Cataract surgery with intraocular lens implantation by ophthalmology resident surgeons.

Cataract surgery with intraocular lens implantation (cataract-IOL surgery) performed by ophthalmology residents under supervision of experienced surgeons in 1974-1978 was analyzed. Retrospective evaluation of 32 cases noted patient age and sex distribution, preoperative ophthalmic examination findings, technique for cataract surgery with implantation of iris support intraocular lenses, postoperative complications, and visual acuity with best correction 30 months after surgery as well as on the last examination. Postoperative follow-up, ranging from one to 84 months, recorded a visual acuity with best correction of 20/40 or better in 87.5% of cases. Excluding two cases in which decreased visual acuity resulted from macular degeneration, visual acuity with best correction was 20/40 or better in 94% of cases.

Obtaining auricular cartilage for reconstructive surgery.

The cartilage in the scaphoid fossa between the helix laterally and the antihelix medially provides excellent underlying support for soft-tissue eyelid and nasal reconstruction. After subcutaneous infiltration anesthesia is administered through both the anterior and posterior auricular skin, an incision is made along the posterior rim of the helix. A dissection plane between the perichondrium and skin exposes the cartilage. The cartilage is removed without incising the anterior skin surface. This technique is particularly useful in cicatricial entropion, upper or lower eyelid retraction, eyelid reconstruction, and socket reconstruction.

Parotid duct injury as a complication of differential seventh nerve ablation.

A 68-year-old man with intermittent blepharospasm complained of pain and induration after undergoing differential ablation of the seventh nerve. Because radiation therapy was ineffective, we inserted a 5-mm silicone tube into a serous cyst in the parotid gland. The induration subsided and the patient's recovery was uneventful.

Complications at mucous membrane donor sites.

Full-thickness mucous membrane is an acceptable autogenous graft to replace the deficient conjunctiva resulting from intrinsic disease, surgical resection for carcinoma, or reconstruction of contracted sockets. The mouth provides an excellent source of mucous membrane graft material with few donor site complications. However, we encountered four cases of donor site complications after full-thickness mucous membrane grafting. All cases involved submucosal scarring with contracture. Because the inner aspect of the mouth is a multicontoured surface, the submucosal scarring resulted in web formation and limitation of movement of the mandible or lip. In two cases, we resected submucosal fibrotic scar tissue and designed a standard or multiple Z-plasty to release mucosal tension. This allowed a return to normal oral function.

Ocular motility problems after orbital decompression for dysthyroid ophthalmopathy.

Ocular motility problems of 50 consecutive patients following orbital decompression for dysthyroid (Graves') ophthalmopathy were analyzed retrospectively. No significant relationship to the development of postoperative diplopia was seen in the amount of retrodisplacement of the globe, the anatomical approach for orbital decompression, or the indication for decompression. Several clinical observations were made. Patients whose indication for orbital decompression was a vision-threatening ophthalmopathy were more likely (although not statistically significantly) to develop postoperative strabismus. Patients who developed changes in preoperative strabismus were more likely to develop increased esotropia and/or restrictive hypertropia. Of 32 patients who were orthotropic in the primary position before operation, 11 developed postoperative strabismus in the primary position. Only five patients had normal versions and ductions before operation. All five of these patients had normal versions and ductions after operation.

Chest pain in the postoperative ophthalmic patient.

A retrospective analysis of the postoperative ophthalmic surgical mortality during the 20-year period ending in 1974 at the Jules Stein Eye Institute was performed. Eleven of 17,632 patients died following ophthalmic surgery (0.062%). Frequently, the cause of death was related to pulmonary embolism, myocardial infarction, congestive heart failure, or pneumonia. The postoperative complications were often heralded by complaints referable to the chest, and misdiagnosis was common. A simplified approach to postoperative chest pain based on location is presented.

Mydriatic effect of phenylephrine 10% (aq) vs phenylephrine 2.5% (aq).

Pupil dilation from commercially available phenylephrine compounds was studied in a group of 11 subjects. Phenylephrine 10% (aq) did not produce significantly more mydriasis than phenylephrine 2.5% (aq) in the general population (P less than 0.05). This suggests that phenylephrine 2.5% can be used instead of phenylephrine 10% for diagnostic dilation.
