Angiographic Cystoid Macular Edema After Posterior Chamber Lens Implantation

Early Post-Operative Complications in Cataract Surgery

“…Iris prolapse is extremely rare following small incision surgery but may occur after extracapsular cataract extraction (Figure 2) (Reddy, 1995). Complications include defective wound healing, chronic anterior uveitis, excessive astigmatism, endophthalmitis, cystoid macular oedema and epithelial ingrowth (Wright et al, 1988). Peribulbar or retrobulbar anaesthesia is necessary for iris manipulation.…”

“…Postoperative corneal stromal oedema could also indicate pre-existing endothelial pathology as in Fuchs' endothelial dystrophy. Pre-operatively patients should be carefully examined for evidence of Fuchs' dystrophy or other conditions that produce a low endothelial cell count (Reddy, 1995;Wright et al, 1988;Yanoff & Duker, 2004). Previous studies have found that at birth the corneal endothelial cell density is approximately 5,000 cells/mm 2 and until the age of 20 years there is a significant decline in this number.…”

Retinal thickness assessed by optical coherence tomography (OCT) in pseudophakic macular edema

“…The angiographic macular edema (ACME), detected by the fifth post-operative week is reported in 24% (4) of eyes with posterior chamber lens implants and, as many as 50% using several cataract extraction techniques (5) . Routinely, macular edema has been diagnosed by slit lamp biomicroscopy and fluorescein angiography (4)(5)(6) .…”

“…Although only a small percentage of eyes were reported to show a substantial reduction of visual acuity due to pseudo- (4,6,16) , this entity still continues to be troublesome for doctors and their patients after uneventful cataract extraction. This study was conducted to evaluate the usefulness of the OCT retinal map in ACME diagnosis.…”

“…Routinely, macular edema has been diagnosed by slit lamp biomicroscopy and fluorescein angiography (4)(5)(6) . Biomicroscopy of the macula is a difficult, subjective and often an inconclusive examination of recently operated eyes due to photophobia and light diffraction in the eye or in the intraocular lens.…”
