A cross-sectional study of macular displacement after macular hole surgery with ILM peeling in patients with idiopathic macular hole.

PURPOSE: To examine the retinal displacement and change in mean superficial foveal avascular zone (FAZ) after successful closure of macular hole (MH) with vitrectomy with internal limiting membrane peeling (ILM) and gas tamponade. METHODS: A total of 45 patients with idiopathic MH who underwent 23G pars plana vitrectomy with ILM peeling and tamponade with 20% SF6/14% C3F8 were included. Follow-up visits were performed at 2, 4, and 8 weeks. OCT and OCT-A scans were performed along with detailed ocular examination. Distance between optic disc and an easily identifiable vascular bifurcation nasal and temporal to fovea, FAZ, was noted. Chi-square test (categorical data) and Mann-Whitney U test and t tests for other parameters were performed for statistical analysis. RESULTS: The mean displacement (µm) of an easily identifiable vascular bifurcation in the nasal quadrant was 96.58 ± 36.55 at 8 weeks and in the temporal quadrant was 273.07 ± 85.51 at 8 weeks. The change was statistically significant in the temporal quadrant (P = <0.001). The mean BCVA changed from a minimum of 0.08 at the preoperative timepoint to a maximum of 0.23 at 8 weeks (P = <0.001). The mean FAZ area (mm²) decreased from a maximum of 0.37 at the preoperative timepoint to a minimum of 0.19 at 8 weeks (p = <0.001). CONCLUSION: The retina in the temporal quadrant is displaced significantly more than nasal quadrant after successful closure of macular hole. The mean superficial FAZ also decreases suggesting a centripetal movement of the foveal tissue postoperatively.

Button-Hole Disco-Osteotomy Drainage-A Novel Approach for High-Risk Patients with Cervical Abscess.

Spinal epidural abscess (SEA) is a very serious infection of the central nervous system (CNS). It is of very low incidence with a peak age in the geriatric age group. Immunocompromised patients are more susceptible to SEA. It can present with significant neurological deficits, which can be permanent if not identified and treated promptly. In this case report, a 75-year-old immunocompromised patient presented with progressive spastic quadriparesis and septicemia. He was diagnosed with a case of cervical spinal epidural abscess with underlying cord compression. Anterior retropharyngeal approach and button-hole disco-osteotomy of C5-C6 was performed and the cervical SEA was drained, followed by antibiotic saline irrigation (cranially and caudally) was done, total duration of surgery was 70 min. At the time of discharge (7th postoperative day), the patient improved neurologically and sepsis had resolved.

Management of traumatic dislocation of crystalline lens: Retropupillary iris-claw versus sutureless intrascleral-fixated intraocular lens.

PURPOSE: The purpose of this study was to compare the long-term efficacy and safety of posterior iris-claw lens and scleral-fixated posterior chamber lens for aphakia after traumatic posterior dislocation of the crystalline lens. MATERIAL AND METHODS: Out of 120 evaluated cases, 60 were randomly assigned in each group. A 23G vitrectomy was done and intraocular lens was implanted by two different techniques. Extensive preoperative and postoperative evaluation was performed including optical coherence tomography and Scheimpflug imaging. Follow-up was done on days 1, 7, and 28 at 3 months, 6 months, and 12 months. RESULTS: A significant improvement was found in uncorrected visual acuity in both the groups. Surgical time in iris fixation was significantly less (P < 0.001), whereas pupil peaking and pigment release were more. Difference in mean intraocular pressure and change in astigmatism in both the groups were insignificant. CONCLUSION: Both the techniques had similar good visual results. Although operating time was shorter for iris fixation, it had several disadvantages, including immediate postoperative inflammation and ovalling of the pupil. However, scleral fixation had a better outcome in terms of postoperative complications.

A rare case of orbital lymphangioma with persistent fetal vasculature and extraorbital vascular malformations treated with intralesional bleomycin.

Orbital lymphangiomas are isolated, benign vascular malformations of childhood. We report a case of orbital lymphangioma with acute intralesional hemorrhage in a 4-year-old boy that was associated with ipsilateral persistent fetal vasculature and extraorbital vascular malformations. Complete resolution of orbital lesion was achieved with chocolate cyst aspiration and intralesional injection of bleomycin.

Sutureless glueless intrascleral fixation of posterior chamber intraocular lens: Boon for aphakic.

PURPOSE: To report results of intrascleral fixation of 3-piece IOL without the help of suture and glue. METHODS: Study included intrascleral fixation of haptic in 50 eyes by T-fixation technique. Preoperative and postoperative visual acuity, slit lamp and fundus examination, applanation tonometry, keratometry, biometry, optical coherence tomography, Scheimpflug imaging were done for extensive evaluation. Qualitative and quantitative data were summarized in the form of proportion and mean and standard deviation, respectively. The significance of difference was measured by Chi-square test or unpaired t-test or ANOVA whichever is appropriate. P < 0.05 was considered as statistically significant. RESULTS: There was one case in which haptic broke during handshake maneuver and another IOL was required. Postoperative complications included corneal edema (4%), increased intraocular pressure (6%), cystoid macular edema (2%), decentration (4%), and dislocation (2%), which were all managed to the level of good visual recovery. There was no significant change in corneal astigmatism. There was significant change found in best-corrected visual acuity and uncorrected visual acuity after surgery. CONCLUSION: This modified technique seems to be a good alternative in IOL implantation in eyes with deficient capsules in view of the decrease in the learning time and surgical time and risk for complications.
