Fear of Blindness in Patients Undergoing Cataract Surgery.

BACKGROUND: Fear is a negative emotion induced by the threat of danger, pain and harm. Cataract surgery is one of the most performed surgeries in the world. The aim of this study was to investigate and analyze the predominant fears in patients undergoing cataract surgery. SUBJECTS AND METHODS: In this cross-sectional study 152 patients were examined. Self-designed questionnaires to examine emotions of the fear, anxiety, nervousness frequency gratitude was used and insecurity immediately before cataract surgery. We also examined what the greatest fear during the cataract surgery was. The fear of blindness was compared with other life fears such as cancer, memory loss, AIDS, stroke and heart attack. The presence of fear was compared in patients having had previous cataract surgery with those undergoing their first cataract surgery. Including criteria were adults with senile cataract. Excluding criteria was ocular co-morbidity, psychiatric disorders, inability to read, deafness and surgery under general anesthesia. Completed questionnaires were analyzed. Pearson's chi-squared test was used. RESULTS: Fear was the most frequent emotion before cataract surgery, present in 60.5% patients. Fear of blindness was the greatest fear during cataract surgery in 55.3% of patients. There was no statistically significant difference in fear in patients having undergone their first cataract surgery and patients before their second cataract surgery (p<0.05). CONCLUSION: Fear is the predominant emotion before cataract surgery which is in correlation to the leading life fear - fear of blindness. Good preoperative preparation and a trusting doctor-patient relationship are important for reducing the fear of the procedure.

Human ophthalmomyiasis caused by Oestrus ovis-first report from Croatia and review on cases from Mediterranean countries.

Oestrus ovis is the most common cause of human ophthalmomyiasis. So far, majority of ophthalmomyiasis cases have been reported from Mediterranean countries, but not from Croatia. In current study, we present first two cases of human ophthalmomyiasis in Croatia, caused by O. ovis larvae. Reviewing a PubMed database, additional 259 cases of human ophthalmomyiasis in countries of Mediterranean basin have been reported. A total of 260 (99.62%) cases had external, while 1 (0.38%) had internal form of ocular myiasis. In all cases, O. ovis larvae were identified as the causative agent. O. ovis infestation is usually reported in shepherds and farmers although there is a high prevalence of infection in urban areas as well. Various climatic factors influence O. ovis larvipositional activity. Air temperature is the most important factor affecting O. ovis larviposition, while humidity, wind speed, and time of the day play only a moderate role. Most common symptoms of ophthalmomyiasis are irritation and redness, and in more than half of cases infestation is multiple. Ophthalmomyiasis interna is eye-compromising condition. Since there is reduced awareness among patients and medical professionals, the real number of ophthalmomyiasis cases is probably significantly higher than published. Global warming predisposes future increase of O. ovis prevalence in humans, which emphasizes the need for mandatory reporting and surveillance of disease.
