Abstract :

Purpose: To ascertain parameters associated with visual outcome in congenital glaucoma. Methodology: A cross sectional evaluation of 63 consecutive patients having congenital glaucoma was performed. Targetâ?? IOP was maintained at <15 mmHg over at least 5 years. The parameters analysed were IOP, CDR, cornea, lens, axial length, refractive errors, perimetry and orthoptic status. Results: The mean age at first surgery was 16.84?±25.62 months. Mean IOP over 5 years in was 12.55?±2.23 mm of Hg. Best corrected visual acuity in Primary congenital glaucoma, PCG,eyes was 0.5065?±0.43081 and Congenital glaucoma with other ocular anomalies, CGA, had BCVA of 0.64328?±0.67058 (p=0.88). Forty one patients, 65.08% had a BCVA of â?¥6/18. Only 5 patients, 7.9% had a BCVA of <3/60. Patients having BCVA of â?¥6/18 had a CDR of 0.54?±0.17 and in patients with BCVA of <6/18 it was 0.76?±0.15, (p=0.0001). The mean axial length in the PCG group was 25.03?±2.6 mm and in CGA group it was 23.9?±2.3 mm (p=0.07). Haabâ??s striae were noted in 44.8%, present between 3 mm and 5 mm from the optical axis, they significantly correlated poor vision. PCG detected at â?¤1 month of age and those having a baseline IOP of >30 mm Hg showed greater perimetric damage. 17.5% had corneal opacification and 33.3% had cataract. Conclusion: With an IOP control of â?¤15 mm of Hg, cataract, corneal abnormalities, high myopia and a large cup disc ratio at baseline were commonly associated with vision loss in congenital glaucoma.
