ABSTRACT
PURPOSE: To compare the surgical conditions and complications and patient and surgeon satisfaction in cataract surgery by phacoemulsification under topical anesthesia (TA) versus sub-Tenon block (STB). METHODS: Prospective randomized comparative blind study, without placebo control. Patient satisfaction evaluated by the Iowa Satisfaction with Anesthesia Scale (ISAS). RESULTS: The authors prospectively enrolled 59 patients (61% female) in the study, who were randomized into groups: 26 in the TA group and 33 in the STB. There was no statistically significant difference between the groups in terms of age, sex, waiting time for surgery, ASA (American Society of Anesthesiologists) state, eye laterality, cataract density, pupillary dilation, or surgery duration, but patient collaboration was better in the STB group. We found a mean 2.2 mmHg post-anesthetic rise in intraocular pressure in the STB group, with normalization at 24 hours, and no rise in the TA group. Subconjunctival hemorrhage and chemosis were more prevalent in the STB group, and the improvement of visual acuity was similar in both groups. Subjective satisfaction with the anesthetic technique, both for the surgeon and for the patient, was more elevated in the STB group. The final ISAS scores were 1.87 in the TA group and 2.71 in the STB (p<0.005). CONCLUSIONS: The data indicate that more significant anesthesia and analgesia was achieved with the STB, leading to more favorable surgical conditions and enhanced patient and surgeon satisfaction.

PURPOSE: To report the prevalence of ocular abnormalities in a group of Portuguese children with a complete fetal alcohol syndrome (FAS). METHODS: Complete ophthalmologic examination in a sample of consecutive children with FAS. Ocular fundus photography was carried out on the cooperative FAS children and on 25 reference children. Ocular fundus anomalies were recorded by the observation of ocular fundus photography. The ratio between the distance of the center of the disc to the fovea and optic disc diameter (DM/DD) was determined. Small optic disc was defined as a DM/DD ratio above mean control group +1 SD. RESULTS: The authors studied 32 children with FAS (mean age: 9 +/- 5 years; 72% boys). The mean corrected visual acuity (VA) was 0.8 +/- 0.2. Refraction ranged from -23.00 to +6.50 spherical equivalent. Ocular findings included short horizontal palpebral fissure (81% of children), strabismus (28% of children), epicanthus (27% of eyes), blepharoptosis (16% of eyes), telecanthus (13% of children), nystagmus (1 child), and cataract (1 eye). Ocular fundus photography analysis showed retinal vessel tortuosity in 30% of the eyes and optic disc hypoplasia in 25%. The mean DM/DD for the control and FAS groups was 2.72 +/- 0.20 and 2.89 +/- 0.25 (p=0.001). Forty percent of the eyes of FAS children had small optic discs. CONCLUSIONS: The most common ocular findings were anomalies of retinal fundus and minor changes in the outer region of the eyes. The authors noted better VA and less severity of disease than others, which might be due to a different selection of patients, different pattern of alcohol consumption, or genetic differences.
