ABSTRACT
OBJECTIVE: The study was designed to investigate the potential effect of fish consumption on macular structure and function of healthy individuals. PATIENTS AND METHODS: The participants were Greek, who used to consume less than one portion of fish per week since their childhood. All participants underwent body mass index (BMI) measurements and ophthalmological examination. At their first examination, they were asked to consume at least 2 portions of fish per week over a period of 8 weeks, after which all the measurements were repeated. RESULTS: Eighteen healthy individuals (36 eyes) participated in this study. The central macular thickness was reduced, while the amplitudes in the foveal and parafoveal area were increased after the fish consumption. However, all measurements remained within the normal range at both visits. CONCLUSIONS: Regular fish consumption could enhance the structural and functional status of the macula.

PurposeTo evaluate risk factors for intraoperative floppy iris syndrome (IFIS) in patients undergoing phacoemulsification.MethodsParticipants in the study were 1274 consecutive patients, who underwent routine phacoemulsification cataract surgery. The following data were recorded and evaluated as possible risk factors: ophthalmological conditions, axial length of the eye, sociodemographic features, clinical data (hypertension and diabetes mellitus), medications being taken at the time of surgery, and duration of their intake. Cases were characterized intraoperatively as IFIS and non-IFIS. Univariate and multivariate logistic regression analysis were performed.ResultsIFIS was observed in 63/1274 eyes (4.9%, 95% CI: 3.9-6.7%). Current use of tamsulosin, alfuzosin, terazosin, benzodiazepines, quetiapine, and finasteride, as well as hypertension, were all independently associated with IFIS. Significant associations were noted for male sex, rivastigmine, and short axial length, which did not reach significance at the multivariate analysis. Duration of α-blockers intake was not found to be associated with IFIS.ConclusionApart from the well-established associations with α-blockers, this prospective study points to benzodiazepines, quetiapine, finasteride, and hypertension as potential risk factors for IFIS. Short axial length and rivastigmine were significantly associated with IFIS only at the univariate analysis.

BACKGROUND: Computer use can cause visual problems. The purpose of our study was to evaluate visual problems due to computer use in young adults. PATIENTS AND METHODS: Participants in our study were 87 adults, 48 male and 39 female, mean aged 31.3 years old (SD 7.6). All the participants completed a questionnaire regarding visual problems detected after computer use. RESULTS: The mean daily use of computers was 3.2 hours (SD 2.7). 65.5 % of the participants complained for dry eye, mainly after more than 2.5 hours of computer use. 32 persons (36.8 %) had a foreign body sensation in their eyes, while 15 participants (17.2 %) complained for blurred vision which caused difficulties in driving, after 3.25 hours of continuous computer use. 10.3 % of the participants sought medical advice for their problem. There was a statistically significant correlation between the frequency of visual problems and the duration of computer use (p = 0.021). 79.3 % of the participants use artificial tears during or after long use of computers, so as not to feel any ocular discomfort. CONCLUSIONS: The main symptom after computer use in young adults was dry eye. All visual problems associated with the duration of computer use. Artificial tears play an important role in the treatment of ocular discomfort after computer use.

PURPOSE: The benefit of cataract surgery in the general population concerning visual acuity and subjective visual function has been well established. However, a small proportion of patients are dissatisfied after cataract surgery. Our study aims to evaluate patients' dissatisfaction after phacoemulsification cataract surgery related to low visual function and to analyze the factors associated with this outcome. METHODS: 397 patients, who underwent uneventful phacoemulsification cataract surgery, participated in the study. All the participants completed a self-administered questionnaire which evaluated their visual function pre- and post-operatively. Best Corrected Visual Acuity (BCVA) was measured before and after cataract surgery and patients' contentment if they were satisfied or not with the result of the surgery was also recorded. RESULTS: Macular disease, diabetic retinopathy and glaucoma were the main factors limiting the final visual result after phacoemulsification cataract surgery. CONCLUSIONS: It is very important for the patients to be preoperatively fully aware of the presentation of the aforementioned fundus pathology and to be warned about the predicted visual outcome after cataract surgery.
