Focus on triamcinolone acetonide as an adjunct to glaucoma filtration surgery.
Glaucoma is one of the most common causes of irreversible blindness worldwide. Despite continued advances in medical and laser therapy, incisional surgery still appears to be an important and for many cases the only option by which intraocular pressure is controlled. Unlike many other types of surgery in which complete healing of tissue would be a desirable outcome, glaucoma surgery seeks to achieve incomplete healing to allow aqueous humor to escape the eye. Pharmacologic modulation of wound healing is a hot topic in glaucoma filtration surgery. Although routine antifibrotic medications are associated with good results in modulating wound healing in glaucoma surgery, they carry with them the possibility for significant morbidity due to the adverse effects of treatment. Challenge continues to be to find a safe and effective agent for this purpose. Because of beneficial effects of triamcinolone acetonide in some conditions which are associated with secondary glaucoma and also potential effects of this agent in modulating wound healing process, we propose it as a useful adjunct to glaucoma filtration surgery. This approach may allow modulation of wound healing with less of the toxicity associated with commonly used antifibrotics (5-FU and mitomycin C).

LASIK after retinal detachment surgery.
PURPOSE: To compare, in the same individuals, the safety and efficacy of laser in situ keratomileusis (LASIK) in eyes with and without previous retinal detachment surgery. METHODS: In a prospective clinical trial, seven myopic patients who had previously undergone scleral buckling surgery in one eye underwent conventional LASIK surgery in both eyes. Uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), refraction, Orbscan topography and pachymetry were recorded before and 1, 3, 6 and 12 months after surgery. The eyes were divided into two groups: group 1 consisted of eyes that had undergone previous surgery for retinal detachment, and group 2 consisted of the fellow eyes of the same patients, which had not undergone any previous ocular surgery. Student's t-test for match-paired data was used to evaluate the significance of differences. RESULTS: LASIK was performed successfully in all patients. The UCVA improved in all eyes in both groups. The mean change in the spherical equivalent between 1 and 12 months after LASIK surgery was 1.7 +/- 1.1 and 0.6 +/- 0.5 diopter in groups 1 and 2, respectively (p = 0.019). CONCLUSION: LASIK may be considered for treatment of myopia in eyes that have had previous surgery for retinal detachment. However, the risk of regression may be higher in such eyes than in eyes with no previous scleral buckling surgery.

Potential role of uric acid in the molecular pathogenesis of age-related macular degeneration.
Age-related macular degeneration (ARMD) is the foremost cause of blindness among the elderly population in industrialised countries. Currently, there is no effective treatment for the majority of patients. To develop new and effective modes of therapy, understanding of the molecular basis of the disease is mandatory. Many age-related pathologies have been attributed to cumulative oxidative damage caused by reactive oxygen intermediates. There is growing evidence that uric acid has antioxidant properties and it is a naturally occurring antioxidant. Based on antioxidant role in pathogenesis of ARMD and antioxidant properties of uric acid we conclude that altered uric acid metabolism could play a role in ARMD damage and pathogenesis. Future research needs to evaluate uric acid metabolism in ARMD patients.
