Vitreoretinal surgery performed through a 60-diopter lens.

For vitreoretinal surgery, we recommend using a 60-diopter lens for indirect ophthalmoscopy through the operating microscope without internal illumination. This device has undergone extensive clinical testing since 1986 with excellent results.

Retinal break type and proliferative vitreoretinopathy in nontraumatic retinal detachment.

In a retrospective study of 1180 consecutive eyes operated for retinal detachment, vitreous traction on the rent was the determining factor for the development of proliferative vitreoretinopathy (PVR). Round, multiple, small holes in equatorial degeneration (retinogenic) and macular holes in which no vitreous traction on the rent was found did not complicate with PVR. Retinal detachment caused by horseshoe or crescent-shaped tears with evidence of vitreous traction (vitreogenic) developed PVR to a variable degree: in 171 (25.8%) senile myopic, 19 (44.2%) senile-myopic aphakic, 23 (20.2%) typical aphakic, and 32 (78.1%) patients with giant tears. We also found that retinogenic retinal detachments affected younger age groups more than did vitreogenic retinal detachments.

Myopic and nonmyopic aphakic retinal detachment: time interval and location of breaks.

Of 471 retinal detachments occurring in aphakic patients after undergoing intracapsular cataract extraction, we reviewed 318 eyes with uncomplicated aphakia (no vitreous loss). Myopic eyes had equatorial breaks 38% of the time versus 19% for nonmyopic eyes. The time interval between aphakia and detachment was shorter for myopic than for nonmyopic eyes. Our results showed a significant incidence of: (1) equatorial breaks in myopic eyes versus nonmyopic eyes (P less than 0.005), and (2) earlier detachments for myopic eyes versus nonmyopic eyes (P less than 0.005). The presence of equatorial breaks seemed to be associated with earlier retinal detachments.

Lens guide suture for transport and fixation in secondary IOL implantation after intracapsular extraction.

The authors, after analyzing the different clinical situations where a secondary IOL implantation is indicated, describe 3 surgical techniques based on a common premise relying on the use of lens guide sutures for transportation or transportation and permanent fixation of the IOL's loops. The transportation sutures makes secondary implantation easier in anterior chamber lenses in technique I. The double purpose of transportation and permanent fixation at the angle permits a safe procedure with anterior chamber lenses in cases with no iris support in technique II and the possibility of sulcus or ciliary body fixation of a J type posterior chamber lens after ICCE in technique III.

Punctiform and polychromatic pre-Descemet's dominant corneal dystrophy.

A new type of pre-Descemet's corneal dystrophy is described. The opacities are punctiform, polychromatic, of uniform size, and evenly distributed over the whole cornea. The diagnosis is made only by slit lamp because there is no visual impairment. The disease is hereditary and follows the autosomal mode of inheritance with a high percentage of penetrance, expressivity, and specificity in 4 successive generations, in which 8 affected members were observed among a total of 46.

The influence of new surgical procedures on retinal pathology in aphakia after congenital cataract surgery.

After reviewing the incidence of aphakic retinal detachment more specifically on eyes that have been submitted to surgery for congenital cataracts, the authors make some remarks and discuss the value, the advantages, and the yet unknown risks that the new methods of lens removal may have as regards retinal pathology. Special consideration is given to the balance of the advantages: more complete elimination of the opacities, lower incidence of immediate morbidity, better visual results and postoperative possibilities of retinal examinations; against the, as yet unknown, late retinal complications with new procedures such as ultrasonics, phacoemulsification, pars plana approach for lens removal, etc. Moreover, bearing in mind the typical late onset of retinal detachment in aphakic eyes after congenital cataract surgery with the older methods, such as linear extraction and multiple discussions, special attention is given to this feature as a comparative landmark for a prospective evaluation of recent methods of extracapsular lens surgery.
