After baseline CCT measurements of both eyes of 40 subjects were obtained using Scheimpflug system, a drop of preservative-free 2% fluorescein, was instilled in one eye and in other eye, one drop of normal saline (control). Measurements were repeated after 1, 2, 5, 10, 20, 30, 40, 50 and 60min (continuous assessment group). Twenty subjects had baseline CCT taken, then fluorescein was instilled in one eye and measurements were taken at lmin. Ten eyes had saline rinse after lmin and 10 other eyes did not, measurements were repeated at 2min (eye rinse group). RESULTS: The mean baseline CCT for continuous assessment group was 546.2±32.1um (range, 489.0-606.0), control eyes was 546.6~±30.7 um (range, 489.0-602.0). At lmin after fluorescein instillation, CCT significantly increased by 37.0±34.0um (P〈0.001), then decreased gradually, reaching baseline at 60min. CCT variations were not significant in control group (P〉0.05). For eye rinse group, CCT mean differences between baseline and 2min were 18.2um (95 % Ch -54.7 to 18.3) with rinse and 26.5um (95% CI: -62.9 to 9.9) without rinse; paired sample tests were not significant (P〉0.05). CONCLUSION: The presence of fluorescein increased CCT value to a clinically relevant level of 6.8%. Eye rinse did not significantly reduce the effect at 2min post fluorescein timepoint.展开更多

In each patient, the smar plug was inserted in the lower punctum of the right eye which was considered as study group 1 and silicone plug was inserted in the lower punctum of the left eye o the same patient which was considered as study group2. All patients were subjected to careful history taking and questionnaire for subjective assessment of severity of symptoms. Corneal sensitivity, corneal fluorescein rose bengal staining, Schirmer's I test, tear film break up time and conjunctival impression cytology were performed pre and 1, 3 and 6mo post plug insertion.RESULTS: A statistically significant improvement in subjective and objective manifestations occurred following treatment with both types of plugs(P 〈0.01)The thermosensitive plug caused significant overal improvement, decrease in frequency of application o tear substitutes and improvement of conjunctiva impression cytology parameters in the inserted side(P 〈0.01). Canaliculitis was reported in two eyes(4.4% following punctal occlusion using thermosensitive plug(study group 1). Spontaneous plug loss occurred in 21eyes(46.6%) in the silicone plug group(study group 2).CONCLUSION: Improvement of subjective and objective manifestations of aqueous deficient dry eye occurs following punctal plug occlusion. Thermosensitive plug has good patient's compliance with fewer complications and lower rates of loss compared to the silicone plug.展开更多

None had positive corneal fluorescein staining before surgery. Both eyes of each patient were analyzed, with one randomly allocated to receive medical hydro-gel eye patch, and the other to receive common adhesive tape as a control. Corneal injuries were evaluated by scoring fluorescein staining under a hand-held slit lamp immediately after surgery in postanesthesia care unit and 24 h thereafter. Patients’ discomforts were also evaluated.RESULTS: Twelve eyes(15.8%) in the hydro-gel patch group and 30 eyes(39.5%) in the adhesive tape group showed corneal injury immediately after surgery. The eyes protected with hydro-gel patch showed statistically less corneal fluorescein staining than the control group.Four eyes in hydro-gel patch group and 6 eyes in adhesive tape group suffered discomfort immediately after surgery without intergroup difference and all discomforts disappeared after 24h(P =0.257). No side effect was observed in hydro-gel patch group, while 5eyes had brow avulsion and 2 got skin itching in adhesive tape group.CONCLUSION: Corneal injury complication was morefrequent than we thought following general anesthesia.The medical hydro-gel eye patch can protect the occurrence of corneal injury following general anesthesia.展开更多
