.
