This study suggests that intraoperative applications of 5-fluorouracil is both efficient and safe in the treatment of primary pterygium. Additionally, postoperative subconjunctival 5-fluorouracil injections may prevent the progression of fibrovascular tissue.
Purpose: To prospectively investigate the impact of various hormone replacement therapies (HRT) on ocular surface and tear function tests. Methods: A total of 70 women in the postmenopausal period were enrolled in the study. The groups consisted of 16 women who were not on HRT (group 1), 29 women who were on HRT with tibolone (group 2) and 25 women who received estradiol plus medroxyprogesterone acetate treatment (group 3). All patients underwent tear film break-up time (TFBUT), Schirmer’s test and conjunctiva cytology at the time of enrollment and at 6 months’ follow-up. Results: Patients in group 2 showed improved Schirmer’s test and TFBUT results (p < 0.001); however, no significant changes occurred in group 1 and group 3 patients (p > 0.05). Conjunctival cytology scores did not differ at the time of enrollment and at 6 months’ follow-up in all groups. Conclusions: This is the first comparative clinical study on the effects of tibolone and estradiol plus medroxyprogesterone acetate on ocular surface and tear function tests. HRT with tibolone seems to improve tear function tests in postmenopausal women.
ABSTRACT.Purpose: To investigate whether moderate cigarette smoking has any effects on the central visual field. Methods: This study included 30 healthy, moderate cigarette smokers (10-20 cigarettes per day for at least the past 5 years) and 22 healthy non-smokers. After two training test sessions, all individuals underwent computerized visual field examinations (Humphrey 30-2 Full Threshold Test) with both white-on-white (W-W) perimetry and blue-on-yellow (B-Y) perimetry. One eye of each subject with reliable visual field test results was evaluated. The foveal threshold, mean deviation (MD), pattern standard deviation (PSD), short-term fluctuation (SF), corrected pattern standard deviation (CPSD), glaucoma hemifield test (GHT) and number of significantly depressed points deviating at p < 5%, p < 2%, p < 1% and p < 0.5% on the pattern deviation probability map of the smokers were compared with those of the non-smokers. Results: When the results of W-W perimetry were analysed, the smokers were found to have significantly lower foveal thresholds (p ¼ 0.001) and mean retinal sensitivity (p ¼ 0.02), and higher PSD (p ¼ 0.002) and CPSD (p ¼ 0.01) than the non-smokers. Short-term fluctuation was similar in both groups (p ¼ 0.55). The number of significantly depressed points deviating at p < 5%, p < 2% and p < 1% on the pattern deviation probability map was similar for both groups (p > 0.05). The number of depressed points deviating at p < 0.5% on the pattern deviation probability map was higher for the smokers than for the non-smokers (p ¼ 0.03). The results of B-Y perimetry showed the smokers to have a significantly lower foveal threshold than the non-smokers (p ¼ 0.03). However, there were no significant differences in the global indices of the two groups (p > 0.05). The number of significantly depressed points deviating at p < 5%, p < 2%, p < 1% and p < 0.5% on the pattern deviation probability map was similar in both groups (p > 0.05). No significant difference in GHT was determined with either perimetry for the smokers compared with the non-smokers (p > 0.05). Conclusion: This study suggests that moderate cigarette smoking is associated with both diffuse and localized reductions in retinal sensitivity with W-W perimetry. Only reduction in the foveal threshold was observed with B-Y perimetry, with no hints of diffuse and localized reductions.
The purpose of this study was to report recurrent optic disc and retinal vasculitis in a patient with drug-induced urticarial vasculitis. Complete ophthalmological examination including fluorescein angiography and visual field examination were done. A 53-year-old woman with recurrent painful urticarial skin lesions following trimethoprim sulfamethoxazole usage had the clinical and histopathological diagnosis of urticarial vasculitis. Two years after cutaneous manifestations, she began to notice visual disturbances in both eyes that recurred at 1-year intervals. Her ophthalmological findings were consistent with recurrent vasculitis of the optic nerve and retina. Treatment with high-dose corticosteroids and hydroxychloroquine resulted in the resolution of cutaneous and ocular manifestations. This patient demonstrates that recurrent occlusive vasculitis of the optic nerve and retina can occur in this rare disease. These patients should be examined periodically by ophthalmologists.
This study found that a single drop of latanoprost significantly reduces intraocular pressure 8 h after dosing. However, it does not have any short-term effects on the retrobulbar haemodynamics in ocular hypertensive eyes.
