Glaucoma secondary to Peters anomaly is an important factor affecting visual prognosis, but there are few reports on the condition. This study aimed to investigate the characteristics of glaucoma associated with Peters anomaly and glaucoma surgery outcomes. This retrospective study included 31 eyes of 20 patients with Peters anomaly. Peters anomaly was classified into three stages: Stage 1, with a posterior corneal defect only; Stage 2, a corneal defect with iridocorneal adhesion; and Stage 3, a corneal defect with lens abnormalities. The associations between glaucoma and anterior segment dysgenesis severity, visual prognosis, and glaucoma surgery outcomes were analyzed. Sixteen eyes of ten patients developed glaucoma. Stage 1 Peters anomaly had no glaucoma, 52% of Stage 2 had glaucoma, and 75% of Stage 3 had glaucoma. Of the 16 eyes with glaucoma, 11 underwent surgery. Eight of these eleven eyes achieved intraocular pressure (IOP) control. Five of the nine eyes that underwent trabeculotomy (TLO) succeeded, and none had corneal staphyloma. Three of the four eyes for which TLO was ineffective had corneal staphyloma (p = 0.0331). Patients with Peters anomaly are more likely to develop glaucoma as anterior segment dysgenesis progresses, and the effect of TLO is limited if corneal staphyloma is present.

BACKGROUND: PITX3 has been reported to be associated with congenital cataracts, anterior segment mesenchymal dysgenesis, Peters\' anomaly, and microphthalmia. In this case, an infant with unilateral buphthalmos, corneal staphyloma and corneal fistula carrying a variant in PITX3 was reported.
METHODS: We describe a 4-month-old female infant who was referred to our Eye Clinic because of gradual enlargement of the eyeball in the right eye and whitish opacity in both eyes. Buphthalmos with long axial length (22.04 mm), macrocornea with diffuse corneal oedema and opacity (14.50 mm*14.50 mm) and high intraocular pressure (23.78 mmHg) were detected in the right eye. Microphthalmia with short axial length (16.23 mm), microcornea with diffuse corneal oedema and opacity (7.50 mm*6.50 mm) were detected in the left eye. A 360° trabeculotomy was performed for the right eye. However, corneal staphyloma and corneal fistula in the right eye were detected 6 months after the surgery. A variant in exon 4 of PITX3 (c.640_656dup (p. Gly220Profs*95)) was identified in the proband but was not detected in her healthy parents.
CONCLUSIONS: A novel phenotype characterized by unilateral buphthalmos, corneal staphyloma and corneal fistula in an infant were reported to be associated with PITX3 in our study. Our study expands the scope of the clinical heterogeneity of PITX3 variants. It also improves our understanding and increases the attention given to patients with PITX3 variants.

Ocular trauma occurring in children often leads to visual impairment or blindness when it is not properly managed. This often occurs in underdeveloped regions with difficult access to professional care at local health facilities. We report a case of post-trauma corneal staphyloma in an underdeveloped region of eastern Indonesia to illustrate the importance of proper management of ocular trauma in areas lacking such expertise and where patients have difficulty accessing even basic health care. During a community health outreach in Southwest Sumba, eastern Indonesia in May 2017, a 7-year-old boy presented with white protrusion of the left eye of 3 years\' duration following an event of sharp trauma. The patient lived in an inaccessible and impoverished area. Upon contemporary examination, visual acuity of the left eye was 1/300 while that of the right eye was 6/6. Anterior examination revealed corneal staphyloma of the left eye, and its posterior segment could not be evaluated. The patient was transported to an eye care center in Jakarta, receiving a stock prosthesis implant while awaiting a corneal evisceration procedure with dermofat graft. Ocular trauma is one of the most common causes of visual impairment in children. This case illustrates the consequences of inadequate post-trauma management and the importance of prevention of infection.

Abstract Background: A microdeletion in the chromosome 22q11.2 (DiGeorge or velocardiofacial syndrome) is the most common human deletion syndrome. Patients with 22q11.2 deletion may have a wide range of ocular findings but severe ocular involvement is uncommon. Here, we describe a 2-year-old boy who had growth retardation, developmental delay, right renal agenesis, ventricular septal defect and severe bilateral ocular anomalies.
METHODS: The systemic and ocular findings and cranial magnetic resonance imaging study results were reviewed. Fluorescence in situ hybridization analysis was performed on his peripheral blood.
RESULTS: The patient presented with the oculodigital sign. On examination, he had severe right microphthalmia with no light perception and his left eye could not fix and follow. The left eye had anterior segment dysgenesis, mild sclerocornea, corneal staphyloma and congenital aphakia. Systemic findings included growth deficiency, microcephaly, micrognathia, ventricular septal defect, atrial septal defect and right renal agenesis. Fluorescence in situ hybridization analysis of this patient was significant for a heterozygous deletion covering DiGeorge critical region 2 and spanning a 250 kb region in the 22q11.2 locus.
CONCLUSIONS: The 22q11.2 deletion syndrome may be associated with severe bilateral ocular malformations including microphthalmia, sclerocornea, corneal staphyloma, anterior segment dysgenesis and congenital aphakia. Corneal staphyloma might have resulted from the oculodigital phenomenon or increased intraocular pressure.
