ABSTRACT
We report an anterior megalophthalmos case with decreased corneal thickness and show the findings using Scheimpflug imaging. A 25-year-old male was diagnosed with anterior megalophthalmos. In both eyes, enlarged corneal length was measured. Beside a comparatively good visual acuity, a thin but clear cornea, a fairly deep anterior chamber, and central lens opacity were found. Scheimpflug images were taken using Pentacam HR. Scheimpflug-based imaging can provide us new data at the examination of this syndrome affecting the whole anterior segment.

Anterior megalophthalmos, a rare hereditary disorder, is macrocornea (horizontal corneal diameter more than 13 mm) in association with enlarged lens-iris diaphragm and ciliary ring. One of the major challenging issues in the cataract surgery of these patients is preventing intraocular lens (IOL) malposition, because of probable large capsular bag. Several approaches have been selected by previous surgeons, such as, custom-made anterior chamber IOLs. In this study, we show a normal capsular bag diameter despite ciliary ring enlargement, with application of ultrasound biomicroscopy (UMB). We suggest that in cases of anterior megalophthalmos without phacodonesis, UBM could measure the actual size of the capsular bag and obviate the need for further procedures.

We report the case of a 16-year-old woman with microspherophakia and secondary open angle glaucoma. The patient presented with a membrane dividing the anterior chamber into two segments without edema or Descemet's membrane detachment. Slit lamp biomicroscopy, Pentacam, and specular microscopy images were obtained. Double anterior chamber is primarily found in patients with anterior chamber anomalies when there is no history of surgery or trauma.

Os autores descrevem associação rara bilateral de coloboma da íris, coróide, retina e cabeça do nervo óptico, microcórnea e deficiência de clivagem de câmara anterior. Fazem também uma abordagem quanto à embriologia e à dificuldade de identificar se a causa da queda contínua e insidiosa da visão é devida ao próprio coloboma ou a outra doença associada, como o glaucoma. Os exames subsidiários disponíveis como campo visual, fundoscopia e tonometria, são de pouca confiabilidade devido ao nistagmo e à baixa acuidade visual.

Objetivo: avaliar a frequência de complicaçöes decorrentes do uso intra-operatório de mitomicina C em trabeculectomias. Materiais e métodos: foram analisados 76 olhos submetidos à cirurgia filtrante com Mitomicina C, notando-se diagnóstico, indicaçäo para seu uso, medidas de pressäo intraocular, número de medicaçöes antiglaucomatosas e complicaçöes no período pós-operatório. Resultados: esta série mostrou incidência de 25 por cento de câmara anterior rasa, 18,4 por cento de hiperfiltraçäo, 10,5 por cento de catarata e 9,2 p/cento de descolamento de coróide. Conclusöes: o presente estudo sugere que a mitomicina C deve ser utilizada com bastante critério e cautela pelo oftalmologista, tendo em vista as complicaçöes potencialmente graves que podem dela advir

El síndrome iridocorneal endotelial incluye la atrofia esencial del iris, el nevo del iris o síndrome de Cogan-Reese y el síndrome de Chandler. Esta patología se caracteriza por anormalidades en la córnea, ángulo de la cámara anterior e iris. En síndrome de Chandler existe una membrana que crece hacia el ángulo produciendo alteraciones en el iris y glaucoma secundario entre otras. El pronóstico de esta enfermedad es incierto aun con tratamiento quirúrgico. Presentamos el caso clínico de una paciente con este síndrome y su evolución a 4 meses después del tratamiento

A aniridia é uma síndrome frequentemente associada a defeitos oculares múltiplos que podem acometer íris, córnea, cristalino, câmara anterior, nervo óptico e retina, além de alteraçöes sistêmicas como Tumor de Wilms, retardo mental, anomalias gênito-urinárias em uma mesma família, onde foram acometidos a mäe, duas filhas e um filho. A herança provável foi autossômica dominante e o estudo do cariótipo mostrou-se normal. O tecido iriano hipolásico foi de difícil visualizaçäo, observado apenas à gonioscopia. Apareceram alteraçöes corneanas como cicatrizes centrais e neovasos periféricos, como um "pannus" em toda a circunferência. Observaram-se grande incdência de catarata e coloboma de cristalino. A hipoplasia de papila ocorreu em todos os casos estudados

A 21-year-old woman had left iridogoniodysgenesis without any other associated ocular or systemic abnormalities. A thick band of anterior iris stroma extended forward and formed an adhesion with Schwalbe's ring across the anterior chamber angle at 3 o'clock position in the left eye. Each eye had 20/20 [6/6] visual acuity without glasses. There was no distortion of pupil, or any associated glaucoma

Descreve-se o caso de dois irmäos portadores de disgenesia da câmara anterior do olho associada a glaucoma, cujos genitores eram normais e consangüíneos. Um raro padräo de herança autossômico recessivo parece ser o mais provável neste caso

A 17 year old young man, presented with a dark brown mass in the anterior chamber of the right eye. The vision, tension and pupillary reactions were normal. The mass proved to be cystic on biomicroscopic examination. The cyst was treated by argon laser photocoagulation. The case was followed up for 9 months without untoward reactions

The results of the use of mannitol as a line of treatment for delayed anterior chember formation after intra-ocular operations are discussed. Thirty five cases of delayed chamber formation had been met with at the Ophthalmic section of Am Shams University Hospitals, during the last two years. Their aetiology as regards wound leakage, choroidal detachment and pupillary block is described. Thirty two cases [due to the last two Causes], were treated by the use of mannitol 25% by the slow intra venous drip. The pharmacological properties of mannitol, and its possible mode of action on the eye as regards aqueous f ormation and vitreous shrinkage is discussed
