Trichosporon Endophthalmitis Following Cataract Surgery: A Case Report.

Fungal infections always pose a predicament to management and prognosis. The saprophytic fungus, Trichosporon inkin commonly causes endogenous infection in immunocompromised individuals. We report a case of exogenous T. inkin endophthalmitis successfully treated with voriconazole, pars plana vitrectomy, and removal of the source of infection. A 51-year-old gentleman with suboptimal control of diabetes presented with a right painful red eye for a week after undergoing an uneventful phacoemulsification with a posterior chamber intraocular lens implant more than a month prior. He presented with intense inflammation in the right anterior chamber that did not respond to steroid challenge. Ultrasound B scan showed vitreous opacities with no loculations. The culture of vitreous humor was negative. Systemic investigations were also normal. Despite being given multiple intravitreal antibiotics, his right eye got worse. He then underwent vitrectomy and intraocular lens explantation, in which the culture of the lens grew Trichosporon Inkin. He was subsequently started on the appropriate antifungals (topical, intravitreal, and systemic) based on the minimum inhibitory concentration of the antifungal sensitivity test. The patient eventually showed significant clinical improvement, and intraocular inflammation was subsiding after six months of treatment. His best corrected visual acuity improved to 6/12 with Snellen's visual acuity chart.

Risk factors affecting cataract surgery outcome: The Malaysian cataract surgery registry.

This is a 5 years multicentre database study that recruited subjects from the Malaysian Ministry of Health Cataract Surgery Registry (MOH CSR), aimed to determine risk factors that affect cataract surgery visual outcome and evaluates post-cataract surgery vision. All age-related cataract surgeries with primary intraocular lens (IOL) implantation were included. Cases with secondary cataract, previous ocular surgeries and incomplete data were excluded. A total of 131425 cases were included in the study. Amongst all types of cataract surgery, 92.9% attained post-operative best-corrected visual acuity better than 6/18 and the outcome improved to 97.1% when ocular comorbidities were excluded. Factors with Odds Ratio (OR) >1.5 associated with an impaired visual outcome included: elderly patients of 80 years old and above; systemic disease such as renal failure; ocular co-morbidities; pre-operative vision worse than 6/60; general anaesthesia, retrobulbar anaesthesia or subconjunctival anaesthesia; extracapsular cataract extraction (ECCE), intracapsular cataract extraction (ICCE), anterior chamber intraocular lens (ACIOL) implantation or combined cataract surgery; the presence of intra- and post-operative complications. In conclusion, a good visual outcome was achieved after cataract surgery in most cases. This large multicentre study provides information about risk factors for poor visual outcome post-cataract surgery and may serve as a basis for evidence-based guidelines.

Sinonasal Lymphoma Presenting as Cavernous Sinus Syndrome: Case Report and Review of the Literature.

A 37-year-old man presented with a 1-week history of diplopia. He was under investigation by otorhinolaryngology for left sinonasal malignancy after imaging of the paranasal sinuses had revealed a large homogenous mass in the left nasal cavity. His visual acuity was 6/9 in each eye with no relative afferent pupillary defect. The left pupil, though was mid-dilated and unresponsive to light. He had a left-sided ptosis. Extraocular movements of the left eye were restricted in all directions of gaze and there was with limited abduction, dextroelevation and dextrodepression of the right eye. A trans-nasal biopsy revealed extranodal natural killer/T-cell lymphoma. Further imaging showed a large enhancing nasopharyngeal mass with intracranial extension to the cavernous sinuses and local infiltration together with intracranial abscesses. The patient was started on empirical intravenous antibiotics and supportive treatment. While awaiting institution of lymphoma chemotherapy, he died. The involvement of the cavernous sinus in sinonasal lymphoma represents an advanced stage. This case highlights that lymphoma should be considered in any patient presenting with a cavernous sinus syndrome and sinonasal disease.

Experience in managing glaucoma filtration surgery complications with oral doxycycline: A case series.

