At the end of surgery, tables were assigned to each patient indicating the degree of pain(0-3) felt during the operation.RESULTS: Thirty-two percent of patients in group 1 declared to have not felt any pain against the 77% of patients in group 2. Fifty-nine percent of patients in group 1 complained about only a slight discomfort against 20% of group 2 patients. Only a small percentage of patients in group 1(5%) admitted severe pain, while no patient in group 2 admitted severe pain. Four patients of group 2 reported an episode of transient amaurosis, lasting several hours after surgery.CONCLUSION: Intracameral administration of lidocaine is a simple and secure method able to increase the analgesia during the cataract surgery, eliminating the discomfort and increasing also the cooperation of the patients during the steps of manipulation.展开更多

The parameters taken into account at baseline（T0） and after 30 d（T1） of therapy were: conjunctival hyperemia, lacrimal function tests [Schirmer I test and break up time（BUT）] and intraocular pressure（IOP）.RESULTS: Conjunctival hyperemia showed a substantial improvement in both treated groups（P<0.001） but not among controls. Similarly, lacrimal function tests displayed an improvement of Schirmer I test in both treated groups（P<0.05） and an extension of BUT only in the group treated with 0.1% TSA（P<0.05）. The IOP increase was statistically significant only in those patients treated with 0.1% TCB（P<0.001）.CONCLUSION: The 0.1% TSA has proved to be an effective anti-inflammatory treatment of blepharoconjunctivitis affecting glaucoma patients on therapy with TPAs, leading to a sizeable decrease of inflammation as well as both quantitative and qualitative improvement of tear film. Furthermore, differently from 0.1% TCB, it does not induce any significant IOP increase.展开更多

The observational study was performed by using gonioscopy for the selection and follow-up of 1165 treated eyes and exploiting Shaffer-Etienne gonioscopic classification as a quality/quantity test of the angle recession.·METHODS: Between September 2000 and July 2012,586 patients were selected at the Outpatients’ Ophthalmological Clinic of the Policlinico Umberto I of Rome in order to undergo Nd: Yag laser iridotomy. A Goldmann type contact lens, Q-switched mode, 2-3defocus, and 7-9 m J intensity with 2-3 impulse discharges were used for surgery.·RESULTS: From as early as the first week, a whole360° angle widening were evident in the patients, thus showing the success of Nd:Yag laser iridotomy in solving relative pupil block. The angle remained narrow by 270° in 14 eyes only, despite repetitions of further treatment with laser iridotomy in a different part of the iris, twice in 10 eyes and three times in 4 eyes.·CONCLUSION: Nd:Yag laser iridotomy revealed itself as being a safe and effective treatment in widening those critical Shaffer-Etienne grade 1 and 2 potentially occludable angles.展开更多
