OBJECTIVETo explore the use of triamcinolone acetonide for the prevention of implant capsular contracture.

METHODS20 rabbits were randomly undivided into 2 groups of 10 animals each. Every 10 ml silicone implant was implanted beneath the panniculus carnosus muscle of one rabbit. At the same time, a modified expander catheter was mounted on the implant. This catheter has many lateral holes and the end was blind. Triamcinolone acetonide (10 mg/3 ml) was infused through the expander pot and catheter as the experimental groups. On the other hand, 3 ml saline was used as the control group at 1, 2, and 3 months. At 6 months, measures related to contracture and capsular histology examinations were performed on anesthetized animals.

RESULTSBaker scores, capsular incision width and capsular thickness of the saline groups were evidently higher than that of triamcinolone acetonide groups (P < 0.01). Implant compression of the saline groups was evidently lower than that of triamcinolone acetonide group. Histology revealed a thinner capsules and less fibrous tissue deposition around the triamcinolone acetonide group, as compared with saline group.

CONCLUSIONSIt is effective to deliver triamcinolone acetonide to reduction of capsular contracture through the catheter and its pot.

PURPOSE: This study investigated firstly the change of intraocular pressure (IOP) after injection of intravitreal triamcinolone acetonide (IVTA) for the treatment of macular edema and secondly the factors that influence these changes. METHODS: A prospective, non-comparative study was performed in 60 patients at Kangnam Sacred Heart Hospital from October 2003 to September 2004. All the patients received 4-mg IVTA injection. RESULTS: Mean IOP was elevated from the day after injection and peaked at 20.5 mmHg after 2 months (p=0.000). Twenty-six eyes (43.3%) showed significant IOP elevation. IOP was not controlled despite full glaucoma medication in 7 (11.7%) eyes. Two eyes underwent filtering surgery. Younger age was a statistically significant predictive factor for IOP elevation (p=0.009). CONCLUSIONS: In this study, patients who needed filtering surgery developed an IOP spike within one week after the injection. Therefore, clinicians should consider checking IOP at the end of the first week. Furthermore, greater cautions is mandatory with relatively younger patients.

Cutaneous pseudolymphoma is an uncommon, benign lymphoproliferative disorder of the skin. Although this condition is most commonly idiopathic, its occurrence has been associated with cosmetic tattoos. We report a unique case of cutaneous pseudolymphoma that occured after accidental, traumatic inoculation of a red pigment in a healthy 33-year-old woman.

A 56-year-old man presented with anterior chamber inflammation, increased intraocular pressure, peripheral retinal infiltration, and generalized retinal arterial obstruction suggesting acute retinal necrosis five months after intravitreal triamcinolone acetonide injection (IVTA). He was treated with intravenous antiviral agents and aspirin. Shortly after treatment, retinal infiltrations were resolved, and partial recanalization of the obstructed vessel was observed. Viral retinitis may occur as an opportunistic infection following IVTA due to the local immune modulatory effect of the steroid; hence, close observation following IVTA is necessary.

To report a case of cytomegalovirus (CMV) retinitis after intravitreal injection of triamcinolone acetonide (IVTA). A 77-year-old woman with macular edema due to central retinal vein occlusion (CRVO) developed peripheral retinitis 4 months after IVTA. A diagnostic anterior chamber paracentesis was performed to obtain DNA for a polymerase chain reaction (PCR) test for viral retinitis. The PCR test was positive for CMV DNA. Other tests for infective uveitis and immune competence were negative. Four months after presentation, gancyclovir was intravitreously injected a total of 5 times, and the retinitis resolved completely. CMV retinitis is a rare complication of local immunosuppression with IVTA. It can be managed with timely injection of intravitreal gancyclovir until recovery from local immunosuppression.

A 3-year-old Thoroughbred filly was referred to the Equine Hospital, Korea Racing Association for evaluation of hematuria, inappetite, weight loss and depression. From 25 days prior to admission, the horse was treated for right carpal lameness with 20 mg intramuscular administration of triamcinolone acetonide per day for consecutive 10 days by a local veterinarian. Clinical and laboratory findings included vaginal hyperemia, flare in bladder wall, neutrophilia, lymphopenia, polyuria, polydipsia and laminitis in the end. High activities of aspartate transaminase and gamma glutamyltransferase and high concentration of total bilirubin indicated hepatopathy. Further hematology, serum biochemistry and urinalysis did not reveal any abnormalities. Medical history, physical and clinicopathologic findings suggest that the laminitis and hepatopathy in this horse were most likely induced by repeated administration of exogenous corticosteroid. However, guarded prognosis of treating laminitis undermined the benefit of improvement of hematuria following electroacupuncture stimulation. The combined stimulation of kidney related acupoints (Shen Peng, Shen Shu), lumber related acupoints (Yao Qian, Yao Zhong) and associate acupoints (Guan Yuan Shu, Bai Hui) at 5Hz, 1-2V, for 40 minutes was of value in the treatment of hematuria. This case shows that horses under steroids may exhibit laminitis and steroid hepatopathy. Early recognition and good management of laminitis are important in the limitation of complications.
