Intravitreal triamcinolone acetonide for serous retinal pigment epithelial detachments in exudative age-related macular degeneration

BACKGROUND: Due to the high risk of RPE tears PDT is usually not performed in eyes with serous RPE detachments (sRPED). For this reason this subform of exudative AMD was so far untreatable. PATIENTS AND METHODS: We report on a prospective uncontrolled observational case series. 20 eyes of 20 patients with subfoveal sRPED demonstrated by OCT were treated between June 2005 and April 2006 with intravitreal triamcinolone acetonide (IVTA). In 15 cases there was a primary sRPED, in 5 cases it had developed after one or more sessions of photodynamic therapy with Visudyne. RESULTS: There was a trend for better average visual acuity in the group with primary sRPED from 0.73 logMAR (0.19 Snellen equivalent) at baseline (n = 15) to 0.68 logMAR (0.21 Snellen) after one month (n = 15) (p = 0.19) and to 0.60 logMAR (0.25 Snellen) after three months (n = 14) (p = 0.41). The maximal height of sRPED decreased to an average of 35.3 % after one month (n = 15) and increased again to 56.9 % after 3 months (n = 14). One patient was lost to follow-up. In the group of eyes with sRPED after PDT, one eye developed an RPE tear with severe vision loss two weeks after IVTA. In the remaining four eyes average visual acuity improved from 0.90 logMAR (0.13 Snellen) at baseline to 0.73 logMAR (0.19 Snellen) after one month and to 0.80 logMAR (0.16 Snellen) after 3 months. Complete resolution of sRPED was observed in 8/20 eyes (4/5 eyes with sRPED after PDT and 4/15 eyes with primary sRPED). CONCLUSIONS: IVTA seems to be a therapeutic option in otherwise untreatable eyes with sRPED.

Comparison between intravitreal and orbital floor triamcinolone acetonide after phacoemulsification in patients with endogenous uveitis

PURPOSE: To compare the effect of intravitreal and orbital floor triamcinolone acetonide (TA) on macular edema, visual outcome, and course of postoperative inflammation after cataract surgery in uveitis patients. DESIGN: Prospective, randomized clinical trial. METHODS: Monocenter study (40 patients) with chronic endogenous uveitis who underwent phacoemulsification with intraocular lens implantation with either 4 mg intravitreal TA (n = 20) or 40 mg orbital floor TA (n = 20). The primary outcome was influence on cystoid macular edema (CME). Secondary outcome measures were best-corrected visual acuity (BCVA), anterior chamber cell grade, laser flare photometry, giant cell deposition, posterior capsule opacification (PCO), and intraocular pressure. RESULTS: Mean central foveal thickness decreased in the intravitreal TA group and increased in the orbital floor TA group (P < .001 at one and three months). CME improved in 50% of patients after intravitreal TA, whereas it was unchanged after orbital floor TA (difference between the groups at three months, P = .049). Mean BCVA (logarithm of the minimal angle of resolution) improved postoperatively (P < .001) from 0.76 and 0.74 to 0.22 and 0.23 in the intravitreal TA and orbital floor TA group, respectively. Anterior chamber cell count at one month was lower in the intravitreal TA than in the orbital floor TA group (P = .02). Laser flare photometry values and giant cell numbers were slightly higher after orbital floor TA than after intravitreal TA. The groups did not differ with respect to PCO rate and ocular hypertension. CONCLUSIONS: The CME improvement and anti-inflammatory effect after intravitreal TA was better than after orbital floor TA injection in cataract surgery in uveitis patients.

Oil-soluble vitamins: illegal use for lip augmentation.

Fillers for lip augmentation have become more and more popular in recent years and seem to be indispensable in the cosmetic market nowadays. A series of six young females is presented who developed massive swellings and pain after vitamins A and/or E lip augmentation. The vitamins were extracted from gelatinous capsules (Gericaps [Adipharm EAD, Sofia, Bulgaria], Geritamins [Actavis EAD, Balkanpharma-Dubnitsa AD, Bulgaria], or vitamin E yellow gel capsules) and injected by unprofessional physicians and beauticians in different cosmetic centers. Physical examination revealed firm indurations of the lips and perioral skin, tenderness, erythema, and hard dermal nodules. Histological analysis revealed numerous round-to-ovoid cavities of varying sizes, resulting in a Swiss cheese-like appearance, consistent with lipogranulomas. The patients were treated with systemic and intralesional triamcinolone injections and broad-spectrum antibiotics with good clinical response. In conclusion, these cases demonstrate the danger of the use of unregistered products as fillers injected by unprofessional physicians and beauticians.

