Abstract

To determine if resuturing of the scleral flap to increase IOP in the post-trabeculectomy eye is an effective treatment of hypotony maculopathy. The medical records of nine consecutive patients who developed visual acuity loss after trabeculectomy related to hypotony maculopathy were reviewed to determine factors that contribute to successful restoration of visual acuity. The average age of the patients was 50 years and average refractive error was -4.25 diopters (D). Mean Snellen visual acuity dropped from 20/25 to 20/200 after the onset of hypotony. Six of nine eyes recovered visual acuity to within one line of initial level after treatment of the hypotony. Four of these six eyes underwent resuturing of the scleral flap to reverse the excess filtration within 6 months of the onset of hypotony maculopathy. Five of these six patients had final vision of 20/30 or better. The mean phakic preoperative refractive error in these six eyes was -2.25 D, compared with a mean refractive error of -8.50 D in the three eyes with persistent visual loss (P = 0.002). After reversal of the hypotony, the average peak intraocular pressure in the six eyes with visual recovery was 33 mm Hg, compared with an average peak IOP of 7 mm Hg in the three ...Continue Reading

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.