PURPOSE: To report the clinical profile and effectiveness of oral doxycycline as a non-invasive treatment for glaucoma filtering surgery complications. METHOD: Prospective case series. RESULTS: Doxycycline is widely used in treating corneal melts, ocular surface diseases, meibomian gland disease, recurrent epithelial cell erosion, rosacea, and keratitis sicca. This prospective case series highlights the successful treatment of five patients with leaking blebs and conjunctiva erosion from glaucoma filtration surgery with the use of oral doxycycline. There was no adverse event reported in our cases. CONCLUSIONS: This study suggests that oral doxycycline may be a feasible non-surgical treatment modality due to its ability to inhibit collagenolysis, restore the Meibomian gland function, thereby stopping breakdown and promote conjunctival tissue healing.

Co-occurrence of acute ophthalmoplegia (without ataxia) and idiopathic intracranial hypertension.

BACKGROUND: Acute ophthalmoparesis without ataxia was designated as 'atypical Miller Fisher syndrome' as it presents with progressive, relatively symmetrical ophthalmoplegia, but without ataxia nor limb weakness, in the presence of anti-GQ1b antibody. Idiopathic intracranial hypertension is characterized by signs of raised intracranial pressure occurring in the absence of cerebral pathology, with normal composition of cerebrospinal fluid and a raised opening pressure of more than 20 cmH2O during lumbar puncture. We aim to report a rare case of acute ophthalmoplegia with co-occurrence of raised intracranial pressure. CASE DESCRIPTION: A 28-year-old gentleman with body mass index of 34.3 was referred to us for management of double vision of 2 weeks duration. His symptom started after a brief episode of upper respiratory tract infection. His best corrected visual acuity was 6/6 OU. He had bilateral sixth nerve palsy worse on the left eye and bilateral hypometric saccade. His deep tendon reflexes were found to be hyporeflexic in all four limbs. No sensory or motor power deficit was detected, and his gait was normal. Plantar reflexes were downwards bilaterally and cerebellar examination was normal. Both optic discs developed hyperaemia and swelling. Magnetic resonance imaging of brain was normal and lumbar puncture revealed an opening pressure of 50 cmH2O. Anti-GQ1b IgG and anti-GT1a IgG antibody were tested positive. CONCLUSION: Acute ophthalmoparesis without ataxia can present with co-occurrence of raised intracranial pressure. It is important to have a full fundoscopic assessment to look for papilloedema in patients presenting with Miller Fisher syndrome or acute ophthalmoparesis without ataxia.

Ocular Surface Disease in Glaucoma: Effect of Polypharmacy and Preservatives.

PURPOSE: To evaluate the prevalence of ocular surface disease (OSD) in glaucoma and nonglaucoma subjects using different clinical tests and to determine the effect of number of antiglaucoma medications and preservatives on OSD. METHODS: This is a cross-sectional, case-comparison study at the Eye Clinic of the University of Malaya Medical Centre, Malaysia, between June 2012 and January 2013. Glaucoma subjects (n = 105) using topical antiglaucoma medications were compared with control subjects (n = 102) who were not on any topical medications. The presence of OSD was assessed using the tear film breakup time (TBUT) test, corneal staining, Schirmer test, and Ocular Surface Disease Index (OSDI) questionnaire grading. RESULTS: The prevalence of OSD varied from 37 to 91% in the glaucoma group, depending on the type of clinical test. More subjects in the glaucoma group had corneal staining (63% vs. 36%, p = 0.004), abnormal Schirmer tests (39% vs. 25%, p = 0.049), and moderate OSDI symptoms (17% vs. 7%, p = 0.028). The percentage with abnormal TBUT increased with higher numbers of topical medications and was high with both benzalkonium chloride-containing and preservative-free eye drops (90% and 94%, respectively, both p < 0.001). Benzalkonium chloride was associated with a nearly three times higher odds ratio of showing abnormal OSDI. CONCLUSIONS: Ocular surface disease is common in those using topical antiglaucoma medications. Abnormal TBUT is associated with increasing number of eye drops and benzalkonium chloride-containing eye drops, although this also occurs with the use of preservative-free eye drops.
