Abstract The aim of the work: To study the pathological macular changes in eyes with high myopia and to correlate clinical findings with findings of optical coherence tomography (OCT) and fluorescein angiography (FA). Material & Method : Patients with refraction greater than – 6D (spherical equivalent) were selected from those attending Mansoura University Ophthalmic Center Out-Patient Clinics from June 2005 through March 2006. Every patient was subjected to: History taking, measurement of visual acuity (UCVA & BCVA), refraction using autorefractmeters, posteriore segment examination axial length measurement, fluorescein angiography, optical coherence tomography of the macula. The studied eyes were divided into two groups (Group 1: Eyes with refraction equal to or less than -15D. Group 2: Eyes with refraction more than -15D). Results : Macular complications were detected in 55 eyes. Lacquer cracks ranked first among those complications followed by Fuchs spot, CNV, macular haemorrhage and macular hole, while retinoschisis was the least complication detected. Among group one; 53 eyes (71.6%) were free of macular complications compared to 21 eyes (28.4%) with macular complications while in group two; 13 eyes (27.7%) were free of macular complications compared to 34 eyes (72.3%) with macular complications. The following macular changes were detected in this study: Lacquer cracks (31.4%), choroidal neovessels (15.7%), haemorrhage (8.3%), macular hole (5%), Fuchs spot (16.5%)and retinoschisis (0.01%). Conclusion : The most common complication is lacquer cracks while the least one is retinoschisis. The incidence of CNV, macular holes and haemorrhage is not affected significantly by the axial length or the degree of myopia. |
