Bilateral angle closure glaucoma following general anesthesia.

Although unilateral angle closure glaucoma is quite common, simultaneous bilateral acute angle closure is very rare and is usually induced by an external cause. General anesthesia is a triggering factor for acute angle closure glaucoma. We report two cases of simultaneous bilateral angle closure glaucoma following non-ocular surgery under general anesthesia. One patient had cholecystectomy, the other craniotomy for tumor resection. In the postoperative period following general anesthesia, any patient at risk for angle closure glaucoma should be followed closely; patients with periorbital pain and visual symptoms should be examined for angle closure glaucoma attack in both eyes.

Hypotony: an unusual consequence of intraocular lens malposition.

Common causes of postoperative hypotony include wound leakage, inflammatory reaction of the ciliary body, cyclodialysis, and ciliochoroidal detachment. We present an unusual case of ocular hypotony in a pseudophakic eye associated with distortion of the ciliary body by a decentered posterior chamber intraocular lens (IOL) haptic. A simple surgical repositioning of the IOL relieved the hypotony by eliminating the irritation by the IOL haptic on the distorted edematous ciliary body. Ciliochoroidal irritation by IOL haptics should be considered a possible cause of ocular hypotony in a pseudophakic eye.

Coexistence of intraocular eyelashes and anterior chamber cyst after penetrating eye injury: a case presentation.

We herein describe a patient in whom two intraocular eyelashes and an anterior chamber cyst embedded into the anterior surface of the iris was detected following penetrating eye injury. After a one year asymptomatic period, the patient was hospitalized because of uveitic reaction in the anterior chamber which may be due to cyst development. The lashes and cyst were removed surgically, and examined pathologically. There was no complication in one year follow-up period.

The influence of religious fasting on basal tear secretion and tear break-up time.

Muslims abstain from food and drink from dawn to sunset during the holy month of Ramadan. An extended strict fasting may influence tear secretion and quality. We investigated changes in basal tear secretion (BTS) and tear break-up time (BUT) at the beginning and at the end of fasting on 32 healthy male patients with a mean age of 22.3 +/- 2.9 years. Body weight and urine specific gravity were also determined to assess the extent of dehydration due to fasting. Each case lost 0.1-1.25 kg of body weight while urine specific gravity changes were statistically insignificant. Mean BTS amount was 19.9 +/- 10.9 mm at the initial examination and 19.7 +/- 11.5 mm at the end of fasting (p = 0.9). BUT values were 20.1 +/- 9.3 sec at the beginning of fasting and 23.5 +/- 14.9 sec at the end of fasting (p = 0.19). We found that religious fasting in the winter season does not seem to affect BTS and BUT values in healthy individuals.

Fluorescein dye disappearance test in patients with different degrees of epiphora.

PURPOSE: To assess the diagnostic efficacy of a modification of the fluorescein dye disappearance test (DDT) in patients with different degrees of epiphora. METHODS: DDT was performed by instilling a drop of 2% fluorescein in the eye. Schirmer tear test strips were placed in the lower conjunctival fornix, after 3 and 10 minutes. The colour dilution on the strips was compared to a scale with known standards and the most closely comparable colour dilution was chosen and recorded as the visual scale test (VST) grade of the strip. The grey-scale value (GV) of each strip was calculated by computer image analysis. The control group comprised 44 patients, mean age 44.8 years (SD 7.5, range 30-60). There were 13 patients in group 1 with moderate epiphora; mean age was 44.2 years (SD 9.5, range 30-60). There were 17 patients in group 2 with severe epiphora; mean age was 48.3 years (SD 7.7, range 37- 60). RESULTS: VST and GV differed significantly between controls and group 1 patients at 3 minutes (p=0.002, p=0.001), and between controls and group 2 patients at 3 minutes (p<0.001, p<0.001). There was no difference between groups 1 and 2 patients in VST and GV at 3 minutes. The differences were highly significant between controls and group 1 at 10 minutes (p=0.001, p=0.007), and between controls and group 2 at 10 minutes (p<0.001, p<0.001). The differences in GV and VST between groups 1 and 2 were significant at 10 minutes (p=0.026, p=0.018). CONCLUSIONS: This modified DDT permits identification of different degrees of epiphora in a non-invasive manner, it can therefore be used to evaluate the outcome of different treatment strategies.
