Evaluation of intraocular pressure in the first 24hours after micropulse laser trabeculoplasty in eyes with pseudoexfoliation glaucoma.

PURPOSE: To evaluate the immediate 24-hour effect on intraocular pressure (IOP) of a single session of micropulse laser trabeculoplasty (MLT) in patients with pseudoexfoliation glaucoma (PEXG). PATIENTS AND METHODS: In this single-center, one-arm, prospective study, patients with PEXG on prostaglandin analogue monotherapy with inadequate IOP control were treated with 360-degree 532nm MLT. Intraocular pressure was evaluated at 1, 4, 8, 12 and 24hours after MLT. Twenty-three eyes of eighteen patients (10 male, 8 female) were enrolled in the study. RESULTS: The mean age of the patients was 71.83±6.51 years, and the mean IOP prior to MLT was 20.61±1.8mmHg. The mean IOP was reduced by 2.17±3.31mmHg, 2.69±3.85mmHg, 0.87±3.02mmHg, 2.13±2.8mmHg and -0.87±3mmHg at 1, 4, 8 and 24hours after MLT, respectively. At 4 and 12hours after MLT, the mean IOP was statistically significantly lower compared to the pre-MLT IOP (P=0.043 and P=0.021 respectively). No eye experienced an IOP spike≥5mmHg during the first 24hours after MLT. CONCUSION: Treatment with MLT in PEXG eyes did not result in any significant, potentially dangerous IOP spikes during the first 24hours after MLT.

Α molecular epidemiological analysis of adenoviruses from excess conjunctivitis cases.

BACKGROUND: Τo perform a molecular epidemiological analysis of viral conjunctivitis among excess conjunctivitis cases recorded at the University Hospital of Patras, Greece, for the period March to June 2012. METHODS: A structured questionnaire containing demographic and clinical data was developed in order to collect retrospective data on the cases. Eye swab specimens were collected and molecular detection of adenoviruses was performed by nested PCR. Positive results were confirmed by sequencing. To determine the relatedness between the isolated sequences, a phylogenetic analysis was conducted. RESULTS: The epidemiological analysis (including retrospective data) included 231 conjunctivitis cases (47.1% male, and 52.8% female). Based on clinical features 205 of the cases were diagnosed of viral origin (46.3% male and 53.7% female), 4 of bacterial origin (50% male and 50% female) while 22 were undefined conjunctivitis. The outbreak excess cases (included 156 cases) affected all age groups regardless gender predilection. For the positive samples indicated that 29 samples (72.5%) were AdV17, and 5 (12.5%) as AdV54. CONCLUSIONS: Molecular analysis could define the cause of viral conjunctivitis, while epidemiological data contributed to the assessment of the risk factors and underlined possible preventive measures. This study is one of the very few on viral conjunctivitis in Greece. This outbreak underscores the need for a national surveillance system for acute infectious conjunctivitis outbreaks. The epidemiological as well as molecular investigation on HAdV ocular infections is rather absent in Greece, which has no surveillance system for viral conjunctivitis.
