Ultrasound in early thyroid orbitopathy.

Fourteen patients with unilateral exophthalmos were found on A-scan ultrasound examination to have enlarged extraocular muscles. Thyroid dysfunction later was documented in 12 patients (86%) by laboratory tests and subsequent clinical examination. The suspicion of endocrine orbitopathy was based on the presence of enlarged extraocular muscles in both orbits and on the difference in thickness between corresponding muscles. A-scan orbital examination including specific muscle measurements is a simple and apparently reliable method of diagnosing early thyroid orbitopathy.

Constant mild compression of the eye as an alternative to ocular massage.

Constant mild compression of the eye with a rubber ball for 30 minutes prior to cataract extraction seems to be an efficient alternative to preoperative ocular massage. The average preoperative intraocular pressure was 4.34 mm Hg compared to 8.36 with digital massage and 6.31 with digital massage and I.V. Mannitol. The incidence of vitreous loss was 0.88% compared to 5% with digital massage.

Primary vs. secondary insertion of anterior chamber lenses.

In this prospective study, patients with cataracts were divided into two groups. In Group I, intracapsular cataract extraction with anterior chamber lens insertion was performed as a one-step procedure. Patients in Group II underwent intracapsular cataract extraction followed by secondary insertion of an anterior chamber lens two to three months later. The higher incidence of CME seen with the secondary procedure seems to indicate that primary rather than secondary insertion of anterior chamber lenses is advisable.

Secondary lens implantation in aphakia: visual results and complications.

We reviewed 70 cases that had undergone secondary lens implantation. The lenses used included 34 Medallion and 36 Choyce Mark VIII lenses. A 20/40 or better vision was present in 74.3% of the cases before implantation, and could be achieved postoperatively in 95.7% of the cases. Corneal changes, i.e. endothelial corneal dystrophy and induced astigmatism, were not noted in cases where Choyce Mark VIII lenses were used. Cystoid macular edema occurred in three cases where surgery followed an intracapsular cataract extraction (5.3%).

Distichiasis of the lids and lymphedema of the lower extremities: a report of ten cases.

Ten members belonging to two different families were affected by distichiasis of the lids (double row of eyelashes) and lymphedema of the lower extremities. Other less frequent congenital anomalies, such as pterygium colli and ptosis were found in some affected members. The previously reported cases were reviewed. A single pleiotropic gene with a high penetrance and a variable expressivity is responsbile for the different anomalies of this dominantly inherited syndrome.

Retinal disinsertion syndrome: report of a case.

A case of retinal disinsertion syndrome in a 31-year-old mentally retarded patient was reported. Associated anomalies included subluxation of the lens, microphthalmos and bilateral keratoconus. Total retinal detachment and subluxation of the lens in a blind microphthalmic eye of a young infant should raise the possibility of retinal disinsertion syndrome.
