Abstract

Aim: To evaluate the effect of intraocular pressure (IOP) on central corneal thickness (CCT), horizontal corneal diameter (HCD), axial length (AL) in patients with primary congenital glaucoma (PCG) after antiglaucoma surgery.
Materials and Methods: In this hospital based interventional study 36 patients (66 eyes) of PCG who underwent antiglaucoma surgery were included in the study. For each patient visual acuity, anterior and posterior segment examination, IOP, AL, CCT, HCD and refraction (in clear media) were recorded pre and post operatively (3 weeks, 3 months, 6 months). B scan ultrasonography was done to measure AL and to rule out posterior segment pathology. Surgery was performed by a glaucoma expert (by a single surgeon).
Results: Bilateral involvement was present in 83.33% with the most common symptom being photophobia and watering (30.56% each). The mean IOP, CCT, HCD, VCD and AL before surgery were 26.88+/-2.78 mmHg, 614.38+/-89.41 µ, 14.41+/-1.26mm, 13.19+/-1.46mm and 24.78+/-2.21mm and at 6 months were 13.85+/-1.93 mmHg, 548.56+/-63.13 µ, 14.62+/-0.49 mm, 13.34+/-1.10 mm and 25.73+/-1.36mm respectively. 59.1% of the patients had corneal clearing at 6 months.
Conclusion: Control of IOP affects various parameters of eye like CCT, HCD and AL. Early surgery is the definitive line of management for controlling IOP in PCG patients.
