Proximity-sensor dimmer device as an aid in the reduction of operating microscope-induced retinal phototoxicity.

The length of exposure to the light source of the operating microscope is a major factor determining retinal phototoxicity. In our experience, for about 20% of the time during cataract surgery, the surgeon is not looking through the oculars. To take advantage of these times, we designed a device, a proximity switch consisting of an infrared sensor mounted between the oculars in the operating microscope. When the surgeon's forehead approaches the microscope to look through the oculars, the sensor increases the illumination; when the surgeon moves away, it is automatically reduced. The resulting decreased overall exposure to light may reduce retinal phototoxicity.

[Acanthamoebic keratitis].

Acanthamoebic keratitis is still a rare infection. It occurs in contact lens-wearers, especially when saline is prepared at home from contaminated tap water. There are periods of remission, and occasionally misleading findings resembling those of herpetic keratitis, which make the diagnosis difficult. The isolation of the acanthamoeba is not easy and special culture media are required. Early recognition and aggressive therapy with antiamebic medication and epithelial debridement, often in conjunction with penetrating keratoplasty, are needed. We describe the clinical course, laboratory diagnosis and treatment of 3 patients with acanthamoebic keratitis, 2 men aged 20 and 25, respectively and a women aged 42.

Corneal graft rejection after neodymium-yttrium-aluminum-garnet laser posterior capsulotomy.

Neodymium-yttrium-aluminum-garnet (Nd-YAG) laser capsulotomy was performed in three patients with corneal graft. Acute corneal graft rejection was noted in these patients 4 weeks to 4 months after posterior capsulotomy. In one patient, enlargement of the capsulotomy opening was followed by a second episode of corneal graft rejection. We discuss the complications of Nd-YAG laser capsulotomy, and its possible role as a cause for corneal graft rejection.

Silicone oil-induced corneal hydrops?

A 27-year-old man with a personality disorder, who did not have keratoconus previously, recently presented with a clinical picture resembling acute corneal hydrops OS three years after silicone oil injection for a complicated retinal detachment. Although self-induced trauma could not be excluded completely, this case might represent a newly described late corneal complication of intracameral silicone oil.
