[Photocoagulation of senile macular degeneration. (Critical analysis of the results obtained in 66 cases)].

The article is a critical study of visual results obtained by means of photocoagulation in 66 cases of senile macular degeneration with a follow up from 3 months up to 45 months. The author believes that an improvement of the visual acuity of 0,1 is not a reliable criteria for evaluation of the results. She takes as true good results only the cases in which reading is possible after treatment (visual acuity greater than or equal to 0,7 Parinaud 3). Using that criteria the percentage of true sucess is only of 32,5 p. 100 for the cases treated since over one year. That percentage is low but it seems enough to justify the treatment since only 3,4 p. 100 of the non treated cases keep usefull visual acuity after one year. Besides, review of the causes of sucess and failures leads to feel that the results should be improved in the future by an earlier treatment, a better selection of the indications and a more accurate technique.

Alpha 1-antitrypsin in amniotic fluid.

Amniotic fluid a1-antitrypsin values were determined by radial immunodiffusion of 317 samples obtained between the 10th and 43rd weeks of gestation in normal pregnant patients and those with complications. Serial determinations of a1-antitrypsin values revealed that in normal patients values decreased as pregnancy advanced while values increased as pregnancy advanced in cases in which there was severe Rh-alloimmunization and hydramnios. A wide range of values was observed for each week of gestation. Although there was a definite tendency for values to decrease as pregnancy advanced (60.8 mg/100 ml before 30 weeks and 17.9/100 ml after 40 weeks); the method must be regarded as unreliable for determining fetal maturity in clinical practice. In the case of newborn infants with hyaline membrane disease, no decrease in amniotic fluid a1-antitrypsin values has been found.
