The Swedish national survey of surgical excision for submacular choroidal neovascularization (CNV).

Purpose: To compare the visual outcome after surgical removal of subfoveal choroidal neovascularization (CNV) in patients younger and older than 50 years of age.

Methods: Patient records from all Swedish centers performing submacular CNV surgery were reviewed and 90 patients treated between 1992-1999 with a follow-up of 6 months or more were included. The results obtained in 49 patients aged 51-89 years (median=72 years) with neovascular disease caused by age-related macular degeneration (AMD) were compared with the outcome of 41 patients aged 6-49 years (median=36 years) with CNV secondary to non-AMD causes.

Tackling the "dropped nucleus".

Purpose: To summarize and analyse the results of our experience in treating patients with a "dropped nucleus".

Methods: The case records of nineteen patients who underwent surgery for a "dropped nucleus" at the Ophthalmology Departments of Sahlgren's University Hospital, Gothenburg, and Orebro Medical Centre, Orebro, Sweden during 1994 were retrospectively reviewed to determine the mode of treatment used and the results of surgery. The frequency of this complication was also calculated for Sweden as a whole with the help of the National Cataract Register.

Long-term results of macular pucker surgery.

Purpose: Macular pucker patients were re-examined 16-90 months after surgery (mean 72 months) to evaluate visual acuity, metamorphopsia, and complications, with particular reference to cataract development. Surgery had been performed on 48 eyes in 46 patients, 31 eyes having a primary, and 17 eyes a secondary macular pucker.

Results: At the 6-month control 65% of the eyes with a primary macular pucker and 35% of the eyes with a secondary macular pucker exhibited an improved visual acuity defined as doubling or more of the visual angle.
