Abstract
Primary congenital glaucoma is a vision-threatening disease, it needs a long life follow up, management aims to normalize the IOP to prevent complications including corneal opacification and glaucomatous optic atrophy.
PCG commonly presents bilaterally. The classical triad of symptoms is epiphora, photophobia and blepharospasm and the most common presenting sign is cloudy cornea
Surgical treatment in the mild form of congenital glaucoma is generally successful, no matter which procedure is chosen but in the moderate and severe forms combined trabeculotomy-trabeculectomy with adjunctive mitomycin C results in better IOP control.
Scheimpflug photography is one of the significant modalities that can image the anterior segment. It provides qualitative and quantitative analysis of corneal morphology allowing a noncontact method of estimating central corneal thickness (CCT) and intraocular pressure (IOP) providing three-dimensional image representations of the anterior segment which may be useful for screening narrow angles and detecting glaucoma risk.
The study was conducted on 44 eyes of 28 patients ageing from 5- 16 years that had undergone uneventful surgery for primary congenital glaucoma and 59 eyes of 31 age matched normal children enrolled as controls.
There was a male predominance in PCG cases (67.9% of cases) while females represented (32.1%).
The mean age at scan of the cases ranged from 5.30 to 16.90 years while the age at scan of the controls ranged from3.87 – 15.63.
The study reported the anatomical differences in cornea and anterior chamber between PCG and healthy eyes, PCG eyes were more likely to have larger corneal diameter and astigmatism with a thinner and flatter cornea, increased anterior chamber volume, depth and angle, assumed the alternation in eyes affected with PCG.
The study documented the correlations of demographic and clinical data with the scheimpflug parameters pre and postoperatively. High preoperative axial length was associated with larger anterior chamber volume and significantly flatter keratometry readings (K1, K2), explained by the emmetropization process. Reflecting the enlargement of the anterior segment of the eye with enlargement of the axial length.
Preoperative corneal diameter for PCG cases correlated negatively with keratometry readings and corneal thickness at the pupil center and at the thinnest location while it correlates positively with anterior chamber volume AC depth.
Lack of postoperative correlations with pentacam parameters the fact that adequate control of the condition can bring about stabilization of the ocular biometric characteristics.
