ABSTRACT

PURPOSE: To report a newly recognised advert event of clarithromycin. METHODS: Retrospective, case report. RESULTS: A 30-year old female referred to our centre with bilateral diffuse iris atrophy after the use of oral clarithromycin for a pulmonary infection. CONCLUSIONS: Bilateral acute depigmentation of the iris is a new clinical entity. Iris transillumination and sphincter paralysis are recognised adverse effects of oral antibiotic therapy, but to our knowledge no other publication has referred to uveitis-like syndrome due to oral administration of clarithromycin.

ABSTRACT

PURPOSE: To evaluate the effect of 24-h peak intraocular pressure (IOP) on the progression of primary open-angle glaucoma (POAG) and the 24 h time points that best predict peak pressure. METHODS: A retrospective analysis of clinical data evaluating long-term glaucomatous progression in patients with POAG who were previously in a 24-h study of the authors (IOP readings at 2/6/10 A.M. and 2/6/10 PM); had ≥3 treated 10 A.M. (±1 h) IOP measurements over 5-years after an untreated 24-h baseline; and had a treated 24-h curve with a 10 A.M. IOP±2 mmHg within the 10 A.M. mean IOP over 5-years. RESULTS: We included 98 nonprogressed and 53 progressed patients with POAG (n=151). The mean 24-h peak IOP (mmHg) was 19.9±2.7 for progressed and 18.3±2.0 for nonprogressed patients (P<0.001). Progressed patients also showed a higher mean 24-h IOP. Generally, patients with a mean or peak daytime (readings at 10 A.M., 2 and 6 P.M.) or 24-h peak IOP of ≤18 remained nonprogressed in 75%-78% of cases. Further, measuring IOP at night found a higher peak in only 20% of cases, which was ≤2 of the daytime peak in 98% of cases. A multivariate regression analysis showed only 24-h peak IOP as an independent risk factor for progression (P=0.002). CONCLUSIONS: This study suggests that daytime peak IOP may be clinically important in predicting long-term glaucomatous progression. Further, daytime peak IOP may assist, as much as daytime mean IOP and, in most cases, 24-h peak IOP, in helping to guide long-term treatment in POAG.

ABSTRACT

PURPOSE: The evaluation of long-term visual outcome after the use of bevacizumab for the management of multilevel hemorrhage due to retinal arterial macroaneurysm (MA). CASE REPORT: A 71-year-old hypertensive female presented with sudden reduction of visual acuity in her left eye (OS). Fundoscopy revealed an arterial macroaneurysm with preretinal and subretinal hemorrhage in the eye. Due to significant macular involvement, the patient received two intravitreal injections of bevacizumab within 2 months. RESULTS: Significant visual and anatomical recovery was observed 2 months later, which was confirmed by fluorescein angiography. At the end of a follow-up period (39 months) visual acuity and visual field were at normal levels. CONCLUSION: Retinal MA is a relatively rare condition. Anti-vascular endothelial growth factor therapy appears a safe and effective treatment option for selected symptomatic individuals that may offer faster visual rehabilitation. Herein we report, for the first time, a 39-month follow-up of a retinal MA treated with anti-vascular endothelial growth factor therapy.

ABSTRACT

INTRODUCTION: Traumatic macular holes (TMH) are well-known complications of ocular contusion injury. Spontaneous closure occurs in approximately 50% of cases, but rarely after the age of thirty. We report a case of spontaneous closure of a full thickness macular hole due to a blunt trauma and we suggest possible mechanisms for this closure. CASE PRESENTATION: A 50-year-old Greek woman was referred with a history of reduced best-corrected visual acuity after blunt trauma to her right eye. Diagnosis was based on fundoscopic, optical coherence tomography as well as fluorescein angiography findings with follow-up visits at two days, 20 days and five months. Fundoscopy revealed a full-thickness TMH with a minor sub-retinal hemorrhage and posterior vitreous detachment. The presence of a coagulum in the TMH base was observed. Subsequently, TMH closure was observed. CONCLUSION: The clot in the TMH base, potentially a hemorrhage by-product containing a significant quantity of platelets, may have simulated the clot observed after autologous serum use, thus facilitating a similar effect. This may have stimulated glial cell migration and proliferation, thus contributing to spontaneous hole closure.

ABSTRACT

PURPOSE: Abetalipoproteinemia is a very rare disease with multisystemic manifestations. METHODS: Retrospective, case report. RESULTS: We report a 9-year-old girl with a history of Bassen-Kornzweig syndrome diagnosed at the age of 3. The patient was referred to us by the pediatricians for ocular assessment. During the examination, an atypical pigmentary retinopathy and bilateral swelling of the optic discs were observed, with no consequences to her visual acuity. CONCLUSIONS: Ophthalmic manifestations in Bassen-Kornzweig syndrome are not uncommon. We describe, for the first time, bilateral swelling of the optic discs, a sign that appears directly associated with abetalipoproteinemia.

ABSTRACT

PURPOSE: To evaluate intraocular pressure (IOP) control over 24 hours using travoprost and timolol fixed combination (TTFC) administered in the morning or evening in primary open-angle and exfoliative glaucoma. METHODS: Patients were randomized to TTFC administered in either the morning or evening for 8 weeks. Previously treated patients underwent an untreated washout period of 4-6 weeks, after which baseline IOP was required to be > 25 mm Hg and < 38 mmHg (in two readings taken at 10.00 +/- 1 hours). During the treatment period, IOP was measured at 10.00, 14.00, 18.00, 22.00, 02.00 and 06.00 hours. Patients were then treated with the opposite dosing regimen for 8 weeks and IOP measurements were repeated. RESULTS: In 32 subjects who completed the study, the untreated baseline IOP following washout was 27.7 +/- 3.5 mmHg. Both dosing regimens reduced IOP from baseline at each time-point and throughout the 24-hour diurnal curve (p < 0.0001). When treatments were compared directly, evening dosing (18.4 +/- 3.3 mmHg) provided a statistically significant lower 24-hour curve than morning dosing (19.2 +/- 3.5 mmHg; p = 0.001). Evening dosing also resulted in a lower 24-hour IOP fluctuation (3.8 +/- 1.6 mmHg) than morning dosing (5.1 +/- 1.6 mmHg; p = 0.0002) and lower peak IOP (p = 0.0003). CONCLUSIONS: Both morning and evening administration of TTFC provide effective 24-hour IOP reduction, but evening dosing demonstrates better 24-hour pressure control.
