Comparison of Hirschberg Test with Prsim and Alternate Cover Test in Measuring the Ocular Deviation

Measurements of ocular deviation were obtained from 45 exotropes and 31 esotropes, using Hirschberg corneal reflex test, and prism and alternate cover test respectively. The mean angle of devation in exotropes was 27.42 +/- 8.60 delta by Hirschberg test, 27.80 +/- 8.11 delta by prism and alternate cover test. There was no significant difference between these two groups (p>0.05). The mean angle of deviation in esotropes was 28.55 +/- 12.92 delta by Hirschberg test, 31.58 +/- 13.08 delta by prism and alternate cover test. The difference between these two groups was significant (p<0.05). In patients whose angle kappa was zero and exotropes whose angle kappa was positive, there was no significant diHerence between the two tests. In esotropes whose angle kappa was positive, the mean angle of deviation was 29.74 +/- 15.59 delta by Hirschberg test, and 33.47 +/- 15.91 delta by prism and alternate cover test. The difference between the two groups was significant (p

Triple Procedure in Glaucoma Patients

The author reviewed the effectiveness of triple procedure in terms of the visual acuity and the intraocular pressure control after 6 months follow up of twenty-four consecutive glaucoma patients who was treated with triple procedure: trabeculectomy with simultaneous lens extraction and intraocular lens implanation. At 6 months after operation, the mean intraocular pressure was 7.0mmHg lower than the preoperative level, and the kind of glaucoma medication was decreased from 2.1 to 0.6. The visual acuity improved in 67% at two months and 93% at six months after operation, respectively. The several complications such as hyphema, shallow anterior chamber with wound leaking, posterior capsular opacity and uncontrolled intraocular pressure were appeared. Effectiveness of triple procedure in terms of intraocular pressure control and visual acuity improvement seems to be similar to that of the operation done separately.

Multiple Evanescent White Dot Syndrome

Multipe Evanescent White Dot Syndrome is a clinical disorder of unknown etiology usually resulting in acute visual loss It affects primarily the retinal pigment epithelium and photoreceptors, Ocular manifestations may include multiple white dots at the level of the retinal pigment epithelium, granulaity of the macula, optic nerve swelling and anterior chamber and vitreous cells. Fluorescein angiogram discloses hyperfluorescence in association with the white spots and late staining and dye leakage from disc capillaries. We experienced a case of Multiple Evanescent White Dot Syndrome and reviewed the available literatures regarding this disease.

Purtscher's-lke Retinopathy in Patients with Systemic Hypertension

Since Purtscher's original discriptions similar clinical signs have been described following acute compressive neck or chest injuries, chest compression, val salva maneuvers, long bone fractures, acute pancreatitis and after childbirth. The appearance of Purtscher's retinopathy are believed to be due to ischemic episodes particularly in the end arterioles around the macula and disc. We experienced two cases of Purtscher's-like retinopathy in patients with systemic hypertension who had not any recent trauma history and reviewed the available literatures regarding this disease.
