[IOL and aniseikonia calculation combined with documentation of surgical data and IOL inventory].

The exact recording of operation data is a precondition for keeping the standards high in cataract surgery, but surgeons are reluctant to answer a questionnaire after a strenuous operation. We have designed a program easy to use in the Macintosh Hypercard System that covers all aspects of cataract surgery such as: (1) the operating record; (2) a data sheet for recording the various details of the operation; (3) recording of the data on hard disc; (4) managing the IOL stock list; (5) proposal of IOL models that are in stock with regard to IOL power (SRK2) and aniseiconia. This program enables the surgeon to record the operation data with effortless ease and it is well accepted.

[Changes in the pattern electroretinogram in glaucoma and ocular hypertension are dependent on stimulus frequency].

A pattern electroretinogram (PERG) was recorded in patients in the initial stages of visual field defects resulting from open-angle glaucoma, in patients with ocular hypertension (OHT) and in age-matched controls. In both groups the visual acuity was above 0.8.

Check-size specific changes of pattern electroretinogram in patients with early open-angle glaucoma.

The pattern electroretinogram was recorded in patients with initial stages of visual field defects due to open-angle glaucoma and in age-matched normal subjects. Both normal subjects and glaucoma patients had a visual acuity above 0.8.

Solitary retinovitreal abscess as the initial manifestation of cryptococcosis.

In a 63-year-old white man with a history of long-term use of systemic corticosteroids for polyarteritis nodosa, progressive clouding of vision in the right eye developed over a 2-month period. Cytologic analysis of a fine-needle aspiration biopsy of a solitary fluffy retinovitreal mass demonstrated Cryptococcus neoformans. Subsequent cerebrospinal fluid cultures were also positive for C.
