Changes in the diabetic choroidal vasculature: scanning electron microscopy findings.

Scanning electron microscopy (SEM) was used to study vascular casts of 20 cadaver eyes according to our previously described technique. All eyes were taken from patients with long-standing diabetes mellitus type I. The SEM findings in the choroidal vessels included: increased tortuosity, dilation and narrowing, hypercellularity, vascular loop and microaneurysm formation, "drop-out" of choriocapillaries, and sinus-like structure formation between choroidal lobules. To our knowledge, these are the first SEM studies of the vascular casts performed on human cadaver eyes from diabetics.

Superior oblique overaction in patients with true Brown's syndrome.

The charts of all patients with the diagnosis of congenital Brown's syndrome seen between July 1983 and June 1984 were examined retrospectively. In the past, overaction of the ipsilateral superior oblique (OAISO) was felt by most authors to be absent or minimal. Our study revealed that separate observers consistently documented the presence of an OAISO in about one-fifth of the selected patients. The presence of OAISO has not been emphasized previously and still remains controversial. We felt that an extremely tight superior oblique might cause an OAISO. We therefore statistically compared its presence to the presence of a downshoot. The presence of an OAISO to abnormal head tilt, abnormal chin position, amblyopia, and abnormal stereo was also compared statistically. Finally, we emphasize a technique of forced ductions that differentiates Brown's syndrome from an inferior oblique palsy, but which also alerts the examiner to the presence of an inferior rectus restriction or other posteriorly located restrictions.

Congenital glaucoma associated with cutis marmorata telangiectatica congenita: two case reports.

Two cases of cutis marmorata telangiectatica congenita are described in association with nevus flammeus and congenital glaucoma. Approximately 65 cases have been reported and the association with nevus flammeus and congenital glaucoma has only been reported in one of those cases. Unlike the glaucoma associated with nevus flammeus of Sturge-Weber, this type of congenital glaucoma appears to be associated with an abnormal filtration angle rather than an increased episcleral venous pressure.

Cystoid macular edema in pediatric aphakia.

The presence of cystoid macular edema (CME) after cataract extraction in the pediatric age group could adversely affect rapid visual rehabilitation of the eye by contributing to irreversible amblyopia. Several previous studies, including one by our group, have addressed this problem. Hoyt's observations of CME in ten of 27 eyes undergoing lensectomy-vitrectomy procedures have stirred renewed interest in this topic. The current study includes 12 eyes undergoing lensectomy-vitrectomy procedures, five eyes undergoing manual extracapsular procedures (ECCE) with discission of the posterior capsule, three eyes undergoing ECCE without discission of the posterior capsule, and three eyes undergoing secondary discissions. No CME was found angiographically on postoperative evaluation.
