BackgroundWe evaluated the surgical outcomes of vitrectomy with non-fovea-sparing internal limiting membrane (ILM) peeling for myopic foveoschisis with a follow-up of at least 3 years.MethodsIn this retrospective study, 32 consecutive eyes with high myopia with or without foveal detachment underwent vitrectomy and centripetal, non-fovea-sparing ILM peeling with gas tamponade for myopic foveoschisis. Outcome measures were visual acuity (VA) and optical coherence tomography findings.ResultsMean axial length was 29.39±1.92 mm; mean follow-up was 42.66 (±8.29) months. Foveoschisis and foveal detachment completely resolved in all eyes postoperatively. Mean central foveal thickness (CFT) improved significantly from 631.88±191.72 to 232.65±69.67 µm, and mean best-corrected visual acuity improved significantly from 0.90 (Snellen equivalent (SE), 20/160)±0.43 logarithm of minimum angle of resolution (logMAR) to 0.43 (SE, 20/54)±0.29 logMAR (both p<0.001; two-tailed, paired t-test). Eyes with foveal detachment (n=10) at baseline had thicker preoperative CFT (737.8±239.83 vs 583.73±147.78 µm; p=0.033) but thinner postoperative CFT (188.20±31.52 vs 252.86±73.29 µm; p=0.012). Eyes without foveal detachment at baseline had significantly better postoperative VA (0.33 (SE, 20/43)±0.18 vs 0.65 (SE, 20/86)±0.37 logMAR; p=0.002). No macular hole or other complications occurred during follow-up.ConclusionCentripetal, non-fovea-sparing ILM peeling with gas tamponade may achieve myopic foveoschisis resolution and vision improvement without macular hole formation during at least 3-year follow-up.
Background: Posterior segment metallic intraocular foreign bodies (IOFBs) are a leading cause of visual morbidity and blindness, especially among young and middle-aged working populations. Here, we aimed to evaluate the surgical outcomes of the removal of such IOFBs that result from injuries. Methods: In this retrospective study, 39 patients injured by metallic posterior segment IOFBs and who underwent primary repair procedures, vitrectomies, and IOFBs removal with or without procedures for traumatic cataract removal, scleral buckling and intraoperative tamponade application from January, 2008 to January, 2019. We analyzed the preoperative, intraoperative and postoperative related factors that affect the final visual outcomes. Results: The mean age of the 39 patients was 40.51 ± 12.48 years with the male being predominent (100%).The mean preoperative vision measured 1.50 [Snellen Equivalent (SE), 20/645] ± 1.12 logMAR with the mean final vision measuring 0.93 (SE, 20/172) ± 1.09 logMAR. The related factors that were determined to affect the final visual outcomes included preoperative vision (P = 0.025), IOFB-related macula injuries (P = 0.001) and the development of postoperative complications (P = 0.005) especially retinal detachment (P = 0.002) with the mean final vision measuring 2.12 (SE, counting finger to hand motion) ±1.23 logMAR. Concerning the preoperative signs, the patients with preoperative endophthalmitis also obtained poor mean final vision measuring 1.30 (SE,20/400) ± 1.40 logMAR. Conclusion: IOFB-related macula injuries and postoperative retinal detachment were important related factors of poor final visual prognoses in cases involving posterior segment metallic IOFBs. Removing IOFB as early as possible may prevent preoperative endophthalmitis which could lead poor final visions even without significance.
BackgroundLaser in situ keratomileusis (LASIK) is the most common and popular procedure performed for the correction of refractive errors in the last two decades. We report a case of traumatic flap displacement with flap folding which occurred 3 years after LASIK was performed. Previous literature suggests that vision prognosis would be closely related to proper and prompt management of traumatic flap displacement with flap folding 3 years after LASIK.Case presentationA 23-year-old female presented to our hospital who had undergone uneventful LASIK in both eyes 3 years prior. Unfortunately, she had suffered a blunt trauma in her right eye in a car accident. A late onset of corneal flap displacement was found with upper and lower portion of the flap being folded inside the corneal bed. Surgical intervention for debridement with subsequent reposition of corneal flap was performed as soon as possible in the operating room. A bandage contact lens was placed, and topical antibiotic and corticosteroids were given postoperatively. Two days after the operation, the displaced corneal flap was found to be well attached smoothly on the corneal bed without folds. The best-corrected visual acuity was 6/6 with refraction of −0.75 D to 1.0 D ×175° in her right eye 1 month later.Literature reviewWe reviewed a total of 19 published cases of late-onset traumatic flap dislocations or displacements after LASIK with complete data from 2000 to 2014.ConclusionTraumatic displacement of corneal flaps after LASIK may occur after blunt injury with specific direction of force to the flap margin, especially tangential one. According to the previous literature, late-onset traumatic flap displacement may happen at any time after LASIK and be caused by various types of injuries. Fortunately, good visual function could mostly be restored with immediate and proper management.
We reported a rare case of sudden onset of severe but reversible suprachoroidal air that occurred at the moment of air–fluid exchange in 23-gauge vitrectomy. A 31-year-old male patient presented with a large break at 10–11 o’clock and high bullous, nearly total retinal detachment. He underwent first surgery with silicon oil injection at the end of the surgery. He was arranged to have a second surgery for silicon oil removal through pars plana vitrectomy which was performed smoothly at first. While switching to another mode of air–fluid exchange to clean the residual emulsified oil droplets, surgical view disappeared completely and was suddenly replaced with severe and total suprachoroidal air, which fortunately resolved within 3 days without any other severe complications.
BackgroundEndogenous endophthalmitis, extra-hepatic metastasis from liver abscess with diabetes mellitus, could lead to a devastating outcome without a prompt and appropriate management. We report a case of metastatic endophthalmitis combined with subretinal abscess with successful visual outcome after treatment.Case presentationA 56-year-old male patient with diabetes mellitus under poor control presented to our emergency room with fever, sore throat, cough and poor appetite for 2 weeks. Abdominal computed tomography showed a 2.2 × 2.0 cm liver abscess. During hospitalization, sudden onset of blurred vision with floaters in his left eye was noted.Meanwhile, Brain computed tomography demonstrated subdural abscess in right parietal area. With obvious vitritis, a localized subretinal abscess was also found over temporal arcade with size about four disc areas under indirect ophthalmoscopy. A pars plana vitrectomy with intravitreal injection of ceftazidime (2 mg/0.1 ml) and amikacin (0.4 mg/0.1 ml) was performed without retinectomy. The margin of the subretinal abscess became firm and the central area resolved after the operation. Finally, his vision improved to 6/6 after cataract surgery.ConclusionsSubretinal abscess is an extremely rare presentation of metastatic endophthalmitis. It is difficult to develop appropriate treatment guidelines of endophthalmitis complicated with subretinal abscess. Our experience in this case demonstrated if the size of the subretinal abscess is smaller than four disc areas, pars plana vitrectomy with intravitreal injection of antibiotics without retinectomy could be considered to avoid further retinal detachment.
