[ case of acute retinal necrosis following herpetic encephalitis]

To report a case of acute retinal necrosis following herpetic encephalitis. A 25-year-old male presented with pain and visual loss in his left eye. He had herpetic encephalitis 1 month prior to the visual symptoms. Ophthalmologic examination and paraclinical evaluation disclosed acute retinal necrosis. Herpetic encephalitis may be a risk factor for acute retinal necrosis. The virus may reach the eye by transaxonal route

[Epidemiologic aspects of penetrating eye trauma in subjects younger than sixteen years at feiz hospital in 2009]

To report the characteristics of children referred to the emergency department of Feiz Medical Center with penetrating eye injuries. In a cross-sectional study, children with penetrating eye trauma were evaluated. Age, sex, parents educational level, time, location, and cause of trauma recorded and compared. Overall, 100 patients with mean age of 7 +/- 3.8 [range 2 to 16 years] including 69 male and 31 female were assessed. 57 eye injuries occurred at home, time of trauma was in the morning in 47% of patients. The most common cause of injury was knife [26%] and wood was the second common cause [17%]. Overall, 29 child were alone at the time of injury .The most common type of injury was corneal laceration [71%]. All traumatic cases were unilateral. Most children were injured in the early morning, therefore education of parents and other child care givers for more attention to children and improvement of health education about eye trauma may prevent pediatric eye injuries

Causes and anatomical site of blindness and severe visual loss in Isfahan, Islamic Republic of Iran

This study in 2005 evaluated the causes and major anatomical site of blindness and severe visual loss at a school for blind children in Isfahan province, Islamic Republic of Iran. All 211 students were examined according to the modified WHO/PBL eye examination record: 70.4% were blind, 24.3% had severe visual loss and 5.3% were visually impaired. The major causes of abnormality were hereditary factors [42.7%], prenatal/ neonatal [18.5%] and unknown etiology [35.5%]. The main sites of abnormality were the retina [62.6%], whole globe [17.5%], lens [7.1%] and optic nerve [7.1%]. A high proportion of parents were in a consanguineous marriage [49.2%]. The pattern of blindness in Isfahan encompasses characteristics of both developed and developing countries

Deep Vitrectomy with and without Silicone Oil in Infectious Endophthalmitis

To evaluate the efficacy of silicone oil injection after deep vitrectomy in infectious endophthalmitis regarding visual acuity. This single-blind randomized clinical trial was performed on 50 cases of infectious endophthalmitis undergoing deep vitrectomy. Patients were randomly assigned to two groups: in one group silicone oil was injected into the eye at the end of the operation [silicone group] and in the second group the eye was formed with balanced salt solution [non-silicone group]. All patients were followed for more than six months. The underlying cause of endophthalmitis was cataract surgery in 23 patients [46%], trauma in 20 patients [40%], bleb-associated endophthalmitis in 3 patients [6%], corneal graft in 2 patients [4%] and endogenous in 2 patients [4%]. Mean visual acuity was 2.1 LogMAR in the silicone group and 4.0 LogMAR in the non-silicone group [P< 0.0001]. Silicone oil injection may be beneficial in terms of visual outcomes in deep vitrectomy for infectious endophthalmitis

[Clinical patterns of uveitis in an Iranian tertiary eye care center]

To analyze the clinical patterns and etiologic diagnosis of uveitis in Isfahan. The records of 329 patients with uveitis referred to Farabi tertiary eye care center in Isfahan during 1999-2002 were classified and analyzed. Mean age of onset of uveitis was 33.2 years. The female to male ratio was 1.19:1. Anterior uveitis was the most common type [29.2%] followed by panuveitis [26.7%], posterior uveitis [23.7%], and intermediate uveitis [20.4]. The most prevalent causes were: idiopathic and Fuch's heterochromia iridiocyclitis [FHI] in anterior uveitis, toxoplasmosis in posterior uveitis, idiopathic in intermediate uveitis; and Behcet's disease and idiopathic in panuveitis. Overall, 35.5% were idiopathic, 12.1% had specific ocular disease, and 52.3% had systemic disease associations. The most common known etiologies were toxoplasmosis [22.2%], Behcet's disease [18.6%], and FHI [9.4%]. Chronic [67.2%], nongranulomatous [90.9%], and noninfectious uveitis [73.3%] were the most frequent types. The most frequent cause under 16 years of age was pars planitis. Significant differences were seen in the clinical and etiologic pattern of uveitis in Isfahan; for example the higher frequency of uveitis due to toxoplasmosis, Behcet's disease and FHI. Environmental, genetic, and geographical factors may contribute to this difference
