Prognostic Factors in Patients with Persistent Full-Thickness Idiopathic Macular Holes Treated with Re-Vitrectomy with Autologous Platelet Concentrate
Purpose: To identify the predictors for anatomical and functional
outcome after re-vitrectomy with application of autologous
platelet concentrate (APC) in eyes with persistent
idiopathic macular hole (MH). Methods: Retrospective study
of 103 eyes with persistent MHs after vitrectomy with peeling
of internal limiting membrane (ILM) and expansive gas.
All patients underwent re-vitrectomy with APC and endotamponade.
The anatomical MH closure rate and postoperative
best-corrected visual acuity (BCVA) were evaluated. Further,
predictive factors influencing the success of the surgery
were analyzed. Results: Median BCVA (logMAR) before the
surgery was 1.00 (interquartile range [IQR] 0.80–1.30) and
the median of minimum diameter between hole edges was
508 μm (IQR 387–631). The final closure rate after re-vitrectomy
with APC was 60.2% (62 of 103 eyes). The following
predictors were identified to significantly influence the closure
rate: tractional hole index (THI), axial length, time between
first and second surgery, and the experience of the
surgeon (p < 0.05). Conclusions: Re-vitrectomy with APC led
to the closure of 60.2% of the persistent MHs. The closure
rate negatively correlates with increasing axial length, time
between the first and second surgery, and the decreased
THI. Further, experienced surgeons (with a history of > 100
pars plana vitrectomies with ILM peeling) had significantly
higher closure rates
Changes in stereoacuity following implantable Collamer lens implantation in patients with myopia
The study evaluated the impact of implantable Collamer lens (ICL) implantation on stereoacuity in myopes in a retrospective case series. Ninety-five eyes of 48 patients were recruited. Distance and near stereoacuity were measured using distance Randot stereotest and TNO test, respectively, before surgery and at 4 weeks postoperatively. Mean age of the patients was 23.67 ± 3.7 years. Mean uncorrected distance visual acuity (UDVA) was 1.28 ± 0.37 logarithm of the minimum angle of resolution (logMAR) (median: 1.3; range: 0.3-1.8), and median best-corrected distance visual acuity (BDVA) was 0.18 logMAR (range: 0-0.6). There was a significant improvement in both UDVA and BDVA postsurgery (P < 0.001; Wilcoxon signed rank test). The overall improvement in stereopsis was observed in 15/48 (31.25%) and 13/48 (27.10%) subjects for near and distance, respectively, with no significant difference between the two (P = 0.82; Fisher′s exact test). Among stereoblind individuals, the odd′s ratio for near stereoacuity to improve in comparison to distance stereoacuity was 8.85 (95% confidence interval: 1.68-46.70; P = 0.01). ICL implantation for refractive correction aided stereoacuity improvement in myopes more so for near
Macular hole-associated retinal detachment in Best vitelliform dystrophy: Series of two cases and literature review
Two eyes of 2 patients with macular hole-associated retinal detachment in clinically diagnosed vitelliruptive stage of Best vitelliform dystrophy were surgically managed by 25-gauge sutureless pars plana vitrectomy, internal limiting membrane (ILM) peeling with inverted ILM flap, and short-acting (SF6) gas tamponade. The patients were assessed with respect to best-corrected visual acuity, color fundus photographs, shortwave fundus autofluorescence, and swept source optical coherence tomography. Surgical intervention led to Type 1 closure of macular hole, resolution of retinal detachment, and improvement in vision in both patients
Scleral tunnel phacoemulsification: Approach for eyes with severe microcornea
Cataract surgery in eyes with microcornea is associated with frequent complications such as corneal edema, posterior capsular rent, and risk of unplanned aphakia. We describe an improved surgical technique for the creation of surgical incisions during phacoemulsification in eyes with cataract associated with microcornea. A retrospective analysis of eight patients (8 eyes) operated at our center was undertaken. The mean age of the patients was 29.5 ± 10.9 years. All eyes were operated using the scleral pocket incision for phacoemulsification. This scleral pocket incision was tangential to the limbus and created approximately 2.5 mm behind limbus through which phacoemulsification probe was inserted. Because of the posterior placement of incision, the anterior chamber crowding was minimized. There was no incidence of port-site peripheral corneal edema. Fifty percent eyes developed transient central corneal edema, the intraocular lens in bag was implanted in 5/8 eyes, and none developed Descemet′s membrane detachment. Mean best-corrected visual acuity improved from 1.85 ± 0.38 logarithm of minimum angle of resolution (LogMAR) to 1.26 ± 0.70 LogMAR postoperatively (P = 0.01; paired t-test). Posterior incision placement during phacoemulsification in microcornea helps achieve favorable postoperative outcomes in contrast to outcomes using clear corneal approach described in literature
