ABSTRACT
BACKGROUND: The purpose of this study was to evaluate the immunoglobulin (Ig) G avidity of serological toxoplasmosis testing in patients with ocular inflammation and to determine the clinical manifestations of ocular toxoplasmosis. METHODS: A retrospective review of all patients presenting with ocular inflammation to the Hospital Universiti Sains Malaysia, Kelantan, Malaysia between 2005 and 2009 was undertaken. Visual acuity, clinical manifestations at presentation, toxoplasmosis antibody testing, and treatment records were analyzed. RESULTS: A total of 130 patients with ocular inflammation were reviewed retrospectively. The patients had a mean age of 38.41 (standard deviation 19.24, range 6-83) years. Seventy-one patients (54.6%) were found to be seropositive, of whom five (3.8%) were both IgG and IgM positive (suggestive of recently acquired ocular toxoplasmosis) while one (0.8%) showed IgG avidity ≤40% (suggestive of recently acquired ocular toxoplasmosis) and 65 patients (50.0%) showed IgG avidity >40% (suggestive of reactivation of toxoplasmosis infection). Chorioretinal scarring as an ocular manifestation was significantly more common in patients with seropositive toxoplasmosis (P = 0.036). Eighteen patients (13.8%) were diagnosed as having recent and/or active ocular toxoplasmosis based on clinical manifestations and serological testing. CONCLUSION: Ocular toxoplasmosis is a clinical diagnosis, but specific toxoplasmosis antibody testing helps to support the diagnosis and to differentiate between reactivation of infection and recently acquired ocular toxoplasmosis.
ABSTRACT
The reconstruction of the upper eyelid with medial canthal involvement post extensive removal of malignant tumour remains a challenge. Proper eyelid reconstruction is necessary to re-establish anatomic integrity, restoration of its functions and to maintain the best cosmetic appearance. These case reports illustrate an alternative reconstructive technique for large upper eyelid full thickness defect with medial canthal involvement. Two cases of upper eyelid tumours involving medial canthal region underwent staged reconstruction by glabellar flap advancement and reconstruction of the posterior lamellar with autologous graft using buccal mucosa and ear cartilage. The posterior lamellar graft and flap survived without any complication except for mild eyelid margin notching in one of the two cases. The staged reconstruction with glabellar flap advancement provides adequate defect coverage, excellent blood supply, maintains eyebrow contour and function of the eyelid. The flap also perfectly matches the surrounding tissue with minimal donor site morbidity.
ABSTRACT
·AIM: To evaluate the clinical presentations of traumatic optic neuropathy and to assess the visual outcome of three groups of patients managed differently (conservative, intravenous corticosteroids only and combination of intravenous and oral corticosteroids) at an academic tertiary care referral centre.·METHODS: A retrospective study was conducted involv-ing 24 consecutive patients (27 eyes) with traumatic optic neuropathy attending Hospital Universiti Sains Malaysia from January 2007 till December 2009.·RESULTS: Twenty-four patients (27 eyes) were included. All cases involved were male. Mean age was 33 years old. Motor vehicle accident was the major cause (83%). Both eyes were equally involved. Most of the eyes had poor vision on presentation (HM-NPL, 82%) with associated periorbital haematoma (22 eyes) and subcon-junctival haemorrhage (20 eyes). Majority of patients (19 patients, 79%) presented with more than one bony fracture of skull or orbit and 5 patients (21%) had no fractures. None of the patients had evidence of optic nerve compression on CT scans or MRI done. Eleven patients (46%) had been treated with intravenous and oral corticosteroids. The other 7 patients (29%) were treated conservatively and the third group (6 patients, 25%) was on intravenous corticosteroids only. Eleven of 12 eyes (92%) treated with intravenous and oral corticosteroids had showed 1 line improvement of visual acuity. Those eyes treated conservatively (78%) had showed 1 line improvement of visual acuity. As for patients treated with intravenous corticosteroids only, four patients remained NPL, one patient had mild visual improvement and the other one's vision remained the same. The visual improvement in patients treated with conservative management was not significant (P=0.386). Patients treated with intravenous corticosteroids alone have shown no statistical visual improvement (P<0.05). Patients treated with intravenous followed by oral corticosteroids had significant visual improvement (P<0.05). There was no statistically significant difference in visual outcome between patients treated with corticoster-oids and patients treated conservatively (P=0.368). No patient underwent surgical decompression of the optic nerve. In this series, the follow-up ranged from 6 months to 3 years.·CONCLUSION: Most of the traumatic optic neuropathy patients are presented with periorbital haematoma, subconjunctival haemorrhage and orbital wall fractures. Patients treated with intravenous followed by oral corti-costeroids have better visual outcome compared to conservative management.
