we tried to evaluate prevalence and characteristics of iranian hiv infected patients with retinitis due to opportunistic infections. in this cross sectional study, we evaluated 106 hiv infected patients via indirect ophthalmoscopy and slit lamp examination by 90 lens to find retinitis cases. general information and results of ophthalmologic examination were analyzed. prevalence of retinitis due...

800x600 unfortunately, at present, degenerative retinal diseases such as retinitis pigmentosa remains untreatable. patients with these conditions suffer progressive visual decline resulting from continuing loss of photoreceptor cells and outer nuclear layers. however, stem cell therapy is a promising approach to restore visual function in eyes with degenerative retinal diseases such as retiniti...

Background: Causes of blindness in children vary according to the region and socioeconomic development. Within a given country these causes vary with passage of time. This reflects different levels of socioeconomic development and provision of healthcare services. This cross-sectional study was undertaken to estimate the major causes of severe visual impairment in children and specially prevent...

RATIONALE Cytomegalovirus (CMV) retinitis is a common opportunistic infection in immunocompromised patients, which may lead to blindness. CMV retinitis is not an uncommon infectious disease in patients with immune regulatory abnormalities, for example, human immunodeficiency virus (HIV) patients. However, CMV retinitis in a patient with acute lymphosarcoma leukemia (ALL) undergoing allogeneic h...

Rickettsial retinitis is increasingly being reported from the Indian subcontinent.[1,2] Rickettsia has to be considered in the standard list of differential diagnosis for cases of postfever retinitis/epidemic retinitis. It is definitely controversial whether a case of epidemic retinitis is because of direct microbial invasion or an immune-mediated phenomenon. The authors of “Rickettsial retinit...

AIM To describe the risk of developing cytomegalovirus (CMV) retinitis after a first episode of extraocular CMV disease in AIDS patients. METHODS A review of the clinical records of 20 AIDS patients, without CMV retinitis, with histologically confirmed extraocular CMV disease, was performed. The main outcome measures were occurrence of CMV retinitis, time to development of CMV retinitis, rela...

Conjunctival swabs were used in combination with polymerase chain reactions (PCR) or virus culture to aid to confirm the diagnosis of cytomegalovirus (CMV) retinitis in AIDS patients. Based on ophthalmoscopic findings, 13 AIDS patients were diagnosed as having CMV retinitis and treated with systemic ganciclovir from January 1997 to December 1998. Nine of 13 AIDS patients with CMV retinitis were...
