ABSTRACT
Primary congenital glaucoma usually presents as enlarged and hazy cornea at birth or early childhood. The diagnosis is based on a thorough clinical examination under anesthesia. Most cases require surgical intervention as the definitive treatment. In very rare instances, primary congenital glaucoma may arrest and resolve spontaneously. We describe a case of spontaneously arrested and resolved primary congenital glaucoma in a 37‑year‑old male presenting with large cornea, Haab’s striae, and normal intraocular pressure in one eye. Such a case has not been previously described from the Indian subcontinent.
ABSTRACT
PURPOSE: To report a case that underwent successful centration of intraocular lens (IOL) and visual acuity improvement after cataract extraction in a megalocornic eye in our medical center. CASE SUMMARY: A 27-year-old man with bilateral megalocorneas came to our medical center. The patient had progressive loss of vision and floaters in both eyes for 3 months. His horizontal corneal diameter was approximately 14 mm in both eyes. The initial best corrected visual acuity was 0.02 in the right eye and 0.5 in the left eye. There was a white cataract and nuclear sclerotic cataract without lens luxation, respectively. The cataract was extracted from the patient's right eye after anterior continuous curvilinear capsulorrhexis (CCC), the preloaded custom IOL was inserted in the bag, and pars plana vitrectomy was performed. Two months later, after the cataract was extracted from the left eye, optic capture through a posterior capsule was attempted but converted to anterior capsule (reverse optic capture) because of the posterior CCC's radial tear, and pars plana vitrectomy performed. The IOL had a 6 mm optic and an overall length of 12.5 mm. The IOL in the right eye was decentrated inferiorly in the bag due to a large capsule diameter, but the IOL captured through the anterior capsule in the left eye had good centration. The best corrected visual acuity of both eyes improved to 0.8 without other complications.

En este artículo de revisión se pretende determinar los radios de curvatura que se pueden presentar en patologías y en alteraciones corneales de carácter hereditario, genético o iatrogénico, tanto en córneas planas y en córneas curvas como la esclerocórnea, microcórnea, megalocórnea, queratocono, queratoglobo, miopía de curvatura y otros. Se hizo una revisión bibliográfica de artículos con la información necesaria para identificar las alteraciones corneales más frecuentes que se pueden presentar en pacientes con córneas planas y córneas curvas diferentes a las queratometria, consideradas medidas promedio comprendidas entre 42,00 y 45,00 D. Se concluyó que los pacientes con córneas planas presentaban una refracción corneal entre 20,00 D y 41,50 D, siendo 32,25 D el promedio encontrado en la revisión; en las córneas curvas se encontraron refracciones corneales entre 51,00 D y 59,75 D, con un promedio de 55,50 D.
In this review there was tried to determine the curvature radius present in some pathologies and corneal diseases of hereditary, genetic or iatrogenic character, in flat corneas and steep corneas as esclerocornea, microcornea, megalocornea, Keratoconus, keratoglobus, curvature myopia and others. An article review was made to identify frequent corneal alterations that can be found in patients with flat and steeper curves different from corneal measures average between 42.00 and 45.00 D. It was concluded that in the patients with on flat corneas the corneal refraction was from 20.00 D to 41.50 D being the average value in the review 32.25 D; in steeper corneas, corneal refractions were from.

Introducción. El síndrome de Neuhauser es una rara enfermedad autosómica recesiva caracterizada por megalocórnea, retardo mental e hipotonía. Actualmente con delineación sindromática clínica, se ignora su mecanismo genético y carece de prueba diagnóstica específica. Caso clínico. Lactante de 18 meses con cara peculiar, hipotonía, síndrome convulsivo, afección en ambos ojos con glaucoma congénito y megalocórnea; presentando retardo mental y del desarrollo importantes. La evaluación dismorfológica permitió lograr el diagnóstico clínico. Conclusión. Sólo existen 36 casos reportados en la literatura, este reporte sería el primero publicado en Latinoamérica y ayudaría al enfoque clínico de pacientes con megalocórnea, retardo mental e hipotonía.
Introduction. Neuhauser syndrome is an extremely rare genetic recessive disorder characterized by megalocornea, mental and motor retardation and hypotonia. Nowadays, this syndrome has been clinically delineated but its genetic mechanism remains unknown, and there is no specific diagnostic test. Case report. An 18-month old female infant with characteristic facial dysmorphic traits; congenital glaucoma, megalocornea in both eyes and hypotonia; seizures, mental and motor retardation. Dysmorphologic evaluation allowed the clinical diagnosis. Conclusion. There are only 36 cases reported in the literature. This case is the first published in Latin America, and may be helpful in the clinical assessment of patients with megalocornea, mental and motor retardation and hypotonia.
ABSTRACT
Phakomatosis pigmentova.scularis is a disease complex with dermal melanocyto sis such as nevus of Ota, nevus of Ito, or Mongolian spots and extensive hemangiomatous change such as nevus flammeus, which are associated with systemic organ involvement. We report a 23-year-old female, who showed bilateral nevus of Ota and nevus of Ito with widespread nevus flammeus and Mongolian spots since birth. She was also associated with megalocornea due to congenitol glaucoma and cataract.
