Childhood glaucoma is a potentially blinding disease and poses crucial challenges in both diagnosis and management. We report a rare case of secondary glaucoma associated with nonacquired ocular anomalies in a 3-month infant with a family history of pigmentary glaucoma (PG) in two generations presenting as bilateral buphthalmos associated with ectropion uveae, microspherophakia, and high myopia. The child was successfully managed by combined trabeculotomy and MMC-augmented trabeculectomy with stabilized IOP at 12 months follow-up.

Congenital ectropion uveae (CEU) is a rare, nonprogressive condition characterized by the presence of posterior pigment epithelium of iris on the anterior surface of the iris. Reported patients were mostly in the second decade, with juvenile open-angle glaucoma (JOAG) and there are only two reports of CEU in infancy., Neonatal onset ectropion uveae (N-CEU) is a distinct entity, which is clinically different from the late onset classical CEU. Buphthalmos associated with N-CEU and anterior segment anomalies should alert the treating clinician regarding the severity of the disease course warranting multiple surgical intervention and poor visual prognosis.
| Case Report|| |
A 3-month-old infant, first born male child of nonconsanguineous marriage, was referred as a case of congenital glaucoma for evaluation. There was a family history of Pigmentary glaucoma (PG) in father and paternal grandmother [Table 1] and [Figure 1]a, [Figure 1]b, [Figure 1]c, [Figure 1]d. Mother noticed watering, increasing eyeball size and photophobia in both eyes (OU) since 15 days after birth and consulted outside. The child was diagnosed to have congenital glaucoma elsewhere two months back, and treated with Dorzolamide hydrochloride (2%) eye drops two times a day in both eyes (OU). Systemic examination was unremarkable and child attained normal milestones till date. On torchlight examination, bilateral buphthalmos with corneal edema and photophobia was observed [Figure 2]a.

On examination under anesthesia (EUA) using Sevoflurane, bilateral megalocornea with increased corneal diameter (horizontal/vertical Right eye (OD) -15/14.5 mm, Left eye (OS)-14.5/14 mm) and corneal stromal edema [Figure 2]b more in OD than OS was observed. Furthermore, the child had multiple areas of iris stromal thinning and 3600 CEU in OU. Intraocular pressure (IOP) by Perkins tonometry (Haag-Streit, Koeniz, Switzerland) was 32 mmHg OD & 36 mm Hg OS. Gonioscopy & Fundus evaluation OU was hazy due to corneal edema. Axial lengths (AL) were 22.32 mm OD, 22.05 mm OS. Refraction and keratometry was not done due to severe corneal edema. The child was diagnosed as secondary glaucoma associated with nonacquired ocular anomaly (CEU) according to CGRN (Childhood Glaucoma Research Network) classification. Subsequently, the child underwent simultaneous combined Trabeculotomy and Mitomycin-C (MMC) augmented Trabeculectomy OU [Figure 2]c and [Figure 2]d. Postoperative period was uneventful and child was advised tapering doses of combination of steroid antibiotic (0.3% Tobramycin +0.1% Dexamethasone) eyeointment along with cycloplegics (1% Atropine ointment) for a period of 8 weeks.
At 12-week follow-up, child was examined under EUA which revealed OU megalocornea (Horizontal/Vertical- 13.5/13 mm OD, Horizontal/Vertical-13/12.5 mm OS), mild central corneal haze, very deep anterior chamber (AC), avascular bleb [Figure 2]e and [Figure 2]f, updrawn & dilated pupil, 3600 CEU, microspherophakic lens with complete visibility of lens equator and pigments over posterior capsule along the zonular attachment [Figure 3]a and [Figure 3]b. IOP was 20 mmHg OD, 16 mmHg OS and fundus OU showed large myopic disc with CDR-0.65 OD & CDR-0.6 OS. Peripheral retinal evaluation excluded pigmentary retinopathy. Refraction values showed -19D OD & -18D OS. Ocular biometry (Micro-Medical-Devices Palmscan AK2000 Pro-A scan & Keratometer) showed the following values -AL 21.89 mm OD, 21.67 mm OS, AC depth- 4.12 mm OD, 4.02 mm OS, anteroposterior lens thickness (LT)- 4.85 mm OD, 4.7 mm OS and keratometry (K1/K2) - 40.71/42.88 OD, 40.66/42.13 OS. Gonioscopy OU revealed trabeculodysgenesis with anterior insertion of iris. Hence, the clinical diagnosis was revised as secondary glaucoma associated with N-CEU and microspherophakia. The child was advised glasses only with (-18D) and periodically review every 3 months to exclude progressive glaucomatous damage.

| Discussion|| |
CEU is the failure of primordial endothelium to completely regress or there may be a late developmental arrest of neural crest tissue in utero., CEU was first described by Wicherkiewicz B in 1891., Dowling et al. described unilateral CEU, iris stromal hypoplasia, anterior insertion of the iris root, and glaucoma, with no underlying systemic abnormalities. In the case series reported by Ritch et al. which included 8 patients with CEU, seven of 8 patients developed glaucoma and the systemic associations were Neurofibromatosis, Prader–Willi syndrome, Rieger anomaly, and facial hemihypertrophy, suggesting the possibility of a neural crest cell disorder. Harasymowycz et al. reported glaucoma in a 3-year-old child, whose histopathologic examination from the iridectomy site showed a fibrovascular membrane covering the anterior surface of the iris stroma.
The extent of ectropion uveae observed in our child was less extensive than the previously reported cases. A recent case series report by Kaushik et al. described Neonatal-onset ectropian uveae (N-CEU) as a phenotypically and genotypically distinct entity from the typical CEU described in literature so far. 13 of 16 (81.2%) eyes with PCG had a good outcome compared to 6 of 20 (30%) N-CEU eyes.
The described case report with a history of PG in two generations highlights a rare presentation of secondary childhood glaucoma as infantile buphthalmos, N-CEU, angle dysgenesis, microspherophakia and high myopia. The updrawn pupil in OS and pigment dispersion over the posterior capsule along the zonular attachment observed during follow-up visits are probably as a consequence of surgery related pigment release from the uveal tissues.
The probable differential diagnosis of this clinical entity is microspherophakia associated with anterior segment dysgenesis. Childhood onset anterior segment dygenesis has been sparsely reported in literature.,, Recently, Shakrawal et al. described a 13-year boy with bilateral multiple anterior segment anomalies like prominent Schwalbe's line, shallow anterior chamber, iris stromal thinning, ectropion uveae, corectopia, microspherophakia and left eye had posterior synechiae with iridocorneal adhesions. Though genetic testing for CYP1B1, PAX6, FOXC1, or PITX2 was suggested for our child, parents declined.
Childhood glaucoma associated with multiple developmental ocular abnormalities are usually refractory to medical therapy necessitating more than one surgical intervention for controlling IOP. Hence, this child need close monitoring of glaucomatous progression to avoid glaucoma related blindness.
| Conclusion|| |
This is a rare case of secondary glaucoma associated with non-acquired ocular anomalies in a 3-month infant with a family history of pigmentary glaucoma in two generations, presenting as bilateral buphthalmos associated with ectropion uveae, microspherophakia, and high myopia.
