Abstract

Choroidal neovascularisation (CNV) occurs rarely following laser photocoagulation for macular oedema in diabetic retinopathy, and its management is not well established. We report the clinical course and visual outcomes in a series of patients who underwent surgical extraction of the CNV membrane. A retrospective review of 4 cases was carried out. Two women and 2 men, mean age 59.5 (range 58-62) years, were reviewed. The CNV developed 2-24 (mean 11) months after laser coagulation and resulted in decreased visual acuity to between 6/60 and HM. All underwent pars plana vitrectomy, extraction of the CNV membrane and fluid-air exchange. Follow-up ranged between 9 and 48 months. In 2 patients, the vision improved by 4 and 1 Snellen lines respectively and remained stable, in 1 patient it improved by 1 line initially but then regressed to CF, and in 1 patient it remained unchanged. Recurrence of CNV occurred in only 1 patient. Histological characteristics were those of CNV without evidence of photoreceptors. This study shows that surgical removal of post-laser CNV is technically feasible despite the previous laser scars and may have beneficial outcome. This surgical approach may provide a therapeutic option in such patients.

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
