Decompression retinopathy following nonpenetrating deep sclerectomy for primary congenital glaucoma.

BACKGROUND: To describe a unique case of decompression retinopathy manifesting as pre-macular subhyaloid hemorrhage that occurs in a nine-day old child after undergoing a non-penetrating deep sclerectomy for primary congenital glaucoma. CASE PRESENTATION: We report a single case of a 9-day-old boy who was referred to our department of ophthalmology for bilateral buphtalmia and corneal edema. He presented marked elevation of the intraocular pressure in both eyes (22 mmHg and 26 mmHg, in the right eye and left eye respectively) associated with significant optic nerve cupping. Non-penetrating deep sclerectomy was performed for each eye, with effective reduction of the intraocular pressure during the first week postoperatively (11 mmHg and 7 mmHg in the right eye and left eye respectively). The right eye presented an isolated subhyaloid hemorrhage located in the pre-macular area, persisting 3 weeks after the initial surgery and requiring pars-plana vitrectomy to clear the visual axis. This uncommon complication was identified as decompression retinopathy. The intraocular pressure remained controlled in the normal range three years after initial surgery in both eyes, with reversal of optic disc cupping. CONCLUSIONS: Decompression retinopathy is a potential complication after non-penetrating deep sclerectomy in primary congenital glaucoma, requiring prompt treatment strategy to prevent potential organic amblyopia.

The discovery of the disease called glaucoma dates back to the 17th century. Its important role as a cause of blindness has been known since the 19th century. Initial comprehension of this pathogenesis and treatment belong to the 20th century. Its prevention will hopefully be the work of the 21st century.

Cataract surgery and transpupillary silicone oil removal through a single scleral tunnel incision under topical anesthesia; sutureless surgery.

The author evaluated the results of combined cataract extraction and transpupillary silicone oil removal through a single scleral tunnel incision, in eyes that had undergone pars plana vitrectomy with silicone oil tamponade. Twenty-four of the 46 eyes were operated on under topical anesthesia with Blumenthal mode mini-nucleus manual extracapsular cataract extraction technique (mini-nuc ECCE), and silicone oil was removed passively through planned posterior capsulorhexis via the scleral tunnel, followed by endocapsular intraocular lens (IOL) implantation. The operation was completed without any suturing. The remaining 22 eyes were similarly operated on with the same cataract extraction technique, but in these cases silicone oil was classically aspirated actively through pars plana sclerotomies. Results were evaluated by visual acuity measurement, duration of operation, and complications. The transpupillary silicone oil removal group had significantly less vitreous hemorrhage (0- 31.8%) and posterior capsule opacification (0-36.4%). Also, the mean duration of the operation was significantly shorter in this group. There was no significant difference between the two groups with regard to postoperative recurrence of retinal detachment (12.5-18.1%) and visual acuity outcome. The combination of mini-nuc ECCE with transpupillary silicone oil removal compares favorably with the combination of silicone oil aspiration through pars plana sclerotomies. This combined technique allows the surgeon to perform the operation under topical anesthesia and no sutures are required. The intervention period is shorter and no posterior capsule opacification or vitreous hemorrhage develops.
