Fulltext Bartonella henselae Neuroretinitis: A Rare Coinfection in POEMS Syndrome

Ab Kahar MEPI, Muhammed J, Hitam WHW, Husin A

Turk J Ophthalmol, 2020 12 29;50(6):371-376.
PMID: 33389938 DOI: 10.4274/tjo.galenos.2020.83873

Bartonella henselae is a recognized cause of neuroretinitis in cat scratch disease. Meanwhile, polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, skin changes (POEMS) syndrome with Castleman disease (evidence of lymph node hyperplasia), is a chronic debilitating condition that predisposes to various superimposed infections. B. henselae neuroretinitis implicated in POEMS syndrome has not been reported previously. A 34-year-old asymptomatic man was referred for an eye assessment. Examination showed visual acuity of 6/18 in the right eye and 6/24 in the left eye. On fundus examination, both eyes exhibited typical features of neuroretinitis (optic disc swelling and incomplete macular star). There was otherwise no vitritis or chorioretinitis. Serology for B. henselae revealed high immunoglobulin M (IgM) titer (1:96) indicative of acute disease, and positive immunoglobulin G (IgG) (1:156). He was treated with oral azithromycin for 6 weeks and a short course of oral prednisolone. Subsequently, the visual acuity in both eyes improved with resolution of macular star. However, both optic discs remained swollen.

Fulltext Microbial keratitis: aetiological diagnosis and clinical features in patients admitted to Hospital Universiti Sains Malaysia

Norina TJ, Raihan S, Bakiah S, Ezanee M, Liza-Sharmini AT, Wan Hazzabah WH

Singapore Med J, 2008 Jan;49(1):67-71.
PMID: 18204773

Corneal ulceration remains one of the major causes of blindness in developing countries, including Malaysia. Our objective is to determine the epidemiological characteristics, clinical features, risk factors and the aetiology of microbial keratitis in patients admitted to Hospital Universiti Sains Malaysia (HUSM).

Assessment of polymerase chain reaction in the detection of pseudomonas aeruginosa in contact lens-induced severe infectious keratitis

Subrayan V, Peyman M, Lek Yap S, Mohamed Ali NA, Devi S

Eye Contact Lens, 2010 Jul;36(4):201-3.
PMID: 20531205 DOI: 10.1097/ICL.0b013e3181e3efa3

PURPOSE: The aim of this study is to evaluate the role of real-time polymerase chain reaction (PCR) and conventional bacterial culture methods in the detection of Pseudomonas aeruginosa in contact lens-induced severe, partially treated corneal ulcers referred to a tertiary center.
METHODS: The study duration was 6 months. All patients with contact lens-related corneal ulcer, requiring admission during the study period were recruited. Samples from corneal scrapings were simultaneously sent at the time of admission for PCR and culture testing. An in-house real-time PCR was developed to detect the P. aeruginosa lasA gene. The results of PCR and culture were compared using McNemar's chi2 test.
RESULTS: Ten patients were recruited. The mean age was 33 years (20-45 years). All the patients had contact lens-related keratitis (>4 mm) of which eight (80%) were found positive for P. aeruginosa by PCR or culture. There was no significant difference between PCR and culture in detecting P. aeruginosa (P<0.05).
CONCLUSIONS: PCR is, at least, as good as conventional cultures in detecting P. aeruginosa. It is a rapid assay as compared with culture, and early detection enables prompt treatment thus reducing the destructive effect of the organism on the cornea.

Hemorrhagic Descemet Membrane Detachment Following Syphilitic Interstitial Keratitis

Höllhumer R, Zairani Mz A, Watson S

Cornea, 2016 Sep;35(9):1255-6.
PMID: 27227396 DOI: 10.1097/ICO.0000000000000889

PURPOSE: Syphilitic interstitial keratitis is a stromal inflammatory disease with characteristic secondary vascularization. This case illustrates a late complication of hemorrhagic Descemet membrane detachment.
METHODS: Case report.
RESULTS: The patient presented with painless sudden visual loss and progressive shallowing of the anterior chamber caused by hemorrhagic Descemet membrane detachment. She had corneal neovascularization and a positive syphilis serology. Owing to the risk of pupil block glaucoma, the patient had surgical drainage of the blood via an ab externo approach.
CONCLUSIONS: This case illustrates a previously unreported complication of syphilitic interstitial keratitis. The patient recovered good visual acuity and had residual pigment deposits in the pre-Descemet interface.

Pyogenic Granuloma Formation Following Ahmed Valve Glaucoma Implant

Chendran P, Seng Fai T, Wan Abdul Halim WH, Md Din N

J Glaucoma, 2019 10;28(10):e162-e164.
PMID: 31368915 DOI: 10.1097/IJG.0000000000001334

Ocular pyogenic granuloma is a benign tumor seen after ocular insult secondary to ocular surgeries, trauma or infection. Although benign, intervention is sometimes necessary. Previous authors have reported pyogenic granuloma formation following oculoplastic surgeries. We report a pyogenic granuloma after an Ahmed glaucoma valve implantation. A 65-year-old gentleman presented with right eye redness associated with pain and swelling ~2 months after Ahmed glaucoma valve implantation. Examination found a sessile growth on the tube extruding puss with signs of endophthalmitis. The glaucoma drainage device was explanted and culture results grew Staphylococcus aureus. This article discusses the formation of pyogenic granuloma on a glaucoma drainage device and its management.
