Conjunctival squamous cell carcinoma;

To evaluate 20 patients with squamous cell carcinoma of the conjunctiva. To determine the clinical and pathological characteristics. Retrospective study. POP hospital and EDO eye hospital Wah.Cantt From June 200 to July 2006. The patients presenting with squamous cell carcinoma of the conjunctiva were retrospectively evaluated. Patients were usually male [80%], elderly [75% >60 years of age], with most lesions [90%] occurring at the limbus. Two patients [10%] suffered recurrence of the squamous cell of the conjunctiva within 2 to 4 months of resection. Corneal invasion was noted in two patients [10%] while there was intraocular and orbital invasion in two patients [10%]. One patient [5%] required enucleation and one patient [5%] required exenteration. In situ carcinoma was noted in 18 patients [90%]. Squamous cell carcinoma of the conjunctiva occurs in the sun exposed area of the conjuntiva at the limbus in the elderly men. Recurrence was noted in the younger patients and with larger lesions. Enucleation and exenteration is required in a small number of cases

Decreasing efficacy of repeated intravitreal triamcinolone injection in diabetic macular oedema

To assess the efficacy of 4mg of repeated intravitreal injection of triamcinolone for the treatment of diabetic macular oedema. This is a case series of twenty eyes of twenty patients who received repeated injections of 4 mg of intravitreal triamcinolone at least 24 weeks after the first injection The best corrected visual acuity was compared after the first and repeated injection of intravitreal triamcinolone and at 2, 4, 8 and 12 weeks after the first and repeated injection of intravitreal triamcinolone using the paired t test. Side effects were also monitored. The best corrected visual acuity was significantly less in the repeated intravitreal injection at all follow ups [p <0.05] as compared to the initial injection of triamcinolone .The rise in the intraocular pressure and the cataract score were not significantly different in the initial and repeated injections of intravitreal triamcinolone. The repeated injection of 4 mg of intravitreal triamcinolone is not as effective as the initial injection of the same dose
