ABSTRACT
Purtscher's retinopathy occurs with sudden loss of vision. In this article, a case of post-partum Purtscher's-like retinopathy was investigated. The patient was an 18-year-old woman who presented with severe bilateral loss of vision, three days after childbirth. No systemic abnormalities were observed except preeclampsia. The results of ophthalmoscopy and fluorescein angiography, multiple superficial white patches within the retina, and small superficial indicated retinal hemorrhage simulating Purtscher's retinopathy. After eight weeks, visual acuity had significantly improved without any treatment. Embolic occlusion of the precapillary arterioles is the most likely pathogenesis. Also, improvement of visual outcomes may be seen in patients with post-partum Purtscher's-like retinopathy
ABSTRACT
Pterygium is a common ocular disorder throughout the world. The purpose of this study was to evaluate the efficacy of simple excision alone with or without topical mitomycin in the treatment of pterygium. This study was performed in two stages. In the first stage, from 1991 to 1994, 100 patients [group 1] were operated on with simple excision and in the second stage, from 1995 to 1999, 300 patients [group 2] were treated with the same procedure plus topical mitomycin [0.02% eye drops four times a day for 4 days after operation]. All cases were followed for 5 years. The recurrence rate of pterygium in these two treated groups were compared. The mean age of the subjects was 49 +/- 13 years in group 1 and 47 +/- 17 years in group 2. The clinical manifestations in these two groups were two groups were similar [P>0.05]. After one year, relapse was seen in 21 cases [21%] in group 1 and in 3 cases [1%] in group 2. After five years, 31 cases [31%] in group 1 and 3 cases [1%] in group 2 had relapse [P=0.0001]. The mean time to recurrence at five years for the simple excision group was 3.83 years [95% CI: 3.48 to 4.17 years] and for simple excision plus mitomycin C was 4.96 years [95% CI: 4.91 to 5.0 years] [P<0.0001]. Instillation of mitomycin C eye drops appears to be safe in the treatment of pterygium
