To evaulate the closure and recurrence rate of laser treatment for juxtafoveal and extrafoveal CNV with well-defined boundary, we studied 15 eyes of 15 patients that could be followed up for at least 1 year. The follow-up ranged form 12 to 31 months(mean, 17.1 months). Three and six weeks after laser treatment, all neovascularization was obliterated. Eight months, after laserphotocoagulation was obliterated. Eight months, after laser photocoagulation there was one recurrence in juxtafoveal CNV. In7 of 10 laser-treated eyes in classic, extrafoveal CNV, visual or more in three eyes. Of 5 laser-treated eyes in classic, juxtafoveal CNV, visual acuity had changed by no more than 2 lines in 3 eyes and decreased by 2 or more lines in 2 eyes. The short-term results of laser treatment for classic CNV were good, but long-term evaluation is required.

The purpose of this study was to evaluate the effect of age on the ratio of pulp cavity/tooth width (P/T ratio) in healthy cats. The dental radiographs of 32 cats (16 males and 16 females) were generated with a digital dental X-ray unit with the animals under general anesthesia. Standardized measurement of the canine teeth was performed by drawing a line on the radiograph perpendicular to the cementoenamel junction (CEJ) of the tooth. There was an inversely proportional correlation between chronological age and the P/T ratio. Moreover, a strong Pearson squared correlation (gamma2 = 0.92) was identified by the curved regression model. No significant differences in the P/T ratio based on gender or breed were found. These results suggest that determination of age by P/T ratio could be clinically useful for estimating the chronological age of cats.