MRI-guided and CT-guided cervical nerve root infiltration therapy: a cost comparison

PURPOSE To evaluate and compare the costs of MRI-guided and CT-guided cervical nerve root infiltration for the minimally invasive treatment of radicular neck pain. MATERIALS AND METHODS Between September 2009 and April 2012, 22 patients (9 men, 13 women; mean age: 48.2 years) underwent MRI-guided (1.0 Tesla, Panorama HFO, Philips) single-site periradicular cervical nerve root infiltration with 40 mg triamcinolone acetonide. A further 64 patients (34 men, 30 women; mean age: 50.3 years) were treated under CT fluoroscopic guidance (Somatom Definition 64, Siemens). The mean overall costs were calculated as the sum of the prorated costs of equipment use (purchase, depreciation, maintenance, and energy costs), personnel costs and expenditure for disposables that were identified for MRI- and CT-guided procedures. Additionally, the cost of ultrasound guidance was calculated. RESULTS The mean intervention time was 24.9 min. (range: 12 - 36 min.) for MRI-guided infiltration and 19.7 min. (range: 5 - 54 min.) for CT-guided infiltration. The average total costs per patient were EUR 240 for MRI-guided interventions and EUR 124 for CT-guided interventions. These were (MRI/CT guidance) EUR 150/60 for equipment use, EUR 46/40 for personnel, and EUR 44/25 for disposables. The mean overall cost of ultrasound guidance was EUR 76. CONCLUSION Cervical nerve root infiltration using MRI guidance is still about twice as expensive as infiltration using CT guidance. However, since it does not involve radiation exposure for patients and personnel, MRI-guided nerve root infiltration may become a promising alternative to the CT-guided procedure, especially since a further price decrease is expected for MRI devices and MR-compatible disposables. In contrast, ultrasound remains the less expensive method for nerve root infiltration guidance.

Idiopathic multifocal choroiditis/punctate inner choroidopathy with acute photoreceptor loss or dysfunction out of proportion to clinically visible lesions.

PURPOSE To report acute/subacute vision loss and paracentral scotomata in patients with idiopathic multifocal choroiditis/punctate inner choroidopathy due to large zones of acute photoreceptor attenuation surrounding the chorioretinal lesions. METHODS Multimodal imaging case series. RESULTS Six women and 2 men were included (mean age, 31.5 ± 5.8 years). Vision ranged from 20/20-1 to hand motion (mean, 20/364). Spectral domain optical coherence tomography demonstrated extensive attenuation of the external limiting membrane, ellipsoid and interdigitation zones, adjacent to the visible multifocal choroiditis/punctate inner choroidopathy lesions. The corresponding areas were hyperautofluorescent on fundus autofluorescence and were associated with corresponding visual field defects. Full-field electroretinogram (available in three cases) showed markedly decreased cone/rod response, and multifocal electroretinogram revealed reduced amplitudes and increased implicit times in two cases. Three patients received no treatment, the remaining were treated with oral corticosteroids (n = 4), oral acyclovir/valacyclovir (n = 2), intravitreal/posterior subtenon triamcinolone acetate (n = 3), and anti-vascular endothelial growth factor (n = 2). Visual recovery occurred in only three cases of whom two were treated. Varying morphological recovery was found in six cases, associated with decrease in hyperautofluorescence on fundus autofluorescence. CONCLUSION Multifocal choroiditis/punctate inner choroidopathy can present with transient or permanent central photoreceptor attenuation/loss. This presentation is likely a variant of multifocal choroiditis/punctate inner choroidopathy with chorioretinal atrophy. Associated changes are best evaluated using multimodal imaging.
