Structure-function correlation of juxtapapillary choroidal thickness with visual field analysis of patients suspected with glaucoma

Purpose@#To conduct an evaluation of juxtapapillary choroidal thickness of patients suspected with glaucoma obtained through spectral domain optical coherence tomography (SD-OCT) and correlate it with perimetry results.@*Methods@#Design: Cross-sectional Study. Population: 175 eyes diagnosed as “glaucoma suspect” had standard automated perimetry (SAP) to document the presence of functional glaucomatous damage using optimal near-point correction using the Humphrey Visual Field Analyzer II, 30-2 or 24-2 SITA-standard program. SD-OCT imaging of the retinal nerve fi ber layer (RNFL) was also done to look for structural glaucomatous damage and in using enhanced depth imaging of the optic nerve and the Cirrus caliper tool, choroidal thickness was measured at fi ve predetermined points temporal and nasal from the optic nerve. The population was classifi ed into two groups: Group 1 are those with structural or functional glaucomatous damage (n=68) and Group 2 were those without (n=107).@*Results@#One-Way Multivariate Analysis of Covariance was used in comparing the mean temporal and nasal choroidal thickness scores of the two groups. There are no statistical differences in terms of the mean temporal choroidal thickness (p=0.856) and mean nasal choroidal thickness (p=0.734) between patients with and without glaucomatous damage. The mean temporal and nasal choroidal thickness scores of the two groups at different juxtapapillary locations: 0 μm, 250 μm, 500 μm, 750 μm and 1000 μm away from the disc were also not statistically different.@*Conclusion@#Results show that from this present cohort of glaucoma suspect patients, juxtapapillary choroidal thickness is not correlated with structural and functional glaucomatous damage.

Wavefront-optimized treatment for myopia using Allegretto Wave Eye-Q excimer laser

Objective@#To evaluate the efficacy, predictability, and safety of LASIK surgery using the Allegretto Wave Eye-Q excimer laser.@*Methods @#Data of patients who underwent myopic LASIK were collected. The data consisted of pre- and postoperative refractions, uncorrected visual acuity (UCVA), best-corrected visual acuity (BCVA), and intraoperative treatment parameters. The main outcome measures were efficacy, predictability, and safety.@*Results@#One hundred eight eyes of 56 patients, 21 males and 35 females, mean age of 30.66 years, who underwent myopic LASIK in a tertiary hospital, were included in the study. The mean spherical error corrected was –5.22 ±2.56 D (median, –5.0 D). Postoperatively, all eyes achieved UCVA of 20/30 or better, with 92.6% achieving 20/20. Nearly 94% of patients maintained or gained 1 to 2 Snellen lines of BCVA postoperatively. One patient lost 2 Snellen line of BCVA. The mean postoperative manifest refraction spherical equivalent (MRSE) was –0.04 ± 0.26 D. The general refractive predictability was 93.52% within ± 0.5 D from the target refraction, while 76% of all patients had a postoperative MRSE of within ± 0.25 of the target.@*Conclusion@#Myopic LASIK performed using the Allegretto Wave Eye-Q excimer laser is safe and effective with high refractive predictability.
