Ocular Histoplasmosis Treatment Treatment options for Ocular Histoplasmosis (OH) are available at several web sites. All sites indicated that laser treatment is an option; however the National Eye Institute states laser treatment is the only proven treatment. The site also warns that vision will be irreversibly lost at the location where treatment is applied.1 The Retina Source is more vague identifying treatments. It indicates that treatment is not necessary unless abnormal blood vessels are in the area of central vision. They reference the option of surgical removal of blood vessels but do not give details of success rate. This is not very informative for someone who may be experiencing OH. 2 The Eye Surgeons of Indiana web site is more thorough in identifying treatment options. These include traditional focal laser, photodynamic therapy, transpupillary thermotherapy, intraocular steroid injection, and submacular surgery.3 Search Engine Name Google 1 Search Engine URL Search String # of Hits www.google.com Ocular Histoplamosis Treatment 20,800 http://www.nei.nih.gov/health/histoplasmosis/ http://www.theretinasource.com/conditions/histoplasmosis.htm 3 http://www.eyesurgeonsofindiana.com/ocular_histoplasmosis.htm 2
