RESUMEN
Purpose@#To evaluate the clinical outcomes of nanothin Descemet stripping automated endothelial keratoplasty (DSAEK) in Korean patients with corneal endothelial dysfunction. @*Methods@#We retrospectively reviewed medical records of the patients who underwent nanothin DSAEK (graft thickness ≤50 μm) due to corneal endothelial dysfunction and followed up more than 1 year. We evaluated best-corrected visual acuity (BCVA), central corneal thickness, and corneal endothelial cell density at preoperative and 1, 3, 6, and 12 months postoperatively. @*Results@#Sixteen eyes of 16 patients with the mean follow-up period of 13.00 ± 0.96 months were included. The mean graft thickness after deswelling was 45.25 ± 4.59 µm (range, 38.0–50.0 µm). The mean logarithm of the minimum angle of resolution BCVA improved from 1.37 ± 0.53 preoperatively to 0.68 ± 0.46, 0.55 ± 0.35, 0.40 ± 0.25, and 0.39 ± 0.25 at 1, 3, 6, and 12 months postoperatively (p = 0.005, p < 0.001, p < 0.001, and p < 0.001), respectively. The mean central corneal thickness improved from 752.00 ± 129.11 to 555.75 ± 54.66 µm at 12 months postoperatively (p = 0.006). The mean graft endothelial cell density decreased from 2,859.62 ± 228.34 to 1,542.25 ± 627.34 cells/mm2 at 12 months postoperatively (p = 0.012). The postoperative complications included increased intraocular pressure (n = 3, 18.75%) and graft dislocation (n = 1, 6.25%), all of which were successfully managed by anterior chamber paracentesis or rebubbling. No other serious complications were encountered. @*Conclusions@#Nanothin DSAEK produced significant and stable visual improvements without severe postoperative complications in Korean patients with corneal endothelial dysfunction.
RESUMEN
Purpose@#To report a satisfactory clinical outcome of hemorrhagic retinal macrocyst with retinal detachment after pars plana vitrectomy and silicone oil injection. Case summary: A 33-year-old man visited our clinic with a 1-week history of visual disturbance in his left eye. His ocular and medical history were unremarkable, and best-corrected visual acuity (BCVA) in the left eye was 20/40. Fundoscopic examination of the left eye showed a hemorrhagic retinal macrocyst that was well-demarcated, semi-transparent, dome-shaped, and larger than 8 disc diameters at the superonasal location, with macular-off retinal detachment. B-scan ultrasonography also confirmed the presence of an intra-retinal cystic lesion with internal mobile echogenic signals representing blood. The patient underwent 23-gauge pars plana vitrectomy, barrier laser photocoagulation around the retinal tear and boundary of the cyst, and silicone oil injection, without any other additional procedures for the hemorrhagic retinal macrocyst. After the surgery, the patient stayed in the face down position for two weeks. Three months postoperatively, a completely collapsed hemorrhagic retinal macrocyst with successful retinal reattachment was observed. Six months later, the BCVA in the left eye had improved to 20/30. One year later, even after silicon oil removal, the collapsed hemorrhagic retinal macrocyst and reattached retina remained stable. @*Conclusions@#A hemorrhagic retinal macrocyst with retinal detachment was successfully treated with pars plana vitrectomy and silicone oil tamponade.
